I have gone to forums, read books. I cannot get a real answer to this.
This should be one of the simplest things to do with perl/cgi....
The selling of visitor form service is big, Perhaps sponsors don't want anyone finding out how to make their own....
I bought a web site. how do I make the HTML <form> submit visitor data that i can retrieve?
If it went into a text file, I could go to my file manager and open it.
Or else, could an <iframe> pick up the stored data? That would be faster, and not require logging in to my website.
