3.0 Migration Guide
This page summarizes the changes from CakePHP 2.x that will assist in migrating
a project to 3.0, as well as a reference to get up to date with the changes made
to the core since the CakePHP 2.x branch. Be sure to read the other pages in
this guide for all the new features and API changes.
Requirements
CakePHP 3.x supports PHP Version 5.4.16 and above.
CakePHP 3.x requires the mbstring extension.
CakePHP 3.x requires the intl extension.
Warning
CakePHP 3.0 will not work if you do not meet the above requirements.
Application Directory Layout
The application directory layout has changed and now follows
PSR-4. You should use the
app skeleton project as a reference point
when updating your application.
CakePHP should be installed with Composer
Since CakePHP can no longer be installed via PEAR, or in a shared
directory, those options are no longer supported. Instead you should use
Composer to install CakePHP into your application.
Namespaces
All of CakePHP’s core classes are now namespaced and follow PSR-4 autoloading
specifications. For example src/Cache/Cache.php is namespaced as
Cake\Cache\Cache
. Global constants and helper methods like __()
and debug()
are not namespaced for convenience sake.
Removed Constants
The following deprecated constants have been removed:
IMAGES
CSS
JS
IMAGES_URL
JS_URL
CSS_URL
DEFAULT_LANGUAGE
Configuration
Configuration in CakePHP 3.0 is significantly different than in previous
versions. You should read the Configuration documentation
for how configuration is done in 3.0.
You can no longer use App::build()
to configure additional class paths.
Instead you should map additional paths using your application’s autoloader. See
the section on Additional Class Paths for more information.
Three new configure variables provide the path configuration for plugins,
views and locale files. You can add multiple paths to App.paths.templates
,
App.paths.plugins
, App.paths.locales
to configure multiple paths for
templates, plugins and locale files respectively.
The config key www_root
has been changed to wwwRoot
for consistency. Please adjust
your app.php config file as well as any usage of Configure::read('App.wwwRoot')
.
New ORM
CakePHP 3.0 features a new ORM that has been re-built from the ground up. The
new ORM is significantly different and incompatible with the previous one.
Upgrading to the new ORM will require extensive changes in any application that
is being upgraded. See the new Database Access & ORM documentation for information on how
to use the new ORM.
Basics
LogError()
was removed, it provided no benefit and is rarely/never used.
The following global functions have been removed: config()
, cache()
,
clearCache()
, convertSlashes()
, am()
, fileExistsInPath()
,
sortByKey()
.
Object settings/configuration
Cache
Memcache
engine has been removed, use Cake\Cache\Cache\Engine\Memcached
instead.
Cache engines are now lazy loaded upon first use.
Cake\Cache\Cache::engine()
has been added.
Cake\Cache\Cache::enabled()
has been added. This replaced the
Cache.disable
configure option.
Cake\Cache\Cache::enable()
has been added.
Cake\Cache\Cache::disable()
has been added.
Cache configurations are now immutable. If you need to change configuration
you must first drop the configuration and then re-create it. This prevents
synchronization issues with configuration options.
Cache::set()
has been removed. It is recommended that you create multiple
cache configurations to replace runtime configuration tweaks previously
possible with Cache::set()
.
All CacheEngine
subclasses now implement a config()
method.
Cake\Cache\Cache::readMany()
, Cake\Cache\Cache::deleteMany()
,
and Cake\Cache\Cache::writeMany()
were added.
All Cake\Cache\Cache\CacheEngine
methods now honor/are responsible for handling the
configured key prefix. The Cake\Cache\CacheEngine::write()
no longer permits setting
the duration on write - the duration is taken from the cache engine’s runtime config. Calling a
cache method with an empty key will now throw an InvalidArgumentException
, instead
of returning false
.
Core
App
App::pluginPath()
has been removed. Use CakePlugin::path()
instead.
App::build()
has been removed.
App::location()
has been removed.
App::paths()
has been removed.
App::load()
has been removed.
App::objects()
has been removed.
App::RESET
has been removed.
App::APPEND
has been removed.
App::PREPEND
has been removed.
App::REGISTER
has been removed.
Plugin
Cake\Core\Plugin::load()
does not setup an autoloader unless
you set the autoload
option to true
.
When loading plugins you can no longer provide a callable.
When loading plugins you can no longer provide an array of config files to
load.
