如何在ajax调用中将数组传递给控制器​​并使用Symfony3返回

Question

Hi and thanks for helping me, I have a ajax call with data I would like to send to the Controller so I can delete the specified data at a later time. For the moment I would like to show the given javascript from the controller. Sorry in advance for my English, it's not my first language.

It's currently returning a JsonResponse to test if the method is called but I want to return the given javascript array (playlogs) instead, how can I do that?

Javascript:

<script type="text/javascript">
       $(document).ready(function () {
           $('#deleteBtn').click(function () {
               var playlogs = [];

               $.each($("input[name='playlog']:checked"), function () {
                   playlogs.push($(this).val());
               });
               var confirmText = "Are you sure you want to delete this?";
               if (confirm(confirmText)) {
                   $.ajax({
                       type: "delete",
                       url: '{{ path('playlog_delete_bulk') }}',
                       data: playlogs,
                       success: function () {
                           alert("selected playlogs: " + playlogs.join(", "));
                       },
                   });
               }
               return false;
           });

       });
   </script>

deleteBulkAction in PlayLogController:

/**
 * @Route("/delete/bulk", name="playlog_delete_bulk")
 */
public function deleteBulkAction(Request $request)
{
    if ($request->isXMLHttpRequest()) {
        return new JsonResponse(array('data' => 'Successfully called the named route playlog_delete_bulk  '));
    }

    return new Response('This is not ajax!', 400);
}

Answer 1

Use 'request' ParameterBag to access POST, PUT, PATCH, and DELETE data

  $password = $request->request->get('password');

and 'query' - for GET data

  $pageNumber = $request->query->get('page');

Answer 2

You can send playlogs as json (or any other format, depends on data). Read request body by $request->getContent() and decode it in php array.

Ex.:

<script type="text/javascript">
   $(document).ready(function () {
       $('#deleteBtn').click(function () {
           var playlogs = [];
           $.each($("input[name='playlog']:checked"), function () {
               playlogs.push($(this).val());
           });

           var confirmText = "Are you sure you want to delete this?";

           if (confirm(confirmText)) {
               $.ajax({
                   type: "delete",
                   url: '{{ path('playlog_delete_bulk') }}',
                   data: JSON.stringify(playlogs),
                   success: function (data) {
                      alert("selected playlogs: " + data.join(", "));
                   }
               });
           }
           return false;
       });

   });

/**
 * @Route("/delete/bulk", name="playlog_delete_bulk")
 */
public function deleteBulkAction(Request $request)
{
    if ($request->isXMLHttpRequest()) {
        return new JsonResponse(json_decode($request->getContent()));
    }

    return new Response('This is not ajax!', 400);
}
