Symfony 2.3表单没有将所有字段传递给formView

标签： php forms symfony doctrine-orm twig

我希望有人可以帮我调试我遇到的问题，表单字段没有传递到Symfony 2.3中的表单视图。

我有一张我正在制作的表格，这是我几个月前制作的。表单工作正常，直到我决定添加几个字段。我将字段添加到实体并更新数据库架构没有问题。我将字段添加到表单类型类，然后将它们添加到树枝模板中。

这就是问题出现的地方，我不断收到错误说

Method "adminFromEmail" for object "Symfony\Component\Form\FormView" does not exist in SaveAdminBundle:System:systemsettings.html.twig at line 38

所以我开始做一些挖掘。我做了表格的dump()，得到了以下回复：

$form变量转储

但是，当我在调用$form->createView()后转储视图时，我得到了这个：

          ["userRegistrationEmail"]=> string(31) "Symfony\Component\Form\FormView"

          ["resetUrl"]=> string(31) "Symfony\Component\Form\FormView" 
          ["clientRegistrationEmailAdminCopy"]=> string(31) "Symfony\Component\Form\FormView" 
          ["clientLoginUrl"]=> string(31) "Symfony\Component\Form\FormView"

          ["_token"]=> string(31) "Symfony\Component\Form\FormView" } 
          ["rendered"]=> bool(false) 
       }

如果仔细查看这两个打印输出，您可以看到adminFromEmail和adminFromName在转储$form变量时出现，但在调用$form->createView()之后却没有出现我不知道为什么。

我包含与此相关的文件的相关区域。

表格类：

class SystemSettingType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        ...
        ->add('adminFromEmail', 'text') 
        ->add('adminFromName', 'text')
        ...
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver) 
    {
        $resolver->setDefaults(array(
            'data_class' => 'Save\AdminBuildle\Entity\SystemSettings'
        ));
    }

    public function getName()
    {
        return 'systemsettings';
    }
}

实体：

class SystemSettings
{
    ...

    /**
     * @var string
     * 
     * @ORM\Column(name="system_from_email", type="string", length=100)
     */
     private $adminFromEmail;

    /**
     * @var string
     * 
     * @ORM\Column(name="system_from_name", type="string", length=100)
     */
     private $adminFromName;

     ...
 }

注意： getter和setter都在Entity中正确形成（通过运行doctrine:generate:entities创建）

控制器：

public function listSystemSettingsAction(Request $request)
{
    $em = $this->getDoctrine()->getManager();
    $system_setting = $em->getRepository('SaveAdminBundle:SystemSettings')->find(1);
    if(is_null($system_setting)){
        $system_setting = new SystemSettings();
    }
    $form = $this->createForm(new SystemSettingsType(), $system_setting);

    $form->handleRequest($request);

    if($form->isValid() ){
        $em->persist($system_setting);
        $em->flush();
    }

    return $this->render('SaveAdminBundle:System:systemsettings.html.twig', array('form'=>$form->createView()));
}

树枝模板：

...
{% block body %}
<div class="tabbed-box">
    <h1>System Settings</h1>
       <div class="tabbed-area">
           <ul class="tabs">
               <li><a href="#" class="tab active" id="tab_1" title="content_1">System Settings</a></li>
           </ul>
           <div class="content" id="content_1">
               {{ form_start(form) }}
               <fieldset>
                   <legend>System Settings</legend>
                   <ul class="form-fields">

                       ...

                       <li>
                           {{ form_row(form.adminFromEmail) }}                       
                       </li>
                       <li>
                           {{ form_row(form.adminFromName) }}
                       </li>

                       ...

                 </ul>
             </fieldset>
             <div class="button-bar">
                 {{ form_widget(form.updateSettings) }}
             </div>
         {{ form_end(form) }}
     </div>
</div>
...

如果有人知道为什么表单字段不会传递到表单视图，请告诉我。

答案 0 :(得分：0)

对我来说，看起来像是一个明确的缓存问题，或者你可能缺少实体的use语句。代码对我来说是正确的。
