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::SSLGlue::SMTP - make Net::SMTP able to use SSL SYNOPSIS
use Net::SSLGlue::SMTP; my $smtp_ssl = Net::SMTP->new( $host, SSL => 1, SSL_ca_path => ... ); my $smtp_plain = Net::SMTP->new( $host ); $smtp_plain->starttls( SSL_ca_path => ... ); DESCRIPTION
Net::SSLGlue::SMTP extends Net::SMTP so one can either start directly with SSL or switch later to SSL using the STARTTLS command. By default it will take care to verify the certificate according to the rules for SMTP implemented in IO::Socket::SSL. METHODS
new The method "new" of Net::SMTP is now able to start directly with SSL when the argument "<SSL =" 1>> is given. In this case it will not create an IO::Socket::INET object but an IO::Socket::SSL object. One can give the usual "SSL_*" parameter of IO::Socket::SSL to "Net::SMTP::new". starttls If the connection is not yet SSLified it will issue the STARTTLS command and change the object, so that SSL will now be used. The usual "SSL_*" parameter of IO::Socket::SSL will be given. peer_certificate ... Once the SSL connection is established the object is derived from IO::Socket::SSL so that you can use this method to get information about the certificate. See the IO::Socket::SSL documentation. All of these methods can take the "SSL_*" parameter from IO::Socket::SSL to change the behavior of the SSL connection. The following parameters are especially useful: SSL_ca_path, SSL_ca_file Specifies the path or a file where the CAs used for checking the certificates are located. This is typically "etc/ssl/certs" on UNIX systems. SSL_verify_mode If set to 0, verification of the certificate will be disabled. By default it is set to 1 which means that the peer certificate is checked. SSL_verifycn_name Usually the name given as the hostname in the constructor is used to verify the identity of the certificate. If you want to check the certificate against another name you can specify it with this parameter. SEE ALSO
