在WooCommerce订单管理员中搜索自定义字段

Question

Probably a very simple question but it leaves me clueless..

On the web if found the following code for searching a custom field on the order page. What If I wanted to scope another field?

add_filter( 'woocommerce_shop_order_search_fields', 'woocommerce_shop_order_search_order_total' );
    function woocommerce_shop_order_search_order_total( $search_fields ) {
       $search_fields[] = 'woochimp_field';
       return $search_fields;
}

Thanks

$search_fields[] Is an Array as it turns out. Every time you use $search_fields[] = 'woochimp_field'; you add to the array and makes you able to search more custom fields.

add_filter( 'woocommerce_shop_order_search_fields', 'woocommerce_shop_order_search_order_total' );
   function woocommerce_shop_order_search_order_total( $search_fields ) {
       $search_fields[] = 'woochimp_field';
       $search_fields[] = 'woochimp_field_2';    //example
       return $search_fields;
}
