Three easy steps

1) configure function

Add an input for each field you want to include in your filter

复制代码 代码如下:

$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.

复制代码 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

复制代码 代码如下:

public function getFields()

{

return parent::getFields() + array('name' => 'Text');

}
