Parameters

component_action	$action
string	$id

Return values

string id of element, either original submitted or random new if not supplied

◆ get_compact_logo_url()

renderer_base::get_compact_logo_url	(	$maxwidth = `300`,
		$maxheight = `300`
	)

inherited

Return the site's compact logo URL, if any.

Parameters

int	$maxwidth	The maximum width, or null when the maximum width does not matter.
int	$maxheight	The maximum height, or null when the maximum height does not matter.

Return values

moodle_url|false

◆ get_logo_url()

renderer_base::get_logo_url	(	$maxwidth = `null`,
		$maxheight = `200`
	)

inherited

Return the site's logo URL, if any.

Parameters

int	$maxwidth	The maximum width, or null when the maximum width does not matter.
int	$maxheight	The maximum height, or null when the maximum height does not matter.

Return an instance of the mustache class.

Since: 2.9

Return values

Mustache_Engine

◆ h5p_alter_filtered_parameters()

This is useful for adapting the content to the current context.

Parameters

array \| object	$parameters	The content parameters for the library
string	$name	The machine readable name of the library
int	$majorversion	Major version of the library
int	$minorversion	Minor version of the library

Alter semantics before they are processed.

This is useful for changing how the editor looks and how content parameters are filtered.

Parameters

object \| object	$semantics	Semantics as object
string	$name	Machine name of library
int	$majorversion	Major version of library
int	$minorversion	Minor version of library

◆ h5p_alter_styles()

core_h5p\output\renderer::h5p_alter_styles	(	&	$scripts,
		array	$libraries,

Parameters

array \| object	$scripts	List of stylesheets that will be loaded
array	$libraries	Array of libraries indexed by the library's machineName
string	$embedtype	Possible values: div, iframe, external, editor

◆ has_started()

renderer_base::has_started ( )

inherited

Returns true is output has already started, and false if not.

boolean true if the header has been printed.

◆ image_url()

renderer_base::image_url	(	$imagename,

The exact image location and extension is determined automatically by searching for gif|png|jpg|jpeg, please note there can not be diferent images with the different extension. The imagename is for historical reasons a relative path name, it may be changed later for core images. It is recommended to not use subdirectories in plugin and theme pix directories.

There are three types of images: 1/ theme images - stored in theme/mytheme/pix/, use component 'theme' 2/ core images - stored in /pix/, overridden via theme/mytheme/pix_core/ 3/ plugin images - stored in mod/mymodule/pix, overridden via theme/mytheme/pix_plugins/mod/mymodule/, example: image_url('comment', 'mod_glossary')

Parameters

string	$imagename	the pathname of the image
string	$component	full plugin name (aka component) or 'theme'

moodle_url
