The role of the HtmlHelper in CakePHP is to make HTML-related options easier, faster, and more resilient to change. Using this helper will enable your application to be more light on its feet, and more flexible on where it is placed in relation to the root of a domain.
Many HtmlHelper methods include a $options
parameter,
that allow you to tack on any extra attributes on your tags. Here
are a few examples of how to use the $options parameter:
Desired attributes: <tag class="someClass" />
Array parameter: array('class' => 'someClass')
Desired attributes: <tag name="foo" value="bar" />
Array parameter: array('name' => 'foo', 'value' => 'bar')
Note
The HtmlHelper is available in all views by default. If you’re getting an error informing you that it isn’t there, it’s usually due to its name being missing from a manually configured $helpers controller variable.
The most important task the HtmlHelper accomplishes is creating well formed markup. Don’t be afraid to use it often - you can cache views in CakePHP in order to save some CPU cycles when views are being rendered and delivered. This section will cover some of the methods of the HtmlHelper and how to use them.
$charset (string
) – Desired character set. If null, the value of
App.encoding
will be used.
Used to create a meta tag specifying the document’s character. Defaults to UTF-8
Example use:
echo $this->Html->charset();
Will output:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
Alternatively,
echo $this->Html->charset('ISO-8859-1');
Will output:
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
Changed in version 2.4.
$path (mixed
) – Either a string of the CSS file to link, or an array with multiple files
$options (array
) – An array of options or html attributes.
Creates a link(s) to a CSS style-sheet. If key ‘inline’ is set to
false in $options
parameter, the link tags are added to the
css
block which you can print inside the head
tag of the document.
You can use the block
option to control which block the link element
will be appended to. By default it will append to the css
block.
If key ‘rel’ in $options
array is set to ‘import’ the stylesheet will be imported.
This method of CSS inclusion assumes that the CSS file specified resides inside the /app/webroot/css directory if path doesn’t start with a ‘/’.
echo $this->Html->css('forms');
Will output:
<link rel="stylesheet" type="text/css" href="/css/forms.css" />
The first parameter can be an array to include multiple files.
echo $this->Html->css(array('forms', 'tables', 'menu'));
Will output:
<link rel="stylesheet" type="text/css" href="/css/forms.css" />
<link rel="stylesheet" type="text/css" href="/css/tables.css" />
<link rel="stylesheet" type="text/css" href="/css/menu.css" />
You can include CSS files from any loaded plugin using
plugin syntax. To include
app/Plugin/DebugKit/webroot/css/toolbar.css
you could use the following:
echo $this->Html->css('DebugKit.toolbar.css');
If you want to include a CSS file which shares a name with a loaded
plugin you can do the following. For example if you had a Blog
plugin,
and also wanted to include app/webroot/css/Blog.common.css
, you would:
Changed in version 2.4.
echo $this->Html->css('Blog.common.css', array('plugin' => false));
Changed in version 2.1: The block
option was added.
Support for plugin syntax was added.
$type (string
) – The type meta tag you want.
$url (mixed
) – The URL for the meta tag, either a string or a
routing array.
$options (array
) – An array of html attributes.
This method is handy for linking to external resources like RSS/Atom feeds
and favicons. Like css(), you can specify whether or not you’d like this tag
to appear inline or appended to the meta
block by setting the ‘inline’
key in the $options parameter to false, ie - array('inline' => false)
.
If you set the “type” attribute using the $options parameter, CakePHP contains a few shortcuts:
type |
translated value |
---|---|
html |
text/html |
rss |
application/rss+xml |
atom |
application/atom+xml |
icon |
image/x-icon |
<?php
echo $this->Html->meta(
'favicon.ico',
'/favicon.ico',
array('type' => 'icon')
);
?>
// Output (line breaks added)
<link
href="http://example.com/favicon.ico"
title="favicon.ico" type="image/x-icon"
rel="alternate"
/>
<?php
echo $this->Html->meta(
'Comments',
'/comments/index.rss',
array('type' => 'rss')
);
?>
// Output (line breaks added)
<link
href="http://example.com/comments/index.rss"
title="Comments"
type="application/rss+xml"
rel="alternate"
/>
This method can also be used to add the meta keywords and descriptions. Example:
<?php
echo $this->Html->meta(
'keywords',
'enter any meta keyword here'
);
?>
// Output
<meta name="keywords" content="enter any meta keyword here" />
<?php
echo $this->Html->meta(
'description',
'enter any meta description here'
);
?>
// Output
<meta name="description" content="enter any meta description here" />
If you want to add a custom meta tag then the first parameter should be set to an array. To output a robots noindex tag use the following code:
echo $this->Html->meta(array('name' => 'robots', 'content' => 'noindex'));
Changed in version 2.1: The block
option was added.
