you should never trust data coming in from a webform. for example, if you are collecting a phone number and the data is in $phoneNumber..
do something like,
$phoneNumber =~ s/.*(\d{3}-\d{3}-\d{4}).*/
or
&handleError() if ( $phoneNumber !~ /^(\d{3}-\d{3}-\d{4})$/ );but, CGI::FormBuilder provides some automatic mechanism for this. it has in built in data types, like phone number. or you can enter custom regular expressions for ones that aren't built in.
