global $wp_query; echo $wp_query->max_num_pages; This shows the number of pages for the current query. If you want to determine the actual number of posts found by the current query, you may use $wp_query->found_posts Source:- http://codex.wordpress.org/Class_Reference/WP_Query
The simplest way is to add the action right before the query and remove it immediately after. add_action(‘pre_get_posts’, ‘some_function_in_functionsphp’); $my_secondary_loop = new WP_Query(…); remove_action(‘pre_get_posts’, ‘some_function_in_functionsphp’); if( $my_secondary_loop->have_posts() ): while( $my_secondary_loop->have_posts() ): $my_secondary_loop->the_post(); //The secondary loop endwhile; endif; wp_reset_postdata(); EDIT Another technique you can use is to set your own query var and check for that … Read more
By default, WP_Query returns the standard WP_Post objects for the posts being queried. I believe with some clever rewrite and use of the filters given in WP_Query you can add objects to the returned WP_Post objects array. Will this be performant? In my opinion, it will hurt performance more as you will need to join … Read more
Try ‘post__in’ => array(0) Simple and to the point. Update: ‘post__in’ => empty( $include ) ? [ 0 ] : $include,
You would want to use the NOT EXISTS operator along with passing the taxonomy slug, which tells the query not to include any of a chosen category from your custom taxonomy inside the loop. To exclude all posts that are in the taxonomy “fruit” (regardless of fruit kind), here is the snippet: $args = array( … Read more
The tax_query parameter is an array of arrays, not just an array. This: ‘tax_query’ => array( ‘taxonomy’ => ‘video_type’, ‘terms’ => ‘episode’, ‘field’ => ‘slug’, ‘include_children’ => true, ‘operator’ => ‘IN’ ), Should instead be this: ‘tax_query’ => array( array( ‘taxonomy’ => ‘video_type’, ‘terms’ => ‘episode’, ‘field’ => ‘slug’, ‘include_children’ => true, ‘operator’ => ‘IN’ … Read more
Hi @janoChen: Simple answer: no. What follows is what the PHP code for the function wp_reset_query() from /wp-includes/query.php in WordPRess v3.0.4 as well as the functions subsequently called. You can see that it’s primarily about in modifying global variables. When you use new WP_Query($args) you will be assigning the return value from values to a … Read more
Thank you everyone for your help! In the end the query below got me the results I desired – which was to show and sort the posts by a custom field of “publication_date” first – sorting by the date, and if there were multiple of the same date (say, 4 marked June 2013), it would … Read more
The question was for WordPress 3.0, but just in case someone has the same question for a more recent version, from WordPress Codex: “Starting with version 4.1, meta_query clauses can be nested in order to construct complex queries.” https://developer.wordpress.org/reference/classes/wp_query/#custom-field-post-meta-parameters So, that query should work on the current WordPress version.
It’s saved in an option: $default_posts_per_page = get_option( ‘posts_per_page’ ); Reference: get_option Parameters You can see the keys and values of all available options by manually entering the admin url: /wp-admin/options.php Edit Total number of posts: global $wp_query; $total_posts = $wp_query->post_count;
