public CActiveRecord add( $... )
Attaches tags to model.
Can be called with any number of arguments of any type. Only constraint is that Object arguments should have __toString defined (Not applicable to instances of tag model).
Usage example:
$user->tags->add( 'test', Array( 'admin', 10 ), $user )->save();
// This code will attach to the model following tags: 'test', 'admin', '10', 'User_1' ($user->__toString())
public CMap get( CDbCriteria $additionalCriteria = null )
Returns all attached to the model tags.
Parameters:
additionalCriteria - Additional DB criteria to filter attached tags. Will be passed to CDbCriteria::mergeWith().
Usage example:
$tagsList = $user->tags->get();
public bool has( $... )
Checks whether or not specified tags are attached to the model.
Can be called with any number of arguments of any type. Only constraint is that Object arguments should have __toString defined (Not applicable to instances of tag model).
Returns true only if ALL specified tags are attached to the model.
Usage example:
// if tags 'test', 'admin' и '10' are attached to the user
if ( $user->tags->has( 'test', Array( 'admin' ), 10 ) ) {
...
}
public CActiveRecord remove( $... )
Detaches specified tags from the model.
Can be called with any number of arguments of any type. Only constraint is that Object arguments should have __toString defined (Not applicable to instances of tag model).
Usage example:
$user->tags->remove( 'test', Array( 'admin', 10 ), $user )->save();
// This code will detach from the user follwoing tags: 'test', 'admin', '10', 'User_1' ($user->__toString())
public CActiveRecord reset( void )
Detaches all tags from the model.
Usage example:
$user->tags->reset()->save();
public CActiveRecord set( $... )
Attaches to the model specified set of tags that will replace all previous ones.
Can be called with any number of arguments of any type. Only constraint is that Object arguments should have __toString defined (Not applicable to instances of tag model).
Usage example:
// attaching of tags 'test', 'admin', '10'
$user->tags->add( 'test', Array( 'admin', 10 ) );
// removing all previously attached tags ('test', 'admin', '10')
// and attaching new ones: 'newTest', 'Array' и 'blah'
$user->tags->set( Array( 'newTest', Array( 11 ) ), 'blah' )->save();
public CActiveRecord taggedWith( $... )
Modifies the model DB criteria in order to find models with any of specidied tags attached.
Can be called with any number of arguments of any type. Only constraint is that Object arguments should have __toString defined (Not applicable to instances of tag model).

public string __toString( void )
Allows all attached to the model tags to be printed imploded by separator.
// attaching of tags 'test', 'admin', '10'
$user->tags->add( 'test', Array( 'admin', 10 ) );
print $user->tags;
// will be printed: 'test,admin,10'
