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_entries()

static core_blog\external::get_entries	(	$filters = `array()`,
		$page = `0`,
		$perpage = `10`
	)

static

Return blog entries.

Parameters

array	$filters	the parameters to filter the blog listing
int	$page	the blog page to return
int	$perpage	the number of posts to return per page

Return values

array with the blog entries and warnings

Since: Moodle 3.6

◆ get_entries_parameters()

static core_blog\external::get_entries_parameters ( )

static

Returns description of get_entries() parameters.

Return values

external_function_parameters

Since: Moodle 3.6

◆ get_entries_returns()

static core_blog\external::get_entries_returns ( )

static

Returns description of get_entries() result value.

Return values

external_description

Since: Moodle 3.6

◆ 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_access_and_filters()

static core_blog\external::validate_access_and_filters ( $rawwsfilters )

staticprotected

Validate access to the blog and the filters to apply when listing entries.

Parameters

array $rawwsfilters array containing the filters in WS format

Return values

array context, filters to apply and the calculated courseid and user

Since: Moodle 3.6

◆ 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

◆ view_entries()

static core_blog\external::view_entries ( $filters = array() )

static

Trigger the blog_entries_viewed event.

Parameters

array $filters the parameters used in the filter of get_entries

Return values

array with status result and warnings

Since: Moodle 3.6

◆ view_entries_parameters()

static core_blog\external::view_entries_parameters ( )

static

Returns description of view_entries() parameters.

Return values

external_function_parameters

Since: Moodle 3.6

◆ view_entries_returns()

static core_blog\external::view_entries_returns ( )

static

Returns description of view_entries() result value.

Return values

external_description

Since: Moodle 3.6
