Question 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 |
Gets the list of random questions for the given criteria.
The questions will be exported in a summaries format and won't include all of the question data.
| int | $categoryid | Category id to find random questions |
| bool | $includesubcategories | Include the subcategories in the search |
| int[] | $tagids | Only include questions with these tags |
| int | $contextid | The context id where the questions will be rendered |
| int | $limit | Maximum number of results to return |
| int | $offset | Number of items to skip from the beginning of the result set. |
| array | The list of questions and total question count. |
|
static |
Returns description of method parameters.
| external_function_parameters. |
|
staticinherited |
Set context restriction for all following subsequent function calls.
| stdClass | $context | the context restriction |
|

This method has to be called before every operation that takes a longer time to finish!
| int | $seconds | max expected time the next operation needs |
|
static |
Handles the tags form submission.
| int | $questionid | The question id. |
| int | $contextid | The editing context id. |
| string | $formdata | The question tag form data in a URI encoded param string |
| array | The created or modified question tag |

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