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
