Question

I have a form type which has a field that is not in the entity as a property, but the entity has a getter and a setter with the same name as form field, explaining:

Form type:

$builder->add('theField', 'entity', array(
    'label' => 'The field',
    'class' => 'MyAppBundle:AnEntity',
    'empty_value' => '',
));

Entity:

class User
{
    //There is NOT a property called "theField"

    public function setTheField($value)
    {
        ...
    }

    public function getTheField()
    {
        ...
    }
}

So, I’m expected that Symfony2 call the getter and setter to bind and show the form field, but I get this error:

Property theField does not exists in class My\AppBundle\Entity\User

Is there a way to create this form field without having the property declared in entity?

EDIT

Is strange, but when I declare a private property theField, it’s works (BTW, that is not what I looking for).

Answer 1

Did you try:

$builder->add('theField', 'entity', array(
    'label' => 'The field',
    'class' => 'MyAppBundle:AnEntity',
    'empty_value' => '',
    'property_path' => false,
));

Update

Change your field name to the same as attribute in the entity or change 'property_path' to the attribute name.

$builder->add('theField', 'entity', array(
    'label' => 'The field',
    'class' => 'MyAppBundle:AnEntity',
    'empty_value' => '',
    'property_path' => 'theField',
));

And in your entity add:

private $theField = null;
