form

Attributes

method ("get" or "post")
action (URL of CGI program)
enctype

Each element within a form has a name associated with it. When the information is sent back to the server, the CGI program will access the information by name. Thus, the front-end form and the back-end program must use the same names.

While exploring forms, it is useful to use a simple "echo" CGI program, which will simply echo back the name/value information your form submitted (http://cscie12.dce.harvard.edu/echo).
