CGI Question

CGI Question

CGI Question

(OP)
This should be simple...

On a form with multiple input buttons, how does the CGI know which button was clicked? I'm using the POST method.

Thanks in advance!

RE: CGI Question

POST or GET does not matter unless you are over filling the GET capacity.
Provided you are not overflowing get (more than 256 I think),.....

Use different values for the 'name' elements in the input tags.
One button has name="blue"......
Second button has name="red".......

With the often used 'sub cgidecode' from the camel books and
%FORM=&cgidecode;

When a button is clicked (submitted),
the corresponding FORM variable is populated.
If button one (named 'one' with value of 'blue') is clicked, then
$var = $FORM{one}; # will set $var to blue.

$FORM{two} will be null.

Thanks,

I'll give it a shot!
