assign_grouping()

static core_group_external::assign_grouping ( $assignments )

static

Assign a group to a grouping.

Parameters

array

$assignments

of arrays with keys groupid, groupingid

Return values

void

Since

Moodle 2.3

Return values

null

Since

Moodle 2.3

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
