N-Bomb(Nerd) Posted January 7, 2009 Share Posted January 7, 2009 Hello, I've never really been good at filtering user input. I guess I've never really tried to use it so much in fear of getting hacked or something. Anyways, I'm trying to make a script that will take a users input and create a directory on my sever from what they named it. However, how would I be able to run a "check" for all symbols/spaces/quotes? I don't want them to submit it and just have the script create the directory without something they put in the name of it.. so I kind of want it to scan for anything pretty much that isn't alpha-numeric with the exception of underscores. How would one accomplish such thing? Quote Link to comment https://forums.phpfreaks.com/topic/139850-filtering-input/ Share on other sites More sharing options...
premiso Posted January 7, 2009 Share Posted January 7, 2009 preg_match Would be a function you want to look into. I believe there maybe this exact deal somewhere on these forums or on the user comments section at the link to the left. If I knew regex better I would post one, but yea.
