You can have more than two. You could have as many as you like but you may have performance penalties if you try to use too many. I’d expect this to be true especially if you use an OR relationship. See the following for a way to create your tax_query array dynamically. https://wordpress.stackexchange.com/a/97444/21376 To adapt … Read more
wp_get_object_terms( $post_id, $taxonomy ) will return an array of the term objects for that post of that taxonomy. $post_id can also be an array of ids (this will return all terms attached to any post in the array), and $taxonomy can also be an array of taxonomies.
Yes, You can call action “pre_get_posts”. add_action(‘pre_get_posts’,’search_filter’); You can add parameter : $args = array( ‘post_status’ => ‘publish’, ‘posts_per_page’ => 6, ‘paged’ => $paged, ‘meta_key’ => ‘event_date’, ‘orderby’ => ‘meta_value_num’, ‘order’ => ‘ASC’ ); You can use above parameter e.g. : function search_filter($query){ if ( !is_admin() && $query->is_main_query() ) { $query->set(‘post_status’, ‘publish’); $query->set(‘meta_key’, ‘event_date’); $query->set(‘orderby’, … Read more
I have found an answer by myself, for those landing here by google: $taxq = array( array( ‘taxonomy’ => ‘story_lng’, ‘field’ => ‘id’, ‘operator’ => ‘NOT EXISTS’, ) ); That results in AND (NOT EXISTS( SELECT 1 FROM wp_term_relationships INNER JOIN wp_term_taxonomy ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id WHERE wp_term_taxonomy.taxonomy = ‘story_lng’ AND wp_term_relationships.object_id = wp_posts.ID)) AND … Read more
There is no such hierarchy in WordPress, accessing a custom taxonomy directly simply 404. This works for all taxonomies, build-in or not. There is unfortuantely no other work around to this but to create a page You should create a custom page template with a custom query to list your taxonomy terms, something like the … Read more
number_posts is not a valid parameter in pre_get_posts, you should be using posts_per_page You should also include a check (!is_admin()) in your query to check whether you are on the front end or back end as pre_get_posts alters back end queries as well Rewrite your code to the following: add_action( ‘pre_get_posts’, function ( $query ) … Read more
If I try to add &posts_per_page=15 to url, it doesn’t work: it won’t change number of post. I wonder if you’re looking for a custom query variable, e.g. ppp, to change the number of posts for the main query: add_filter( ‘query_vars’, function( $vars ) { $vars[] = “ppp”; return $vars; } ); add_action( ‘pre_get_posts’, function( … Read more
Change predefined posts_per_page to minimum value in wordpress settings or add code below to functions.php. WordPress using default parameter. For example: 10. And if your settings in query_posts or WP_Query look like “posts_per_page=>2” and number of posts in custom post type less then 10, after clicking to /page/2/ you will redirected to page 404. Use … Read more
I think that the best solution is to hook into the pre_get_posts action hook. First, it is checked if we are in an archive of your custom taxonomy, then set include_children to false for the tax_query argument of the query. add_action( ‘pre_get_posts’, ‘cyb_pre_get_posts’ ); function cyb_pre_get_posts( $query ) { //Assuming the slug of the custom … Read more
(Revised on March 25 2020 UTC) So in this revised answer, I’ll just begin with the code: Define the variables: (I intentionally included only the $args part) // define POSTed/submitted variables here like $paged, $display_count and $direction // define the offset/’direction’ stuff here // then define your $args array $args = array( ‘post_type’ => ‘product’, … Read more