Object
The Object
class has been removed. It formerly contained a grab bag of
methods that were used in various places across the framework. The most useful
of these methods have been extracted into traits. You can use the
Cake\Log\LogTrait
to access the log()
method. The
Cake\Routing\RequestActionTrait
provides requestAction()
.
Console
The cake
executable has been moved from the app/Console directory to the
bin directory within the application skeleton. You can now invoke CakePHP’s
console with bin/cake
.
TaskCollection Replaced
This class has been renamed to Cake\Console\TaskRegistry
.
See the section on Registry Objects for more information
on the features provided by the new class. You can use the cake upgrade
rename_collections
to assist in upgrading your code. Tasks no longer have
access to callbacks, as there were never any callbacks to use.
Shell
Additionally all shell methods will be transformed to camel case when invoked.
For example, if you had a hello_world()
method inside a shell and invoked it
with bin/cake my_shell hello_world
, you will need to rename the method
to helloWorld
. There are no changes required in the way you invoke commands.
Shell / Task
Shells and Tasks have been moved from Console/Command
and
Console/Command/Task
to Shell
and Shell/Task
.
ApiShell Removed
The ApiShell was removed as it didn’t provide any benefit over the file source
itself and the online documentation/API.
SchemaShell Removed
The SchemaShell was removed as it was never a complete database migration implementation
and better tools such as Phinx have emerged. It has been replaced by
the CakePHP Migrations Plugin which acts as a wrapper between
CakePHP and Phinx.
BakeShell / TemplateTask
Bake is no longer part of the core source and is superseded by
CakePHP Bake Plugin
Bake templates have been moved under src/Template/Bake.
The syntax of Bake templates now uses erb-style tags (<% %>
) to denote
templating logic, allowing php code to be treated as plain text.
The bake view
command has been renamed bake template
.
Event
The getEventManager()
method, was removed on all objects that had it. An
eventManager()
method is now provided by the EventManagerTrait
. The
EventManagerTrait
contains the logic of instantiating and keeping
a reference to a local event manager.
The Event subsystem has had a number of optional features removed. When
dispatching events you can no longer use the following options:
passParams
This option is now enabled always implicitly. You
cannot turn it off.
break
This option has been removed. You must now stop events.
breakOn
This option has been removed. You must now stop events.
Log
Log configurations are now immutable. If you need to change configuration
you must first drop the configuration and then re-create it. This prevents
synchronization issues with configuration options.
Log engines are now lazily loaded upon the first write to the logs.
Cake\Log\Log::engine()
has been added.
The following methods have been removed from Cake\Log\Log
::
defaultLevels()
, enabled()
, enable()
, disable()
.
You can no longer create custom levels using Log::levels()
.
When configuring loggers you should use 'levels'
instead of 'types'
.
You can no longer specify custom log levels. You must use the default set of
log levels. You should use logging scopes to create custom log files or
specific handling for different sections of your application. Using
a non-standard log level will now throw an exception.
Cake\Log\LogTrait
was added. You can use this trait in your
classes to add the log()
method.
The logging scope passed to Cake\Log\Log::write()
is now
forwarded to the log engines’ write()
method in order to provide better
context to the engines.
Log engines are now required to implement Psr\Log\LogInterface
instead of
Cake’s own LogInterface
. In general, if you extended Cake\Log\Engine\BaseEngine
you just need to rename the write()
method to log()
.
Cake\Log\Engine\FileLog
now writes files in ROOT/logs
instead of ROOT/tmp/logs
.
Routing
Named Parameters
Named parameters were removed in 3.0. Named parameters were added in 1.2.0 as
a ‘pretty’ version of query string parameters. While the visual benefit is
arguable, the problems named parameters created are not.
Named parameters required special handling in CakePHP as well as any PHP or
JavaScript library that needed to interact with them, as named parameters are
not implemented or understood by any library except CakePHP. The additional
complexity and code required to support named parameters did not justify their
existence, and they have been removed. In their place you should use standard
query string parameters or passed arguments. By default Router
will treat
any additional parameters to Router::url()
as query string arguments.
Since many applications will still need to parse incoming URLs containing named
parameters. Cake\Routing\Router::parseNamedParams()
has
been added to allow backwards compatibility with existing URLs.
Router
Named parameters have been removed, see above for more information.
The full_base
option has been replaced with the _full
option.
The ext
option has been replaced with the _ext
option.
_scheme
, _port
, _host
, _base
, _full
, _ext
options added.
String URLs are no longer modified by adding the plugin/controller/prefix names.
