Controller::consolidate_customer_id_filters │ public static │ WC 1.0

Consolidate customer identity filter IDs into customers/customers_exclude.

When the frontend sends customer IDs via name_includes, email_includes, or username_includes, this method collects those IDs and merges them into the customers/customers_exclude params so the DataStore filters by customer_id.

Only numeric values are consolidated. String values (e.g. actual email addresses or names) are left untouched for the DataStore's exact-match filtering.

Method of the class: Controller{}

No Hooks.

Returns

array. Modified query arguments.

Usage

$result = Controller::consolidate_customer_id_filters( $args );
$args(array) (required)
Query arguments.
