[SOLVED] Help with regex?

[darkfreaks]

i know this is for PHP regex but im trying to mod jquery regex i am sure its really all the same.

 

however i need the file to only allow underscores and dashes and subtract for any other special character used besides that.

I'm not certain I'm understanding you correctly. Do you mean you wish to allow alphanumerics and _ and - only? If so you could do something like...

 

"/^[0-9A-Za-z_-]*$/"

[darkfreaks]

i changed characters to allow - and _ only but when i upload it and when it tells me i have a medium password to enter special characters then i enter a $^&* it jsut suddenly goes up to 100 percent pass.