The default fallback route handling was removed. If no routes
match a parameter set /
will be returned.
Route classes are responsible for all URL generation including
query string parameters. This makes routes far more powerful and flexible.
Persistent parameters were removed. They were replaced with
Cake\Routing\Router::urlFilter()
which allows
a more flexible way to mutate URLs being reverse routed.
Router::parseExtensions()
has been removed.
Use Cake\Routing\Router::extensions()
instead. This method
must be called before routes are connected. It won’t modify existing
routes.
Router::setExtensions()
has been removed.
Use Cake\Routing\Router::extensions()
instead.
Router::resourceMap()
has been removed.
The [method]
option has been renamed to _method
.
The ability to match arbitrary headers with []
style parameters has been
removed. If you need to parse/match on arbitrary conditions consider using
custom route classes.
Router::promote()
has been removed.
Router::parse()
will now raise an exception when a URL cannot be handled
by any route.
Router::url()
will now raise an exception when no route matches a set of
parameters.
Routing scopes have been introduced. Routing scopes allow you to keep your
routes file DRY and give Router hints on how to optimize parsing & reverse
routing URLs.
Route
CakeRoute
was re-named to Route
.
The signature of match()
has changed to match($url, $context = [])
See Cake\Routing\Route::match()
for information on the new signature.
Dispatcher Filters Configuration Changed
Dispatcher filters are no longer added to your application using Configure
.
You now append them with Cake\Routing\DispatcherFactory
. This
means if your application used Dispatcher.filters
, you should now use
Cake\Routing\DispatcherFactory::add()
.
In addition to configuration changes, dispatcher filters have had some
conventions updated, and features added. See the
Dispatcher Filters documentation for more information.
FilterAssetFilter
Plugin & theme assets handled by the AssetFilter are no longer read via
include
instead they are treated as plain text files. This fixes a number
of issues with JavaScript libraries like TinyMCE and environments with
short_tags enabled.
Support for the Asset.filter
configuration and hooks were removed. This
feature should be replaced with a plugin or dispatcher filter.
Network
Request
CakeRequest
has been renamed to Cake\Network\Request
.
Cake\Network\Request::port()
was added.
Cake\Network\Request::scheme()
was added.
Cake\Network\Request::cookie()
was added.
Cake\Network\Request::$trustProxy
was added. This makes it easier to put
CakePHP applications behind load balancers.
Cake\Network\Request::$data
is no longer merged with the prefixed data
key, as that prefix has been removed.
Cake\Network\Request::env()
was added.
Cake\Network\Request::acceptLanguage()
was changed from static method
to non-static.
Request detector for “mobile” has been removed from the core. Instead the app
template adds detectors for “mobile” and “tablet” using MobileDetect
lib.
The method onlyAllow()
has been renamed to allowMethod()
and no longer accepts “var args”.
All method names need to be passed as first argument, either as string or array of strings.
Sessions
The session class is no longer static, instead the session can be accessed
through the request object. See the Sessions documentation
for using the session object.
Cake\Network\Session
and related session classes have been
moved under the Cake\Network
namespace.
SessionHandlerInterface
has been removed in favor of the one provided by
PHP itself.
The property Session::$requestCountdown
has been removed.
The session checkAgent feature has been removed. It caused a number of bugs
when chrome frame, and flash player are involved.
The conventional sessions database table name is now sessions
instead of
cake_sessions
.
The session cookie timeout is automatically updated in tandem with the timeout
in the session data.
The path for session cookie now defaults to app’s base path instead of “/”.
A new configuration variable Session.cookiePath
has been added to
customize the cookie path.
A new convenience method Cake\Network\Session::consume()
has been added
to allow reading and deleting session data in a single step.
The default value of Cake\Network\Session::clear()
’s argument $renew
has been changed
from true
to false
.
Network\Http
HttpSocket
is now Cake\Network\Http\Client
.
HttpClient has been re-written from the ground up. It has a simpler/easier to
use API, support for new authentication systems like OAuth, and file uploads.
It uses PHP’s stream APIs so there is no requirement for cURL. See the
Http Client documentation for more information.
Network\Email
Cake\Network\Email\Email::config()
is now used to define
configuration profiles. This replaces the EmailConfig
classes in previous
versions.
Cake\Network\Email\Email::profile()
replaces config()
as
the way to modify per instance configuration options.
Cake\Network\Email\Email::drop()
has been added to allow the
removal of email configuration.
