Shorten the Title

Heya ll,

Been trying to hack together a little global that will do nothing but take the title from a link and shorten it to however long I want it to be. Not working that well - but then I also know next to nothing about writing globals - can anyone help? Smile

Code:
sub { 
my $link = $_[0]; 
if (length $link->{Title} > 20) {  
$link->{Title} = substr($link->{Title}, 0, 20) . '...';  
} 
return $Title; 
}

Safe swoops

Here's the short_description global you may be able to modify to suit the title.

sub {
my $tags = shift;
my $desc = $tags->{Description} or return "No description on this template";
length $desc <100 and return $desc;
my $short = substr ($desc, 0, 100);
$short =~ s/\s\S+?$//;
$short .= " ...";
return $short;
}

Regards

Even easier would be to pass the variable in...

Code:
sub {  
   my $length_l = 100; 
   my $value = $_[0] or return "No value...";  
   length $value < $length_l and return $value;   

   my $short = substr ($value, 0, $length_l);  
   $short =~ s/\s\S+?$//;  
   $short .= " ...";  
   return $short;  
}

..and call with;

<%global_name($FieldName)%>

Cheers
