Joomla! Environment Variables in CSS and Javascript

Here's something I use in templates so that it's easy to apply special styles or effects to certain pages based on the Joomla! environment variables...

$Itemid = JRequest::getInt( 'Itemid', 0 );
$option = JRequest::getCmd( 'option', 'none' );
$view = JRequest::getCmd( 'view', 'none' );
$id = JRequest::getInt( 'id', 0 );

Joomla! Module Administrator Parameters - Multiple Select Lists

Joomla! provides an easy way to add parameters to modules in the administrator control panel. Each module has its own folder inside the modules/ directory. In this directory, an xml file describes the admin control panel parameter options. The file name is modules/mod_YOURMODULENAME/mod_YOURMODULENAME.xml. It's possible to customize these options, create new options, or even create your own custom module, with its own xml parameter file.

The parameters available to you in modules are the ones found in libraries/joomla/html/parameter/element/. The files in this directory all correspond to parameter types you can use in your module xml file. You can also define your own module parameter types, to give you different html list behaviors, or custom data. I recommend packaging these custom elements with the module in the directory modules/mod_YOURMODULENAME/elements/, but you can put them anywhere you want. Perhaps you will have several modules using these resources, in which case you may want to create a system plugin to include your custom library files. In any case, a example of a file in elements/ would look something like this...

Joomla! Module Chrome

Joomla! 1.5 module chrome offers web designers a flexible way to manipulate the output of modules. The built in chrome functions can be found in templates/system/html/modules.php. These functions can be accessed with the tag in your template. For example, the tag has the style "xhtml", so Joomla! will look for the function modChrome_xhtml(), and use this to generate the output for the module.

You can use these functions as a guide, and make your own chrome. To do this, create a file in your template at templates/YOUR_TEMPLATE_NAME/html/modules.php. Any functions you add to this will be available to use in your template. Just make sure you follow the examples for the naming convention, and to know the variables you have available.
