How to write a proper shop page?

[parayna]

Can someone please help me write a proper shop page? I want to create a custom page that I make myself as that is the only way to get the placement I want for the shopkeepers (I don't know how to do it in the default shop files). So I guess I would like to ask if someone can help me write 'get' and 'getview' pages for items.. and where it deducts the price of the item from their inventory and they can also choose the quantity at some point.

The reason I want this is so that I can have a shopkeeper and then images of items underneath, and when they click the image it takes them to another page where they can maybe select the quantity? They then click buy and it deducts the money set by me in the adminCP and adds it to their inventory..

Kyttias was kind enough to help me with doing this for adoptables so I have included them in spoilers in case anyone wants help with the structure.. sorry for asking but I have already tried what I can think of and it hasn't worked >.< Thank you... I really want to get my shops up and running for my beta testers XD

They are both seperate files so I guess items would need to be called getitem and getitemview? Or something like that XD Thanks if someone helps me... this has stumped me for days >.<

(It would also be nice if someone could help me with the 'adopt' shops. Or would it still be the same file? And you just put in their adoptable id? It's just I may not want all of my pets up for free, like they are from the adoptable page at the moment)
