Online calendars are often used in many web applications. Though popular, the logic behind creating a calendar can be scary especially for those who are new to programming. There are many web calendars in the market but some of them are quite complicated. If we are not able to understand the code, it becomes harder for us to customise the calendar to fit into our existing application. As such, we need to create a calendar that can plug itself into any system seamlessly without problems. Whether we are using Wordpress, Mambo/Joomla or Drupal, we should only need to insert one line into our code for the calendar to work. ie something like this:
If you are already bored at this point or not interested to know how to create a web calendar, feel free to see a live demo of the simple calendar here. The installation procedures is in the source code.
Other than configuring the database access for the calendar, I do not want to change other things. With AJAX, I could even make the page static as I navigate between different months in the calendar. In this tutorial, I would like to share with you a simple calendar I created that fufills the objectives discussed above. The tutorial assumes that you have basic knowledge of PHP and SQL but don't worry, the actual code is minimal and you should be able to customise it easily by reading at the comments. I used PHP 4 so that it is compatible with most servers. You should also be able to re-create the calendar easily in other programming languages using the same logic.
