Sonata User : Override registration form

2 min readFeb 1, 2018

There are many tutorials about overriding registration form .
But , if you have both FOSUser and SonataAdmin installed, the task is not as easy as you think because you don’t know which entity is managed by the framework .

Scrolling directory structure , you find many classes has the name of User.php
So , you should understand with is the final entity to be added to the database after registration .

FOSUser is the bundle which provide the entity User management .
And this entity is the one which is under SonataUser.


#config/packages/fos_user.yamlfos_user:    #...
    user_class: Sonata/UserBundle/Entity/User

The class at the top is our beloved . The following architecture is done to get both FOSUser and Sonata User attributes .

Now ,If you understand the final entity, you can execute the following steps easily :

Create a folder “Form” under src
Create a new Form : RegistrationType

<?php
namespace App\Form;use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;class RegistrationType extends AbstractType{public function buildForm(FormBuilderInterface $builder, array $options){   
    $builder
         ->add('website')
         ->add('dateOfBirth');
}public function getParent()
{
return 'FOS\UserBundle\Form\Type\RegistrationFormType';
}public function getBlockPrefix()
{ 
    return 'app_user_registration';
}}

3. Add to buildForm action attributes you wish to add to registration form

In this example , I added website and dateOfBirth

warning : be careful of the spelling. It’s wiser to copy the attribute name from its declaration .

4. Tell FOSUser that the new form is no longer the default one . So add the new path under registration.form:

#config/packages/fos_user.yamlfos_user:
    registration:
       #..
       form:
            type: App\Form\RegistrationType    #...
    user_class: Sonata/UserBundle/Entity/User

5. Now , browse 127.0.0.1:8000/register