$type (string
) – The type of doctype being made.
Returns a (X)HTML doctype tag. Supply the doctype according to the following table:
type |
translated value |
---|---|
html4-strict |
HTML4 Strict |
html4-trans |
HTML4 Transitional |
html4-frame |
HTML4 Frameset |
html5 |
HTML5 |
xhtml-strict |
XHTML1 Strict |
xhtml-trans |
XHTML1 Transitional |
xhtml-frame |
XHTML1 Frameset |
xhtml11 |
XHTML1.1 |
echo $this->Html->docType();
// Outputs:
// <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
// "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
echo $this->Html->docType('html5');
// Outputs: <!DOCTYPE html>
echo $this->Html->docType('html4-trans');
// Outputs:
// <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
// "http://www.w3.org/TR/html4/loose.dtd">
Changed in version 2.1: The default doctype is html5 in 2.1.
$data (array
) – A set of key => values with CSS properties.
$oneline (boolean
) – Should the contents be on one line.
Builds CSS style definitions based on the keys and values of the array passed to the method. Especially handy if your CSS file is dynamic.
echo $this->Html->style(array(
'background' => '#633',
'border-bottom' => '1px solid #000',
'padding' => '10px'
));
Will output:
background:#633; border-bottom:1px solid #000; padding:10px;
$path (string
) – Path to the image.
$options (array
) – An array of html attributes.
Creates a formatted image tag. The path supplied should be relative to /app/webroot/img/.
echo $this->Html->image('cake_logo.png', array('alt' => 'CakePHP'));
Will output:
<img src="/img/cake_logo.png" alt="CakePHP" />
To create an image link specify the link destination using the
url
option in $options
.
echo $this->Html->image("recipes/6.jpg", array(
"alt" => "Brownies",
'url' => array('controller' => 'recipes', 'action' => 'view', 6)
));
Will output:
<a href="/recipes/view/6">
<img src="/img/recipes/6.jpg" alt="Brownies" />
</a>
If you are creating images in emails, or want absolute paths to images you
can use the fullBase
option:
echo $this->Html->image("logo.png", array('fullBase' => true));
Will output:
<img src="http://example.com/img/logo.jpg" alt="" />
You can include image files from any loaded plugin using
plugin syntax. To include app/Plugin/DebugKit/webroot/img/icon.png
You could use the following:
echo $this->Html->image('DebugKit.icon.png');
If you want to include an image file which shares a name with a loaded
plugin you can do the following. For example if you had a Blog
plugin,
and also wanted to include app/webroot/img/Blog.icon.png
, you would:
echo $this->Html->image('Blog.icon.png', array('plugin' => false));
Changed in version 2.1: The fullBase
option was added.
Support for plugin syntax was added.
$title (string
) – The text to display as the body of the link.
$url (mixed
) – Either the string location, or a routing array.
$options (array
) – An array of html attributes.
General purpose method for creating HTML links. Use $options
to
specify attributes for the element and whether or not the
$title
should be escaped.
echo $this->Html->link(
'Enter',
'/pages/home',
array('class' => 'button', 'target' => '_blank')
);
Will output:
<a href="/pages/home" class="button" target="_blank">Enter</a>
Use 'full_base' => true
option for absolute URLs:
echo $this->Html->link(
'Dashboard',
array(
'controller' => 'dashboards',
'action' => 'index',
'full_base' => true
)
);
Will output:
<a href="http://www.yourdomain.com/dashboards/index">Dashboard</a>
Specify confirm
key in $options to display a JavaScript confirm()
dialog:
echo $this->Html->link(
'Delete',
array('controller' => 'recipes', 'action' => 'delete', 6),
array('confirm' => 'Are you sure you wish to delete this recipe?')
);
Will output:
<a href="/recipes/delete/6"
onclick="return confirm(
'Are you sure you wish to delete this recipe?'
