Detailed Description

Multianswer (aka embedded, cloze) question type conversion handler.

Member Function Documentation

◆ get_component_name()

moodle1_plugin_handler::get_component_name ( )

inherited

Returns the normalized name of the plugin, eg mod_workshop.

Return values

string

◆ get_converter()

moodle1_handler::get_converter ( )

inherited

Return values

moodle1_converter the converter that required this handler

◆ get_default_numerical_options()

moodle1_qtype_handler::get_default_numerical_options	(	$oldquestiontextformat,
		$units
	)

protectedinherited

Returns default numerical_option structure.

This structure is not present in moodle.xml, we create a new artificial one here.

See also: write_numerical_options()

Parameters

int $oldquestiontextformat

Return values

array

◆ get_paths()

moodle1_qtype_handler::get_paths ( )

finalinherited

See also: self::get_question_subpaths()

◆ get_question_subpaths()

moodle1_qtype_multianswer_handler::get_question_subpaths ( )

Return values

array

Reimplemented from moodle1_qtype_handler.

◆ has_xml_writer()

moodle1_xml_handler::has_xml_writer ( )

protectedinherited

Checks if the XML writer has been opened by self::open_xml_writer().

Return values

bool

◆ make_sure_xml_exists()

moodle1_xml_handler::make_sure_xml_exists	(	$filename,
		$rootelement = `false`,
		$content = `array()`
	)

protectedinherited

Makes sure that a new XML file exists, or creates it itself.

This is here so we can check that all XML files that the restore process relies on have been created by an executed handler. If the file is not found, this method can create it using the given $rootelement as an empty root container in the file.

Parameters

string	$filename	relative file name like 'course/course.xml'
string \| bool	$rootelement	root element to use, false to not create the file
array	$content	content of the root element

Return values

bool	true is the file existed, false if it did not

◆ migrate_files()

moodle1_qtype_handler::migrate_files	(	$text,
		$component,
		$filearea,
		$itemid
	)

protectedinherited

Migrate files belonging to one qtype plugin text field.

Parameters

array	$text	the html fragment containing references to files
string	$component	the component for restored files
string	$filearea	the file area for restored files
int	$itemid	the itemid for restored files

Return values

string the text for this field, after files references have been processed

◆ process_question()

moodle1_qtype_multianswer_handler::process_question	(	array	$data,
		array	$raw
	)

Appends the multianswer specific information to the question.

Note that there is an upgrade step 2008050800 that is not replayed here as I suppose there was an error on restore and the backup file contains correct data. If I'm wrong on this assumption then the parent of the embedded questions could be fixed on conversion in theory (by using a temporary stash that keeps multianswer's id and its sequence) but the category fix would be tricky in XML.

Reimplemented from moodle1_qtype_handler.

◆ use_xml_writer()

moodle1_qtype_handler::use_xml_writer ( xml_writer $xmlwriter )

inherited

Provides a xml_writer instance to this qtype converter.

Parameters

xml_writer $xmlwriter

◆ write_answers()

moodle1_qtype_handler::write_answers	(	array	$answers,
			$qtype
	)

protectedinherited

Converts the answers and writes them into the questions.xml.

The structure "answers" is used by several qtypes. It contains data from {question_answers} table.

Parameters

array	$answers	as parsed by the grouped parser in moodle.xml
string	$qtype	containing the answers

◆ write_dataset_definitions()

moodle1_qtype_handler::write_dataset_definitions ( array $datasetdefinitions )

protectedinherited

Writes the dataset_definitions structure.

Parameters

array $datasetdefinitions array of dataset_definition structures

◆ write_numerical_options()

moodle1_qtype_handler::write_numerical_options ( array $numericaloption )

protectedinherited

Writes the numerical_options structure.

See also: get_default_numerical_options()

Parameters

array $numericaloption

◆ write_numerical_units()

moodle1_qtype_handler::write_numerical_units ( array $numericalunits )

protectedinherited

Writes the grouped numerical_units structure.

Parameters

array $numericalunits

◆ write_xml()

moodle1_xml_handler::write_xml	(		$element,
		array	$data,
		array	$attribs = `array()`,
			$parent = `'/'`
	)

protectedinherited

Writes the given XML tree data into the currently opened file.

Parameters

string	$element	the name of the root element of the tree
array	$data	the associative array of data to write
array	$attribs	list of additional fields written as attributes instead of nested elements
string	$parent	used internally during the recursion, do not set yourself
