Hi,

Do you mean you want a global, which would for example:

1) Top Cat
2) Top Cat/Test
3) Top Cat/Test 2
4) Top Cat/Test 2/Sub Cat
5) Top Cat/Test 2/Sub Cat/Another Cat
6) Top Cat/Test 3

...and you wanna get the category "2", and all its sub-categories?

Cheers

Hi,

Try this global:

get_cats_from_this_cat

Code:
sub { 

 my $cat = $_[0]; 
 my $all_ids = $DB->table('Category')->children($cat); 
 push @$all_ids, $cat;  

 my $db_obj = $DB->table('Category'); 
    $db_obj->select_options ('ORDER BY Full_Name DESC'); 

 my $cond = GT::SQL::Condition->new('CategoryID', 'IN', $all_ids); 
 my $sth = $db_obj->select ( $cond) || die $GT::SQL::error; 

 my @cats; 
 while (my $hit = $sth->fetchrow_hashref) { 

   $hit->{URL} = $CFG->{build_root_url} . '/' . $DB->table('Category')->as_url( $hit->{Full_Name} ) . '/' . $CFG->{build_index}; 
   push @cats, $hit; 
 } 

  return { cat_loop => \@cats } 

}

..then in category.html, put:

Code:
<%get_cats_from_this_cat($category_id)%> 
<%if cat_loop.length%> 
   <%loop cat_loop%> 
     <%include subcategory.html%> 
  <%endloop%> 
<%endif%>

Untested, but I think this will do what you want Smile

Mmm,, really? :/ Can't see any reason you would get that error (normally its due to a space at the beginning of the sub { bit or an extra space in sub { - can you send over GLinks admin details, and I'll take a look otherwise.