Cake\Network\Email\Email::configTransport()
has been added to allow the
definition of transport configurations. This change removes transport options
from delivery profiles and allows you to re-use transports across email
profiles.
Cake\Network\Email\Email::dropTransport()
has been added to allow the
removal of transport configuration.
Controller
Controller
The $helpers
, $components
properties are now merged
with all parent classes not just AppController
and the plugin
AppController. The properties are merged differently now as well. Instead of
all settings in all classes being merged together, the configuration defined
in the child class will be used. This means that if you have some
configuration defined in your AppController, and some configuration defined in
a subclass, only the configuration in the subclass will be used.
Controller::httpCodes()
has been removed, use
Cake\Network\Response::httpCodes()
instead.
Controller::disableCache()
has been removed, use
Cake\Network\Response::disableCache()
instead.
Controller::flash()
has been removed. This method was rarely used in real
applications and served no purpose anymore.
Controller::validate()
and Controller::validationErrors()
have been
removed. They were left over methods from the 1.x days where the concerns of
models + controllers were far more intertwined.
Controller::loadModel()
now loads table objects.
The Controller::$scaffold
property has been removed. Dynamic scaffolding
has been removed from CakePHP core. An improved scaffolding plugin, named CRUD, can be found here: https://github.com/FriendsOfCake/crud
The Controller::$ext
property has been removed. You now have to extend and
override the View::$_ext
property if you want to use a non-default view file
extension.
The Controller::$methods
property has been removed. You should now use
Controller::isAction()
to determine whether or not a method name is an
action. This change was made to allow easier customization of what is and is
not counted as an action.
The Controller::$Components
property has been removed and replaced with
_components
. If you need to load components at runtime you should use
$this->loadComponent()
on your controller.
The signature of Cake\Controller\Controller::redirect()
has been
changed to Controller::redirect(string|array $url, int $status = null)
.
The 3rd argument $exit
has been dropped. The method can no longer send
response and exit script, instead it returns a Response
instance with
appropriate headers set.
The base
, webroot
, here
, data
, action
, and params
magic properties have been removed. You should access all of these properties
on $this->request
instead.
Underscore prefixed controller methods like _someMethod()
are no longer
treated as private methods. Use proper visibility keywords instead. Only
public methods can be used as controller actions.
Scaffold Removed
The dynamic scaffolding in CakePHP has been removed from CakePHP core. It was
infrequently used, and never intended for production use. An improved
scaffolding plugin, named CRUD, can be found here:
https://github.com/FriendsOfCake/crud
ComponentCollection Replaced
This class has been renamed to Cake\Controller\ComponentRegistry
.
See the section on Registry Objects for more information
on the features provided by the new class. You can use the cake upgrade
rename_collections
to assist in upgrading your code.
Component
The _Collection
property is now _registry
. It contains an instance
of Cake\Controller\ComponentRegistry
now.
All components should now use the config()
method to get/set
configuration.
Default configuration for components should be defined in the
$_defaultConfig
property. This property is automatically merged with any
configuration provided to the constructor.
Configuration options are no longer set as public properties.
The Component::initialize()
method is no longer an event listener.
Instead, it is a post-constructor hook like Table::initialize()
and
Controller::initialize()
. The new Component::beforeFilter()
method is
bound to the same event that Component::initialize()
used to be. The
initialize method should have the following signature initialize(array
$config)
.
Controller\Components
CookieComponent
Uses Cake\Network\Request::cookie()
to read cookie data,
this eases testing, and allows for ControllerTestCase to set cookies.
Cookies encrypted in previous versions of CakePHP using the cipher()
method
are now un-readable because Security::cipher()
has been removed. You will
need to re-encrypt cookies with the rijndael()
or aes()
method before upgrading.
CookieComponent::type()
has been removed and replaced with configuration
data accessed through config()
.
write()
no longer takes encryption
or expires
parameters. Both of
these are now managed through config data. See
Cookie for more information.
The path for cookies now defaults to app’s base path instead of “/”.
AuthComponent
Default
is now the default password hasher used by authentication classes.
It uses exclusively the bcrypt hashing algorithm. If you want to continue using
SHA1 hashing used in 2.x use 'passwordHasher' => 'Weak'
in your authenticator configuration.
A new FallbackPasswordHasher
was added to help users migrate old passwords
from one algorithm to another. Check AuthComponent’s documentation for more
info.
BlowfishAuthenticate
class has been removed. Just use FormAuthenticate
BlowfishPasswordHasher
class has been removed. Use
DefaultPasswordHasher
instead.
