Question

I have build a form class to generate a form that will allow a user to type in a new password twice in order to change it.

code:

<?php

namespace UserBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
use Symfony\Component\Form\FormError;
use Symfony\Component\Form\CallbackValidator;

class PasswordType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder->add('password', null);
        $builder->add('confirmPassword', null, array('label' => 'Confirm Password', 'property_path' => false));
        $builder->addValidator(new CallbackValidator(function($form)
            {
                if($form['confirmPassword']->getData() != $form['password']->getData()) {
                    $form['confirmPassword']->addError(new FormError('Passwords must match.'));
                }
            }));
    }

    public function getDefaultOptions(array $options)
    {
        return array(
            'data_class' => 'UserBundle\Entity\User',
        );
    }

    public function getName()
    {
        return 'password';
    }
}

Now, this class works pretty well, BUT my issues is that when I set the first password field to type “password” I get this error:

Circular reference detected in the “password” type (defined in class “UserBundle\Form\Type\PasswordType”).

And I cannot leave it set to “null” as it will use a normal text input field, which is not ideal.

Any ideas folks?

Answer 1

The issue seems to be from using “password” as the getName() value.

Before:

public function getName()
{
    return 'password';
}

After:

public function getName()
{
    return 'changePassword'; // basically anything other than 'password'
}

I changed this to “pass” and now I can use “password” to set the type, i.e.

$builder->add('password', 'password');
