In addition to Ovid's excellent advice, I'd also like to recomment checking out the Data::FormValidator module on CPAN. It provides a number of simple methods to validate the parameters sent to you from the browser. Are the fields required or optional? Do you just want to see if anything at all was entered into them, or do you want fine grained control over what was entered? It lets you choose all of that. Here is an example of how you might use it:
Hopefully, that gives you a decent example of how it might work. Be sure to read the docs, they give lots of examples. Good luck!
