I’ll take another shot. The following should modify the main query, such that it will include in its loop any posts that belong to no term of the Edition custom taxonomy. add_filter(‘pre_get_posts’,’better_editions_archive’); function better_editions_archive( $query ) { if ( $query->is_tax( ‘edition’ ) && $query->is_main_query() ) { $terms = get_terms( ‘edition’, array( ‘fields’ => ‘ids’ ) … Read more
To achieve adding a custom sortable column to the WP_List_Table of your post type within the WordPress administration back-end dashboard, you will need to do the following: Replace all occurrences of YOUR-POST-TYPE-NAME with your actual post type name. Replace all occurrences of YOUR-TAXONOMY-NAME with your actual taxonomy name. Replace all occurrences of YOUR COLUMN NAME … Read more
As I couldn’t find any filter to override the WP_Posts_List_Table class, I propose a quite hacky solution by doing this: Query only parents in pre_get_posts; Query their children on wp and change $wp_query->posts accordingly. This might need some more work as I’m probably breaking pagination numbers or so. // Use a query variable to control … Read more
I think pre_get_posts should work with $query->set(). Only problem I see there is you are using get_the_ID() in a hook. Try using global $post variable to get the current post id.
It does’t work because you can’t use set to change all query vars. Simplest way to do the trick is set ‘s’ to an empty string: add_action( ‘pre_get_posts’, function( $query ) { if ( ! is_admin() && $query->is_main_query() && $query->is_search() ) { $taxquery = array( … ); $query->set( ‘tax_query’, $taxquery ); $query->set(‘s’, ” ); } … Read more
When ‘pre_get_posts’ is fired, there are a lot of things that WordPress has already done like setup all the query variables (also the query you don’t send) and setup all the conditional properties (all the is_* properties). So, if you want completely replace the query you should reset all that things and set your own. … Read more
Improve your conditional to include a check for post type being queried. It can be done via WP_Query::get method So, where you have if ( !is_admin() ){ $query->set( ‘meta_key’, ‘_ct_selectbox_52f65ae267764’ ); $query->set( ‘meta_value’, $city ); return; } replace with if ( ! is_admin() && in_array ( $query->get(‘post_type’), array(‘event’,’venue’) ) ) { $query->set( ‘meta_key’, ‘_ct_selectbox_52f65ae267764’ ); … Read more
Your filter has a bug in it, namely when you call is_main_query, you’re not checking if the passed query is the main query, your checking if the currently active query is the main query, which will always be true. So instead try this: add_action( ‘pre_get_posts’, ‘some_name’); function some_name($query) { if ($query->is_front_page() && $query->is_main_query()) { $query->set( … Read more
As Milo said : $query->set(‘meta_key’, ‘wpcf-object-sold-status’ ); $query->set(‘orderby’, array(‘meta_value’ => ‘ASC’, ‘date’ => ‘DESC’)); // $query->set(‘order’, ‘ASC DESC’ ); // not needed Relevant link: https://make.wordpress.org/core/2014/08/29/a-more-powerful-order-by-in-wordpress-4-0/
This works for me in order to list the items uploaded by a user on the media library. function users_my_media_only( $wp_query ) { if ( false !== strpos( $_SERVER[ ‘REQUEST_URI’ ], ‘/wp-admin/upload.php’ ) ) { $current_user = wp_get_current_user(); $current_user = $current_user->ID; if ( ! current_user_can( ‘manage_options’ ) ) { global $current_user; $wp_query->set( ‘author’, $current_user->id ); … Read more
