Class: calendar_event - X-Ref
Manage calendar events.This class provides the required functionality in order to manage calendar events.
It was introduced as part of Moodle 2.0 and was created in order to provide a
better framework for dealing with calendar events in particular regard to file
handling through the new file API.
| __construct($data = null) X-Ref |
| Instantiates a new event and optionally populates its properties with the data provided. param: \stdClass $data Optional. An object containing the properties to for |
| __set($key, $value) X-Ref |
| Magic set method. Attempts to call a set_$key method if one exists otherwise falls back to simply set the property. param: string $key property name param: mixed $value value of the property |
| __get($key) X-Ref |
| Magic get method. Attempts to call a get_$key method to return the property and ralls over to return the raw property. param: string $key property name return: mixed property value |
| __isset($key) X-Ref |
| Magic isset method. PHP needs an isset magic method if you use the get magic method and still want empty calls to work. param: string $key $key property name return: bool|mixed property value, false if property is not exist |
| calculate_context() X-Ref |
| Calculate the context value needed for an event. Event's type can be determine by the available value store in $data It is important to check for the existence of course/courseid to determine the course event. Default value is set to CONTEXT_USER return: \stdClass The context object. |
| get_context() X-Ref |
| Returns the context for this event. The context is calculated the first time is is requested and then stored in a member variable to be returned each subsequent time. This is a magical getter function that will be called when ever the context property is accessed, e.g. $event->context. return: context |
| get_editoroptions() X-Ref |
| Returns an array of editoroptions for this event. return: array event editor options |
| get_description() X-Ref |

| update($data, $checkcapability=true) X-Ref |
| Update or create an event within the database Pass in a object containing the event properties and this function will insert it into the database and deal with any associated files Capability checking should be performed if the user is directly manipulating the event and no other capability has been tested. However if the event is not being manipulated directly by the user and another capability has been checked for them to do this then capabilites should not be checked. For example if a user is editing an event in the calendar the check should be true, but if you are updating an event in an activities settings are changed then the calendar capabilites should not be checked. param: \stdClass $data object of event param: bool $checkcapability If Moodle should check the user can manage the calendar events for this call or not. return: bool event updated |

| Deletes an event and if selected an repeated events in the same series This function deletes an event, any associated events if $deleterepeated=true, and cleans up any files associated with the events. param: bool $deleterepeated delete event repeatedly return: bool succession of deleting event |
| properties($prepareeditor = false) X-Ref |
| Fetch all event properties. This function returns all of the events properties as an object and optionally can prepare an editor for the description field at the same time. This is designed to work when the properties are going to be used to set the default values of a moodle forms form. param: bool $prepareeditor If set to true a editor is prepared for use with return: \stdClass Object containing event properties |
| toggle_visibility($force = null) X-Ref |
| Toggles the visibility of an event param: null|bool $force If it is left null the events visibility is flipped, return: bool if event is successfully updated, toggle will be visible |
| load($param) X-Ref |
| Returns an event object when provided with an event id. This function makes use of MUST_EXIST, if the event id passed in is invalid it will result in an exception being thrown. param: int|object $param event object or event id return: calendar_event |
| create($properties, $checkcapability = true) X-Ref |
| Creates a new event and returns an event object. Capability checking should be performed if the user is directly creating the event and no other capability has been tested. However if the event is not being created directly by the user and another capability has been checked for them to do this then capabilites should not be checked. For example if a user is creating an event in the calendar the check should be true, but if you are creating an event in an activity when it is created then the calendar capabilites should not be checked. param: \stdClass|array $properties An object containing event properties param: bool $checkcapability If Moodle should check the user can manage the calendar events for this call or not. return: calendar_event|bool The event object or false if it failed |
| format_external_name() X-Ref |
| Format the event name using the external API. This function should we used when text formatting is required in external functions. return: string Formatted name. |
