Stripslashes Help
 

Hello! I know that I've asked this before, and I know I've been HELPED before, but it's frustrating searching for it. I cannot find it and I've tried doing it myself but I'm failing miserably! :coloness:

How do you enter the stripslashes command into certain places? I've managed to do the user bio as I found Kyttias' post from before but I cannot find anywhere else. The places I want to input it are:

Bio's (done)
Visitor messages
PM's (not sure if this is a problem, yet, but just in case)
Both item and adopt shops

And anywhere else people have noticed problems..... thanks for the help. Sorry I couldn't find it myself! If someone helps me I'm bookmarking this page!!!!! >.<

Also, how do you stop people signing up with apostrophes in their name? I want to make it so that they need to use letters a-z or 0-9. I have no members on the site at the moment, while I sort things out, and would like to stop that happening before it does like last time!! XD

Thanks for all your help
