Passing form input to subroutine

[Charlie Farinella <cf...@appropriatesolutions.com>]

I'm passing parameters from a form to a result page, and then trying to
call a subroutine from an external package to process the variable.

I'm using $Request->Form to get the value from the form to the result
page, but my subroutine is unable to make use of it.  What is required
to make the subroutine aware of the variable?

In my applications, I generally scoop up the form into a hash and then pass it 
as a hash ref. eg:

my $form = $Request->Form();
myfunc($form);

sub myfunc {
	my $form = shift;
	print "Use like this: ", $form->{key};
	print "Or like this: ", $$form{key};
	}

Hope this helps

You can do $main::Request->Form from any perl package,
or if you have GlobalPackage set to something like MyPackage,
you can do $MyPackage::Request->Form.  This inherently makes
your package aware of ASP type variables, which might be bad design.
You might better do something like &My::sub($Request->Form) when
you call it from the ASP script in the first place.  Request->Form
is just a hash ref so is pretty ASP independent, and the params
could come from anywhere.

Regards,

Josh
