BP_Notifications_Notification::get_meta_query_sql( array $meta_query = array() )
Get the SQL for the ‘meta_query’ param in BP_Notifications_Notification::get().
Description Description
We use WP_Meta_Query to do the heavy lifting of parsing the meta_query array and creating the necessary SQL clauses. However, since BP_Notifications_Notification::get() builds its SQL differently than WP_Query, we have to alter the return value (stripping the leading AND keyword from the ‘where’ clause).
Parameters Parameters
- $meta_query
-
(Optional) An array of meta_query filters. See the documentation for WP_Meta_Query for details.
Default value: array()
Return Return
(array) $sql_array 'join' and 'where' clauses.
