[sf-perl] Design help needed with DELETE check box loop

[frosty]

Ken, this list is not your personal help desk.  Most of us, newbies and experts alike, have busy lives and contribute to the list as time allows.  If you need on-demand application design services, there are people you can hire to do that for you.

It sounds like you're trying to figure out how to write a simple Web application in Perl.  This is not only possible, it's quite practical; much of the Web is built on Perl and there are many ways to go about it.

For starters, you should read about Perl's CGI module:

http://perldoc.perl.org/CGI.html

You will also need to talk to your database if you want to bulk-delete anything, and for that you will need the Perl DBI, or something higher-level that uses it:

http://search.cpan.org/~timb/DBI-1.602/DBI.pm

At this point it gets more complicated, since you will have to know a bit about databases in order for anything to work.  You (or your sysadmin) may need to install the DBI module and the drivers for your system.

As you move forward, you should consider working with a framework that does some of the work for you, like HTML::Mason or Catalyst MVC.

http://catalyst.perl.org/

Catalyst in particular may be a good choice for a beginner as it really does a *lot* of the work for you.

I also recommend reading a good introductory Perl book, like "Learning Perl" from O'Reilly:

http://www.oreilly.com/catalog/lperl3/

Once you have read that book and poked around a little, you will be able to ask more specific questions from this list and also on perlmonks, which is another great place to get help:

Good luck.
