我找不到错误原因

I couldn't find error reason

我正在尝试在 symfony2 中创建一个简单的博客。但不幸的是,我在尝试在 symfony2 中创建表单时遇到问题,代码如下

<?php
/**
 * Created by PhpStorm.
 * User: kanat
 * Date: 2/13/16
 * Time: 8:11 PM
 */
namespace Blogger\BlogBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class EnquiryType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name');
        $builder->add('email', 'email');
        $builder->add('subject');
        $builder->add('body', 'textarea');
    }

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

位于Blogger\BlogBundle\Form\EnquiryType。php 错误是:

Expected argument of type "string", >"Blogger\BlogBundle\Form\EnquiryType" given

我不知道如何解决这个问题。请帮助我

您的版本,但错误:

$form = $this->createForm(new EnquiryType(), $yourEntity);

您必须使用:

$form = $this->createForm(EnquiryType::class, $yourEntity);

控制器:

public function contactAction() {
    $enquiry = new Enquiry();
    $form = $this->createForm(EnquiryType::class, $enquiry);
