Making intelligent forms with Perl/ CGI?

[Bes]

Hi

I want to make a form for a website but make it intelligent (i.e. when you click on a radio button, options appear according to what you have pressed, hitting next brings up new options etc)

Any ideas how I do this please? (i.e tutorials)

Thanks

Also are there any drawbacks to using Perl over PHP or something?

Thanks

You can just use simple javascript to bring up options and such. Just change innerHTML etc to add buttons or whatever you need. Ive never used perl so cannot comment on its use, for CGI I always use python. Python functions can also be called directly when the form is submitted.

Use what you know. It makes no sense to use PHP if you know Perl far better. Both are good for web-based applications.

Hmmm trying to kludge CGI, Javascript, and CSS together is proving difficult.... I think I am going to force myself to learn PHP 'on the job' as it seems much easier to make a web app.

javascript is the only way to do this clientside. you need the perl to generate the code tho, and the javascript to show/hide it

If you want the form options to update in real time without appearing to reload the page then some simple Javascript will do the job.

However unhiding data with Javascript is not exactly elegant and if you have a number of options (especially if dynamic) to show then you would be better off using AJAX (Javascript to call AJAX, which populates the data).

Perl & CGI are really used for processing submitted data in the same way ASP, PHP, etc are.
