Search in multiple categories with checkboxes

[mat22]

Hello!

So I got problem with my search on browse.php. I'm trying to make it so you can check multiple categories and then search for torrents in them. Problem is - it works when I enter link manually but when I check them and then write what I'm searching for it just doesn't work and it searches in all categories. I have default code for search so maybe someone can be so kind and give a working script for this?

I can give you my browse.php but not full address since it's under development.

I know the code needs a bit of cleaning but I just want to get this search to work and then I'll work on other things.
