                    }
            }

HTML

<form action="hotel2_galery_eventedit.php" method="post" class="col-sm-4" enctype="multipart/form-data">
 <div class="form-group has-info">
                  <label>Event Related images</label>
                  <input type="file" name="images">
                  <input type="hidden" name="image_name" value="<?php echo $val->image_name?>">
                  <input type="hidden" name="image_path" value="<?php echo $val->image_path?>">
                  </div>
                  <button type="submit" class="btn btn-primary">
                  <span>UPDATE</span>
                  </button> 
                            </form>

Your form method is post and you are using as get in php.

Please replace all GET with POST

if(isset($_GET['msg']))

This should be,

if(isset($_POST['msg']))
