This document is for a version of CakePHP that is no longer supported. Please upgrade to a newer release!
CakeEmail
is a new class to send email. With this
class you can send email from any place in your application. In addition to
using the EmailComponent from your controller, you can also send mail from
Shells and Models.
This class replaces the EmailComponent
and gives more flexibility
in sending emails. For example, you can create your own transports to send
email instead of using the provided SMTP and Mail transports.
First of all, you should ensure the class is loaded using App::uses()
:
App::uses('CakeEmail', 'Network/Email');
Using CakeEmail is similar to using EmailComponent
. But instead of
using attributes you use methods. Example:
$Email = new CakeEmail();
$Email->from(array('[email protected]' => 'My Site'));
$Email->to('[email protected]');
$Email->subject('About');
$Email->send('My message');
To simplify things, all of the setter methods return the instance of class. You can re-write the above code as:
$Email = new CakeEmail();
$Email->from(array('[email protected]' => 'My Site'))
->to('[email protected]')
->subject('About')
->send('My message');
When sending email on behalf of other people it’s often a good idea to define the
original sender using the Sender header. You can do so using sender()
:
$Email = new CakeEmail();
$Email->sender('[email protected]', 'MyApp emailer');
Note
It’s also a good idea to set the envelope sender when sending mail on another person’s behalf. This prevents them from getting any messages about deliverability.
Similar to database configuration, email configuration can be centralized in a class.
Create the file app/Config/email.php
with the class EmailConfig
.
The app/Config/email.php.default
has an example of this file.
CakeEmail
will create an instance of the EmailConfig
class to access the
config. If you have dynamic data to put in the configs, you can use the
constructor to do that:
class EmailConfig {
public function __construct() {
// Do conditional assignments here.
}
}
It is not required to create app/Config/email.php
, CakeEmail
can be used
without it and use respective methods to set all configurations separately or
load an array of configs.
To load a config from EmailConfig
you can use the config()
method or pass it
to the constructor of CakeEmail
:
$Email = new CakeEmail();
$Email->config('default');
//or in constructor::
$Email = new CakeEmail('default');
// Implicit 'default' config used as of 2.7
$Email = new CakeEmail();
Instead of passing a string which matches the configuration name in EmailConfig
you can also just load an array of configs:
$Email = new CakeEmail();
$Email->config(array('from' => '[email protected]', 'transport' => 'MyCustom'));
//or in constructor::
$Email = new CakeEmail(array('from' => '[email protected]', 'transport' => 'MyCustom'));
Note
Use $Email->config()
or the constructor to set the log level to log email headers and message.
Using $Email->config(array('log' => true));
will use LOG_DEBUG. See also CakeLog::write()
You can configure SSL SMTP servers such as Gmail. To do so, prefix the host with
'ssl://'
and configure the port value accordingly. Example:
class EmailConfig {
public $gmail = array(
'host' => 'ssl://smtp.gmail.com',
'port' => 465,
'username' => '[email protected]',
'password' => 'secret',
'transport' => 'Smtp'
);
}
You can also use tls://
to prefer TLS for connection level encryption.
Warning
You will need to have access for less secure apps enabled in your Google account for this to work: Allowing less secure apps to access your account.
Note
To use either the ssl:// or tls:// feature, you will need to have the SSL configured in your PHP install.
As of 2.3.0 you can also enable STARTTLS SMTP extension using the tls
option:
class EmailConfig {
public $gmail = array(
'host' => 'smtp.gmail.com',
'port' => 465,
'username' => '[email protected]',
'password' => 'secret',
'transport' => 'Smtp',
'tls' => true
);
}
The above configuration would enable STARTTLS communication for email messages.
New in version 2.3: Support for TLS delivery was added in 2.3
The following configuration keys are used:
'from'
: Email or array of sender. See CakeEmail::from()
.
'sender'
: Email or array of real sender. See CakeEmail::sender()
.
'to'
: Email or array of destination. See CakeEmail::to()
.
'cc'
: Email or array of carbon copy. See CakeEmail::cc()
.
'bcc'
: Email or array of blind carbon copy. See CakeEmail::bcc()
.
'replyTo'
: Email or array to reply the e-mail. See CakeEmail::replyTo()
.
