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$functionA webservice function name.
array$argsParams array (named params)
boolean$ajaxonlyIf true, an extra check will be peformed to see if ajax is required.
Return values
arraycontaining 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$descriptiondescription of the return values
mixed$responsethe actual response
Return values
mixedresponse 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$functionname of external function or record from external_function
int$strictnessIGNORE_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
stdClassdescription 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_course_blocks()

static core_block_external::get_course_blocks (   $courseid,
  $returncontents = false 
)
static

Returns blocks information for a course.

Parameters

bool$returncontentsWhether to return the block contents
Return values
arrayBlocks list and possible warnings
Exceptions

static

Returns description of get_course_blocks parameters.

Return values
external_function_parameters
Since

◆ get_dashboard_blocks()

static core_block_external::get_dashboard_blocks (   $userid = 0,
  $returncontents = false 
)

◆ validate_parameters()

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