Detailed Description

This class is a collection of static functions that serve two purposes:

1) Implement any algorithms specified by HTML5, or other HTML specifications, in a convenient and self-contained way.

2) Allow HTML elements to be conveniently and safely generated, like the current Xml class but a) less confused (Xml supports HTML-specific things, but only sometimes!) and b) not necessarily confined to XML-compatible output.

There are two important configuration options this class uses:

$wgMimeType: If this is set to an xml MIME type then output should be valid XHTML5.

This class is meant to be confined to utility functions that are called from trusted code paths. It does not do enforcement of policy like not allowing elements.

◆ buttonAttributes()

static Html::buttonAttributes	(	array	$attrs,
		array	$modifiers = `[]`
	)

static

Modifies a set of attributes meant for button elements and apply a set of default attributes when $wgUseMediaWikiUIEverywhere enabled.

Parameters

array	$attrs	HTML attributes in an associative array
string[]	$modifiers	classes to add to the button

See also: https://tools.wmflabs.org/styleguide/desktop/index.html for guidance on available modifiers

Returns: array Modified attributes array

Definition at line 111 of file Html.php.

References $wgUseMediaWikiUIEverywhere.

◆ check()

static Html::check	(		$name,
			$checked = `false`,
		array	$attribs = `[]`
	)

static

Convenience function to produce a checkbox (input element with type=checkbox)

Parameters

string	$name	Name attribute
bool	$checked	Whether the checkbox is checked or not
array	$attribs	Array of additional attributes

Returns: string Raw HTML

Definition at line 717 of file Html.php.

◆ closeElement()

static Html::closeElement ( $element )

static

Returns "</$element>".

Since: 1.17

Parameters

string $element Name of the element, e.g., 'a'

Returns: string A closing tag

Definition at line 316 of file Html.php.

◆ dropDefaults()

static Html::dropDefaults	(		$element,
		array	$attribs
	)

staticprivate

Given an element name and an associative array of element attributes, return an array that is functionally identical to the input array, but possibly smaller.

In particular, attributes might be stripped if they are given their default values.

This method is not guaranteed to remove all redundant attributes, only some common ones and some others selected arbitrarily at random. It only guarantees that the output array should be functionally identical to the input array (currently per the HTML 5 draft as of 2009-09-06).

Parameters

string	$element	Name of the element, e.g., 'a'
array	$attribs	Associative array of attributes, e.g., [ 'href' => 'https://www.mediawiki.org/' ]. See expandAttributes() for further documentation.

Returns: array An array of attributes functionally identical to $attribs

Definition at line 339 of file Html.php.

References $type.

◆ element()

static Html::element	(	$element,
		$attribs = `[]`,
		$contents = `''`
	)

static

Identical to rawElement(), but HTML-escapes $contents (like Xml::element()).

Parameters

string	$element	Name of the element, e.g., 'a'
array	$attribs	Associative array of attributes, e.g., [ 'href' => 'https://www.mediawiki.org/' ]. See expandAttributes() for further documentation.
string	$contents

Returns: string

Definition at line 232 of file Html.php.

◆ errorBox()

static Html::errorBox	(	$html,
		$heading = `''`,
		$className = `''`
	)

static

Return an error box.

Since: 1.31; 1.34 $className optional parameter added

Parameters

string	$html	of contents of error box
string	$heading	(optional)
string	$className	(optional) corresponding to box

Returns: string of HTML representing an error box.

Definition at line 768 of file Html.php.

◆ expandAttributes()

static Html::expandAttributes ( array $attribs )

static

Given an associative array of element attributes, generate a string to stick after the element name in HTML output.

Like [ 'href' => 'https://www.mediawiki.org/' ] becomes something like ' href="https://www.mediawiki.org"'. Again, this is like Xml::expandAttributes(), but it implements some HTML-specific logic.

Attributes that can contain space-separated lists ('class', 'accesskey' and 'rel') array values are allowed as well, which will automagically be normalized and converted to a space-separated string. In addition to a numerical array, the attribute value may also be an associative array. See the example below for how that works.

