How can I create a custom DataGrid filter in SonataAdmin

Question

I have an entity Transaction with numerous status codes. I want the user to be able to see these status codes as strings in SonataAdmin. The user should also be able to filter

Answer 1

Something like that

protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
    $datagridMapper
        ->add('codes', 'doctrine_orm_callback', array(
            'label'         => 'Код',
            'callback'      => array($this, 'getCodesFilter'),
            'field_type'    => 'genemu_jquerychosen',
            'field_options' => array(
                'class'     => 'Mtools\ClientBundle\Entity\Client',
                'widget'    => 'entity',
                'multiple'  => false,
            )
        );
}

public function getCodesFilter($queryBuilder, $alias, $field, $value)
{
    if (!$value) {
        return;
    }
    $queryBuilder->leftJoin(sprintf('%s.codes', $alias), 'c');
    $queryBuilder->andWhere('c.code = :code');
    $queryBuilder->setParameter('code', $value['value']);
}
