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$rowDatabase row result. Default is null to create a new object.
Exceptions
IOExceptionIf cannot load remaining data from db

Definition at line 122 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 165 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$nameName of the attribute or metadata
Returns
mixed

Definition at line 293 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$nameName of the attribute or metadata
mixed$valueThe value to be set
Returns
void
Exceptions

Definition at line 218 of file ElggEntity.php.

ElggEntity::cache ( )

Cache the entity in a session cache.

Returns
void

Definition at line 1315 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$user_guidUser guid (default is logged in user)
string$annotation_nameThe name of the annotation (default is unspecified)
Returns
bool

Definition at line 460 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_guidUser guid (default is logged in user)
Returns
bool

Definition at line 442 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_guidThe user GUID, optionally (default: logged in user)
Returns
bool Whether this entity is deletable by the given user.
Since
1.11

Definition at line 411 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_guidThe user GUID, optionally (default: logged in user)
Returns
bool Whether this entity is editable by the given user.

Definition at line 397 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$user_guidThe GUID of the user creating the entity (0 for logged in user).
string$typeThe type of entity we're looking to write
string$subtypeThe subtype of the entity we're looking to write
Returns
bool
Exceptions

Definition at line 425 of file ElggEntity.php.

ElggEntity::countComments ( )

Count the number of comments attached to this entity.

Returns
int Number of comments
Since
1.8.0

Definition at line 361 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 if prevented by an event handler
Exceptions

Definition at line 614 of file ElggEntity.php.

ElggEntity::delete ( bool  $recursive = true,
bool  $persistent = null 
)

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 = $this->guid, the item will be deleted regardless of who owns it.
Parameters
bool$recursiveIf true (default) then all entities which are owned or contained by $this will also be deleted.
bool | null$persistentpersistently delete the entity (default: check the 'restorable' capability)
Returns
bool

Definition at line 1021 of file ElggEntity.php.
