Question

我目前在Symfony中有一个脚本，我在控制器中生成一个表单。此表单显示实体“页面”的内容。如果用户编辑表单并提交表单，则表单会调整数据库中的相应数据。

  /**
 * Webpage allowing user to edit a page and her attributes
 *
 * @Route("/edit")
 */
public function editAction(Request $request)
{
    /*
     * Get an array of all the current pages stored in the database.
     *
     * foreach loop through each website and create a seperate form for them
     *
     */
    $em = $this->getDoctrine()->getManager();
    $pages = $em->getRepository(Page::class)->findAll();


    foreach ($pages as $page) {
        $editform= $this->createFormBuilder($page)
            ->add('name', 'text')
            ->add('location', 'url')
            ->add('displayTime', 'integer')
            ->add('save', 'submit', array(
            'label' => 'Edit page'
        ))

            ->getForm();

        $editform->handleRequest($request);

        if ($editform->isValid()) {
            $em = $this->getDoctrine()->getManager();

            $em->flush();
            return new Response('Page edited successfully - immediately effective');
        }

    }



    return $this->render('WalldisplayBundle:Walldisplay:edit.html.twig',
        array(
            'editform' => $editform->createView()
        ));
}

不幸的是，这只会打印一个包含数据库中最后一个条目的表单。我想要的是为数据库中的--every-条目创建一个表单，而不仅仅是最后一个。我试过迭代Doctrine存储库，但没有运气。我怎么能解决这个问题？

也许它会奏效。我没有测试过。

/**
 * Webpage allowing user to edit a page and her attributes
 *
 * @Route("/edit")
 */
public function editAction(Request $request)
{
    /*
     * Get an array of all the current pages stored in the database.
     *
     * foreach loop through each website and create a seperate form for them
     *
     */
    $em = $this->getDoctrine()->getManager();
    $pages = $em->getRepository(Page::class)->findAll();


    foreach ($pages as $key=>$page) {
        $editforms[$key] = $this->createFormBuilder($page)
            ->add('name', 'text')
            ->add('location', 'url')
            ->add('displayTime', 'integer')
            ->add('save', 'submit', array(
            'label' => 'Edit page'
        ))

            ->getForm();

        foreach($editforms as $editform){
            $editform->handleRequest($request);

            if ($editform->isValid()) {
            $em = $this->getDoctrine()->getManager();

            $em->flush();

        }

        }

        return new Response('Page edited successfully - immediately effective');


    }

    foreach($editforms as $editform){
            $editform->handleRequest($request);

            if ($editform->isValid()) {
            $em = $this->getDoctrine()->getManager();

            $em->flush();

    }
    foreach($editforms as $editform){
        $arrayForm[$editform] = $editform->createView();   
    }
    return $this->render('WalldisplayBundle:Walldisplay:edit.html.twig', $arrayForm);
}

打印所有Symfony2表单
