PHP - Regular Expression

Drazhar

I am using preg-match to check and see if a name entered is any combination of letters, numbers, hyphens and underscores

[PHP]preg_match("/[a-zA-Z0-9\-\_]+/", $name)[/PHP]

where am i going wrong?

What's the error you're getting?

Drazhar

no error, it just doesnt work

i use it in an if statement. so if name is hello9_9, it will enter the if statement, but if it was hello9_* (or any other character not a letter, number, - or _) then it goes to the else bit

Could you post all the code please. I'll have a look.

Is this what it should do, or what it does do right now?

I'm guessing that you want to make sure the input only contains these characters, in which case just change your regular expression to
"/^[a-zA-Z0-9\-\_]+$/"
