Symfony3 - Error message : Expected argument of type "EmailType", "string" given

[theOtherMarino]

Hello,

I’m new to symfony. I’m trying to create a simple contact form, but I’ve got an error message :

Uncaught PHP Exception Symfony\Component\PropertyAccess\Exception\InvalidArgumentException: “Expected argument of type “EmailType”, “string” given” at /mnt/400Go/www/sy1/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php line 255

I understand the message (the email field of my form resolves into a string), but I can’t see where to look in my code. If someone can have a look to my files, it would be great.

Best regards,

MC

Here is the entity :

// src/AppBundle/Entity/ContactSetClass.php
namespace AppBundle\Entity;
/* */
class ContactSetClass
	{
	protected $contactName;
	protected $contactEmail;
	public function getContactName()
		{
		return $this->contactName;
		}
	public function setContactName($contactName)
		{
		$this->contactName = $contactName;
		}
	public function getContactEmail()
		{
		return $this->contactEmail;
		}
	public function setContactEmail(\EmailType $contactEmail = null)
		{
		$this->contactEmail = $contactEmail;
		}
	/**
	* @var integer
	*/
	private $id;
	/**
	* Get id
	*
	* @return integer
	*/
	public function getId()
		{
		return $this->id;
		}
	}

Here is the type :

/* AppBundle/Form/Type/ContactsFormType.php */
namespace AppBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\FormType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\OptionsResolver\OptionsResolver;
//use Doctrine\ORM\EntityManager;
/* */
class ContactsFormType extends AbstractType
	{
    public function buildForm(FormBuilderInterface $builder, array $options)
    	{
        $builder
        	->setMethod('POST')
            ->add('contactName')
            ->add('contactEmail', EmailType::class, array('attr' => array('placeholder' => 'Your email address')))
            ->add('save', SubmitType::class, array('label' => 'Add contact'))
        ;
        }
    public function getName()
    	{
        return 'contacts_form';
        }
    public function configureOptions(OptionsResolver $resolver)
    	{
        $resolver->setDefaults(array(
							'data_class'=>'AppBundle\Entity\ContactSetClass',
							));
        }
    }

Here is the controller :

// src/AppBundle/Controller/ContactsFormController.php
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use AppBundle\Entity\ContactSetClass;
use AppBundle\Form\Type\ContactsFormType;
class ContactsFormController extends Controller
	{
	public function contactsFormAction(Request $request)
		{
		$contactSet=new ContactSetClass();
		$ContactsFormType=new ContactsFormType();
		$form=$this->createForm(ContactsFormType::class, $contactSet);
		$form->handleRequest($request);
		if($form->isSubmitted())
			{
			if($form->isValid())
				{
				$contactName=$form->get('contactName')->getData();
				$contactEmail=$form->get('contactEmail')->getData();

				$contactSet->setContactName($contactName);
				$contactSet->setContactEmail($contactEmail);
				
				$entityManager=$this->getDoctrine()->getManager();
				$entityManager->persist($contactSet);
				$entityManager->flush();
				return new Response('Contact '.$contactName.' has been created for '.$contactEmail.'.');
				}
			else
				{
				$message='Please correct your data.';
				}
			}
		else
			{
			$message='Not submitted ';
			}
		return $this->render('contactsForm.html.twig', array('form' => $form->createView(),'message'=>$message,));
		}
	}

Here is the ORM file :

# src/AppBundle/Resources/config/doctrine/ContactSetClass.orm.yml
AppBundle\Entity\ContactSetClass:
    type: entity
    table: contacts
    id:
        id:
            type: integer
            generator: { strategy: AUTO }
    fields:
        contactName:
            type: string
            length: 100
        contactEmail:
            type: string
            length: 100

Here is the validation file :

AppBundle\Entity\ContactSetClass:
    properties:
        contactName:
            - NotBlank: {message: "Please provide a contact name."}
            - Type: string
        contactEmail:
            - Email:
                message: The email "{{ value }}" is not a valid email address.
                checkMX: true

Here is the template :

{# app/Resources/views/default/contactsForm.html.twig #}
{% block contactsForm %}
<p style="color: Red;">{{ message }}</p>
{{ form_start(form, {'attr': {'novalidate': 'novalidate'}}) }}
{{ form_widget(form) }}
{{ form_rest(form) }}
{{ form_end(form) }}
{% endblock %}

So where is your EmailType defined? I suspect you are confusing the form EmailType with something else.

[theOtherMarino]

My form “type” is AppBundle/Form/Type/ContactsFormType.php, in which I…

use Symfony\Component\Form\Extension\Core\Type\EmailType;

which corresponds to vendor/symfony/symfony/src/Symfony/Component/Form/Extension/Core/Type/EmailType.php

In my entity, I use this EmailType for the setter :

	public function setContactEmail(\EmailType $contactEmail = null)
		{
		$this->contactEmail = $contactEmail;
		}

In my validation.yml, I use the email type :

        contactEmail:
            - Email:
                message: The email "{{ value }}" is not a valid email address.
                checkMX: true

The form field is correctly generated :

<input type="email" id="contacts_form_contactEmail" name="contacts_form[contactEmail]" required="required" placeholder="Your email address" class="form-control" />

It may be unrelated, but in my ORM file, the field is declared as a string (as there is no “email” data type for my DB).

[theOtherMarino]

It works; the setter was wrong :

public function setContactEmail($contactEmail = null)
		{
		$this->contactEmail = $contactEmail;
		}

No “\EmailType”…
