Parse html form inputs into csv

I would like to have an HTML form with, say, five boxes and a 'submit' button. Submitting will give the contents of the five boxes to a perl script (NMS distro of FormMail.pl) as a comma-separated list. With the limited extent of my knowledge, I have no idea how to accomplish this. I'd imagine some sort of intermediate parsing script?

Thanks!

::edit:: For now I've settled on inlining some javascript that gets called onSubmit for both input validation and the parsing of the CSV. Am I correct in assuming that there is no HTML-native way to do these things?

The only HTML-native way is to send query string parameters like:

key=value&houses=1&rolling=on&strawberries=17

If your perl script can't handle that then you'll need an intermediate layer like you have. Or modify the script.

Can you GET/POST the form directly to the perl (CGI?) script? Because the query string params will be in @ARGV in perl if you do.

Poor wording above on my part. The real question was can HTML take input from five text boxes, validate them against a regex, and then parse the remaining valid values into a comma-separated list? Since I really didn't think it could I went ahead and implemented all of that in the aforementioned intermediate script, getting called by the HTML form onSubmit - the form will only call the PERL script if the intermediary doesn't return false.

I can GET/POST but I don't need to, having the perl script as the target of my <FORM> is just fine so long as I have valid values in their respective, properly named inputs when I submit the form, which my intermediary takes care of.

Thanks for the query string tips, they'll be useful elsewhere for sure!

Just to be clear, if the form is getting submitted, then it is using either GET or POST depending on what you set <form method=?> to. (Default GET)

Also HTML is not a programming language, just a markup language. If you're executing code with onsubmit, etc. then that is Javascript/JScript.

Yes, exactly. I'm calling a javascript function onSubmit to perform the above mentioned validation and parsing, and that gets POST-ed to the Perl script. I'm also reading in the query string with inlined javascript in my HTML form instead of in the Perl script. I've accomplished everything I wanted to after receiving the basic confirmation of the fact that html has been, is, and will always be strictly markup - virtually any real logic requires another language be used in conjunction.

HTML is most definitely not a programming language, which is why I stayed away for so long. 'Pfft it's easy, and it's not even "real" coding...' In these crazy days of your AJAXs and your iPods and your what-have-yous, I really wish I'd started back when the learning curve was slighter.

Thanks!
