访问 Symfony2 请求对象中的 POST 值 [英] Access POST values in Symfony2 request object

问题描述

好的，这是一个新手问题，但我在任何地方都找不到答案.在 Symfony2 的控制器中，我想从我的表单之一访问 POST 值.在控制器中我有:

OK, this is a newbie question, but I can't find the answer anywhere. In a controller in Symfony2, I want to access the POST value from one of my forms. In the controller I have:

public function indexAction()
{ 
    $request = $this->get('request');
    if ($request->getMethod() == 'POST') {
        $form = $this->get('form.factory')->create(new ContactType());
        $form->bindRequest($request);
        if ($form->isValid()) {
            $name_value = $request->request->get('name');

不幸的是 $name_value 没有返回任何东西.我究竟做错了什么?谢谢！

Unfortunately $name_value isn't returning anything. What am I doing wrong? Thanks!

推荐答案

Symfony 2.2

此解决方案自 2.3 起已弃用，将在 3.0 中删除，查看文档

$form->getData();

给你一个表单参数数组

来自symfony2 book第162页(第12章:表格)

from symfony2 book page 162 (Chapter 12: Forms)

[...] 有时，您可能只想使用没有类的表单，并返回提交的数组数据.这实际上非常简单:

[...] sometimes, you may just want to use a form without a class, and get back an array of the submitted data. This is actually really easy:

public function contactAction(Request $request) {
  $defaultData = array('message' => 'Type your message here');
  $form = $this->createFormBuilder($defaultData)
  ->add('name', 'text')
  ->add('email', 'email')
  ->add('message', 'textarea')
  ->getForm();
  if ($request->getMethod() == 'POST') {
    $form->bindRequest($request);
    // data is an array with "name", "email", and "message" keys
    $data = $form->getData();
  }
  // ... render the form
}

您还可以直接通过请求对象访问 POST 值(在本例中为名称")，如下所示:

You can also access POST values (in this case "name") directly through the request object, like so:

$this->get('request')->request->get('name');

但是请注意，在大多数情况下，使用 getData() 方法是更好的选择，因为它返回表单框架转换后的数据(通常是对象).

当你想访问表单令牌时，你必须使用Problematica的答案$postData = $request->request->get('contact'); 因为 getData() 从数组中删除元素

When you want to access the form token, you have to use the answer of Problematic $postData = $request->request->get('contact'); because the getData() removes the element from the array

从 2.3 开始，您应该使用 handleRequest 而不是 bindRequest:

since 2.3 you should use handleRequest instead of bindRequest:

 $form->handleRequest($request);
