How to Retrieve Form Validation Errors in Symfony2 After Request Binding?

Retrieve Form Validation Errors in Symfony2 After Request Binding

In your code snippet, you're binding the request data to the form and checking if it's valid:

<code class="php">public function saveAction()
{
    // ...

    if ($this->request->getMethod() == 'POST')
    {
        $form->bindRequest($this->request);
        if ($form->isValid())
            // ...
        else
            // ...
    }

    // ...
}</code>

To obtain the validation errors if $form->isValid() returns false, you have two options:

Option 1: Display Errors in Template File

Avoid redirecting the user on error and instead display the errors in the template file using:

<code class="twig">{{ form_errors(form) }}</code>

Option 2: Access Error Array

Retrieve the error array directly from the form using:

<code class="php">$form->getErrors()</code>

This returns an array of errors, which you can iterate through to display or handle as needed.
