Member Function Documentation

__call()

plugin_renderer_base::__call ( $method, $arguments )

inherited

Magic method used to pass calls otherwise meant for the standard renderer to it to ensure we don't go causing unnecessary grief.

Parameters

string	$method
array	$arguments

Return values

mixed

add_action_handler()

renderer_base::add_action_handler ( component_action $action, $id = null )

inherited

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

criterion_template()

gradingform_rubric_renderer::criterion_template	(		$mode,
			$options,
			$elementname = '{NAME}',
			$criterion = null,
			$levelsstr = '{LEVELS}',
			$value = null )

This function returns html code for displaying criterion.

Depending on $mode it may be the code to edit rubric, to preview the rubric, to evaluate somebody or to review the evaluation.

This function may be called from display_rubric() to display the whole rubric, or it can be called by itself to return a template used by JavaScript to add new empty criteria to the rubric being designed. In this case it will use macros like {NAME}, {LEVELS}, {CRITERION-id}, etc.

When overriding this function it is very important to remember that all elements of html form (in edit or evaluate mode) must have the name $elementname.

Also JavaScript relies on the class names of elements and when developer changes them script might stop working.

Parameters

int	$mode	rubric display mode, see gradingform_rubric_controller
array	$options	display options for this rubric, defaults are: gradingform_rubric_controller::get_default_options()
string	$elementname	the name of the form element (in editor mode) or the prefix for div ids (in view mode)
array | null	$criterion	criterion data
string	$levelsstr	evaluated templates for this criterion levels
array | null	$value	(only in view mode) teacher's feedback on this criterion

Return values

string

display_instance()

gradingform_rubric_renderer::display_instance	(	gradingform_rubric_instance	$instance,
			$idx,
			$cangrade )

Displays one grading instance.

Parameters

gradingform_rubric_instance	$instance
int	$idx	unique number of instance on page
bool	$cangrade	whether current user has capability to grade in this context

display_instances()

gradingform_rubric_renderer::display_instances	(		$instances,
			$defaultcontent,
			$cangrade )

Displays for the student the list of instances or default content if no instances found.

Parameters

array	$instances	array of objects of type gradingform_rubric_instance
string	$defaultcontent	default string that would be displayed without advanced grading
boolean	$cangrade	whether current user has capability to grade in this context

Return values

string

display_regrade_confirmation()

gradingform_rubric_renderer::display_regrade_confirmation	(		$elementname,
			$changelevel,
			$value )

Displays confirmation that students require re-grading.

Parameters

string	$elementname
int	$changelevel
string	$value

Return values

string

display_rubric()

gradingform_rubric_renderer::display_rubric	(		$criteria,
			$options,
			$mode,
			$elementname = null,
			$values = null )

This function returns html code for displaying rubric.

Depending on $mode it may be the code to edit rubric, to preview the rubric, to evaluate somebody or to review the evaluation.

It is very unlikely that this function needs to be overriden by theme. It does not produce any html code, it just prepares data about rubric design and evaluation, adds the CSS class to elements and calls the functions level_template, criterion_template and rubric_template

Parameters

array	$criteria	data about the rubric design
array	$options	display options for this rubric, defaults are: gradingform_rubric_controller::get_default_options()
int	$mode	rubric display mode, see gradingform_rubric_controller
string	$elementname	the name of the form element (in editor mode) or the prefix for div ids (in view mode)
array	$values	evaluation result

Return values

string
