As explained here Post List components queries can be customized using the wpak_posts_list_query_args filter hook.
Here’s how to customize a Post List component (slug my-component-slug) query so that the posts can be sorted by alphabetical order instead of default chronological order:
//To put in the "php" folder of your WP-AppKit theme: function my_custom_query( $query_args, $component ) { if( $component->slug === 'my-component-slug' ) { $query_args['orderby'] = 'name'; $query_args['order'] = 'ASC'; //see https://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters } return $query_args; } add_filter( 'wpak_posts_list_query_args', 'my_custom_query', 10, 2 );