'readReceipt'
: Email address or an array of addresses to receive the
receipt of read. See CakeEmail::readReceipt()
.
'returnPath'
: Email address or and array of addresses to return if have
some error. See CakeEmail::returnPath()
.
'messageId'
: Message ID of e-mail. See CakeEmail::messageId()
.
'subject'
: Subject of the message. See CakeEmail::subject()
.
'message'
: Content of message. Do not set this field if you are using rendered content.
'headers'
: Headers to be included. See CakeEmail::setHeaders()
.
'viewRender'
: If you are using rendered content, set the view class name.
See CakeEmail::viewRender()
.
'template'
: If you are using rendered content, set the template name. See
CakeEmail::template()
.
'theme'
: Theme used when rendering template. See CakeEmail::theme()
.
'layout'
: If you are using rendered content, set the layout to render. If
you want to render a template without layout, set this field to null. See
CakeEmail::template()
.
'viewVars'
: If you are using rendered content, set the array with
variables to be used in the view. See CakeEmail::viewVars()
.
'attachments'
: List of files to attach. See CakeEmail::attachments()
.
'emailFormat'
: Format of email (html, text or both). See CakeEmail::emailFormat()
.
'transport'
: Transport name. See CakeEmail::transport()
.
'helpers'
: Array of helpers used in the email template.
All of these configurations are optional, except 'from'
. If you put more
configurations in this array, the configurations will be used in the
CakeEmail::config()
method and passed to the transport class config()
.
For example, if you are using the SMTP transport, you should pass the host, port and
other configurations.
Note
The values of above keys using Email or array, like from, to, cc, etc will be passed
as first parameter of corresponding methods. The equivalent for:
CakeEmail::from('my@example.com', 'My Site')
would be defined as 'from' => array('my@example.com' => 'My Site')
in your config.
In CakeEmail
you are free to set whatever headers you want. When migrating
to use CakeEmail, do not forget to put the X-
prefix in your headers.
See CakeEmail::setHeaders()
and CakeEmail::addHeaders()
Emails are often much more than just a simple text message. In order to facilitate that, CakePHP provides a way to send emails using CakePHP’s view layer.
The templates for emails reside in a special folder in your applications
View
directory called Emails
. Email views can also use layouts,
and elements just like normal views:
$Email = new CakeEmail();
$Email->template('welcome', 'fancy')
->emailFormat('html')
->to('[email protected]')
->from('[email protected]')
->send();
The above would use app/View/Emails/html/welcome.ctp
for the view,
and app/View/Layouts/Emails/html/fancy.ctp
for the layout. You can
send multipart templated email messages as well:
$Email = new CakeEmail();
$Email->template('welcome', 'fancy')
->emailFormat('both')
->to('[email protected]')
->from('[email protected]')
->send();
This would use the following view files:
app/View/Emails/text/welcome.ctp
app/View/Layouts/Emails/text/fancy.ctp
app/View/Emails/html/welcome.ctp
app/View/Layouts/Emails/html/fancy.ctp
When sending templated emails you have the option of sending either
text
, html
or both
.
You can set view variables with CakeEmail::viewVars()
:
$Email = new CakeEmail('templated');
$Email->viewVars(array('value' => 12345));
In your email templates you can use these with:
<p>Here is your value: <b><?php echo $value; ?></b></p>
You can use helpers in emails as well, much like you can in normal view files.
By default only the HtmlHelper
is loaded. You can load additional
helpers using the helpers()
method:
$Email->helpers(array('Html', 'Custom', 'Text'));
When setting helpers be sure to include ‘Html’ or it will be removed from the helpers loaded in your email template.
If you want to send email using templates in a plugin you can use the familiar plugin syntax to do so:
$Email = new CakeEmail();
$Email->template('Blog.new_comment', 'Blog.auto_message');
The above would use templates from the Blog plugin as an example.
In some cases, you might need to override the default template provided by plugins.
You can do this using themes by telling CakeEmail to use appropriate theme using
CakeEmail::theme()
method:
$Email = new CakeEmail();
$Email->template('Blog.new_comment', 'Blog.auto_message');
$Email->theme('TestTheme');
This allows you to override the new_comment template in your theme without modifying
the Blog plugin. The template file needs to be created in the following path:
APP/View/Themed/TestTheme/Blog/Emails/text/new_comment.ctp
.
