Member Function Documentation

◆ add_rating()

static core_rating_external::add_rating	(	$contextlevel,
		$instanceid,
		$component,
		$ratingarea,
		$itemid,
		$scaleid,
		$rating,
		$rateduserid,
		$aggregation = `RATING_AGGREGATE_NONE`
	)

static

Adds a rating to an item.

Parameters

string	$contextlevel	course, module, user...
int	$instanceid	the instance if for the context element
string	$component	the name of the component
string	$ratingarea	rating area
int	$itemid	the item id
int	$scaleid	the scale id
int	$rating	the user rating
int	$rateduserid	the rated user id
int	$aggregation	the aggregation method

Return values

array result and possible warnings

Exceptions

moodle_exception

Since: Moodle 3.2

◆ add_rating_parameters()

static core_rating_external::add_rating_parameters ( )

static

Returns description of add_rating parameters.

Return values

external_function_parameters

Since: Moodle 3.2

◆ add_rating_returns()

static core_rating_external::add_rating_returns ( )

static

Returns description of add_rating result values.

Return values

external_single_structure

Since: Moodle 3.2

◆ call_external_function()

static external_api::call_external_function	(	$function,
		$args,
		$ajaxonly = `false`
	)

staticinherited

Call an external function validating all params/returns correctly.

Note that an external function may modify the state of the current page, so this wrapper saves and restores tha PAGE and COURSE global variables before/after calling the external function.

Parameters

string	$function	A webservice function name.
array	$args	Params array (named params)
boolean	$ajaxonly	If true, an extra check will be peformed to see if ajax is required.

Return values

array containing keys for error (bool), exception and data.

◆ clean_returnvalue()

static external_api::clean_returnvalue	(	external_description	$description,
			$response
	)

staticinherited

Clean response If a response attribute is unknown from the description, we just ignore the attribute.

If a response attribute is incorrect, invalid_response_exception is thrown. Note: this function is similar to validate parameters, however it is distinct because parameters validation must be distinct from cleaning return values.

Parameters

external_description	$description	description of the return values
mixed	$response	the actual response

Return values

mixed response with added defaults for optional items, invalid_response_exception thrown if any problem found

◆ external_function_info()

static external_api::external_function_info	(	$function,
		$strictness = `MUST_EXIST`
	)

staticinherited

Returns detailed function information.

Parameters

string \| object	$function	name of external function or record from external_function
int	$strictness	IGNORE_MISSING means compatible mode, false returned if record not found, debug message if more found; MUST_EXIST means throw exception if no record or multiple records found

Return values

stdClass description or false if not found or exception thrown

Since: Moodle 2.0

◆ get_context_from_params()

static external_api::get_context_from_params ( $param )

staticprotectedinherited

Get context from passed parameters.

The passed array must either contain a contextid or a combination of context level and instance id to fetch the context. For example, the context level can be "course" and instanceid can be courseid.

See context_helper::get_all_levels() for a list of valid context levels.

Parameters

array $param

Since: Moodle 2.6

Exceptions

invalid_parameter_exception

Return values

context

◆ get_context_parameters()

static external_api::get_context_parameters ( )

staticprotectedinherited

Returns a prepared structure to use a context parameters.

Return values

external_single_structure

Reimplemented in tool_lp\external, and core_competency\external.

◆ get_item_ratings()

static core_rating_external::get_item_ratings	(	$contextlevel,
		$instanceid,
		$component,
		$ratingarea,
		$itemid,
		$scaleid,
		$sort
	)

static

Retrieve a list of ratings for a given item (forum post etc)

Parameters

string	$contextlevel	course, module, user...
int	$instanceid	the instance if for the context element
string	$component	the name of the component
string	$ratingarea	rating area
int	$itemid	the item id
int	$scaleid	the scale id
string	$sort	sql order (firstname, rating or timemodified)

Return values

array Result and possible warnings

Exceptions

moodle_exception

Since: Moodle 2.9

static core_rating_external::get_item_ratings_parameters ( )

static

Returns description of get_item_ratings parameters.

Return values

external_function_parameters

Since: Moodle 2.9

◆ get_item_ratings_returns()

static core_rating_external::get_item_ratings_returns ( )

static

Returns description of get_item_ratings result values.

Return values

external_single_structure

Since: Moodle 2.9

◆ set_context_restriction()

static external_api::set_context_restriction ( $context )

staticinherited

Set context restriction for all following subsequent function calls.

Parameters

stdClass $context the context restriction

Since: Moodle 2.0

◆ set_timeout()

static external_api::set_timeout ( $seconds = 360 )

staticinherited

This method has to be called before every operation that takes a longer time to finish!

Parameters

int $seconds max expected time the next operation needs

Since: Moodle 2.0

◆ validate_context()

static external_api::validate_context ( $context )

staticinherited

Makes sure user may execute functions in this context.

Parameters

Since: Moodle 2.0

◆ validate_parameters()

static external_api::validate_parameters	(	external_description	$description,
			$params
	)

staticinherited
