displaying duplicate items

Post by littlebeagle »

Hi,
I'm trying to help a friend with a shopping cart (Shop-Script Premium), and on the main page, it is supposed to show 4 random products. The problem is that it displays duplicates sometimes (same product side by side). Can anyone tell me how to fix this?

His site is:

Thanks.

We can't really help without seeing the code that is generating the random items.

The community has yet to acquire the ability to read minds, and guess each others code.

Sorry, I wasn't sure if it was something someone would just *know* or could figure out by 'View Source' in the browser. I'm not a PHP person myself. :D

Here is the code I think you need. If not, then please let me know.

(the 4 products being shown are referenced as "special offers" in the shopping cart.)

Thanks so much for your help.

Code: Select all
