Writing Hydration Method
Doctrine offers the ability to write your own hydration methods and register them with
Doctrine for use. All you need to do is write a class that extends
Doctrine_Hydrator_Abstract and register it with Doctrine_Manager.
First lets write a sample hydrator class:
class Doctrine_Hydrator_MyHydrator extends Doctrine_Hydrator_Abstract
{
public function hydrateResultSet($stmt)
{
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);
// do something to with $data
return $data;
}
}
To use it make sure we register it with Doctrine_Manager:
Listing
14-12
// bootstrap.php
// ...
$manager->registerHydrator('my_hydrator', 'Doctrine_Hydrator_MyHydrator');
Now when you execute your queries you can pass my_hydrator and it will use your class to
hydrate the data.
Listing
14-13
$q->execute(array(), 'my_hydrator');
