Off the top of my head, without looking at how we do it, there is a simple answer.

On the form place a hidden variable, and check for its value with the script. If it's set to value X to action Y. This way a single script can perform multiple functions.

While I'm not saying this is the most efficient code, it does work. (I did bother to look it up)

$CGI = new CGI;
my($item) = $CGI->param('item');
my($add) = $CGI->param('add');
my($sql, $sth, $comments) = ("", "", "");

if(defined($add)) {
[download]

Process the form

} else {
[download]

Show the form

• 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).
