Accessing Category Description in Detailed page

Hi, I want to access the category information in the detailed page template. The variable dump did not show any category information. Any tips on what I should be loading? Been searching around for an hour on terms like access category in detailed etc. Not found anything. :(

Try this...

Create a new global called cat_details...

Code:
sub { 

  my $LinkID = $_[0]; 
  my $CatID; 

  my $table = $DB->table('CatLinks'); 
  my $sth    = $table->select( { LinkID => $LinkID } ) || return $GT::SQL::error; 

  while (my $hit = $sth->fetchrow_hashref) { 
     $CatID = $hit->{CategoryID}; 
  } 

  my $table = $DB->table('Category'); 
  my $sth    = $table->select( { ID => $CatID } ) || return $GT::SQL::error; 

  my @return_loop; 
  while (my $link = $sth->fetchrow_hashref) {  
   push (@return_loop, $link);  
  }  

  return { cat_details_loop => \@return_loop }; 

}

Call it at the top of your HTML template with;

Code:
<%cat_details($ID)%>

... then when you need to show the data, just use something like;

Code:
<%loop cat_details_loop%> 
    <%Title%> <BR> 
    <%ID%>   <BR> 
    <%Description%> <BR> 
    ... etc 
<%endloop%>

Just tried it on my dev installation, and it works a charm Cool

Andy,

Thanks. Will try it out. Do have a question... why do I need the loop? Is that for cases when the link is copied into several categories?

Nah, it just works out faster when trying to grab all the details, and also shorted for the global. Otherwise you would need stuff like;

$

Code:
Description = $hit->{Description}; 
$Title = $hit->{Title}; 
$ID = $hit->{ID}; 
$Image = $hit->{Image};

.. etc.

and then to return them, you would need;

return { cat_Description => $Description, cat_Title => $Title, cat_ID => $ID, cat_Image => $Image };

...etc.

As you can see, my global is a lot shorted, and works better IMO than doing it all the long winded way Tongue

The problem is here (nph-build.cgi, line 553):

Code:
Code:
# Only select Category columns that don't conflict with Links columns.  
my @cat_cols = grep !$links_cols{$_}, keys %{$DB->table('Category')->cols};  
my $sth = $rel->select('Links.*', @cat_cols, 'CategoryID' => $cond);

May someone has an idea how to add:

Select ... "Category.Description as description"?

Then everything should be done.

Solved it:

Code:
my $sth = $rel->select('Links.*', @cat_cols, 'Category.Description AS description, 'CategoryID' => $cond);
