To clear up some confusion in previous answers, pre_get_posts isn’t a filter so you don’t need to return anything. Your only problem that I see is the if: if ( !is_search() && !in_array( get_post_type(), $post_types ) ) return; Basically get_post_type() is going to return false during pre_get_posts because the global $post hasn’t been set yet … Read more
There’s not really a way to “stop” the main query. There are plenty of filters to modify it, just nothing to turn it off completely. The best you may be able to do is hook into posts_request, which fires right before the data is hit, and return an empty string or something non-sensical. This is … Read more
The init hook runs well before pre_get_posts so dumping the query at that point– on init— isn’t going to reflect anything that will be done much later. I don’t think there is anything wrong with your code, you misunderstand the sequence of actions. What you expect to happen isn’t what actually happens.
As I have stated in comments, this will take some work. In short, you will need the following: Get all the terms from the style taxonomy. Here we would only want the term ids Get the current tax_query from the colour taxonomy. Use each term from the style taxonomy and create a new tax_query to … Read more
It appears that you want to create a custom page template to display a custom post type? If so, you don’t really need to mess with pre_get_posts at all. First, create your custom page template. I assume you’ve already done this. Second, you need to create a custom query, using WP_Query(): global $post; $types = … Read more
You don’t need to! With a little understanding of how URLs and query vars work, we can do this entirely within the URL of the page, with no additional PHP code First we have a URL: example.com/abc/123 Then we have a rewrite rule. The rule has a regex pattern that matches the URL, and a … Read more
You can set tax query in pre_get_posts hook as well: $query->set(‘tax_query’, array(__standart parameters__));
From a plugin or your theme’s functions.php file: function wpse106861_mod_query( $query ) { /* are we on the blog page ? */ if ( $query->is_home() && $query->is_main_query() ) { /* get ID of news category */ $news_id = get_cat_ID( ‘news’ ); /* exclude posts in new from query */ $query->set( ‘category__not_in’ => array( $news_id ) … Read more
Because comment_status is not a built-in query argument – but you can easily implement it: function wpse_214323_query_by_comment_status( $where, $wp_query ) { global $wpdb; if ( ! empty( $wp_query->query_vars[‘comment_status’] ) ) { $status = $wp_query->query_vars[‘comment_status’]; if ( $status !== ‘open’ ) $status=”closed”; $where .= ” AND $wpdb->posts.comment_status=”$status””; } return $where; } add_filter( ‘posts_where’, ‘wpse_214323_query_by_comment_status’, 10, 2 … Read more
