Constructor & Destructor Documentation

ElggEntity::__construct ( stdClass $row = null )

Create a new entity.

Plugin developers should only use the constructor to create a new entity. To retrieve entities, use get_entity() and the elgg_get_entities* functions.

If no arguments are passed, it creates a new entity. If a database result is passed as a instance, it instantiates that entity.

Parameters

stdClass $row Database row result. Default is null to create a new object.

Exceptions

IOException If cannot load remaining data from db

Definition at line 134 of file ElggEntity.php.

Member Function Documentation

ElggEntity::__clone ( )

Clone an entity.

Resets the guid so that the entity can be saved as a distinct entity from the original. Creation time will be set when this new entity is saved. The owner and container guids come from the original entity. The clone method copies metadata but does not copy annotations.

Returns: void

Definition at line 175 of file ElggEntity.php.

ElggEntity::__get ( $name )

Get an attribute or metadata value.

If the name matches an attribute, the attribute is returned. If metadata does not exist with that name, a null is returned.

This only returns an array if there are multiple values for a particular $name key.

Parameters

string $name Name of the attribute or metadata

Returns: mixed

Definition at line 299 of file ElggEntity.php.

ElggEntity::__set	(	$name,
		$value
	)

Set an attribute or metadata value for this entity.

Anything that is not an attribute is saved as metadata.

Be advised that metadata values are cast to integer or string. You can save booleans, but they will be stored and returned as integers.

Parameters

string	$name	Name of the attribute or metadata
mixed	$value	The value to be set

Returns: void

Exceptions

Definition at line 228 of file ElggEntity.php.

ElggEntity::addRelationship	(	int	$guid_two,
		string	$relationship
	)

Add a relationship between this an another entity.

Read the relationship like "This entity is a $relationship of $guid_two."

Parameters

int	$guid_two	GUID of the target entity of the relationship
string	$relationship	The type of relationship

Returns: bool

Exceptions

Definition at line 539 of file ElggEntity.php.

ElggEntity::annotate	(	$name,
		$value,
		$access_id = `ACCESS_PRIVATE`,
		$owner_guid = `0`,
		$value_type = `''`
	)

Adds an annotation to an entity.

Warning: By default, annotations are private.; Annotating an unsaved entity more than once with the same name will only save the last annotation.

Parameters

string	$name	Annotation name
mixed	$value	Annotation value
int	$access_id	Access ID
int	$owner_guid	GUID of the annotation owner
string	$value_type	The type of annotation value

Returns: bool|int Returns int if an annotation is saved

Definition at line 757 of file ElggEntity.php.

ElggEntity::cache ( bool $persist = true )

Cache the entity in a session and persisted caches.

Parameters

bool $persist Store in persistent cache

Returns: void

Definition at line 1925 of file ElggEntity.php.

ElggEntity::canAnnotate	(	int	$user_guid = `0`,
		string	$annotation_name = `''`
	)

Can a user annotate an entity?

Can be overridden by registering for the event [permissions_check:annotate:<name>, <entity type>="">] or [permissions_check:annotate, <entity type>="">]. The events are called in that order.

If you want logged out users to annotate an object, do not call canAnnotate(). It's easier than using the event.

Parameters

int	$user_guid	User guid (default is logged in user)
string	$annotation_name	The name of the annotation (default is unspecified)

Returns: bool

Definition at line 1009 of file ElggEntity.php.

ElggEntity::canComment ( int $user_guid = 0 )

Can a user comment on an entity?

Can be overridden by registering for the 'permissions_check:comment', '<entity type>="">' event.

Parameters

int $user_guid User guid (default is logged in user)

Returns: bool

Definition at line 991 of file ElggEntity.php.

ElggEntity::canDelete ( int $user_guid = 0 )

Can a user delete this entity?

Can be overridden by registering for the permissions_check:delete event.

Parameters

int $user_guid The user GUID, optionally (default: logged in user)

Returns: bool Whether this entity is deletable by the given user.

Since: 1.11

Definition at line 960 of file ElggEntity.php.

ElggEntity::canEdit ( int $user_guid = 0 )

Can a user edit this entity?

Can be overridden by registering for the permissions_check event.

Parameters

int $user_guid The user GUID, optionally (default: logged in user)

Returns: bool Whether this entity is editable by the given user.

Definition at line 946 of file ElggEntity.php.

ElggEntity::canWriteToContainer	(	int	$user_guid = `0`,
		string	$type = `''`,
		string	$subtype = `''`
	)

Can a user add an entity to this container.

Parameters

int	$user_guid	The GUID of the user creating the entity (0 for logged in user).
string	$type	The type of entity we're looking to write
string	$subtype	The subtype of the entity we're looking to write

Returns: bool

Exceptions

Definition at line 974 of file ElggEntity.php.

ElggEntity::countAnnotations ( string $name = '' )

Count annotations.

	)

Gets the number of entities from a specific relationship type.

Parameters

string	$relationship	Relationship type (eg "friends")
bool	$inverse_relationship	Invert relationship

Returns: int

Definition at line 594 of file ElggEntity.php.

ElggEntity::create ( )

protected

Create a new entry in the entities table.

Saves the base information in the entities table for the entity. Saving the type-specific information is handled in the calling class method.

Returns: int|false The new entity's GUID or false on failure

Exceptions

Definition at line 1260 of file ElggEntity.php.

ElggEntity::delete ( bool $recursive = true )

Deletes the entity.

Removes the entity and its metadata, annotations, relationships, river entries, and private data.

Optionally can remove entities contained and owned by this entity.

Warning: If deleting recursively, this bypasses ownership of items contained by the entity. That means that if the container_guid = $this->guid, the item will be deleted regardless of who owns it.

Parameters

bool $recursive If true (default) then all entities which are owned or contained by $this will also be deleted.

Returns: bool
