Survey external functions.
|
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.
| 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. |
| array | containing keys for error (bool), exception and data. |
|
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.
| external_description | $description | description of the return values |
| mixed | $response | the actual response |
| mixed | response with added defaults for optional items, invalid_response_exception thrown if any problem found |
|
staticinherited |
Returns detailed function information.
| 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 |
| stdClass | description or false if not found or exception thrown |
| coding_exception | for any property and/or method that is missing or invalid |
|
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.
| array | $param |
| invalid_parameter_exception |
| context |
|
staticprotectedinherited |
Returns a prepared structure to use a context parameters.
| external_single_structure |
Reimplemented in core_competency\external, and tool_lp\external.
|
static |
Get the complete list of questions for the survey, including subquestions.
| int | $surveyid | the survey instance id |
| array | of warnings and the question list |
| moodle_exception |
|
static |
Returns description of method parameters.
| external_function_parameters |
|
static |
|
static |
Returns a list of surveys in a provided list of courses, if no list is provided all surveys that the user can view will be returned.
| array | $courseids | the course ids |
| array | of surveys details |
|
static |
Describes the parameters for get_surveys_by_courses.
| external_function_parameters |
|
static |

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.

| mixed | $params | the actual parameters |
| mixed | params with added defaults for optional items, invalid_parameters_exception thrown if any problem found |
