Question

我想更新用户实体（使用唯一的用户ID选择）。

它应该看起来像一个表（宽度= 3个字段），左边是列名（名字，姓氏等），中间是当前值，右边是新值的输入字段

这是我在edit.html.twig中使用div创建的当前表：

<div>
    <div>
        <span></span>
        <span>Current</span>
        <span>Edit here</span>
    </div>
    <div>
        <span>Emailadress:</span>
        <span>{{ userById.getEmail }}</span>
        <span></span>
    </div>
    <div>
        <span>First name:</span>
        <span>{{ userById.getFirstname }}</span>
        <span></span>
    </div>
    <div>
        <span>Last name:</span>
        <span>{{ userById.getLastname }}</span>
        <span></span>
    </div>
</div>

现在出现了问题。在最后一个跨度内，我想要输入字段来编辑值。我尝试使用一个用值填充实体的表单，并将其与名称字段和当前字段组合。

我尝试将一些Editfields插入到下面的Controller函数中，但没有让它工作：（

目前我选择了用户ID并使用它构建表单，将值传递给我的编辑视图。

仅丢失输入字段，显示当前数据正常。以下是我的编辑功能：

public function editUserAction($id, Request $request) {

    $em = $this->getDoctrine()->getManager();
    $userId = $em->getRepository('CompanyUserBundle:User')->find($request->get('id'));


    $form = $this->createForm(new UserForm($request->getSession()), new User(), array(
            'action' => $this->generateUrl('backend_user_management_edit', array('id' => $userId->getId())),
            'em' => $em)
    );
    $form->handleRequest($request);


    $userData = $this->getDoctrine()
        ->getRepository('CompanyUserBundle:User')
        ->findOneById($userId);

    if (!$userData) {
        throw $this->createNotFoundException(
            'No user found for id '.$userId
        );
    }

    return $this->render(
        'CompanyUserBundle:User:edit.html.twig',
        array(
            'form' => $form->createView(),
            'action' => $this->generateUrl('backend_user_management_edit', array('id' => $userId->getId())),
            'userById' => $userId
        )
    );
}

如何添加输入字段以编辑值并使用新值更新当前用户？

亲切的问候

控制器

public function editUserAction($id, Request $request) {

    $em = $this->getDoctrine()->getManager();
    $userId = $request->get('id');
    $user = $this->getDoctrine()
        ->getRepository('CompanyUserBundle:User')
        ->findOneById($userId);

    if (!$userData) {
        throw $this->createNotFoundException(
            'No user found for id '.$userId;
        );
    }

    $form = $this->createForm(new UserForm($request->getSession()), $user, array(
            'action' => $this->generateUrl('backend_user_management_edit', array('id' => $userId->getId())),
            'em' => $em)
    );
    $form->handleRequest($request);

    return $this->render(
        'CompanyUserBundle:User:edit.html.twig',
        array(
            'form' => $form->createView(),
            'action' => $this->generateUrl('backend_user_management_edit', array('id' => $userId->getId())),
            'userId' => $userId,
            'user' => $user
        )
    );
}

查看

{{ form_start(form) }}
<div>
    <div>
        <span></span>
        <span>Current</span>
        <span>Edit here</span>
    </div>
    <div>
        <span>Emailadress:</span>
        <span>{{ user.email }}</span>
        <span>{{ form.email }}</span>
    </div>
    <div>
        <span>First name:</span>
        <span>{{ user.firstname }}</span>
        <span>{{ form.firstname }}</span>
    </div>
    <div>
        <span>Last name:</span>
        <span>{{ user.getLastname }}</span>
        <span>{{ form.lastname }}</span>
    </div>

    <input type="submit" />
</div>
{{ form_end(form) }}
