Sorcery of Form Input
Look around the WWW Lab
This document is used my me to experiment with various aspects of
CGI Forms, CGI scripts, WWW client program abilities, and testing
of the NCSA Http Daemon we use for this web server.
You can experiment but I make no guarantees on validity of any results.
Warning: This page will not work on client programs without
support for forms.
CGI Executable Links
This is a plain an ordinary Query Link
to a CGI program!
CGI Link can also have ``Path Information'' and
``GET query values''.
Using a POST Form.
Using a POST Form, but with extra ``Path Information'' and
``GET Query String''.
A Form can use the GET method too, with ``Path Information''. However
any extra ``GET Query String'' in the CGI URL is useless.
Multiple Submit Buttons IF submit form input has a name, then the
specific button selected by the user is returned!
HTML 4.0 Buttons
As of HTML 4.0 the BUTTON form element was added. This was suposed to replace
the INPUT buttons above.
NOTE: older web client (like netscape ) do not understand this type.
Image Form Input
An image form type acts like a sumbit button, but also returns the point of
`click' by the user.
WARNING: the `value' is ignored as it returns the `x' and `y' position of the
users click instead.