Numerical array: Html::element( 'em', [

'class' => [ 'foo', 'bar' ]

] );

// gives '<em class="foo bar"></em>'

Html\element
static element( $element, $attribs=[], $contents='')
Identical to rawElement(), but HTML-escapes $contents (like Xml::element()).
Definition Html.php:232

Associative array: Html::element( 'em', [

'class' => [ 'foo', 'bar', 'foo' => false, 'quux' => true ]

] );

// gives '<em class="bar quux"></em>'

Parameters

array $attribs Associative array of attributes, e.g., [ 'href' => 'https://www.mediawiki.org/' ]. Values will be HTML-escaped. A value of false or null means to omit the attribute. For boolean attributes, you can omit the key, e.g., [ 'checked' ] instead of [ 'checked' => 'checked' ] or such.

Exceptions

MWException If an attribute that doesn't allow lists is set to an array

Returns: string HTML fragment that goes between element name and '>' (starting with a space if at least one attribute is output)

Definition at line 476 of file Html.php.

◆ getTextInputAttributes()

static Html::getTextInputAttributes ( array $attrs )

static

Modifies a set of attributes meant for text input elements and apply a set of default attributes.

Removes size attribute when $wgUseMediaWikiUIEverywhere enabled.

Definition at line 138 of file Html.php.

Returns: string Raw HTML

Definition at line 994 of file Html.php.

References $wgHtml5Version, $wgMimeType, and $wgXhtmlNamespaces.

◆ inlineScript()

static Html::inlineScript	(	$contents,
		$nonce = `null`
	)

static

Output an HTML script tag with the given contents.

It is unsupported for the contents to contain the sequence <script or </script (case-insensitive). This ensures the script can be terminated easily and consistently. It is the responsibility of the caller to avoid such character sequence by escaping or avoiding it. If found at run-time, the contents are replaced with a comment, and a warning is logged server-side.

Parameters

string	$contents	JavaScript
string \| null	$nonce	Nonce for CSP header, from OutputPage->getCSP()->getNonce()

Returns: string Raw HTML

Definition at line 589 of file Html.php.

References ContentSecurityPolicy\isNonceRequired(), wfLogWarning(), and wfWarn().

◆ inlineStyle()

static Html::inlineStyle	(	$contents,
		$media = `'all'`,
		$attribs = `[]`
	)

static

Output a "<style>" tag with the given contents for the given media type (if any).

References $lang, $wgLang, NS_MAIN, and wfMessage().

◆ openElement()

static Html::openElement	(	$element,
		$attribs = `[]`

References wfWarn().

◆ radio()

static Html::radio	(		$name,

static

Convenience function to produce a radio button (input element with type=radio)

Parameters

string	$name	Name attribute
bool	$checked	Whether the radio button is checked or not
array	$attribs	Array of additional attributes

Returns: string Raw HTML

Definition at line 792 of file Html.php.

◆ rawElement()

static Html::rawElement	(	$element,
		$attribs = `[]`,

static

Returns an HTML element in a string.

The major advantage here over manually typing out the HTML is that it will escape all attribute values.

This is quite similar to Xml::tags(), but it implements some useful HTML-specific logic. For instance, there is no $allowShortTag parameter: the closing tag is magically omitted if $element has an empty content model.

Parameters

string	$element	The element's name, e.g., 'a'
array	$attribs	Associative array of attributes, e.g., [ 'href' => 'https://www.mediawiki.org/' ]. See expandAttributes() for further documentation.
string	$contents	The raw HTML contents of the element: not escaped!

Returns: string Raw HTML

Definition at line 210 of file Html.php.

◆ srcSet()

Generates a srcset attribute value from an array mapping pixel densities to URLs. A trailing 'x' in pixel density values is optional.

Note: srcset width and height values are not supported.

See also: https://html.spec.whatwg.org/#attr-img-srcset

Example:: Html::srcSet( [

'1x' => 'standard.jpeg',

'1.5x' => 'large.jpeg',

'3x' => 'extra-large.jpeg',

] );

// gives 'standard.jpeg 1x, large.jpeg 1.5x, extra-large.jpeg 2x'
