Admingenerator,filtersandI18n_php技巧

$this->widgetSchema['name'] = new sfWidgetFormFilterInput(array('with_empty' => false)); 
$this->validatorSchema['name'] = new sfValidatorPass(array('required' => false)); 
 
2) add a query modification when filtering for that field 
I've done it for Doctrine. Pay atention to the method name addFIELDColumnQuery. 
 代码如下:

public function addNameColumnQuery(Doctrine_Query $query, $field, $values) 
{ 
if (is_array($values) && isset($values['text']) && '' != $values['text']) 
{ 
$query->leftJoin('r.Translation t') 
// ->andWhere('t.lang = ?', $especify_one_language) // or it will search in all of them 
->andWhere('CONCAT(t.name, t.shortname) like ?', '%' . $values['text'] . '%'); 
} 
} 
 
3) Add your searching fields 

 代码如下:

public function getFields() 
{ 
return parent::getFields() + array('name' => 'Text'); 
}
