__call()

plugin_renderer_base::__call ( $method, $arguments )

Adds a JS action for the element with the provided id.

This method adds a JS event for the provided component action to the page and then returns the id that the event has been attached to. If no id has been provided then a new ID is generated by html_writer::random_id()

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 )

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.

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')

render_registration_view()

enrol_lti\output\renderer::render_registration_view	(	int	$registrationid,
		string	$activetab = '' )

Renders the registration view page, allowing admins to view tool details, platform details and deployments.

The template uses dynamic tabs, which renders with one active tab and uses js to change tabs if desired. E.g. if an anchor link is used to go to another tab, the page will first load the active tab, then switch to the tab referenced in the anchor using JS. To allow navigation to the page with a specific tab selected, and WITHOUT the js slowdown, this renderer method allows callers to specify which tab is set as the active tab during first render. Valid values correspond to the tab names in the enrol_lti/local/ltiadvantage/registration_view template, currently:

• 'tooldetails' - to render with the Tool details tab as the active tab
• 'platformdetails' - to render with the Platform details tab as the active tab
• 'tooldeployments' - to render with the Tool deployments tab as the active tab By default, the platformdetails tab will be selected as active.

Parameters

int	$registrationid	the id of the registration to display information for.
string	$activetab	a string identifying the tab to preselect when rendering.

Return values

bool|string
