I have a website that loads a CSV, divides it into parts, and shows these parts.
There are 7 parts, and since it is for a music store it is sliced like this:
- the name of the product
- the subname
- the price
- the stock in one shop
- the stock of the other shop
- the group name
- the brandname
What i have now is that it shows 12 products on 1 page, with a next and previous link on top of the page. The pages are made with the group name, every group has it's own page, so you have a drums page, guitar page, speaker page. That all works great. What i programmed in there is a dropdownlist, it drops down a list of brandnames, which should narrow the search for a person who is looking at the products. Problem is right now, that the dropdown menu works, i see the brands, but they are NONE clickable, only the brands that are currently on the page are shown, so NOT all the brands from that group are shown, only the 12 that are currently showing, when you press next, it shows 12 more brands, but i want them to be shown right on the start. And the third problem is, when it is showing the brands, it shows them double or triple, depending on how many products have the same brand. Is there a way what i want, with this code as a basis ?
