Question

抬头 - 我已经here了。 Symfony3形式的奇怪问题。所以我创建了FormType类：

class GetPostType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->setMethod("POST")
            ->add('phrase', Type\TextType::class);
    }
}

如您所见，表单不受任何实体或其他对象的约束（尽管这应该无关紧要）。现在，当我尝试使用该表单处理传入请求时：

$postForm = $this->createForm(GetPostType::class);
$postForm->handleRequest($this->request);

...通常handleRequest应该提交我的表格。但是：

$postForm->isSubmitted();

是假的。

我已将问题来源追溯到 HttpFoundationRequestHandler 。

} elseif ($request->request->has($name) || $request->files->has($name)) {

据此，我的表格名称不在请求中。这就是我没有得到的。我在工作中使用Symfony表单，没有问题。我在不同的项目中使用它们，这没关系。现在由于某种原因，我不能让他们工作。这可能是显而易见的事情，但我想我需要另外一双眼睛才能看到它。

正如您所看到的，我确实尝试手动设置表单方法（默认情况下应该是POST）但它不起作用。我确实清除了缓存和内容。我确实尝试过在互联网上找到的不同的东西，但没有运气。

我找不到任何可能的原因。任何想法可能是什么？

更新

根据评论部分的要求，我提供了我的请求对象的转储。那么我怎么知道这是正确的呢？它被handleRequest方法接受，它希望请求类型包含正确的数据。

表单呈现的实际字段名为get_post[phrase]，而不仅仅是phrase。在邮递员中提交get_post[phrase]将有效。

如果您不想要这种命名方案，可以覆盖表单中的getBlockPrefix方法，例如：

<?php

namespace AppBundle\Form;

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

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

class GetPostType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('phrase', TextType::class);
    }

    public function getBlockPrefix()
    {
        return null;
    }
}

Symfony3.3表单名称不在请求
