How can I filter several fields in one filter?

Question

Is possible to create search filter to search from not one field, but from CONCAT(name, description) ?

protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
    $datagridMapper->add('search');
}

Answer 1

I found solution with doctrine_orm_callback type

protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{


    $datagridMapper
        ->add( 'text', 'doctrine_orm_callback', array(
            'callback' => array($this, 'getSearchFilter'),
            'field_type' => 'text'
        ) );
}

public function getSearchFilter($queryBuilder, $alias, $field, $value) {
    if (!$value['value']) {
        return;
    }

    $exp = new \Doctrine\ORM\Query\Expr();
    $queryBuilder->andWhere($exp->like($exp->concat($alias.'.name', $alias.'.description'), $exp->literal('%' . $value['value'] . '%')));

    return true;
}
