CGI beginner - why no refresh?
Posted on 2002-07-03
I think I may under a misapprehension as to what CGI is all about.
I have debugged and debugged my perl software down to a point wherby it is a simple item that is going wrong. (The bones of the code are below)
Why does this code not give me "Fred" in my text area? I know that the correct path is being followed when I press the button as the printing of the string "$MyString" at the end of the code gives me the correct printout - it just doesn't refresh my text area.
I was under the apprehension that if I send a whole new web page, this would replace what was on the screen but it doesn't seem to.
What am I missing when it comes to CGI?
How do I refresh what is on my screen?
Many thanks from a CGI beginner.
$co = new CGI;
if ( ! $co->param())
$MyString = "Hello";
if ($co->param('MyButton') ne "")
