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;
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
Sessions aren’t enabled in wordpress by default, if you want to activate php sessions add this at the beginning of your functions.php: if (!session_id()) { session_start(); } You now can use $_SESSION[‘your-var’] = ‘your-value’; to set a session variable. Take a look at the PHP documentation on sessions. Update: There was a second answer, which, … Read more
Important disclaimer: the proper way to do this is NOT to modify your table structure, but to use wp_usermeta. Then you will not need to create any custom SQL to query your posts (though you’ll still need some custom SQL to get a list of everyone that reports to a particular supervisor – in the … Read more
The $wpdb object has some properties getting set for that: global $wpdb; // Print last SQL query string echo $wpdb->last_query; // Print last SQL query result echo $wpdb->last_result; // Print last SQL query Error echo $wpdb->last_error; Note: First of all you have to set define( ‘SAVEQUERIES’, true ); in your wp-config.php file at root folder … Read more
I suppose this was heavy, but to answer your original question, I’ve collected all of the posts id’s in an array in the first loop, and excluded those posts from the second loop using ‘post__not_in’ which expects an array of post id’s <?php $args1 = array(‘category_name’ => ‘test-cat-1’, ‘order’ => ‘ASC’); $q1 = new WP_query($args); … Read more
I think that now I understand what you are trying to do. When you run a custom query with WP_Query and set the limit to get only 5 posts per page, only 5 posts will be retrieved by the query and that query will only hold 5 posts, BUT for the sake of pagination, WP_Query … Read more
