因此，我试图在不为表单创建类的情况下将一种表单嵌入到另一种表单中。这是我得到的

    $form = $this
        ->buildForm('UserAlert', $alert)
        ->add('Alert', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Alert', 'property' => 'name', 'required' => true))
        ->add('Site', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Site', 'property' => 'name', 'required' => false))
        ->add('Keyword', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Keyword', 'property' => 'name', 'required' => false))
        ->add('Variant', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Variant', 'property' => 'name', 'required' => false))
        ->add('Name', 'text');


    $uac = $alert->getUserAlertConfig();
    $subform = $this
        ->buildForm('UserAlertConfig', $uac)
        ->add('EmailAlert', 'choice', array('choices' => array('1' => 'Yes', '0' => 'No'), 'required' => true, 'label' => 'Email Alerts'))
        ->add('EmailHours', 'text', array('required' => false, 'label' => 'Email Alert Hours'))
        ->add('TextAlert', 'choice', array('choices' => array('1' => 'Yes', '0' => 'No'), 'required' => true, 'label' => 'Text Alerts'))
        ->add('TextHours', 'text', array('required' => false, 'label' => 'Text Alert Hours'));

    $form->add($subform);
    $form = $form->getForm();

但是，在 getForm() 函数上，它是这样说的

Neither property "form" nor method "getForm()" nor method "isForm()" exists in class "Blah\MgmtBundle\Entity\UserAlert"

有人知道我应该如何使用快速加载的东西让它工作吗？

这里是buildForm

public function buildForm($model = '', $data)
{
    if (empty($model)) {
        throw new \Exception("Must define a model");
    }
    return $this->get('form.factory')->createBuilder('form', $data, array('data_class' => "\\Blah\\MgmtBundle\\Entity\\$model"));
}

最佳答案

最终为子表单创建了一个界面并像这样添加了它

    $form = $this
        ->buildForm('UserAlert', $alert)
        ->add('Alert', 'entity', array('class' => 'Neokeo\MgmtBundle\Entity\Alert', 'property' => 'name', 'required' => true))
        ->add('Site', 'entity', array('class' => 'Neokeo\MgmtBundle\Entity\Site', 'property' => 'name', 'required' => false))
        ->add('Keyword', 'entity', array('class' => 'Neokeo\MgmtBundle\Entity\Keyword', 'property' => 'name', 'required' => false))
        ->add('Variant', 'entity', array('class' => 'Neokeo\MgmtBundle\Entity\Variant', 'property' => 'name', 'required' => false))
        ->add('Name', 'text');

    $uac = $alert->getUserAlertConfig();



    $subform = $this->buildForm('UserAlertConfig', $uac, new \Neokeo\MgmtBundle\Form\UserAlertConfig)
        ->add('EmailAlert', 'choice', array('choices' => array('0' => 'No', '1' => 'Yes'), 'required' => true, 'label' => 'Email Alerts'))
        ->add('TextAlert', 'choice', array('choices' => array('0' => 'No', '1' => 'Yes'), 'required' => true, 'label' => 'Text Alerts'));

    $form->add($subform, '', array('label' => ''));
    $form = $form->getForm();

如果有人能在不创建接口(interface)的情况下找到更简单的方法，请告诉我

关于php - Symfony2 子表单，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6444872/
