Access POST values in Symfony2 request object
提问by Acyra
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:
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：
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');
Unfortunately $name_valueisn't returning anything. What am I doing wrong? Thanks!
不幸的$name_value是没有返回任何东西。我究竟做错了什么？谢谢！

The form post values are stored under the name of the form in the request. For example, if you've overridden the getName()method of ContactType() to return "contact", you would do this:
表单发布值存储在请求中表单的名称下。例如，如果您覆盖了getName()ContactType()的方法以返回“contact”，您将执行以下操作：
$postData = $request->request->get('contact');
$name_value = $postData['name'];
If you're still having trouble, try doing a var_dump()on $request->request->all()to see all the post values.
如果您还是有问题，尝试做一个var_dump()上$request->request->all()看到所有的提交值。

this solution is deprecated since 2.3 and will be removed in 3.0, see documentation
此解决方案自 2.3 起已弃用，并将在 3.0 中删除，请参阅文档
$form->getData();
gives you an array for the form parameters
给你一个表单参数数组
from symfony2 bookpage 162 (Chapter 12: Forms)
来自symfony2 书第 162 页（第 12 章：表格）
[...] 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:
[...] 有时，您可能只想使用没有类的表单，并获取提交数据的数组。这实际上非常简单：
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
}
You can also access POST values (in this case "name") directly through the request object, like so:
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：
$this->get('request')->request->get('name');
Be advised, however, that in most cases using the getData() method is a better choice, since it returns the data (usually an object) after it's been transformed by the form framework.
但是，请注意，在大多数情况下，使用 getData() 方法是更好的选择，因为它在被表单框架转换后返回数据（通常是一个对象）。
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
当您想访问表单令牌时，您必须使用问题的答案，
$postData = $request->request->get('contact');因为getData()从数组中删除元素

Symfony 2.3
since 2.3 you should use handleRequestinstead of bindRequest:
从 2.3 开始，您应该使用handleRequest代替bindRequest：
$form->handleRequest($request);

what worked for me was using this:
对我有用的是使用这个：
$data = $request->request->all();
$name = $data['form']['name'];

There is one trick with ParameterBag::get()method. You can set $deepparameterto trueand access the required deep nested value without extra variable:
方法有一个技巧ParameterBag::get()。您可以将$deep参数设置为true并访问所需的深度嵌套值，而无需额外的变量：
$request->request->get('form[some][deep][data]', null, true);
Also you have possibility to set a default value (2nd parameter of get()method), it can avoid redundant isset($form['some']['deep']['data'])call.
您也可以设置默认值（get()方法的第二个参数），它可以避免冗余isset($form['some']['deep']['data'])调用。

The field data can be accessed in a controller with: Listing 12-34
可以在控制器中访问字段数据：清单 12-34
$form->get('dueDate')->getData();
In addition, the data of an unmapped field can also be modified directly: Listing 12-35
另外，未映射字段的数据也可以直接修改：示例12-35
$form->get('dueDate')->setData(new \DateTime());

I think that in order to get the request data, bound and validated by the form object, you must use :
我认为为了获取由表单对象绑定和验证的请求数据，您必须使用：
$form->getClientData();
$form->getClientData();

If you are newbie, welcome to Symfony2, an open-source project so if you want to learn a lot, you can open the source !
如果你是新手，欢迎来到 Symfony2，一个开源项目，所以如果你想学到很多东西，你可以开源！
