Feedback is very valuable to not only the web designers, but to other visitors as well. This tutorial shows you how to create a script that will display comments from users, and allow users to post their own comments. The script is very secure because it converts HTML and Javascript to text. It allows the use of BBCode for user designated formatting.

This script creates a PHP calendar of events that uses an overlib effect to indicate new events--Javascript must be enabled. The script main class myEventsCalendar.php allows you to add multiple events for each day in a year by calling a simple addEvent method. The calendar then shows a preview of the event in an overlib effect as well as a detail page for further information. For this calendar you are going to need a file to test the main class, and also include the required js. Finally, further modifications to the script are possible once you learn how to use the main class, e.g. adding features, integrating the script to a MySql database etc..
