同类型的多种形式 - Symfony 2 [英] Multiple forms of same type - Symfony 2

问题描述

所以我的控制器动作与此类似

So I have my controller action similar to this

$task1 = new Task();
$form1 = $this->createForm(new MyForm(), $task1);

$task2 = new Task();
$form2 = $this->createForm(new MyForm(), $task2);

假设我的 MyForm 有两个字段

And let's say my MyForm has two fields

//...
$builder->add('name', 'text');
$builder->add('note', 'text');
//...

这两个表单似乎是同一个类型的 MyForm，当在视图中呈现时，它们的字段具有相同的名称和 ID(两个表单的名称"字段共享相同的名称和 ID；同样对于注释"字段)，因此 Symfony 可能无法正确绑定表单数据.有谁知道有什么解决办法吗?

It seems like since the two forms are of the same type MyForm, when rendered in the views, their fields have the same name and IDs (the 'name' fields of two forms share the same name and id; the same goes for the 'note' fields), because of which Symfony may not bind the forms' data correctly. Does anyone know any solution to this?

推荐答案

// your form type
class myType extends AbstractType
{
   private $name = 'default_name';
   ...
   //builder and so on
   ...
   public function getName(){
       return $this->name;
   }

   public function setName($name){
       $this->name = $name;
   }

   // or alternativ you can set it via constructor (warning this is only a guess)

  public function __constructor($formname)
  {
      $this->name = $formname;
      parent::__construct();
  }

}

// you controller

$entity  = new Entity();
$request = $this->getRequest();

$formType = new myType(); 
$formType->setName('foobar');
// or new myType('foobar'); if you set it in the constructor

$form    = $this->createForm($formtype, $entity);

现在您应该能够为您创建的表单的每个实例设置不同的 id.. 这应该导致 <input type="text" id="foobar_field_0" name="foobar[field]" required="required> 等等.

now you should be able to set a different id for each instance of the form you crate.. this should result in <input type="text" id="foobar_field_0" name="foobar[field]" required="required> and so on.
