Question

当我将表单移动到表单类时，显示我的新表单时出现问题，我真的不知道如何处理此问题

我使用Symfony 3.0.4。我认为我从Symfony文档和StackOverFlow的提示中搜索了所有内容，但很多这些数据来自Symfony 2.x。

对象“Symfony \ Component \ Form \ FormView”的方法“保存”没有存在于FlexPMUsersBundle中：默认值：register.html.twig，第8行500 内部服务器错误 - Twig_Error_Runtime

我有4个文件：

的src / FlexPM / UsersBundle /资源/视图/默认/ register.html.twig

{% extends 'base.html.twig' %}

{% block body %}
<div>
    Test
    {{ form_start(formRegister) }}
        {{ form_errors(formRegister) }}

        {{ form_row(formRegister.save) }}
    {{ form_end(formRegister) }}

</div>
{% endblock %}

你知道我该怎么办？

---解决方案---：

的src / FlexPM / UsersBundle /窗体/类型/ UserRegister.php

<?php
// src/FlexPM/Form/Type/UserRegister.php
namespace FlexPM\UsersBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\OptionsResolver\OptionsResolver;

class UserRegister extends AbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('save', SubmitType::class)
        ;
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'FlexPM\UsersBundle\Entity\Users',
        ));
    }

}

Answer 1

registerForm函数不应该是buildForm吗？我不认为registerForm被调用，因为你试图手动输出按钮{{ form_row(formRegister.save) }}，它会抛出你收到的错误。
