php - 为 Woocommerce 电子邮件通知主题创建额外的变量/占位符

Question

当从自定义订单状态激活新电子邮件通知时，我有以下主题占位符选项:

"You can use the following placeholders: {order_date}, {order_number}, {order_status}, {billing_first_name}, {billing_last_name}, {billing_company}, {blogname}, {site_title}"

有没有办法为其他字段创建新的占位符？基本上，我创建了一个名为 test_pw 的新隐藏字段，我希望能够将 {billing_email} 和 {test_pw} 添加到我的自定义电子邮件中。

我已经尝试使用此代码，但我不确定如何格式化它。

// Only for woocommerce versions 3.2 + (up to 3.2)
add_filter( 'woocommerce_email_format_string' , 'filter_email_format_string', 20, 2 );
function filter_email_format_string( $string, $email ) {
// Get the instance of the WC_Order object
$order = $email->object;

// Additional wanted placeholders in the array of find / relace pairs
$additional_placeholders = array(
    '{custom_one}'      => __('my replacement one','woocommerce'),
    '{billing_email}'   => $order->get_billing_email(),
    '{test_pw}'   => $order->get_test_pw(),
);

// return the clean string with new replacements
return str_replace( array_keys( $additional_placeholders ), array_values( $additional_placeholders ), $string );
}

这是一个示例，将向您展示如何为电子邮件通知添加新的占位符主题:

// Only for woocommerce versions 3.2 + (up to 3.2)
add_filter( 'woocommerce_email_format_string' , 'filter_email_format_string', 20, 2 );
function filter_email_format_string( $string, $email ) {
    // Get the instance of the WC_Order object
    $order = $email->object;

    // Additional wanted placeholders in the array of find / relace pairs
    $additional_placeholders = array(
        '{custom_one}'      => __('my replacement one','woocommerce'),
        '{shipping_city}'   => $order->get_shipping_city(),
        '{yudu_pw}'         => $order->get_meta( 'yudu_pw' ), // <=== HERE
    );

    // return the clean string with new replacements
    return str_replace( array_keys( $additional_placeholders ), array_values( $additional_placeholders ), $string );
}
