• Instalation:
    • Download the complete calendar package.
    • Unzip the file.
    • Upload all the files a directory in your server (e.g. "calendar").
    • Open your browser to the calendar directory and run the ac-install.php file.
    • Note - the ac-config.inc.file will need write permissions (chmod 777) - alternatively you can modify it manually on your server.
    • Follow the install instructions. This file preforms the following actions:
      • Check database connection - if it fails, it checks write permission on ac-config.inc.php file then shows a form for indicating your database connection data.
      • Once ac-config.inc.php has been configured, it writes the database tables and default data to the database.
      • Shows basic calendar configuration parameters (url, title, num months etc) - these can later be changed from the administration panel.
    • Once the install process is complete, remove the ac-install.php file from the ftp and change the write permissions on the ac-config.inc.php so that it is unwritable.
    • Login to admin ( eg. http://www.your_url.com/calendar/ac-admin/)
      user: admin
      password: demo
      Note - change these default values as soon as possible!
    • Define your calendar items.
    • Include the calendar in your web or application (see readme.txt for more information).
    • That's all. If you are happy and you like it, feel free to make a donation :)

Important - PHP 8

There is an issue with the script in PHP 8 which is causing the calendar to not display properly.
Here is a quick fix for existing versions (no need to update):

In ac-includes > common.inc.php and change line 16 (latest version) from this: 

//error_reporting(E_ALL ^ E_NOTICE);
to this: 
error_reporting(0);

This code turns off PHP error reporting just for the calendar script.

Version 4

I am currently working a completely new version to adapt the code to more modern development techniques.

Follow the project on Github

See demo version 4

Help with installation?

The calendar script is very simple to set up on your server. However, if you prefer, I can install the calendar on your server for you.
Requirements: I will of course also require ftp access to your server. The cost for this service is 40 Euros * (payable via Paypal) however this may need to be adjusted if you have "special" installation requirements.
If you are interested in this option, don't hesitate to contact me via my contact form. I will get back to you as soon as possible.
