I’m going to answer this myself, but it was the very clever @simonwheatley of Code for the People that solved this one for me. Instead of using wp_reset_postdata() or wp_reset_query(), you can use the following: $publication->reset_postdata(); Where $publication is your query object. The working code now looks like: $publication = new WP_Query( array( ‘connected_type’ => … Read more
Please try this: $args = array( ‘category_name’ => ‘cat1’, ‘posts_per_page’ => 5, ‘orderby’ => ‘rand’, ); $pc = new WP_Query( $args ); where ‘rand’ should give you a random order of your posts. For more info check out the Codex on WP_Query order parameters here.
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 ] : $include,
Hi @janoChen: Simple answer: no. What follows is what the PHP code for the function wp_reset_query() from /wp-includes/query.php in WordPRess v3.0.4 as well as the functions subsequently called. You can see that it’s primarily about in modifying global variables. When you use new WP_Query($args) you will be assigning the return value from values to a … Read more
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;
pre_get_posts will run the same query, so both will take same time. But, If you utilize pre_get_posts action you will save one or more SQL queries. Right now, WordPress is running default query and then you run your query with this function which replace the results of the default query (resulting, default query is of … Read more
