Woocommerce訂閱掛鉤/過濾器不工作

Question

我已經寫了這個函數，並把它放在我的functions.php但由於某種原因它不會觸發，我已經嘗試過它作爲一個動作和過濾器，但沒有運氣。

// ADD £40 ON SUCCESFUL SUBSCRIPTION PAYMENT (EXAMPLE 2) 
function custom_add_funds_two($user_id) { 

    // get current user's funds 
    $funds = get_user_meta($user_id, 'account_funds', true); 

    // add £40 
    $funds = $funds + 40; 

    // add funds to user 
    update_user_meta($user_id, 'account_funds', $funds); 

} 
add_filter('processed_subscription_payment','custom_add_funds_two'); 

Answer 1

WooCommerce文檔建議，你可能會後的掛鉤可能是：

woocommerce_subscription_payment_complete 

或

woocommerce_subscription_renewal_payment_complete 

Source

所以我會嘗試：

add_action('woocommerce_subscription_payment_complete','custom_add_funds_two');
