Open existing HTML page from perl script

Hi,

I am putting together a simple website and would like visitors to be
able to type a number into a form (say 1234) and a perl script should
run open an existing page called .../1234.html or generate an error
page if the use enters a wrong number. I will have already uploaded
the page before a user enters the number so the per script can open it
rather than generate a new one (unless it can be generated on the fly
which may be better?)

I think this should be able to be done but I have no idea how. for
instance how do i append the '.html' to the file name.

The website is here (www.ashcraftframing.co.uk) . The fom is in the
bottom right of the page and launches a invopice page for PayPal. I
want users to enter a invoice number corresponding to a page I have
already up loaded.

If anyone know of some pre existing code I can modify I'd be very
grateful. I have only done a little 'cook book' scripting so please
go easy on me!

Thanks

That's easy by returnning a redirection.
For example,

use CGI;

my $q =3D CGI->new;
my $page =3D $q->param("page_number");
print $q->redirect("/$page.html");

An onClick attribute to your button will do the trick. Just something
like this



will do what you describe, but you will need to write more to validate
the input before trying to display the invoice.

It is probably also possible to generate the invoice on the fly. How
difficult that might be depends on the format you want to see.

HTH,

Rob