You can attach files to email messages as well. There are a few different formats depending on what kind of files you have, and how you want the filenames to appear in the recipient’s mail client:
String: $Email->attachments('/full/file/path/file.png')
will attach this
file with the name file.png.
Array: $Email->attachments(array('/full/file/path/file.png'))
will have
the same behavior as using a string.
Array with key:
$Email->attachments(array('photo.png' => '/full/some_hash.png'))
will
attach some_hash.png with the name photo.png. The recipient will see
photo.png, not some_hash.png.
Nested arrays:
$Email->attachments(array(
'photo.png' => array(
'file' => '/full/some_hash.png',
'mimetype' => 'image/png',
'contentId' => 'my-unique-id'
)
));
The above will attach the file with different mimetype and with custom Content ID (when set the content ID the attachment is transformed to inline). The mimetype and contentId are optional in this form.
4.1. When you are using the contentId
, you can use the file in the HTML
body like <img src="cid:my-content-id">
.
4.2. You can use the contentDisposition
option to disable the
Content-Disposition
header for an attachment. This is useful when
sending ical invites to clients using outlook.
4.3 Instead of the file
option you can provide the file contents as
a string using the data
option. This allows you to attach files without
needing file paths to them.
Changed in version 2.3: The contentDisposition
option was added.
Changed in version 2.4: The data
option was added.
Transports are classes designed to send the e-mail over some protocol or method. CakePHP supports the Mail (default), Debug and SMTP transports.
To configure your method, you must use the CakeEmail::transport()
method or have the transport in your configuration.
You are able to create your custom transports to integrate with others email
systems (like SwiftMailer). To create your transport, first create the file
app/Lib/Network/Email/ExampleTransport.php
(where Example is the name of your
transport). To start off your file should look like:
App::uses('AbstractTransport', 'Network/Email');
class ExampleTransport extends AbstractTransport {
public function send(CakeEmail $Email) {
// magic inside!
}
}
You must implement the method send(CakeEmail $Email)
with your custom logic.
Optionally, you can implement the config($config)
method. config()
is
called before send() and allows you to accept user configurations. By default,
this method puts the configuration in protected attribute $_config
.
If you need to call additional methods on the transport before send, you can use
CakeEmail::transportClass()
to get an instance of the transport.
Example:
$yourInstance = $Email->transport('your')->transportClass();
$yourInstance->myCustomMethod();
$Email->send();
If you are having validation issues when sending to non-compliant addresses, you can relax the pattern used to validate email addresses. This is sometimes necessary when dealing with some Japanese ISP’s:
$email = new CakeEmail('default');
// Relax the email pattern, so you can send
// to non-conformant addresses.
$email->emailPattern($newPattern);
New in version 2.4.
Sometimes you need a quick way to fire off an email, and you don’t necessarily
want do setup a bunch of configuration ahead of time.
CakeEmail::deliver()
is intended for that purpose.
You can create your configuration in EmailConfig
, or use an array with all
options that you need and use the static method CakeEmail::deliver()
.
Example:
CakeEmail::deliver('[email protected]', 'Subject', 'Message', array('from' => '[email protected]'));
This method will send an email to you@example.com, from me@example.com with subject Subject and content Message.
The return of deliver()
is a CakeEmail
instance with all
configurations set. If you do not want to send the email right away, and wish
to configure a few things before sending, you can pass the 5th parameter as
false.
The 3rd parameter is the content of message or an array with variables (when using rendered content).
The 4th parameter can be an array with the configurations or a string with the
name of configuration in EmailConfig
.
If you want, you can pass the to, subject and message as null and do all
configurations in the 4th parameter (as array or using EmailConfig
).
Check the list of configurations to see all accepted configs.
Changed in version 2.2: The domain()
method was added in 2.2
When sending emails within a CLI script (Shells, Tasks, …) you should manually set the domain name for CakeEmail to use. The domain name is used as the host name for the message id (since there is no host name in a CLI environment):
$Email->domain('www.example.org');
// Results in message ids like ``<[email protected]>`` (valid)
// instead of `<UUID@>`` (invalid)
A valid message id can help to prevent emails ending up in spam folders. If you
are generating links in your email bodies you will also need to set the
App.fullBaseUrl
configure value.
