Full Discussion: Perl error: Can't call method "value" on an undefined value
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;

calibre-smtp

CALIBRE-SMTP(1) 						      calibre							   CALIBRE-SMTP(1)

NAME

       calibre-smtp - part of calibre

SYNOPSIS

       calibre-smtp  [options] [from to text]

DESCRIPTION

       Send  mail using the SMTP protocol. calibre-smtp has two modes of operation. In the compose mode you specify from to and text and these are
       used to build and send an email message. In the filter mode, calibre-smtp reads a complete email message from STDIN and sends it.

       text is the body of the email message.  If text is not specified, a complete email message is read from STDIN.  from is the  email  address
       of the sender and to is the email address of the recipient. When a complete email is read from STDIN, from and to are only used in the SMTP
       negotiation, the message headers are not modified.

       Whenever you pass arguments to calibre-smtp that have spaces in them, enclose the arguments in quotation marks.

       --version
	      show program's version number and exit

       -h, --help

       -s, --subject