);">
Delete
</a>
Query strings can also be created with link()
.
echo $this->Html->link('View image', array(
'controller' => 'images',
'action' => 'view',
1,
'?' => array('height' => 400, 'width' => 500))
);
Will output:
<a href="/images/view/1?height=400&width=500">View image</a>
When using named parameters, use the array syntax and include names for ALL parameters in the URL. Using the string syntax for paramters (i.e. “recipes/view/6/comments:false”) will result in the colon characters being HTML escaped and the link will not work as desired.
<?php
echo $this->Html->link(
$this->Html->image("recipes/6.jpg", array("alt" => "Brownies")),
array(
'controller' => 'recipes',
'action' => 'view',
'id' => 6,
'comments' => false
)
);
Will output:
<a href="/recipes/view/id:6/comments:false">
<img src="/img/recipes/6.jpg" alt="Brownies" />
</a>
HTML special characters in $title
will be converted to HTML
entities. To disable this conversion, set the escape option to
false in the $options
array.
<?php
echo $this->Html->link(
$this->Html->image("recipes/6.jpg", array("alt" => "Brownies")),
"recipes/view/6",
array('escape' => false)
);
Will output:
<a href="/recipes/view/6">
<img src="/img/recipes/6.jpg" alt="Brownies" />
</a>
Setting escape
to false will also disable escaping of attributes of the
link. As of 2.4 you can use the option escapeTitle
to disable just
escaping of title and not the attributes.
<?php
echo $this->Html->link(
$this->Html->image('recipes/6.jpg', array('alt' => 'Brownies')),
'recipes/view/6',
array('escapeTitle' => false, 'title' => 'hi "howdy"')
);
Will output:
<a href="/recipes/view/6" title="hi "howdy"">
<img src="/img/recipes/6.jpg" alt="Brownies" />
</a>
Changed in version 2.4: The escapeTitle
option was added.
Changed in version 2.6: The argument $confirmMessage
was deprecated. Use confirm
key
in $options
instead.
Also check HtmlHelper::url
method
for more examples of different types of URLs.
$path (string|array
) – Path to the media file, relative to the
webroot/{$options[‘pathPrefix’]} directory. Or an array where each
item itself can be a path string or an associate array containing keys
src and type.
$options (array
) – Array of HTML attributes, and special options.
Options:
type Type of media element to generate, valid values are “audio” or “video”. If type is not provided media type is guessed based on file’s mime type.
text Text to include inside the audio/video tag
pathPrefix Path prefix to use for relative URLs, defaults to ‘files/’
fullBase If set to true, the src attribute will get a full address including domain name
New in version 2.1.
Returns a formatted audio/video tag:
<?php echo $this->Html->media('audio.mp3'); ?>
// Output
<audio src="/files/audio.mp3"></audio>
<?php echo $this->Html->media('video.mp4', array(
'fullBase' => true,
'text' => 'Fallback text'
)); ?>
// Output
<video src="http://www.somehost.com/files/video.mp4">Fallback text</video>
<?php echo $this->Html->media(
array(
'video.mp4',
array(
'src' => 'video.ogg',
'type' => "video/ogg; codecs='theora, vorbis'"
)
),
array('autoplay')
); ?>
// Output
<video autoplay="autoplay">
<source src="/files/video.mp4" type="video/mp4"/>
<source src="/files/video.ogg" type="video/ogg;
codecs='theora, vorbis'"/>
</video>
$tag (string
) – The tag name being generated.
$text (string
) – The contents for the tag.
$options (array
) – An array of html attributes.
Returns text wrapped in a specified tag. If no text is specified then only the opening <tag> is returned.:
<?php
echo $this->Html->tag('span', 'Hello World.', array('class' => 'welcome'));
?>
// Output
<span class="welcome">Hello World</span>
// No text specified.
<?php
echo $this->Html->tag('span', null, array('class' => 'welcome'));
?>
// Output
<span class="welcome">
Note
Text is not escaped by default but you may use
$options['escape'] = true
to escape your text. This
replaces a fourth parameter boolean $escape = false
that was
available in previous versions.
$class (string
) – The class name for the div.
$text (string
) – The content inside the div.
$options (array
) – An array of html attributes.
Used for creating div-wrapped sections of markup. The first parameter specifies a CSS class, and the second is used to supply the text to be wrapped by div tags. If the ‘escape’ key has been set to true in the last parameter, $text will be printed HTML-escaped.
If no text is specified, only an opening div tag is returned.:
<?php
echo $this->Html->div('error', 'Please enter your credit card number.');
?>
// Output
<div class="error">Please enter your credit card number.</div>
$class (string
) – The class name for the paragraph.
