I agree with Russ, don't use a redirect. It is confusing to users, because they won't know what they did wrong.

I usually just take an array of "required" field names and loop through it and any that are blank get added to a scalar that contains an HTML list, like so:

use CGI; my $q = new CGI; my $missed; my @required = qw(name address phone email); for (@required) { $missed .= "<li>$_</li>\n" if $q->param($_) eq ""; } do { print "Content-type: text/html\n\n"; print qq~ You forgot to fill in the following required fields: <ul>$missed</ul> ~; } if $missed;

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.
