Member Function Documentation

◆ __get()

core\event\base::__get ( $name )

inherited

Magic getter for read only access.

Parameters

string $name

Return values

mixed

◆ __isset()

core\event\base::__isset ( $name )

inherited

Is data property set?

Parameters

string $name

Return values

bool

◆ __set()

core\event\base::__set	(		$name,
			$value )

inherited

Magic setter.

Note: we must not allow modification of data from outside, after trigger() the data MUST NOT CHANGE!!!

Parameters

string	$name
mixed	$value

Exceptions

coding_exception

◆ add_record_snapshot()

core\event\base::add_record_snapshot	(		$tablename,
			$record )

finalinherited

Add cached data that will be most probably used in event observers.

This is used to improve performance, but it is required for data that was just deleted.

Parameters

string	$tablename
stdClass	$record

Exceptions

coding_exception if used after trigger()

◆ can_view()

core\event\base::can_view ( $user_or_id = null )

inherited

This method was originally intended for granular access control on the event level, unfortunately the proper implementation would be too expensive in many cases.

Deprecated: since 2.7

Parameters

int | stdClass $user_or_id ID of the user.

Return values

bool	True if the user can view the event, false otherwise.

Reimplemented in mod_feedback\event\response_deleted, and mod_feedback\event\response_submitted.

◆ create()

static core\event\base::create ( array $data = null )

staticfinalinherited

Create new event.

The optional data keys as: 1/ objectid - the id of the object specified in class name 2/ context - the context of this event 3/ other - the other data describing the event, can not contain objects 4/ relateduserid - the id of user which is somehow related to this event

Parameters

array $data

Return values

core\event\base returns instance of new event

Exceptions

coding_exception

◆ get_context()

core\event\base::get_context ( )

inherited

Returns event context.

Return values

context

◆ get_data()

core\event\base::get_data ( )

inherited

Return standardised event data as array.

Return values

array All elements are scalars except the 'other' field which is array.

◆ get_description()

core\event\course_module_viewed::get_description ( )

inherited

Returns description of what happened.

Return values

string

Reimplemented from core\event\base.

◆ get_explanation()

static core\event\base::get_explanation ( )

staticinherited

Get an explanation of what the class does.

By default returns the phpdocs from the child event class. Ideally this should be overridden to return a translatable get_string style markdown. e.g. return new lang_string('eventyourspecialevent', 'plugin_type');

Return values

string An explanation of the event formatted in markdown style.

◆ get_logextra()

core\event\base::get_logextra ( )

inherited

Return auxiliary data that was stored in logs.

List of standard properties:

origin: IP number, cli,cron
realuserid: id of the user when logged-in-as

Return values

array the format is standardised by logging API

◆ get_name()

static core\event\course_module_viewed::get_name ( )

staticinherited

Return localised event name.

Return values

string

Reimplemented from core\event\base.

◆ get_name_with_info()

static core\event\base::get_name_with_info ( )

staticinherited

Returns the event name complete with metadata information.

This includes information about whether the event has been deprecated so should not be used in all situations - for example within reports themselves.

If overriding this function, please ensure that you call the parent version too.

Return values

string

◆ get_objectid_mapping()

static mod_chat\event\course_module_viewed::get_objectid_mapping ( )

static

This is used when restoring course logs where it is required that we map the objectid to it's new value in the new course.

Does nothing in the base class except display a debugging message warning the user that the event does not contain the required functionality to map this information. For events that do not store an objectid this won't be called, so no debugging message will be displayed.

Example of usage:

return array('db' => 'assign_submissions', 'restore' => 'submission');

If the objectid can not be mapped during restore set the value to core\event\base\NOT_MAPPED, example -

return array('db' => 'some_table', 'restore' => core\event\base\NOT_MAPPED);

Note - it isn't necessary to specify the 'db' and 'restore' values in this case, so you can also use -

return core\event\base\NOT_MAPPED;

The 'db' key refers to the database table and the 'restore' key refers to the name of the restore element the objectid is associated with. In many cases these will be the same.

Return values

string the name of the restore mapping the objectid links to

Reimplemented from core\event\base.

◆ get_other_mapping()

static core\event\base::get_other_mapping ( )

staticinherited

This is used when restoring course logs where it is required that we map the information in 'other' to it's new value in the new course.

Does nothing in the base class except display a debugging message warning the user that the event does not contain the required functionality to map this information. For events that do not store any other information this won't be called, so no debugging message will be displayed.

Example of usage:

$othermapped = array(); $othermapped['discussionid'] = array('db' => 'forum_discussions', 'restore' => 'forum_discussion'); $othermapped['forumid'] = array('db' => 'forum', 'restore' => 'forum'); return $othermapped;

If an id can not be mapped during restore we set it to core\event\base\NOT_MAPPED, example -

$othermapped = array(); $othermapped['someid'] = array('db' => 'some_table', 'restore' => core\event\base\NOT_MAPPED); return $othermapped;

Note - it isn't necessary to specify the 'db' and 'restore' values in this case, so you can also use -

$othermapped = array(); $othermapped['someid'] = core\event\base\NOT_MAPPED; return $othermapped;

The 'db' key refers to the database table and the 'restore' key refers to the name of the restore element the other value is associated with. In many cases these will be the same.

Return values

array an array of other values and their corresponding mapping
