Overriding Default FOSUserBundle Forms: form name unchanged

[mohamedaymenkarmous]

Symfony FOSUserBundle version 2.1.2:

Hello,

I'm using Symfony 4.3.1 and I followed this documentation to override the default FOSUserBundle and it looks great.

The only problem is about the form name (including form elements name) which is always "fos_user_registration_form"

Example:

<form name="fos_user_registration_form" method="post" action="/api/user_register" class="fos_user_registration_register">
   <div id="fos_user_registration_form">
      <div><label for="fos_user_registration_form_email" class="required">Email</label><input type="email" id="fos_user_registration_form_email" name="fos_user_registration_form[email]" required="required" /></div>
      <div><label for="fos_user_registration_form_username" class="required">Username</label><input type="text" id="fos_user_registration_form_username" name="fos_user_registration_form[username]" required="required" maxlength="180" pattern=".{2,}" /></div>
      <div><label for="fos_user_registration_form_plainPassword_first" class="required">Password</label><input type="password" id="fos_user_registration_form_plainPassword_first" name="fos_user_registration_form[plainPassword][first]" required="required" autocomplete="new-password" /></div>
      <div><label for="fos_user_registration_form_plainPassword_second" class="required">Repeat password</label><input type="password" id="fos_user_registration_form_plainPassword_second" name="fos_user_registration_form[plainPassword][second]" required="required" autocomplete="new-password" /></div>
   </div>
   <div>
      <input type="submit" value="Register" />
   </div>
</form> 

I searched how to override that form name "fos_user_registration_form" and I found two ways:

• Overriding \AcmeBundle\Form\Type\RegistrationType::getBlockPrefix() method

• Defining fos_user.registration.form.name attribute on the config/packages/fos_user.yaml file

But none of them works: form name is always "fos_user_registration_form".

So, I was forced to dig into the FOSUserBundle source code and I found something strange:

1) Inside Controller/RegistrationController.php file

When I replace this line:

$form = $this->formFactory->createForm();

With these lines

$form = $this->createForm(\AcmeBundle\Form\Type\RegistrationType::class, $user, array());

The form name changes to the configured name inside \AcmeBundle\Form\Type\RegistrationType::getBlockPrefix() which is logical (the behavior of Symfony).

But why FOSUserBundle is not using the Type class configured on fos_user.registration.form.type when the form is created ? (createForm method)

So i digged more inside another file

2) Inside Form/Factory/FormFactory.php file

Excuse my misunderstanding if I made a mistake but what I understood from the previous file that Form/Factory/FormFactory.php::createForm() is the method that creates the form but when I tried to debug inside this file (I mean inside the __construct() or the createForm() methods) using dump();exit(); I got nothing. Which means that createForm() is not called from this file.

3) Last test

I reproduced the first test and I removed \AcmeBundle\Form\Type\RegistrationType::getBlockPrefix() method so I get another form name (I think it's the default form name generated by Symfony) which is not "fos_user_registration_form".

Conclusion

So I think there is a problem with this line. I'm not an expert of Symfony. But this is what I can conclude after these tests. It's like the custom ReigstrationType is not used because like I showed on the first test: when we hardcode the Form Type in the form creation, everything works fine.

I don't want to keep that form name for some reason.

Can anyone help me to find the problem ?

My fos_user.yaml file content:

fos_user:
    db_driver: orm
    firewall_name: main
    user_class: AcmeBundle\Entity\User
    group:
        group_class:   AcmeBundle\Entity\Group
    service:
        user_manager: pugx_user_manager
    registration:
        form:
            type: AcmeBundle\Form\Type\RegistrationType
            name: user_acme_registration
            validation_groups: [Creation, Default]
        confirmation:
            enabled: false
