bbp_update_post_author_caches( array $objects = array() )
Prime post author caches.
Description Description
This function uses cache_users() to prepare the object cache for imminent requests to user objects that aren’t naturally cached by the primary WP_Query calls themselves.
This is triggered when a update_post_author_cache argument is set to true.
Parameters Parameters
- $objects
-
(Optional) Array of objects, fresh from a query
Default value: array()
Return Return
(bool) True if some IDs were cached

}
// Default value
$user_ids = array();
// Get the user IDs (could use wp_list_pluck() if this is ever a bottleneck)
foreach ( $objects as $object ) {
$object = get_post( $object );
// Skip if post does not have an author ID.
if ( empty( $object->post_author ) ) {
continue;
}
// If post exists, add post author to the array.

}
// Unique, non-zero values
$user_ids = bbp_get_unique_array_values( $user_ids );
// Bail if no IDs to prime

return false;
}
// Try to prime user caches

// Return
return true;
