Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:
Hi Monks,
I am writing a script to take data from a web page and validate it. Most of the script is done, including the length validation. The only bit i am stuck on as i do not understand perl all that well is the validation of symbols.
The field $username must have either characters i.e 'bob' or characters and digits i.e 'bob1' but not just digits i.e '1234565'. It cannot have any symbols either, only _- are to be accepted i.e for usernames 'bob-jones' or 'tom_frank'.
The current piece of code i have below does not do exactly what i want it to do, but if somebody could modify it, so that i can plonk it back into my script i would be eternaly gratefull.
Thank-you for reading this, and i know for most of you this is simple - but i'm rubbish at this type of thing.if ($display !~ /^\w*$/) { $message = $message.$errmsg ; $found_err = 1 ; }
