Member Function Documentation

◆ 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

Author: 2010 Jerome Mouneyrac

Since: Moodle 2.0

◆ 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 core_competency\external, and tool_lp\external.

◆ get_trusted_h5p_file()

static core_h5p\external::get_trusted_h5p_file	(	string	$url,
		int	$frame,
		int	$export,
		int	$embed,
		int	$copyright
	)

static

Return the H5P file trusted.

The Mobile App needs to work with an H5P package which can trust. And this H5P package is only trusted by the Mobile App once it's been processed by the core checking the right caps, validating the H5P package and doing any clean-up process involved.

Since: Moodle 3.8

Parameters

string	$url	H5P file url
int	$frame	The frame allow to show the bar options below the content
int	$export	The export allow to download the package
int	$embed	The embed allow to copy the code to your site
int	$copyright	The copyright option

Return values

array

Exceptions

moodle_exception

◆ get_trusted_h5p_file_parameters()

static core_h5p\external::get_trusted_h5p_file_parameters ( )

static

get_trusted_h5p_file parameters.

Since: Moodle 3.8

Return values

external_function_parameters

◆ get_trusted_h5p_file_returns()

static core_h5p\external::get_trusted_h5p_file_returns ( )

static

get_trusted_h5p_file return

Since: Moodle 3.8

Return values

external_description

◆ 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

stdClass $context

Since: Moodle 2.0

◆ validate_parameters()

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

staticinherited

Validates submitted function parameters, if anything is incorrect invalid_parameter_exception is thrown.

This is a simple recursive method which is intended to be called from each implementation method of external API.

Parameters

external_description	$description	description of parameters
mixed	$params	the actual parameters

Return values

mixed params with added defaults for optional items, invalid_parameters_exception thrown if any problem found

Since: Moodle 2.0
