What is WordPress Hook: users_pre_query

The users_pre_query hook in WordPress is used to modify the user query before it is executed. This hook allows developers to alter the parameters of the user query, such as the user role, meta data, or search parameters.

Understanding the Hook: users_pre_query

The users_pre_query hook is located within the WP_User_Query class in WordPress. It is called before the user query is executed, giving developers the opportunity to modify the query parameters.

Hook Parameters (if applicable): users_pre_query

The users_pre_query hook accepts the $user_query parameter, which is an instance of the WP_User_Query class. Developers can modify the query parameters using methods available within the WP_User_Query class, such as set or get methods for user roles, meta queries, or search parameters.

Hook Doesn’t Work: users_pre_query

If the users_pre_query hook doesn’t work as expected, it may be due to incorrect implementation or conflicting code. Developers should ensure that the hook is added to the correct action or filter, and that any modifications to the user query are done properly within the hook function.

Best Practices & Usage Notes (if applicable): users_pre_query

When using the users_pre_query hook, it’s important to consider the performance implications of modifying the user query. Making extensive or inefficient modifications to the user query can impact the overall performance of the website. It’s recommended to use this hook sparingly and with careful consideration of the query modifications.

Usage Example: users_pre_query

“`php
function modify_user_query( $user_query ) {
// Modify user query parameters
$user_query->set( ‘role’, ‘subscriber’ );
}
add_action( ‘users_pre_query’, ‘modify_user_query’ );
“`
In this example, the users_pre_query hook is used to modify the user query to only retrieve users with the ‘subscriber’ role. This demonstrates a basic use case of the users_pre_query hook within WordPress functions.
