I want to merge two queries together and remove duplicate. I got it working individually. Now I got it working together but the results are not mixed and the duplicates are not removed. So I got the first queries result and then the second query result...
$fav_author_list = get_user_option( 'favorite-authors', fav_authors_get_user_id() );
$fav_categorie_list = get_user_option( 'favorite-categories', fav_categories_get_user_id() );
$rm_blog_args = array(
'posts_per_page' => -1,
'author__in'=> $fav_author_list,
'post_type' => 'post'
);
$rm_blog = new WP_Query($rm_blog_args);
$fb_args = array(
'posts_per_page' => -1,
'category__in'=> $fav_categorie_list,
'post_type' => 'post'
);
$fb = new WP_Query($fb_args);
// Final Query
$final_query = new WP_Query();
// Merging queries
$final_query->posts = array_merge( $rm_blog->posts, $fb->posts);
// Recount
echo $final_query->post_count = count( $final_query->posts );
// Remove duplicate post IDs
$post_ids = array();
foreach( $final_query->posts as $item ) {
$post_ids[] = $item->ID;
}
$unique_posts = array_unique($post_ids);
if($final_query->have_posts()) : while ( $final_query->have_posts() ) : $final_query->the_post();
