I'm wondering if someone can do me an enormous favour and write a cgi
for me please, I just can't get my head around the books I have, they
might just as well be written in Klingon.
I would like to be able to enter a number into a form. (eg 1234)
This number would also be output to result.html which I will get to in
a minute.
To read a value from a CGI form you need to use the module CGI, you can
add it to your program like this:
use CGI qw(:standard);
With this in place you can read the values, for example if the entry box
on the form is called "number" you read it using this:
$number = param ('number);
Now you have that in place, you can set your page up to display the
number entry box
if there is no number or the results if there is one:
#!/usr/bin/perl
use CGI qw(:standard);
$number = param ('number);
if ($number ne undef) {
#code for calculating the result
}
else {
#code for the html form.
}
Hope this helps you to get started.
