Constructor & Destructor Documentation

◆ __construct()

grade_export_txt::__construct	(	$course,
		$groupid,
		$formdata )

Constructor should set up all the private variables ready to be pulled.

This constructor used to accept the individual parameters as separate arguments, in 2.8 this was simplified to just accept the data from the moodle form.

Parameters

object	$course
int	$groupid
stdClass \| null	$formdata

Note: Exporting as letters will lead to data loss if that exported set it re-imported.

Reimplemented from grade_export.

Member Function Documentation

◆ convert_flat_displaytypes_to_array()

static grade_export::convert_flat_displaytypes_to_array ( $displaytypes )

staticinherited

Convert the grade display types parameter into the required array to grade exporting class.

In order to export, the array key must be the display type name and the value must be the grade display type constant.

Note: Added support for combined display types constants like the (GRADE_DISPLAY_TYPE_PERCENTAGE_REAL) as the $CFG->grade_export_displaytype config is still used on 2.7 in case of missing displaytype url param. In these cases, the file will be exported with a column for each display type.

Parameters

string $displaytypes can be a single or multiple display type constants comma separated.

Return values

array\$types

◆ convert_flat_itemids_to_array()

static grade_export::convert_flat_itemids_to_array ( $itemids )

staticinherited

Parameters

string $itemids can be a single item id or many item ids comma separated.

Return values

array\$items correctly formatted array.