The loggedIn()
method has been removed. Use user()
instead.
Configuration options are no longer set as public properties.
The methods allow()
and deny()
no longer accept “var args”. All method names need
to be passed as first argument, either as string or array of strings.
The method login()
has been removed and replaced by setUser()
instead.
To login a user you now have to call identify()
which returns user info upon
successful identification and then use setUser()
to save the info to
session for persistence across requests.
BaseAuthenticate::_password()
has been removed. Use a PasswordHasher
class instead.
BaseAuthenticate::logout()
has been removed.
AuthComponent
now triggers two events Auth.afterIdentify
and
Auth.logout
after a user has been identified and before a user is
logged out respectively. You can set callback functions for these events by
returning a mapping array from implementedEvents()
method of your
authenticate class.
ACL related classes were moved to a separate plugin. Password hashers, Authentication and
Authorization providers where moved to the \Cake\Auth
namespace. You are
required to move your providers and hashers to the App\Auth
namespace as
well.
RequestHandlerComponent
The following methods have been removed from RequestHandler component::
isAjax()
, isFlash()
, isSSL()
, isPut()
, isPost()
, isGet()
, isDelete()
.
Use the Cake\Network\Request::is()
method instead with relevant argument.
RequestHandler::setContent()
was removed, use Cake\Network\Response::type()
instead.
RequestHandler::getReferer()
was removed, use Cake\Network\Request::referer()
instead.
RequestHandler::getClientIP()
was removed, use Cake\Network\Request::clientIp()
instead.
RequestHandler::getAjaxVersion()
was removed.
RequestHandler::mapType()
was removed, use Cake\Network\Response::mapType()
instead.
Configuration options are no longer set as public properties.
SecurityComponent
The following methods and their related properties have been removed from Security component:
requirePost()
, requireGet()
, requirePut()
, requireDelete()
.
Use the Cake\Network\Request::allowMethod()
instead.
SecurityComponent::$disabledFields()
has been removed, use
SecurityComponent::$unlockedFields()
.
The CSRF related features in SecurityComponent have been extracted and moved
into a separate CsrfComponent. This allows you to use CSRF protection
without having to use form tampering prevention.
Configuration options are no longer set as public properties.
The methods requireAuth()
and requireSecure()
no longer accept “var args”.
All method names need to be passed as first argument, either as string or array of strings.
Error
Custom ExceptionRenderers are now expected to either return
a Cake\Network\Response
object or string when rendering errors. This means
that any methods handling specific exceptions must return a response or string
value.
Model
The Model layer in 2.x has been entirely re-written and replaced. You should
review the New ORM Upgrade Guide for information on how to use the
new ORM.
The Model
class has been removed.
The BehaviorCollection
class has been removed.
The DboSource
class has been removed.
The Datasource
class has been removed.
The various datasource classes have been removed.
ConnectionManager
ConnectionManager has been moved to the Cake\Datasource
namespace.
ConnectionManager has had the following methods removed:
sourceList
getSourceName
loadDataSource
enumConnectionObjects
Database\ConnectionManager::config()
has been added and is
now the only way to configure connections.
Database\ConnectionManager::get()
has been added. It
replaces getDataSource()
.
Database\ConnectionManager::configured()
has been added. It
and config()
replace sourceList()
& enumConnectionObjects()
with
a more standard and consistent API.
ConnectionManager::create()
has been removed.
It can be replaced by config($name, $config)
and get($name)
.
TreeBehavior
The TreeBehavior was completely re-written to use the new ORM. Although it works
the same as in 2.x, a few methods were renamed or removed:
TreeBehavior::children()
is now a custom finder find('children')
.
TreeBehavior::generateTreeList()
is now a custom finder find('treeList')
.
TreeBehavior::getParentNode()
was removed.
TreeBehavior::getPath()
is now a custom finder find('path')
.
TreeBehavior::reorder()
was removed.
TreeBehavior::verify()
was removed.
TestSuite
TestCase
The following assertion methods have been removed as they have long been deprecated and replaced by
their new PHPUnit counterpart:
assertEqual()
in favor of assertEquals()
assertNotEqual()
in favor of assertNotEquals()
assertIdentical()
in favor of assertSame()
assertNotIdentical()
in favor of assertNotSame()
assertPattern()
in favor of assertRegExp()
assertNoPattern()
in favor of assertNotRegExp()
assertReference()
if favor of assertSame()
assertIsA()
in favor of assertInstanceOf()
Note that some methods have switched the argument order, e.g. assertEqual($is, $expected)
should now be
assertEquals($expected, $is)
.
