Check out Serializable Behavior API Documentation
Serializable Behaviour for CakePHP 2.1+
Use it if you want to save and read serialized data into db.
cd my_cake_app/app
git clone git://github.com/imsamurai/cakephp-serializable-behaviour.git Plugin/Serializable
or if you use git add as submodule:
cd my_cake_app
git submodule add "git://github.com/imsamurai/cakephp-serializable-behaviour.git" "app/Plugin/Serializable"
then add plugin loading in Config/bootstrap.php
CakePlugin::load('Serializable');
Write global config if you need to use custom serialization function:
Configure::write('Serializable', array(
'serialize' => <valid callable>,
'unserialize' => <valid callable>
));
Attach behaviour to model:
public $actsAs = array(
'Serializable.Serializable' => array(
'fields' => <array of field names>,
'serialize' => <valid callable>, // optional
'unserialize' => <valid callable> // optional
'merge' => true // optional
)
);
By default serialization uses function serialize
, unserialization - unserialize
Merging is off by default, turning it on will do a recursive merge on existing records so you can add data without replacing the entire serialized object.
If you want to use serialization with Containable behaviour you must modify your AppModel. For example we have 3 models that extedned AppModel: NewsPopular has many NewsPopularItem NewsPopularItem belongs to Article
NewsPopularItem and Article has some serialized fields.
Assume you want to fetch data this way:
$this->NewsPopular->contain(array(
'NewsPopularItem' => array(
'Article'
)
));
$data = $this->NewsPopular->find('first');
In this case you must add some configuration to AppModel::afterFind. In basic case there must be:
public function afterFind($results, $primary = false) {
if (!$primary && $this->Behaviors->enabled('Serializable')) {
return $this->Behaviors->Serializable->afterFind($this, $results, $primary);
}
return parent::afterFind($results, $primary);
}
And that's all! Now you have data structure with unserialized fields.
