我在Symfony2.8中使用表单构建器和FOS UserBundle设置默认变量时遇到问题
/**
* @Route("/add/{id}", name="add")
* @Template("add.html.twig")
*/
public function createFormAction ($id, Request $request)
{
$user = $this->container->get('security.context')->getToken()->getUser();
$username = $user->getUsername();
$userid = $user->getId();
$repo = $this->getDoctrine()->getRepository('AppBundle:Place');
$pl = $repo->find($id);
//var_dump($us);
$form = $this -> createFormBuilder ($pl)
-> add( "id" , "integer" )
-> add( "placeuser", NULL)
-> add( "priceperhour", "hidden", array( "mapped" => false))
-> add( "rentdate" , "date" )
-> add( "rentlength" , "integer" )
->add( 'save', 'submit', array('label' => 'Add'))
-> getForm ();
$form->handleRequest($request);
if ($form->isSubmitted())
{
$pl = $form->getData();
$em = $this->getDoctrine()->getManager();
$em->flush();
return $this->redirectToRoute('reservation');
}
Return $this -> render ( 'add.html.twig' , [ 'form' => $form -> createView ()]);
}
请看 - ＆gt;在结果中添加（“placeuser”，NULL）我收到了包含表中所有用户名的下拉菜单。
我尝试更改为 - ＆gt;添加（“placeuser”，“整数或文本”，数组（“data”=＆gt; $ username，或来自security.context的$ userid））但我收到错误“无法转换属性路径的值”placeuser“：预期一个数字/字符串。“只有当用户从下拉菜单中选择时，表格才有效。

我的目标是拥有当前登录用户的字段，并在此上下文中添加位置。
万分感谢您的帮助！
