CakePHP における HABTM association table を更新する際に便利な Behavior がこの ExtendAssociationsBehavior:

HABTM Add & Delete Behavior - The Bakery, Everything CakePHP

ただこの Behavior, CakePHP 1.2 時代に作られたもので現行版の CakePHP 2.0.x だと動作しなかったので、パッチコードを書いてみた。以下:

Usage

使い方は旧版から変更無し:

## add 
$model->habtmAdd($assoc_name, $from_id, array($to_id1, $to_id2, ...));
e.g. $this->Post->habtmAdd('PostsTag', 1, array(2, 3));

## delete
$model->habtmDelete($assoc_name, $from_id, array($to_id1, $to_id2, ...));
e.g. $this->Post->habtmAdd('PostsTag', 1, array(3));

## delete all
$model->habtmDeleteAll($assoc_name, $from_id);
