You should read the function reference for WP_Query on the WordPress codex. There you have a lot of examples to look at. If you don’t want to loop over the result set using a while, you could get all posts returned by the query with the WP_Query in the property posts. For example $query = … Read more
You have to change child_of to post_parent and also add post_type => ‘page’: WordPress codex Wp_query Post & Page Parameters <?php $args = array( ‘post_type’ => ‘page’, ‘posts_per_page’ => -1, ‘post_parent’ => $post->ID, ‘order’ => ‘ASC’, ‘orderby’ => ‘menu_order’ ); $parent = new WP_Query( $args ); if ( $parent->have_posts() ) : ?> <?php while ( … Read more
I would solve this with a filter on WP_Query. One that detects an extra query variable and uses that as the prefix of the title. add_filter( ‘posts_where’, ‘wpse18703_posts_where’, 10, 2 ); function wpse18703_posts_where( $where, &$wp_query ) { global $wpdb; if ( $wpse18703_title = $wp_query->get( ‘wpse18703_title’ ) ) { $where .= ‘ AND ‘ . $wpdb->posts … Read more
The first several work as you would expect: = equals != does not equal > greater than >= greater than or equal to < less than <= less than or equal to LIKE and NOT LIKE LIKE and NOT LIKE are SQL operators that let you add in wild-card symbols, so you could have a … Read more
any should retrieve any type: $args = array( ‘p’ => 42, // ID of a page, post, or custom type ‘post_type’ => ‘any’ ); $my_posts = new WP_Query($args); Note the description of any in the documentation: ‘any’ – retrieves any type except revisions and types with ‘exclude_from_search’ set to true. For more information, have a … Read more
You can use the post_status parameter: * ‘publish’ – a published post or page * ‘pending’ – post is pending review * ‘draft’ – a post in draft status * ‘auto-draft’ – a newly created post, with no content * ‘future’ – a post to publish in the future * ‘private’ – not visible to … Read more
No, it is not possible to order by taxonomy, because from a certain type of standpoint, that doesn’t actually make much sense. Taxonomies are ways to group things together. So the point of having a taxonomy on posts would really be to have terms in that taxonomy that are shared between posts. If a taxonomy … Read more
I did some more testing with this, and honestly can’t find a reason it wouldn’t work (unless the code above is just a snippet and the real code fits on my examples below). I did, however, discover a couple of things that might lead you in the right direction. 1) By itself, this meta query … Read more
orderby should be meta_value_num, or meta_value, not the name of the key. See WP_Query orderby parameters.
You are right to say: Never use query_posts anymore pre_get_posts pre_get_posts is a filter, for altering any query. It is most often used to alter only the ‘main query’: add_action(‘pre_get_posts’,’wpse50761_alter_query’); function wpse50761_alter_query($query){ if( $query->is_main_query() ){ //Do something to main query } } (I would also check that is_admin() returns false – though this may be … Read more
