Smarty Global Variables used in Modules

[ArtAche]

Hi guys,

 

So, I'm a (very) amateur, self taught web developer, trying to learn how to use Smarty variables. I've read a lot on online, but I'm having trouble getting an 'Request a Quote' module to use the global Prestashop variable '$come_from' (which requests the previous page's url).

 

Please help me?

 

UPDATE: I just got it to work, but still have a problem. $come_from is showing the current address url isntead of the address of the product page that directed it there. You can see by going to my site (http://www.utopiascreenprinting.com.au/) and using the 'Request a Quote' button on any of our products. Why's it doing this and can I fix it?

 

Advice?

 

Cheers guys!

Just to be clear, my motivation here is to grab the url so that I can retain the information about what product attributes are selected in the side bar. Does anyone know if the product attribute selection creates a Smarty variable that carries over to the shopping cart? Perhaps a variable that I could use in my quote form...?
