With the new Joomla! 2.5 out, it was time to upgrade my Joomla! 1.7 installation. You have the option to upgrade with a single click but before you do press the button, I advise you to try it on a local copy of your website. It was a smart move to follow when I did the upgrade, after which I was confronted with the scary HTTP 500 (Internal Server Error) message in Google Chrome, whereas in Firefox I get an empty screen.

If we are designing our own templates in Joomla we are already using some of the php programming language. Apart from including our modules, components, scripts and css files, we can use php code to further extend the website. The following code should be placed in your template index.php file. It was tested on the new Joomla 2.5 beta and Joomla 1.7.3 system.

Sometimes we need to change the display of Joomla articles and categories. Creating different layouts for articles and categories is almost identical to creating alternative module layouts. The use of layouts is more practical from the use of template overrides if we need to have more than one different layout presentation of our content.

In Joomla 1.6 and 1.7 we have the option to use several different alternative layouts for individual styling. Alternative layouts differ from standard Joomla overrides in that, you can have unlimited alternative layout files. We also use different naming conventions and we must enable the layout in the Alternative Layout option field.
