Today I prepared new interesting article - I will tell how you can create own commenting system (AJAX) for your items (any units at your website) with PHP. For our demonstration - I prepared two SQL tables: first table will keep records of our items. It contain several fields: title, description, time of adding and comments count. Another table will keep records of comments. We will use jQuery too (for better interface behavior). One of features will spam protection (we can post no more than one comment every 10 minutes)!

The tutorial includes all of the code, markup and styling you'll need to make the system work. If you'd like to get right into the code you can download it as a package or you can try out their demo.

I just release Zip-1.4.0. This release adds support for all kind of comments, read or write. One bug has been fixed, Windows users may had problems to add files to an existing archives. Thanks to Irokez (pear's OpenDocument project for SoC) to have catched it.

He also includes a brief code example of the commenting functionality.
