Symfony 2 form type add custom select

Question

I have a Symfony 2.3.4 form type that works, and one of the HTML tags that the form has is a select:

            ->add('aIdWorkerStatus', 'entity', array('class'   => 'OsdRetireBundle:WorkerStatus'
                , 'property' => 'description'))

The Entity WorkerStatus, has a few values and IDs and it works perfectly like that. But I have been struggling to add an arbitrary value in the select that displays a 'All' option on the select drop down list. Can any one help me? Regards and thank you.

empty_value is what you are looking for :

->add('aIdWorkerStatus', 'entity', array('class'   => 'OsdRetireBundle:WorkerStatus'
                , 'property' => 'description', 'empty_value' => 'All'))
