In this post i will explain to how to create a Drag and Drop Menus in your web application using php and mysql. This script allows you to manage your menu using drag and drop elements to create a page hierarchy on your webpage. We connect these events using Jquery & Ajax functionalities to update the menu structures.
I am using PDO ( PHP Data Objects) in this example. By using PDO you will take advantage of native prepared statement present in MySQL 4.1 and higher versions. If you’re using an older version of mysql client libraries, PDO will emulate them for you.
Database connection file config.php
