如何在控制器中获取具有相同名称的多个复选框元素的值

Question

我的twig文件中有以下代码:

<form method ="POST" action="{{path('deleteMessages')}}">
                {% for message in pmReceived %}
                    {% if message.isread == false  %}
                        {% if message.showincoming == true  %}
                            <div class="border">
                                <div  class="pmbox">
                                    <p class="pmsender">{{message.sender}}</p><p class="pmdate">{{message.date|date('d-m-Y H:i:s') }}</p><p class="pmsubject">{{message.subject}}</p><input type="checkbox" name="deletePm" value="{{message.pmid}}">
                                </div>
                                <div class="pmcontents">
                                    <p class="titleContent">Contents:</p>
                                    <p>{{message.contents}}</p>
                                </div>
                            </div>
                        {% endif %}
                    {% endif %}
                {% endfor %}
                {% for message in pmReceived %}
                    {% if message.isread == true %}
                        {% if message.showincoming == true  %}
                            <div class="border">
                                <div class="pmbox">
                                    <p class="pmsender">{{message.sender}}</p><p class="pmdate">{{message.date|date('d-m-Y H:i:s') }}</p><p class="pmsubject">{{message.subject}}</p><input type="checkbox" name="deletePm" value="{{message.pmid}}">
                                </div>
                                <div class="pmcontents">
                                    <p class="titleContent">Contents:</p>
                                    <p>{{message.contents}}</p>
                                </div>
                            </div>
                        {% endif %}
                    {% endif %}
                {% endfor %}
                <button class="deleteButton" type="submit">Delete selected messages</button>
            </form>

这是我的控制器代码:

public function deleteMessagesAction(Request $request) {
    if (false === $this->get('security.context')->isGranted('IS_AUTHENTICATED_FULLY')) {
        throw $this->createAccessDeniedException('Unable to access this page!');
    }

    $em = $this->getDoctrine()->getEntityManager();
    $pm = $this->getDoctrine()
            ->getRepository('LoginLoginBundle:Privatemessage')
            ->findBypmid($request->get('sentValue'));
    $deleteMessages = $request->get('deletePm');
    var_dump($deleteMessages);

    $user = $this->get('security.context')->getToken()->getUser();
    $pmReceived = $this->getDoctrine()
            ->getRepository('LoginLoginBundle:Privatemessage')
            ->findByReceiver($user->getUsername());

    $pmSent = $this->getDoctrine()
            ->getRepository('LoginLoginBundle:Privatemessage')
            ->findBySender($user->getUsername());

    return $this->render('LoginLoginBundle:Default:pmPage.html.twig', array('pmReceived' => $pmReceived, 'pmSent' => $pmSent, 'toDelete'=>$deleteMessages));

}

现在我想得到所有'勾选'复选框的值,我认为$ deleteMessages将是一个值数组,但它只保留勾选的最后一个复选框.

如何获取控制器中所有值的数组？

Answer 1

您需要更改输入的名称.这样你就会收到一系列已选中的复选框,而不是只收到最后一个选中的复选框:

<input type="checkbox" name="deletePm[]" value="{{message.pmid}}">

这将导致数组等于:

   [
        0  => 1,
        1  => 10,
        2  => ...,
   ]

然后你可以循环这个数组来相应地删除:

$deleteMessages = $request->get('deletePm');
foreach($deleteMessages  as $deleteMessageId) {
    //Do something with the ID
}
