Symfony2: Retrieving Form Validation Errors Post Request Binding

Problem:

In the provided saveAction method for Symfony2, the form is bound to the HTTP request and validated. However, if validation fails, how can one retrieve the validation errors?

Solution:

There are two common approaches to obtaining validation errors when $form->isValid() returns false:

1. Displaying Errors in the Template:

• Keep the user on the current page after validation failure.
• Use the {{ form_errors(form) }} Twig helper in the template to display the validation errors.

2. Accessing Error Array:

• Use the $form->getErrors() method to retrieve an array of validation errors.
• This array can be used to handle errors within the controller or display them manually.
