The template system has always been one of Joomla's most powerful features, but prior to Joomla 1.5 it was difficult for web design companies to ship templates with much in the way of built-in flexibility. For example, a template available in a variety of different colour schemes would often be supplied as a suite of separate template files. Some web design companies created their own methods for allowing the site administrator to change colour schemes and other template features in the Administrator, but these methods were not standardised and often involved the site administrator in editing configuration files by hand, or installing a custom component to manage the template. This all changed with the advent of Joomla 1.5 which supported the idea of template parameters. Actually it would be more accurate to call them extension parameters as the implementation is generic for all extension types: components, modules, plugins and templates. In this chapter you will learn about how to create and use parameters in your template designs. Each of the wide range of parameter types directly supported by the Joomla Framework is described in detail, but you will also learn how to create your own custom parameter types to suit your particular needs. There is also a short reference on regular expressions as they are used in some of the template parameter types. == Introduction to template parameters == {{:Introduction to template parameters}} == Defining a parameter in templateDetails.xml == {{:Defining a parameter in templateDetails.xml}} == Standard parameter types == {{:Standard parameter types}} ==Standard parameter types in detail== ===Calendar parameter type=== {{:Calendar parameter type}} ===Category parameter type=== {{:Category parameter type}} ===Editors parameter type=== {{:Editors parameter type}} ===Filelist parameter type=== {{:Filelist parameter type}} ===Folderlist parameter type=== {{:Folderlist parameter type}} ===Helpsites parameter type=== {{:Helpsites parameter type}} ===Hidden parameter type=== {{:Hidden parameter type}} ===Imagelist parameter type=== {{:Imagelist parameter type}} ===Languages parameter type=== {{:Languages parameter type}} ===List parameter type=== {{:List parameter type}} ===Menu parameter type=== {{:Menu parameter type}} ===Menuitem parameter type=== {{:Menuitem parameter type}} ===Password parameter type=== {{:Password parameter type}} ===Radio parameter type=== {{:Radio parameter type}} ===Section parameter type=== {{:Section parameter type}} ===Spacer parameter type=== {{:Spacer parameter type}} ===Sql parameter type=== {{:Sql parameter type}} ===Text parameter type=== {{:Text parameter type}} ===Textarea parameter type=== {{:Textarea parameter type}} ===Timezones parameter type=== {{:Timezones parameter type}} ===Usergroup parameter type=== {{:Usergroups parameter type}} == Storing parameter values == {{:Storing parameter values}} == Retrieving parameter data in a template file == {{:Retrieving parameter data in a template file}} == Creating custom XML parameter types == {{:Creating custom XML parameter types}} == Regular expressions in parameter arguments == {{:Regular expressions in parameter arguments}} <noinclude>[[Category:Templates]][[Category:Tutorials]][[Category:Parameters]]</noinclude>
