Passing a variable in a url

[ToysStore]

I want to change the layout of a page by passing a variable within the url.

For example if i send the url http://localhost/prestashop/?home1 then the global.css must be loaded.

If is send http://localhost/prestashop/?home2 then the global_extra.css must be loaded.

Can somebody explain to me how to pick up the ?home variable within the tpl file to change the css.
I know this can be done because the prestateam did the trick on www.natarianni.fr (notice the tabs in the header)

Regards, Martin

If I understand you correctly, you want to have a site that calls for more than 1 css.

If you are using the site that you are talking about as an example, There are two ways to do this:

#1) The easy way--it is using one category, two sub-categories and a filter. The filer will restrict certain items to pass along the value to each sub category. And each sub-categories uses different css.

#2) Difficult way--Group the elements and use a html template. Use the header menu to call for different css with different category.

I have test tried both ways, and they work.
