Calling a perl script and passing parameters from html

HannibalRex has asked for the wisdom of the Perl Monks concerning the following question:

So I have a perl script that someone else wrote, accepts command line parameters to run, I'm trying to "web enable" this script. The way I think of it is a form submit/post to the script, and the script accepts the values passed to it from entries on the web page. For example, this script creates a given number of random numbers based on a seed, so on the cmd lind it looks like ./numgen.pl --numcards=10000 --seed=25 --blurb="10000 cards for JoMama" Can someone point me to a reference on how to do this? I've been told it would be best to do it in Python and use a system call, which I honestly have no idea how to do. So, I'd really like to know how to do this, not just hack it. I'm really needing a push in how to do this, and where a good reference may be located. Everything I keep googling just seems too complicated, or not really what I am looking for. Is it not common to use a web interface to do sys or db activities through perl? Sorry, I'm an old C guy, so I don't really understand the web parts of perl and or python yet. TIA!

If the script doesn't take too long to execute and you do not need to process it's results then a wrapper script like this should be enough to get you up and running: `use strict; use CGI; use CGI; my $q = new CGI; @ARGV = (); foreach ($q->param()) { $value = $q->param($_); $value =~ s/"/\\"/g; push @ARGV, "--" . $_ . '="' . $value . '"'; } do 'path/to/the/script.pl';` [download] All it does is it moves the parameters from the querystring or post into the @ARGV array (array of script parameters) in the format required by the script and then executes the script without starting a new process. As long as the script prints its results to STDOUT they should be sent to the client browser. Jenda Enoch was right! Enjoy the last years of Rome.	[reply] [d/l]
