Symfony Formbuilder get pathInfo

Question

有沒有辦法在buildForm函數內返回頁面的pathInfo或URL？

class RoomType extends AbstractType 
{ 
    /** 
    * {@inheritdoc} 
    */ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
{ 

VarDumper::dump($builder->getRequestHandler()); 

Answer 1

只有您有請求對象。一種選擇是在構建表單時傳遞請求。

你的控制器動作

$form = $this->createForm(new RoomType($request), new Room()); 

你的表單類型級

class RoomType extends AbstractType 
{ 
    protected $request; 

    public function __construct(Request $request) { 
     $this->request = $request; 
    } 

    /** 
    * {@inheritdoc} 
    */ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     VarDumper::dump($this->request); 
    } 
}
