Question

我正在尝试将get变量从anchor href发送到modal。但我似乎无法得到变量$ _GET ['edit2']。当我尝试回显变量时，它会从else语句中获取echo null。提前谢谢

第1部分：用于检查是否已提交get变量。

if(isset($_GET['edit2'])){
        $_SESSION['reply_id'] = $_GET['edit2'];
        $reply_id = $_SESSION['reply_id'];
    }
    else{
        $reply_id = "null";
    }

第2部分：锚点href

<a href='?edit2=". $row2['reply_id'] ."' data-toggle='modal' data-target='#myModal'><small>edit</small></a>

第3部分：模态形式

<div class='modal fade' id='myModal' role='dialog'>
   <div class='modal-dialog'>
      <!-- Modal content-->
         <div class='modal-content row'>
            <div class='col-12'>
               <div class='modal-header'>
                  <h5 class='modal-title'>Edit Reply</h5>
                  <button type='button' class='close' data-dismiss='modal'>&times;</button>
               </div>
               <div class='modal-body'>
                  <form id='r_edit_form' method='post'>
                     <div class='row'>
                        <label class='col-12'>Reply :</label>
                     </div>
                     <div class='row'>
                       <textarea class='col-12' form='r_edit_form' name='description' rows='4'>". $reply_id ."</textarea>
                     </div>
                     <div class='row'>
                       <input class='col-12 btn btn-dark' type='submit' name='edit_reply'>
                     </div>
                  </form>
                </div>
                <div class='modal-footer'>
                  <button type='button' class='btn btn-default' data-dismiss='modal'>Close</button>
                </div>
              </div>
            </div>
          </div>
        </div>
