Managing Hierarchical Data in MySQL
If you are using this way Nested Set Model to manage hierarchical data in MySQL tree.class.php will help you with it using this class you can easy to:
- add new node
- update node
- delete node
- move branch
- sort tree
Also there are some methods to build html pull down menu and html bulleted list to build DHTML menu and tree I’m using this way http://www.brightsoftsolutions.com/article-prototype-js-based-dhtml-menu.php it’s just simple example:)




The sort order doesn’t seem to save. Can you verify the script works for you?
