If the query is only for a small number of posts, then as linked to by Alex you can sort in php. However, this does not scale well. As suggested by Kovshenin – a better alternative is to use posts_orderby filter: $post_ids = array(83,24,106,2283,14); $args = array( ‘post_type’ => ‘post’, ‘post__in’ => $post_ids, ‘numberposts’ => … Read more
Instead of trying to display all the matching events on your by-date page, you could try to display through ?post_type=event like this: function rewrite_rule_by_date() { add_rewrite_rule(‘by\-date/([0-9]{4}\-[0-9]{2}\-[0-9]{2})$’, ‘index.php?post_type=event&event_date=$matches[1]’, ‘top’); } add_action( ‘init’, ‘rewrite_rule_by_date’ ); function query_var_by_date() { add_rewrite_tag( ‘%event_date%’, ‘([0-9]{4}-[0-9]{2}-[0-9]{2})’); } add_action( ‘init’, ‘query_var_by_date’ ); function custom_event_query( $query ) { if ( get_query_var( ‘event_date’ ) && … Read more
To get a list of all terms of taxonomy X whose posts are associated to terms from taxonomy Y too, we have to: Get all term IDs for both taxonomies Create a tax query to fetch all posts, because we don’t want to show empty term archives. Format the result in a hierarchical list. Let’s … Read more
Change it up a bit and use have_posts method to check if there are any results: <?php $args = array( ‘post_type’ => ‘questions’, ‘posts_per_page’ => ‘3’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘types’, ‘field’ => ‘slug’, ‘terms’ => ‘customer-service’ ) ) ); $loop = new WP_Query( $args ); if ($loop->have_posts()){ ?> <h4>Frequently Asked Questions</h4> <ul … Read more
A rought method would be to set value of balance to ‘mt1.meta_value’ and then use a ‘posts_request’ filter to remove the escaping quotes: $args = array( ‘post_type’ => ‘post’, // maybe not ‘meta_query’ => array( array( ‘key’ => ‘balance’, ‘compare’ => ‘>=’, ‘value’ => ‘mt1.meta_value’, // this will be treated as a string ‘type’ => … Read more

But there is a way to order by multiple custom fields using posts_orderby filter hook, so first create a function that will add your orderby … Read more

WP_Object_Cache is WordPress’ class for caching data which may be computationally expensive to regenerate, such as the result of complex … Read more
the_post places the next post object from $query->posts in the global $post and calls setup_postdata, which assumes $post is a post object, as it tries to access member vars of that object, which is where the errors come from. In this case $posts is just an array of IDs instead of post objects. If you … Read more
Getting meta data from a WP_Post object is already possible. Just write: echo $post->your_meta_key; This will call get_post_meta( $this->ID, $your_meta_key, true ) behind the scenes. See the documentation and the source code for WP_Post. This works also with instances of WP_User, but not with WP_Comment as far as I know. Don’t forget to escape the … Read more
