为Woocommerce电子邮件通知主题创建其他变量/占位符 [英] Create additional variables/placeholders for Woocommerce email notifications subject

问题描述

从自定义订单"状态激活新的电子邮件通知时，主题"占位符具有以下选项:

When activating new email notifications from Custom order statuses I have this options for Subject placeholders:

您可以使用以下占位符:{order_date}，{order_number}，{order_status}，{billing_first_name}，{billing_last_name}，{billing_company}，{blogname}，{site_title}"

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

是否可以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，并且希望能够将{billing_email}和{test_pw}添加到我的自定义电子邮件中.

Is there a way of creating new placeholders for other fields? Basically, I have created a new hidden field called test_pw and I want to be able to add {billing_email} and {test_pw} to my custom emails.

我已经尝试过建议使用此代码，但是我不确定如何设置其格式.

I have tried with this code kindly suggested but I am not sure how to format it.

// 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 );
}

推荐答案

下面是一个示例，它将向您展示如何为电子邮件通知添加新的占位符.

Here is an example that will show you how to add new placeholders for email notifications Subject:

// 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 );
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，并且仅适用于Woocommerce 3.2及更高版本……
