I had a similar issue and maybe this is also helpful when pagination is only working sometimes: e.g. /page/1/ and /page/2/ are working and /page/3/ not. Result: Error 404. Problem is: default value (12 items each page) for posts_per_page (WordPress Settings/Reading) is loaded always from database before the template is loaded. So $args=[‘posts_per_page’ => 1] … Read more
How to offset main query without affecting other queries and backend
Display Specific Posts at Start of Loop
I know this is an old question, but it is a bit confusing and hopefully will help someone. The reason that `$query->set doesn’t work is because the query has already been parsed and now we need to also update the tax_query object also. Here is how I did it: function my_tax_query( $query ) { $package_id … Read more
Apply pre_get_posts filter in a certain moment (just for a particular block of posts)
If you’re using global loop for displaying the posts, then you can easily modify which posts are shown using pre_get_posts action. function restrict_categories_for_user( $query ) { if ( ! is_admin() && $query->is_main_query() && get_current_user_id() ) { $user = wp_get_current_user(); if ( in_array( ‘viewer_a’, (array) $user->roles ) ) { // The user has the “viewer_a” role … Read more
When using LIKE clause, you should be using % to the start and end of the value to make it match with the existing values.

I think you need to first define property_com_listing_type as a query: https://codepen.io/the_ruther4d/post/custom-query-string-vars-in-wordpress Then you can rewrite the urls with add_rewrite_rule (do not forget to save permalinks after change): https://codex.wordpress.org/Rewrite_API/add_rewrite_rule with a regex like ^category/([^/]+)/([^/]+)/? Then you can modify the query using pre_get_posts: https://developer.wordpress.org/reference/hooks/pre_get_posts/
I can’t use is_singular( ‘my_post_type’ ) in pre_get_posts because the queried object is not set at this point. I can use instead the post_type query parameter.
