Okay Paul, Ivan and Andy.

Sorry for making everybody go in limbo.

I did have a global that was returning the links in the same category on a detailed page. Now with Ivan's global, I get the total count of links in a category.

But When I try to use Ivan's global like this:

<%if linkstotal($ID) > 1%><%category_links%><%endif%> I get nothing.

When I try <%linkstotal($ID)%> by itself, I do get the right count, but when compared to another number, I don't get anything...

Thank you for your time.

It is a parser limitation I'm afraid, you can't use global tags inside if tags. I tried to think of a way round it but my boiled eggs need continual attention :)

If I think of anything and no-one has replied I'll let you know.

What about;

<%if linkstotal($ID) > 1%><%linkstotal($ID)%><%endif%>

Just guessing here Wink

Ok..so maybe it is a limit in the template parser, as Paul stated. If so, I'm not sure if there is a way around it, without editing the parser itelf (something I would most definatly not want to do...lol) Frown

Try this

Code:
sub { 
  my $link_id = shift; 
  my ($cat_id, $cat_name) = each %{$DB->table('Links')->get_categories ($link_id)}; 
  return { links_total => $DB->table('CatLinks')->count( { CategoryID => $cat_id }) }; 
}

and use it as

<%category_links($ID)%>
<%if links_total > 1%>
........
<%endif%>

Mmm...what about;

Code:
sub {    

  my $link_id = shift; 
  my ($cat_id, $cat_name) = each %{$DB->table('Links')->get_categories ($link_id)}; 
  my $send_back = $DB->table('CatLinks')->count( { CategoryID => $cat_id }); } 

  if (!$send_back) {  

      $send_back = "Nothing"; 

  } 

return $send_back;

That will return a number if anything is returned, if not, then it will print "Nothing" Wink

Re: [nt6] <%if category_links > 1%> In reply to

I can't figure this out...it seems globals/ifs do work together...

Code:
sub { return 1 } 

<%if a%> 
<%a%> 
<%else%> 
Nope 
<%endif%>

Before I created the "a" global it showed nope, but after it printed 1

<%if category_links > 1%>