The following assertion methods have been deprecated and will be removed in the future:
Both method replacements also switched the argument order for a consistent assert method API
with $expected
as first argument.
The following assertion methods have been added:
View
Themes are now Basic Plugins
Having themes and plugins as ways to create modular application components has
proven to be limited, and confusing. In CakePHP 3.0, themes no longer reside
inside the application. Instead they are standalone plugins. This solves
a few problems with themes:
Both these issues are solved by converting themes into plugins.
View Folders Renamed
The folders containing view files now go under src/Template instead of src/View.
This was done to separate the view files from files containing php classes (eg. Helpers, View classes).
The following View folders have been renamed to avoid naming collisions with controller names:
HelperCollection Replaced
This class has been renamed to Cake\View\HelperRegistry
.
See the section on Registry Objects for more information
on the features provided by the new class. You can use the cake upgrade
rename_collections
to assist in upgrading your code.
View Class
The plugin
key has been removed from $options
argument of Cake\View\View::element()
.
Specify the element name as SomePlugin.element_name
instead.
View::getVar()
has been removed, use Cake\View\View::get()
instead.
View::$ext
has been removed and instead a protected property View::$_ext
has been added.
View::addScript()
has been removed. Use Using View Blocks instead.
The base
, webroot
, here
, data
, action
, and params
magic properties have been removed. You should access all of these properties
on $this->request
instead.
View::start()
no longer appends to an existing block. Instead it will
overwrite the block content when end is called. If you need to combine block
contents you should fetch the block content when calling start a second time,
or use the capturing mode of append()
.
View::prepend()
no longer has a capturing mode.
View::startIfEmpty()
has been removed. Now that start() always overwrites
startIfEmpty serves no purpose.
The View::$Helpers
property has been removed and replaced with
_helpers
. If you need to load helpers at runtime you should use
$this->addHelper()
in your view files.
View
will now raise Cake\View\Exception\MissingTemplateException
when
templates are missing instead of MissingViewException
.
JsonView
By default JSON data will have HTML entities encoded now. This prevents
possible XSS issues when JSON view content is embedded in HTML files.
Cake\View\JsonView
now supports the _jsonOptions
view
variable. This allows you to configure the bit-mask options used when generating
JSON.
View\Helper
The $settings
property is now called $_config
and should be accessed
through the config()
method.
Configuration options are no longer set as public properties.
Helper::clean()
was removed. It was never robust enough
to fully prevent XSS. instead you should escape content with h
or
use a dedicated library like htmlPurifier.
Helper::output()
was removed. This method was
deprecated in 2.x.
Methods Helper::webroot()
, Helper::url()
, Helper::assetUrl()
,
Helper::assetTimestamp()
have been moved to new Cake\View\Helper\UrlHelper
helper. Helper::url()
is now available as Cake\View\Helper\UrlHelper::build()
.
Magic accessors to deprecated properties have been removed. The following
properties now need to be accessed from the request object:
base
here
webroot
data
action
params
Helper
Helper has had the following methods removed:
These methods were part used only by FormHelper, and part of the persistent
field features that have proven to be problematic over time. FormHelper no
longer relies on these methods and the complexity they provide is not necessary
anymore.
The following methods have been removed:
These methods can now be found on the StringTemplate
class that helpers
frequently use. See the StringTemplateTrait
for an easy way to integrate
string templates into your own helpers.
HtmlHelper
HtmlHelper::useTag()
has been removed, use tag()
instead.
HtmlHelper::loadConfig()
has been removed. Customizing the tags can now be
done using templates()
or the templates
setting.
The second parameter $options
for HtmlHelper::css()
now always requires an array as documented.
The first parameter $data
for HtmlHelper::style()
now always requires an array as documented.
The inline
parameter has been removed from meta(), css(), script(), scriptBlock()
methods. You should use the block
option instead. Setting block =>
true
will emulate the previous behavior.
HtmlHelper::meta()
now requires $type
to be a string. Additional options can
further on be passed as $options
.
HtmlHelper::nestedList()
now requires $options
to be an array. The forth argument for the tag type
has been removed and included in the $options
array.
The $confirmMessage
argument of Cake\View\Helper\HtmlHelper::link()
has been removed. You should now use key confirm
in $options
to specify
the message.
