			$gpr,
			$context,
			$page = null

object	$gpr	grade plugin return tracking object
string	$context
int	$page	The current page being viewed (when report is paged)

Member Function Documentation

blank_hidden_total()

grade_report::blank_hidden_total (   $courseid,   $course_item,   $finalgrade  )

protected

Optionally blank out course/category totals if they contain any hidden items.

Deprecated:

since Moodle 2.8 - Call blank_hidden_total_and_adjust_bounds instead.

Parameters

string	$courseid	the course id
string	$course_item	an instance of grade_item
string	$finalgrade	the grade for the course_item

Return values

string

The new final grade

blank_hidden_total_and_adjust_bounds()

grade_report::blank_hidden_total_and_adjust_bounds (   $courseid,   $course_item,   $finalgrade  )

protected

Optionally blank out course/category totals if they contain any hidden items.

Parameters

string	$courseid	the course id
string	$course_item	an instance of grade_item
string	$finalgrade	the grade for the course_item

Return values

array[]

containing values for 'grade', 'grademax', 'grademin', 'aggregationstatus' and 'aggregationweight'

get_lang_string()

grade_report::get_lang_string	(		$strcode,
			$section = null
	)

First checks the cached language strings, then returns match if found, or uses get_string() to get it from the DB, caches it then returns it.

Parameters

string	$strcode
string	$section	Optional language section

Return values

string

get_numusers()

grade_report::get_numusers	(		$groups = true,
			$users = false
	)

Fetches and returns a count of all the users that will be shown on this page.

Parameters

boolean	$groups	include groups limit
boolean	$users	include users limit - default false, used for searching purposes

Return values

int	Count of users

get_pref()

grade_report::get_pref	(		$pref,
			$objectid = null
	)

Given the name of a user preference (without grade_report_ prefix), locally saves then returns the value of that preference.

If the preference has already been fetched before, the saved value is returned. If the preference is not set at the User level, the $CFG equivalent is given (site default). Can be called statically, but then doesn't benefit from caching

Parameters

string	$pref	The name of the preference (do not include the grade_report_ prefix)
int	$objectid	An optional itemid or categoryid to check for a more fine-grained preference

Return values

mixed

The value of the preference

get_sort_arrow()

grade_report::get_sort_arrow (   $direction = 'move',   $sortlink = null  )

protected

Returns an arrow icon inside an tag, for the purpose of sorting a column.

string	$direction
moodle_url	$sortlink

process_action()

grade_report::process_action (   $target,   $action  )

abstract

Processes a single action against a category, grade_item or grade.

Parameters

string	$target	Sortorder
string	$action	Which action to take (edit, delete etc...)

Return values

Reimplemented in grade_report_grader, grade_report_overview, gradereport_singleview, and grade_report_user.

process_data()

grade_report::process_data (   $data )

abstract

Handles form data sent by this report for this report.

Abstract method to implement in all children. @abstract

Parameters

array

$data

Return values

mixed

True or array of errors

set_pref()

grade_report::set_pref	(		$pref,
			$pref_value = 'default',
			$itemid = null
	)
