Overriding Default FOSUserBundle Forms ====================================== ## Overriding a Form Type The default forms packaged with the FOSUserBundle provide functionality for registering new user, updating your profile, changing your password and much more. These forms work well with the bundle's default classes and controllers. But, as you start to add more properties to your `User` class or you decide you want to add a few options to the registration form you will find that you need to override the forms in the bundle. Suppose that you have created an ORM user class with the following class name, `Acme\UserBundle\Entity\User`. In this class, you have added a `name` property because you would like to save the user's name as well as their username and email address. Now, when a user registers for your site they should enter in their name as well as their username, email and password. Below is an example `$name` property and its validators. ``` php // src/Acme/UserBundle/Entity/User.php By default, the Registration validation group is used when validating a new > user registration. Unless you have overridden this value in the configuration, > make sure you add the validation group named Registration to your name property. If you try and register using the default registration form you will find that your new `name` property is not part of the form. You need to create a custom form type and configure the bundle to use it. The first step is to create a new form type in your own bundle. The following class extends the base FOSUserBundle `RegistrationFormType` and then adds the custom `name` field. ``` php // src/Acme/UserBundle/Form/Type/RegistrationFormType.php add('name'); } public function getName() { return 'acme_user_registration'; } } ``` Now that you have created your custom form type, you must declare it as a service and add a tag to it. The tag must have a `name` value of `form.type` and an `alias` value that is the equal to the string returned from the `getName` method of your form type class. The `alias` that you specify is what you will use in the FOSUserBundle configuration to let the bundle know that you want to use your custom form. Below is an example of configuring your form type as a service in XML: ``` xml %fos_user.model.user.class% ``` Or if you prefer YAML: ``` yaml # src/Acme/UserBundle/Resources/config/services.yml services: acme_user.registration.form.type: class: Acme\UserBundle\Form\Type\RegistrationFormType arguments: [%fos_user.model.user.class%] tags: - { name: form.type, alias: acme_user_registration } ``` **Note:** > In the form type service configuration you have specified the `fos_user.model.user.class` > container parameter as a constructor argument. Unless you have redefined the > constructor in your form type class, you must include this argument as it is a > requirement of the FOSUserBundle form type that you extended. Finally, you must update the configuration of the FOSUserBundle so that it will use your form type instead of the default one. Below is the configuration for changing the registration form type in YAML. ``` yaml # app/config/config.yml fos_user: # ... registration: form: type: acme_user_registration ``` Note how the `alias` value used in your form type's service configuration tag is used in the bundle configuration to tell the FOSUserBundle to use your custom form type. **Note:** > If you need to add some logic to the processing of the form, you can use > a listener [hooking into the controller](controller_events.md).