PaginatorHelper
link()
has been removed. It was no longer used by the helper internally.
It had low usage in user land code, and no longer fit the goals of the helper.
next()
no longer has ‘class’, or ‘tag’ options. It no longer has disabled
arguments. Instead templates are used.
prev()
no longer has ‘class’, or ‘tag’ options. It no longer has disabled
arguments. Instead templates are used.
first()
no longer has ‘after’, ‘ellipsis’, ‘separator’, ‘class’, or ‘tag’ options.
last()
no longer has ‘after’, ‘ellipsis’, ‘separator’, ‘class’, or ‘tag’ options.
numbers()
no longer has ‘separator’, ‘tag’, ‘currentTag’, ‘currentClass’,
‘class’, ‘tag’, ‘ellipsis’ options. These options are now facilitated through
templates. It also requires the $options
parameter to be an array now.
The %page%
style placeholders have been removed from Cake\View\Helper\PaginatorHelper::counter()
.
Use {{page}}
style placeholders instead.
url()
has been renamed to generateUrl()
to avoid method declaration clashes with Helper::url()
.
By default all links and inactive texts are wrapped in <li>
elements. This
helps make CSS easier to write, and improves compatibility with popular CSS
frameworks.
Instead of the various options in each method, you should use the templates
feature. See the PaginatorHelper Templates documentation for
information on how to use templates.
TimeHelper
TimeHelper::__set()
, TimeHelper::__get()
, and TimeHelper::__isset()
were
removed. These were magic methods for deprecated attributes.
TimeHelper::serverOffset()
has been removed. It promoted incorrect time math practices.
TimeHelper::niceShort()
has been removed.
CacheHelper Removed
CacheHelper has been removed. The caching functionality it provided was
non-standard, limited and incompatible with non-HTML layouts and data views.
These limitations meant a full rebuild would be necessary. Edge Side Includes
have become a standardized way to implement the functionality CacheHelper used
to provide. However, implementing Edge Side Includes in PHP has a number of
limitations and edge cases. Instead of building a sub-par solution, we recommend
that developers needing full response caching use Varnish or Squid instead.
I18n
The I18n subsystem was completely rewritten. In general, you can expect the same
behavior as in previous versions, specifically if you are using the __()
family of functions.
Internally, the I18n
class uses Aura\Intl
, and appropriate methods are
exposed to access the specific features of this library. For this reason most
methods inside I18n
were removed or renamed.
Due to the use of ext/intl
, the L10n class was completely removed. It
provided outdated and incomplete data in comparison to the data available from
the Locale
class in PHP.
The default application language will no longer be changed automatically by the
browser accepted language nor by having the Config.language
value set in the
browser session. You can, however, use a dispatcher filter to get automatic
language switching from the Accept-Language
header sent by the browser:
// In config/bootstrap.php
DispatcherFactory::addFilter('LocaleSelector');
There is no built-in replacement for automatically selecting the language by
setting a value in the user session.
The default formatting function for translated messages is no longer
sprintf
, but the more advanced and feature rich MessageFormatter
class.
In general you can rewrite placeholders in messages as follows:
// Before:
__('Today is a %s day in %s', 'Sunny', 'Spain');
// After:
__('Today is a {0} day in {1}', 'Sunny', 'Spain');
You can avoid rewriting your messages by using the old sprintf
formatter:
I18n::defaultFormatter('sprintf');
Additionally, the Config.language
value was removed and it can no longer be
used to control the current language of the application. Instead, you can use
the I18n
class:
// Before
Configure::write('Config.language', 'fr_FR');
// Now
I18n::setLocale('en_US');
The methods below have been moved:
From Cake\I18n\Multibyte::utf8()
to Cake\Utility\Text::utf8()
From Cake\I18n\Multibyte::ascii()
to Cake\Utility\Text::ascii()
From Cake\I18n\Multibyte::checkMultibyte()
to Cake\Utility\Text::isMultibyte()
Since CakePHP now requires the mbstring extension, the
Multibyte
class has been removed.
Error messages throughout CakePHP are no longer passed through I18n
functions. This was done to simplify the internals of CakePHP and reduce
overhead. The developer facing messages are rarely, if ever, actually translated -
so the additional overhead reaps very little benefit.
Testing
The TestShell
has been removed. CakePHP, the application skeleton and
newly baked plugins all use phpunit
to run tests.
