 * I’m having an issue with using pre_get_posts I’m currently using a pre_get_posts
   function to control the loop output of my category template which works fine 
   but I also have a search template and I’m trying to incorporate the arguments
   used in there into a separate pre_get_posts function.
 * This is what I am using, when used it kills the site, white screen, as you might
   have noticed I’m no expert…
 * If anyone is able to point out my most likely glaring mistake I’ll be very grateful.
 * function paginate_search ( $query ) {
    if( $query->!is_admin() ) { foreach($_POST[‘
   filter_cat’] as $fcat){$fcat_list .= $fcat . “,”;} query_posts( array_merge (
   array ( ‘cat’ => $fcat_list, ‘posts_per_page’ => 6, ‘paged’ => $paged ), $wp_query-
   >query ) ); } } add_action( ‘pre_get_posts’, ‘paginate_search’ );
