（WooCommerce）检查客户是否订购了超过一定数量的订单或花了一定数量？

Question

Is there a way I can set a conditional statement to show a message to customers that have already made a certain number of orders or spent more than a certain amount of money on my store?

I basically want to offer a site-wide discount for valued customers, which I have already set up a system for, but ideally I'd like to show a form where users can apply for this discount, but to prevent everyone from applying I'd like to only show it to repeat customers.

Turns out that we can steal... er borrow... a query for orders right out of the WooCommerce source. We just need to modify the posts_per_page parameter to -1 so that it will query all posts.

This has the potential to chew up resources... so 1. I suggest only running it for logged in users. 2. Maybe only retrieve the number of posts you want to limit your coupon to (aka... 5 orders gets you a discount, only retrieve 5 posts) and 3. possibly even cache the value either in a transient or maybe even keep track of it as user meta. That last one is a bit trickier than I want to get into now so

if ( is_user_logged_in() ) {

    $number_of_orders = 10;

    $customer_orders = get_posts( apply_filters( 'woocommerce_my_account_my_orders_query', array(
        'numberposts' => $number_of_orders,
        'meta_key'    => '_customer_user',
        'meta_value'  => get_current_user_id(),
        'post_type'   => wc_get_order_types( 'view-orders' ),
        'post_status' => array_keys( wc_get_order_statuses() )
    ) ) );

    if ( $customer_orders && count( $customer_orders > $number_of_orders ) ){
        // whoa you've got more than 10 orders
    }

}
