Homework and Emergencies Emergency UNIX and Linux Support Perl error: Can't call method "value" on an undefined value Post 302675105 by otheus on Saturday 21st of July 2012 05:00:58 PM

Code:
            my $fcell = $worksheet->get_cell($row, 11);
            my $name = $fcell->value();

What's probably happened is that get_cell() returned an undefined object (perhaps because that cell was undefined or empty), and thus, $fcell->value() doesn't have any meaning. Test $fcell before trying to use it:
Code:
            next unless $fcell;

As to your 2nd question:

also to add. I have removed my personal info in the email section but that does not seem to work as well when i input the data. we have some older scripts where we do not specify the smtp host and the ip we only specify the email address. is this at all possible in this script to?
That depends on your email set up. On most UNIX systems you can send the mail via sendmail directly, but it's not portable to, say, windows systems:
Code:
open(SMTP,"|/usr/lib/sendmail -t");
print SMTP "From: $sender\n";
print SMTP "To: $recipient\n";
print SMTP "Subject: $subject\n";
print SMTP "\n";
print SMTP join("\n",@log);
print SMTP "\n";
close SMTP;

NAME
Net::SMTP::Server::Client - Client session handling for Net::SMTP::Server. SYNOPSIS
use Carp; use Net::SMTP::Server; use Net::SMTP::Server::Client; use Net::SMTP::Server::Relay; $server = new Net::SMTP::Server('localhost', 25) || croak("Unable to handle client connection: $! "); while($conn = $server->accept()) { # We can perform all sorts of checks here for spammers, ACLs, # and other useful stuff to check on a connection. # Handle the client's connection and spawn off a new parser. # This can/should be a fork() or a new thread, # but for simplicity... my $client = new Net::SMTP::Server::Client($conn) || croak("Unable to handle client connection: $! "); # Process the client. This command will block until # the connecting client completes the SMTP transaction. $client->process || next; # In this simple server, we're just relaying everything # to a server. If a real server were implemented, you # could save email to a file, or perform various other # actions on it here. my $relay = new Net::SMTP::Server::Relay($client->{FROM}, $client->{TO}, $client->{MSG}); } DESCRIPTION
The Net::SMTP::Server::Client module implements all the session handling required for a Net::SMTP::Server::Client connection. The above example demonstrates how to use Net::SMTP::Server::Client with Net::SMTP::Server to handle SMTP connections. $client = new Net::SMTP::Server::Client($conn) Net::SMTP::Server::Client accepts one argument that must be a handle to a connection that will be used for communication. Once you have a new client session, simply call: $client->process This processes an SMTP transaction. THIS MAY APPEAR TO HANG -- ESPECIALLY IF THERE IS A LARGE AMOUNT OF DATA BEING SENT. Once this method returns, the server will have processed an entire SMTP transaction, and is ready to continue. Once $client->process returns, various fields have been filled in. Those are: $client->{TO} -- This is an array containing the intended recipients for this message. There may be multiple recipients for any given message. $client->{FROM} -- This is the sender of the given message. $client->{MSG} -- The actual message data. :) AUTHOR AND COPYRIGHT Net::SMTP::Server / SMTP::Server is Copyright(C) 1999, MacGyver (aka Habeeb J.
