具有实体信息的Symfony2小部件数据

Question

This project was started by another developer and now there is the function for insert in a form the data from DB but in date input i can't update input with db value..

I have a problem with a data widget form. I have this code for my widget:

                ->add('borndate', 'birthday', array(
                'widget' => 'choice',
                'attr'  => array(
                    'class' => 'form-control'
                ),
                'label' => 'user.birthday.label',
                'input' => 'string',
                'format' => 'dd.MM.yyyy',
                'data' => '1950-01-01'
            ))

I would like to have the value of my entity on DB, in another widget like for example name:

->add('name','text',array(
'label'=>'user.name.label',
'required'=>true
 ))

I receive already this function but not in date.. How can i do??

So, if I understand correctly when trying to update the date value on the database you always get the original value?

The problem is that the entity manager handles DateTime like an object. If you ever want to update the date in a field you will need to create a new DateTime object to update the date.

For example, in your controller where you handle the $form->isValid() you would have to do something like this $person->setBorndate(new \DateTime([Value for the new Date]));.

Now all you have to do is get is the new value for date. Either in the variable $request or $form you should be able to find it.
