Perl subroutine from a webpage?

[wjbarton]

Hi there. Can a specific subroutine from a Perl script be launched from a web page or form action? I know how to launch a perl script, but is there some syntax to start with a particular subroutine, maybe something in html like:

<form name="myForm" method="post" action="myPerl?starthere">

That's just a guess, but hopefully it will explain what I'm looking for.

Thanks!

Yes, you have the right idea. What you have to do is access the $ENV{'QUERY_STRING'} environment variable. This variable contains what you have put after the? in the action property of your form tag.

Your code would look something like this:

$command = $ENV{'QUERY_STRING'};
&someSubroutine if $command eq "foo";
&someOtherSubroutine if $command eq "bar";

Alternatively, you could even execute a different subroutine based on the contents of a hidden or non-hidden form field.

Dude you rock. I used the hidden input field named "Update" and created an "if (!($input{Update})) {}" logic area in my perl script. Nice!

Thanks man,