$text (string
) – The content inside the paragraph.
$options (array
) – An array of html attributes.
Returns a text wrapped in a CSS-classed <p> tag. If no text is supplied, only a starting <p> tag is returned.:
<?php
echo $this->Html->para(null, 'Hello World.');
?>
// Output
<p>Hello World.</p>
$url (mixed
) – Either a string to a single JavaScript file, or an
array of strings for multiple files.
$options (array
) – An array of html attributes.
Include a script file(s), contained either locally or as a remote URL.
By default, script tags are added to the document inline. If you override
this by setting $options['inline']
to false, the script tags will instead
be added to the script
block which you can print elsewhere in the document.
If you wish to override which block name is used, you can do so by setting
$options['block']
.
$options['once']
controls whether or not you want to include this
script once per request or more than once. This defaults to true.
You can use $options to set additional properties to the generated script tag. If an array of script tags is used, the attributes will be applied to all of the generated script tags.
This method of JavaScript file inclusion assumes that the
JavaScript file specified resides inside the /app/webroot/js
directory:
echo $this->Html->script('scripts');
Will output:
<script type="text/javascript" href="/js/scripts.js"></script>
You can link to files with absolute paths as well to link files
that are not in app/webroot/js
:
echo $this->Html->script('/otherdir/script_file');
You can also link to a remote URL:
echo $this->Html->script('https://code.jquery.com/jquery.min.js');
Will output:
<script type="text/javascript" href="https://code.jquery.com/jquery.min.js">
</script>
The first parameter can be an array to include multiple files.
echo $this->Html->script(array('jquery', 'wysiwyg', 'scripts'));
Will output:
<script type="text/javascript" href="/js/jquery.js"></script>
<script type="text/javascript" href="/js/wysiwyg.js"></script>
<script type="text/javascript" href="/js/scripts.js"></script>
You can append the script tag to a specific block using the block
option:
echo $this->Html->script('wysiwyg', array('block' => 'scriptBottom'));
In your layout you can output all the script tags added to ‘scriptBottom’:
echo $this->fetch('scriptBottom');
You can include script files from any loaded plugin using
plugin syntax. To include
app/Plugin/DebugKit/webroot/js/toolbar.js
you could use the following:
echo $this->Html->script('DebugKit.toolbar.js');
If you want to include a script file which shares a name with a loaded
plugin you can do the following. For example if you had a Blog
plugin,
and also wanted to include app/webroot/js/Blog.plugins.js
, you would:
echo $this->Html->script('Blog.plugins.js', array('plugin' => false));
Changed in version 2.1: The block
option was added.
Support for plugin syntax was added.
$code (string
) – The code to go in the script tag.
$options (array
) – An array of html attributes.
Generate a code block containing $code
. Set $options['inline']
to
false to have the script block appear in the script
view block. Other
options defined will be added as attributes to script tags.
$this->Html->scriptBlock('stuff', array('defer' => true));
will
create a script tag with defer="defer"
attribute.
$options (array
) – An array of html attributes to be used when
scriptEnd is called.
Begin a buffering code block. This code block will capture all
output between scriptStart()
and scriptEnd()
and create an
script tag. Options are the same as scriptBlock()
End a buffering script block, returns the generated script element or null if the script block was opened with inline = false.
An example of using scriptStart()
and scriptEnd()
would
be:
$this->Html->scriptStart(array('inline' => false));
echo $this->Js->alert('I am in the javascript');
$this->Html->scriptEnd();
$list (array
) – Set of elements to list.
$options (array
) – Additional HTML attributes of the list (ol/ul) tag
or if ul/ol use that as tag.
$itemOptions (array
) – Additional HTML attributes of the list item (LI)
tag.
$tag (string
) – Type of list tag to use (ol/ul).
Build a nested list (UL/OL) out of an associative array:
$list = array(
'Languages' => array(
'English' => array(
'American',
'Canadian',
'British',
),
'Spanish',
'German',
)
);
echo $this->Html->nestedList($list);
Output:
// Output (minus the whitespace)
<ul>
<li>Languages
<ul>
<li>English
<ul>
<li>American</li>
<li>Canadian</li>
<li>British</li>
</ul>
</li>
<li>Spanish</li>
<li>German</li>
</ul>
</li>
</ul>
$names (array
) – An array of strings to create table headings.
