Besides your problem (which, as
Abigail-II notes, is not apparent from the piece of code you posted), that is a horrible construct - flag variables like
$errorcount are a red flag, as are collections of
$foo_bar,
$foo_baz,
$foo_quux variables. An initial cleanup leads to:
sub print_error {
my $message = shift;
print "<br><font color='red'>$message</font>";
# etc..
}
unless($title and $url and $description and $keywords) {
$title
or print_error "Please enter a title.";
$url
or print_error "Please enter a valid address.";
$description
or print_error "Please enter a description.";
$keywords
or print_error "Please enter some keywords.";
# ...
}
You could still do a lot better if $title, $url etc where all stored in a hash. See Mark-Jason Dominus' excellent Program Repair Shop and Red Flags article series on Perl.com.
Update: thanks to The Mad Hatter for catching a small mishap. (s/$shift/\$message/)
