I'm working this whole weekend to rewrite/move an old custom made shop extension to the new shop.

The amount of possible SQL injections is too damn high and this piece of shit the creator calls code is the most pitiable thing I have ever seen!
I don't how you can call yourself an experienced programmer if you create SQL queries by concatenating strings and variables in raw PHP, copying the same fucking includefiles to 10 different folders and use all of them in random places.

I'm not angry at all, I just want to castrate you with a blunt, fake swiss army knife so mankind is safe from you multiplying yourself.