$trOptions (array
) – An array of html attributes for the <tr>
$thOptions (array
) – An array of html attributes for the <th> elements
Creates a row of table header cells to be placed inside of <table> tags.
echo $this->Html->tableHeaders(array('Date', 'Title', 'Active'));
Output:
<tr>
<th>Date</th>
<th>Title</th>
<th>Active</th>
</tr>
echo $this->Html->tableHeaders(
array('Date','Title','Active'),
array('class' => 'status'),
array('class' => 'product_table')
);
Output:
<tr class="status">
<th class="product_table">Date</th>
<th class="product_table">Title</th>
<th class="product_table">Active</th>
</tr>
Changed in version 2.2: tableHeaders()
now accepts attributes per cell, see below.
As of 2.2 you can set attributes per column, these are used instead of the
defaults provided in the $thOptions
:
echo $this->Html->tableHeaders(array(
'id',
array('Name' => array('class' => 'highlight')),
array('Date' => array('class' => 'sortable'))
));
Output:
<tr>
<th>id</th>
<th class="highlight">Name</th>
<th class="sortable">Date</th>
</tr>
$data (array
) – A two dimensional array with data for the rows.
$oddTrOptions (array
) – An array of html attributes for the odd <tr>’s.
$evenTrOptions (array
) – An array of html attributes for the even <tr>’s.
$useCount (boolean
) – Adds class “column-$i”.
$continueOddEven (boolean
) – If false, will use a non-static $count variable,
so that the odd/even count is reset to zero just for that call.
Creates table cells, in rows, assigning <tr> attributes differently for odd- and even-numbered rows. Wrap a single table cell within an array() for specific <td>-attributes.
echo $this->Html->tableCells(array(
array('Jul 7th, 2007', 'Best Brownies', 'Yes'),
array('Jun 21st, 2007', 'Smart Cookies', 'Yes'),
array('Aug 1st, 2006', 'Anti-Java Cake', 'No'),
));
Output:
<tr><td>Jul 7th, 2007</td><td>Best Brownies</td><td>Yes</td></tr>
<tr><td>Jun 21st, 2007</td><td>Smart Cookies</td><td>Yes</td></tr>
<tr><td>Aug 1st, 2006</td><td>Anti-Java Cake</td><td>No</td></tr>
echo $this->Html->tableCells(array(
array(
'Jul 7th, 2007',
array(
'Best Brownies',
array('class' => 'highlight')
),
'Yes'),
array('Jun 21st, 2007', 'Smart Cookies', 'Yes'),
array(
'Aug 1st, 2006',
'Anti-Java Cake',
array('No', array('id' => 'special'))
),
));
Output:
<tr>
<td>

echo $this->Html->tableCells(
array(
array('Red', 'Apple'),
array('Orange', 'Orange'),
array('Yellow', 'Banana'),
),
array('class' => 'darker')
);
Output:
<tr class="darker"><td>Red</td><td>Apple</td></tr>

$url (mixed
) – A routing array.
$full (mixed
) – Either a boolean to indicate whether or not the base path should
be included or an array of options for Router::url()
Returns a URL pointing to a combination of controller and action. If $url is empty, it returns the REQUEST_URI, otherwise it generates the URL for the controller and action combo. If full is true, the full base URL will be prepended to the result:
echo $this->Html->url(array(
"controller" => "posts",
"action" => "view",
"bar"
));
// Output
/posts/view/bar
Here are a few more usage examples:
URL with named parameters:
echo $this->Html->url(array(
"controller" => "posts",
"action" => "view",
"foo" => "bar"
));
// Output
/posts/view/foo:bar
URL with extension:
echo $this->Html->url(array(
"controller" => "posts",
"action" => "list",
"ext" => "rss"
));
// Output
/posts/list.rss
URL (starting with ‘/’) with the full base URL prepended:
echo $this->Html->url('/posts', true);
// Output
http://somedomain.com/posts
URL with GET params and named anchor:
echo $this->Html->url(array(
"controller" => "posts",
"action" => "search",
"?" => array("foo" => "bar"),
"#" => "first"
));
// Output
/posts/search?foo=bar#first
For further information check Router::url in the API.
Returns a formatted existent block of $tag
:
$this->Html->useTag(
'form',
'http://example.com',
array('method' => 'post', 'class' => 'myform')
);
Output:
<form action="http://example.com" method="post" class="myform">
