Can not switch the queried post in pre_get_posts hook

Huh. I double-checked. On my local server, this bit of code successfully changes the post: function test_redirect() { global $wp_query; $wp_query->set(‘page_id’, 5); } add_action(‘pre_get_posts’, ‘test_redirect’); You’re going to have to do a bit of debugging. On a dev server, var_dump the $wp_query variable a few key places to check that it has what you expect … Read more

If orderby parameter using pre_get_posts is the same for multiple posts what fallback does the query use?

For identical values they’ll be in whatever order they’re returned by the database engine, which would typically be the order they were inserted in the database.

WordPress custom search form with pre_get_posts not work

Now as for the main question: the main Query is not modified, the CPT … Read more

Displaying custom post type on category pages but not on blog listings

This may be overly simplistic, but have you tried changing is_home() to is_category(), in this line: if ( is_home() && false == $query->query_vars[‘suppress_filters’] ) i.e. change it to this: if ( is_category() && false == $query->query_vars[‘suppress_filters’] ) Worth a shot, anyway…

How to use pre_get_posts?

Remove all query code from the template and just leave the default loop. In your example code you’re overwriting the query in the template, in the code you pasted in the comments, you’re running an entirely new query. These are both unnecessary when using pre_get_posts. Put your pre_get_posts code in functions.php. You don’t have to … Read more

Sort custom post types by last name in the backend

pre_get_post filter returns results when there should not be

Assuming that you get an empty array for $post_ids if there are no matching posts, I think this is wrong: if ( $post_ids ) {} Because the array exists, but is empty. Try to check for an empty array: if ( ! empty( $post_ids ) ) {}

Can’t sort order of wp_query with 2 meta keys

As you can read in Codex about orderby and the WP_Query, you can use multiple orderby values as well: ‘orderby’ => ‘name meta_value’ simply by using a space in between.
