i want user update message content above on button click. order not coming db.

how allow user edit of text data except orderid?

you can request content @ file in same directory called xyz.php

with jquery

$.ajax({     url: 'xyz.php',     type: 'get',     success: function(data){         $('#container').html(data)     } }) 

the php file outputs text

<?php  echo "<strong>yo</strong>"; 

maybe idea
