我目前正在尝试将自定义结账字段中的电子邮件添加到抄送收件人列表中，以处理和完成订单电子邮件。
我已使用此代码根据购物车中的产品数量创建重复的自定义字段集。
add_action( 'woocommerce_before_order_notes', 'persons_details' );
function persons_details( $checkout ) {
$count = WC()->cart->get_cart_contents_count();
$i = 0;
for( $k=1; $k<= $count; $k++ ) {
$i++;
echo '<div><strong>'. __('Účastník ') . $i . '</strong></div>';
woocommerce_form_field( 'cstm_full_name' . $i, array(
'type' => 'text',
'class' => array('my-field-class form-row-first'),
'label' => __("Jméno a Příjmení"),
'placeholder' => __(""),
'required' => true,
), $checkout->get_value( 'cstm_full_name' . $i ));
woocommerce_form_field( 'cstm_email' . $i, array(
'type' => 'email',
'class' => array( 'my-field-class form-row-last' ),
'label' => __( "Email" ),

woocommerce_form_field( 'cstm_bdate' . $i, array(
'type' => 'date',
'class' => array('my-field-class form-row-last'),

这非常有效，可以收集数据等。使用 Divi 结帐模板时遇到了一点问题，但是当我切换回默认的 woocommerce 结帐短代码时，会收集这些字段中的数据。
现在，其中一个字段是与会者电子邮件，它收集所有课程学生的电子邮件地址。我想将这些内容包含在抄送字段中，以用于处理和已完成的订单状态电子邮件通知。
我尝试修改此代码：
add_filter( 'woocommerce_email_headers', 'student_email_notification', 20, 3 );
function student_email_notification( $header, $email_id, $order ) {
// Only for 'wc_course_order' notification
if( 'wc_course_order' != $email_id ) return $header;
$student_emails = array();
$enroll_num = 0;
// Loop though Order IDs
foreach( $order->get_items() as $item_id => $item_data ){
$course_qty = $item_data->get_quantity();
$q = 1;
while ( $q <= $course_qty){
$enroll_num++;
// Get the student full Name
$full_name = wc_get_order_item_meta( $item_id, 'First Name - '.$enroll_num, true );
$full_name .= ' ' . wc_get_order_item_meta( $item_id, 'Last Name - '.$enroll_num, true );
// Get the student email
$student_email = wc_get_order_item_meta( $item_id, 'Student Email - '.$enroll_num, true );
if( ! empty($student_email) && $full_name != ' ' )
// Format the name and the email and set it in an array
$student_emails[] = utf8_decode($full_name . ' <' . $student_email . '>'); // Add name + email to the array
$q++;
}
}
// If any student email exist we add it
if( count($student_emails) > 0 ){
// Remove duplicates (if there is any)
$student_emails = array_unique($student_emails);
// Add the emails to existing recipients
$header .= 'Bcc: ' . implode(',', $student_emails) . "\r\n";
}
return $header;
}
但无法让它发挥作用。我做错了什么？
您的代码中有多个错误。下面的代码将允许添加与会者电子邮件作为处理和已完成订单电子邮件通知的抄送：
add_filter( 'woocommerce_email_headers', 'additional_cc_recipient', 10, 3 );
function additional_cc_recipient( $headers, $email_id, $order ) {
// Only for Processing and Completed order email notifications
if( in_array($email_id, ['customer_processing_order', 'customer_completed_order']) ) {
if ( $count = $order->get_meta('cstm_items_count') ) {
$recipient = []; // initializing
for ( $i = 1; $i <= $count; $i++ ) {
$email = $order->get_meta('cstm_email'.$i);
$recipient[$email] = utf8_decode($order->get_meta('cstm_full_name'.$i) . ' <' . $email . '>');
}
$headers .= sprintf("Cc: %s\r\n", implode(',', $recipient) );
}
}
return $headers;
}
代码位于子主题的functions.php 文件中（或插件中）。应该可以。
