Special character detection on a form....

[quan]

I am trying to detect if the user has entered any characters beside alpha numeric on a form.

This is what i have so far. I dump the form data field into a scalor called $field. Problem is that when I do type in alpha numeric it still thinks it is a special character. Any help is appreciated.

Code so far...


if ($username !~ /^ [a-zA-Z0-9_\-+ \t\/@%]+$/) {
&report_bad_input;
exit;

How about this?

if ($username !~ /^\w+$/) {
&report_bad_input;
exit;
}

What is an example of something you enter that your script reports as bad? If you want strictly alphanumeric then what raider posted is what you should use. Otherwise post an example of what isn't working.
