我遇到令牌和文件字段表单的问题.

表单的验证如下:

public function getDefaultOptions(array $options)
{
    $collectionConstraint = new Collection(array(
        'fields' => array(
            'file' => new File(
                array(
                    'maxSize' => '2M',
                    'mimeTypes' => array(
                        'application/pdf', 'application/x-pdf',
                        'image/png', 'image/jpg', 'image/jpeg', 'image/gif',
                    ),
                )
            ),
        )
    ));

    return array(
        'validation_constraint' => $collectionConstraint
}

当我上传一个无效的大小文件(~5MB)时,我得到了这个错误,这是我希望的:

The file is too large. Allowed maximum size is 2M bytes

但是当我上传一个太大的文件(~30MB)时,错误会发生变化:

The CSRF token is invalid. Please try to resubmit the form
The uploaded file was too large. Please try to upload a smaller file

问题是错误令牌.我的格式是{{form_rest(form)}}代码.我认为错误更改是因为: …

我有这个例子的Symfony2文档的基本表单,模板和控制器操作.

每当我尝试在控制器操作中获取表单的参数时,我必须使用此:

$parameters = $request->request->all();
$name = $parameters["form"]["name"];

但是,在文档中使用此:

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

但这对我来说是错误的,在这种情况下$ name为null并且Object请求(ParameterBag)包含:

object(Symfony\Component\HttpFoundation\ParameterBag)#8 (1) {
  ["parameters":protected]=>
  array(1) {
    ["form"]=>
    array(1) {
      ["name"]=>
      string(4) "test"
    }
  }
}
