             $pww = "123";
             if ($pin!=$pww) {
               echo "WRONG PIN.. TRY AGAIN..";
             }
             else{
                header('Location: myorders.php');
             }
          } // SUBMIT 
          ?>
        </form>
      </div>

根據我的評論，從您的提交按鈕中刪除data-dismiss="modal" 。 data-dismiss="modal"用於關閉模式對話框。 你已經在這里了

<button type="button" class="close" data-dismiss="modal">&times;</button>
