concat string

[clarissa1996]

Hi all

the last line return an error.
The problem is how to concat the variable $session->param("company") with a string ?

Thanks a lot. Clarissa


#!/usr/bin/perl
use CGI::Session;
$session = new CGI::Session("driver:File", undef, {Directory=>'/tmp'});
$session->param("company", 1);
$sql = "../../conf/$session->param("company");

$sql = "../../conf/" . $session->param("company");

You need to use the explicit concatenation operator, '.'

$sql = '../../conf/' . $session->param("Company");

Your problem is that [tt]$session->param("company")[/tt] isn't a variable, it's a method call on an object, and these don't interpolate into strings. If you assign the result of the call to a variable, you can interpolate that:

my $company = $session->param("company");
$sql = "../../conf/$company";

Yours,

That'll be my over-verbose circumlocuity and sendentious pontification slowing me down again. It's my Achilles heel!
