I'm trying to disable the completed order email only if the customer selects the "Retirada no local" shipping method.
I found the following code, which disables email for all shipping methods except one - it's not what I need, but it might help:
function filter_woocommerce_email_recipient_new_order( $recipient, $order = false ) {
if ( ! $order || ! is_a( $order, 'WC_Order' ) ) return $recipient;
// 获取配送方式
$shipping_method = $order->get_shipping_method();
// 不等于（注意：这应该根据您网站语言中的配送方式进行调整）
// 例如：荷兰语中的“Afhalen”等...
if ( $shipping_method != 'Local Pickup' ) {
$recipient = '';
}
return $recipient;
}
add_filter( 'woocommerce_email_recipient_new_order', 'filter_woocommerce_email_recipient_new_order', 10, 2 );```

Change the version of the code you provided to one that disables the "Order Completed" customer email when shipping method is "Retirada no local"
function disable_completed_order_customer_email_for_retirada( $recipient, $order = false ) { if ( ! $order || ! is_a( $order, 'WC_Order' ) ) return $recipient; // 获取配送方式 $shipping_method = $order->get_shipping_method(); // 仅在配送方式为“Retirada no local”时禁用 if ( $shipping_method === 'Retirada no local' ) { $recipient = ''; } return $recipient; } add_filter( 'woocommerce_email_recipient_customer_completed_order', 'disable_completed_order_customer_email_for_retirada', 10, 2 );Please note that your shipping method must exactly match the words and capital letters of the phrase "Retirada no local" for this code to be valid.
