Hi!
I think a better solution would be to use a filtering function, so the source code is not changed and it’s update proof.
I’ve put together a function that might do the trick. Put this to the functions.php file in your active theme directory:
[php]add_filter( ‘rpp_item_after_postprocessing’, ‘rpp_add_category_titles’, 1, 1 );
function rpp_add_category_titles( $post ) {
// Get the post categories
$post_categories = wp_get_post_categories( $post->ID );
$cats = "";
// Concatenate category names to the $cats variable
foreach($post_categories as $c){
$cat = get_category( $c );
$cats .= " ".$cat->name;
}
if ( $cats != "")
$post->author = $cats;
return $post;
}[/php]
Make sure to save the related posts pro options to clear the posts cache.
I haven’t tried this code, but I’m hoping it will work.
