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 $username must have either characters i.e 'bob' or characters and digits i.e 'bob1' but not just digits i.e '1234565'. It cannot have any symbols either, only _- are to be accepted i.e for usernames 'bob-jones' or 'tom_frank'. The current piece of code i have below does not do exactly what i want it to do, but if somebody could modify it, so that i can plonk it back into my script i would be eternaly gratefull.
if ($display !~ /^\w*$/) { $message = $message.$errmsg ; $found_err = 1 ; }
Thank-you for reading this, and i know for most of you this is simple - but i'm rubbish at this type of thing.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
