pre_get_posts hook should work for this: add_action( ‘pre_get_posts’, ‘wpse35832_pre_get_posts’ ); function wpse35832_pre_get_posts( $wp ){ if( $wp->query_vars[‘p’] == 200 ): $wp->query_vars[‘p’] = 100; endif; return $wp; } It may work a bit differently if pretty permalinks are used, different query vars may be set, not sure though.
$args = array( ‘post_status’ => ‘publish’, ‘post_parent’ => $post_id ); $children = get_posts( $args ); if( count( $children ) > 0 ) { //has children } else { //does not have children } Docs: get_posts() This should also allow you to have access to the data of the children, should you need it. If you … Read more
You can use the following code, which first gets the most recent comments, then using the post_ids associated with those comments, queries the database for those posts: // Get the 5 most recent comments $recent_comments = get_comments( array( ‘orderby’ => ‘comment_date’, ‘number’ => 5 ) ); // If there are any posts with comments if … Read more
I had this same problem until I realized you don’t actually have to query by the event start date, only the end date. As long as the event’s end date has not past it doesn’t matter whether the start date is in the future or not. All you have to do is grab all the … Read more
Look in wp-includes/general-template.php at the function wp_login_form(). Follow the functions called there. I’d say: just use wp_login_form(). It does probably everything you need, and you can customize it.
It’s easy. 🙂 You would use get_posts function. See WP_Query class for complete list of parameters that you can use. function get_posts_by_view_count() { $ids = array(); $args = array( ‘orderby’ => ‘meta_value_num’, ‘order’ => ‘DESC’, ‘meta_key’ => ‘post_view_count’ ); $posts = get_posts( $args ); if( $posts ) { foreach( $posts as $post ) { $ids[] … Read more
“This code works” – but it doesn’t! If you’re gonna cache paginated posts, you’ll need to store them chunked: if ( ! $my_paged = absint( get_query_var( ‘paged’ ) ) ) $my_paged = 1; if ( ! $my_query = get_transient( “recent_$paged” ) ) { $my_query = new WP_Query( “cat=3&posts_per_page=5&paged=$my_paged” ); set_transient( “recent_$paged”, $my_query, 60 * 60 … Read more
Your table names are wrong. note in your first query the use of $wpdb->posts to reference the posts table. however– this is a very simple query that can be done via the API rather than writing SQL queries from scratch. Use a new WP_Query instance instead.
wp_list_pages will only output hierarchical post types. If we look at the function in source, we’ll see that it calls get_pages to load pages for output. If we look at get_pages function in source, we’ll see: // Make sure the post type is hierarchical $hierarchical_post_types = get_post_types( array( ‘hierarchical’ => true ) ); if ( … Read more
Following code generates the array to use as argument. <?php // Excluded CPTs. You can expand the list. $exclude_cpts = array( ‘portfolio’ ); // Builtin types needed. $builtin = array( ‘post’, ‘page’, ‘attachment’ ); // All CPTs. $cpts = get_post_types( array( ‘public’ => true, ‘_builtin’ => false ) ); // remove Excluded CPTs from All … Read more
