从symfony的树枝表单中获取已检查的值

Question

我创建了一个用户过滤器表单，结果将其显示为复选框，但我想让用户选中以向其发送SMS。 我的问题在于检查值的恢复步骤

感谢您的帮助。

我创建了一个发送SMS的功能，但是我必须将复选框中选中的用户的电话号码作为参数传递给他。

树枝文件：

  <div class="box-body">
                <form method="POST" action="{{ path('ce_utilisateur_send_sms') }}" id="lbad_form_sms" name="users">
                <div class="table-responsive">

                    <table id="tableuser"
                           class="table table-bordered table-striped table-hover dt-responsive display nowrap"
                           cellspacing="0">

我的函数sendSms

    public function sendSmsAction(Request $request, SmsProvider 
    $provider)
    {

        $users = $request->get('allusers')->getData();
        var_dump($users);
        die();//returns null, I do not know how to get that in a twig 
        form to pass it in the second form (smsFormType)

        $form = $this->createForm(smsFormType::class);
        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            $message = $form->get('message')->getData();
            $objet = $form->get('objet')->getData();
            $provider->sendMessage($message, $object, $phonenumbers);


        }
    }