The webrunner (webroot/test.php) has been removed. CLI adoption has greatly
increased since the initial release of 2.x. Additionaly, CLI runners offer
superior integration with IDE’s and other automated tooling.
If you find yourself in need of a way to run tests from a browser you should
checkout VisualPHPUnit. It
offers many additional features over the old webrunner.
ControllerTestCase
is deprecated and will be removed for CakePHP 3.0.0.
You should use the new Controller Integration Testing features instead.
Fixtures should now be referenced using their plural form:
// Instead of
$fixtures = ['app.article'];
// You should use
$fixtures = ['app.articles'];
Utility
Set Class Removed
The Set class has been removed, you should use the Hash class instead now.
Folder & File
The folder and file classes have been renamed:
Inflector
The default value for $replacement
argument of Cake\Utility\Inflector::slug()
has been changed from underscore (_
) to dash (-
). Using dashes to
separate words in URLs is the popular choice and also recommended by Google.
Transliterations for Cake\Utility\Inflector::slug()
have changed.
If you use custom transliterations you will need to update your code. Instead
of regular expressions, transliterations use simple string replacement. This
yielded significant performance improvements:
// Instead of
Inflector::rules('transliteration', [
'/ä|æ/' => 'ae',
'/å/' => 'aa'
]);
// You should use
Inflector::rules('transliteration', [
'ä' => 'ae',
'æ' => 'ae',
'å' => 'aa'
]);
Separate set of uninflected and irregular rules for pluralization and
singularization have been removed. Instead we now have a common list for each.
When using Cake\Utility\Inflector::rules()
with type ‘singular’
and ‘plural’ you can no longer use keys like ‘uninflected’, ‘irregular’ in
$rules
argument array.
You can add / overwrite the list of uninflected and irregular rules using
Cake\Utility\Inflector::rules()
by using values ‘uninflected’ and
‘irregular’ for $type
argument.
Security
Security::cipher()
has been removed. It is insecure and promoted bad
cryptographic practices. You should use Security::encrypt()
instead.
The Configure value Security.cipherSeed
is no longer required. With the
removal of Security::cipher()
it serves no use.
Backwards compatibility in Cake\Utility\Security::rijndael()
for values encrypted prior
to CakePHP 2.3.1 has been removed. You should re-encrypt values using
Security::encrypt()
and a recent version of CakePHP 2.x before migrating.
The ability to generate a blowfish hash has been removed. You can no longer use type
“blowfish” for Security::hash()
. One should just use PHP’s password_hash()
and password_verify() to generate and verify blowfish hashes. The compability
library ircmaxell/password-compat
which is installed along with CakePHP provides these functions for PHP < 5.5.
OpenSSL is now used over mcrypt when encrypting/decrypting data. This change
provides better performance and future proofs CakePHP against distros dropping
support for mcrypt.
Security::rijndael()
is deprecated and only available when using mcrypt.
Warning
Data encrypted with Security::encrypt() in previous versions is not
compatible with the openssl implementation. You should set the
implementation to mcrypt when upgrading.
Time
CakeTime
has been renamed to Cake\I18n\Time
.
CakeTime::serverOffset()
has been removed. It promoted incorrect time math practises.
CakeTime::niceShort()
has been removed.
CakeTime::convert()
has been removed.
CakeTime::convertSpecifiers()
has been removed.
CakeTime::dayAsSql()
has been removed.
CakeTime::daysAsSql()
has been removed.
CakeTime::fromString()
has been removed.
CakeTime::gmt()
has been removed.
CakeTime::toATOM()
has been renamed to toAtomString
.
CakeTime::toRSS()
has been renamed to toRssString
.
CakeTime::toUnix()
has been renamed to toUnixString
.
CakeTime::wasYesterday()
has been renamed to isYesterday
to match the rest
of the method naming.
CakeTime::format()
Does not use sprintf
format strings anymore, you can use
i18nFormat
instead.
Time::timeAgoInWords()
now requires $options
to be an array.
Time is not a collection of static methods anymore, it extends DateTime
to
inherit all its methods and adds location aware formatting functions with the
help of the intl
extension.
In general, expressions looking like this:
CakeTime::aMethod($date);
Can be migrated by rewriting it to:
(new Time($date))->aMethod();
Number
The Number library was rewritten to internally use the NumberFormatter
class.
Xml
Xml::build()
now requires $options
to be an array.
Xml::build()
no longer accepts a URL. If you need to create an XML
document from a URL, use Http\Client.
