An important part of building modules is dealing with module settings. We can define custom parameters for modules in the module XML manifest file. Module parameters fall into two groups, Module Parameters and Advanced Parameters.
There is no difference in the application of Module Parameters and Advanced Parameters; we split them into two groups to help the classification of the parameters, consequently making the administrator’s job easier.
As a general rule: Module Parameters are the more basic, although generally more fundamental, of the two. Advanced Parameters pertain to settings that are more complex and are rarely modified.
This example shows how we can add some simple parameters to a module:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE install SYSTEM "http://dev.joomla.org/xml/1.5/module-
install.dtd">
<install version="1.5" type="module" client="site">
<name>My Extension</name...
