问题
I'm having a hard time printing my custom field value to the email notifications, order admin and thank you page. I've browsed through StackOverflow, tried every single answer I found but unfortunately not working and I couldn't figure out the problem: I am trying to pass the value of the additional checkout field, it only prints the strong label with a blank value, and in the emails nothing shows, here is my code so far:
//new pickup location checkout field
add_action( 'woocommerce_before_order_notes', 'pickup_location_custom_checkout_field' );
function pickup_location_custom_checkout_field( $checkout ) {
echo '<div><h3>' . __('Pick-up location') . '</h3>';
woocommerce_form_field( 'pick_up_location', array(
'type' => 'text',
'class' => array('notes'),
'label' => __('<span style="color:red">[IMPORTANT]</span> Where should we meet you?'),
'placeholder' => __('Please enter your accomodation name or the nearest pick-up point if not accessible by car'),
'required' => true,
), $checkout->get_value( 'pick_up_location' ));
echo '</div>';
}
// Save the pickup location data to the order meta
add_action( 'woocommerce_checkout_create_order', 'pickup_location_checkout_field_update_order_meta' );
function pickup_location_checkout_field_update_order_meta( $order_id ) {
if (!empty($_POST['pick_up_location'])) {
update_post_meta( $order_id, 'Pick-up location', sanitize_text_field( $_POST['pick_up_location']));
}
}
// Display 'pickup location' on the order edit page (backend)
add_action( 'woocommerce_admin_order_data_after_shipping_address', 'pickup_location_checkout_field_order_page', 10, 1 );
function pickup_location_checkout_field_order_page($order){
global $post_id;
$order = new WC_Order( $post_id );
echo '<p><strong style="color:red">'.__('Pickup Location').':</strong> ' . get_post_meta($order->get_id(), '_pick_up_location', true ) . '</p>';
// Display 'pickup location' in "Order received" and "Order view" pages (frontend)
add_action( 'woocommerce_order_details_after_order_table', 'display_client_pickup_data_in_orders', 10 );
function display_client_pickup_data_in_orders( $order ) {
global $post_id;
$order = new WC_Order( $post_id );
echo '<p><strong style="color:red">'.__('Pickup Location').':</strong> ' . get_post_meta($order->get_id(), '_pick_up_location', true ) . '</p>';
}
// Display 'pickup location data' in Email notifications
add_filter( 'woocommerce_email_order_meta_fields', 'display_client_pickup_data_in_emails', 10, 3 );
function display_client_pickup_data_in_emails( $fields, $sent_to_admin, $order ) {
$fields['Pickup Location'] = array(
'label' => __( 'Pickup Location' ),
'value' => get_post_meta( $order->get_id(), 'pick_up_location', true ),
);
return $fields;
}
No matter what I try, the code only prints the label without any value from the checkout form. I know this question has been asked many times, but I tried every single answer for over 6 days without any luck. I also need to mention that I am using Woocommerce Bookings in this project. Thanks for your help

Go through your code step by step
update_post_meta( $order_id, 'Pick-up location', sanitize_text_field( $_POST['pick_up_location']));
echo '<p><strong style="color:red">'.__('Pickup Location').':</strong> ' . get_post_meta($order->get_id(), '_pick_up_location', true ) . '</p>';
'value' => get_post_meta( $order->get_id(), 'pick_up_location', true ),
You use Pick-up location, _pick_up_location & pick_up_location as meta_key
while this should be 3x the same value.
You also miss a closing tag by pickup_location_checkout_field_order_page function.
You also use wrong parameters with some hooks, etc..
Try this instead
//new pickup location checkout field
add_action( 'woocommerce_before_order_notes', 'pickup_location_custom_checkout_field' );
function pickup_location_custom_checkout_field( $checkout ) {
echo '<div><h3>' . __('Pick-up location') . '</h3>';
woocommerce_form_field( 'pick_up_location', array(
'type' => 'text',
'class' => array('notes'),
'label' => __('<span style="color:red">[IMPORTANT]</span> Where should we meet you?'),
'placeholder' => __('Please enter your accomodation name or the nearest pick-up point if not accessible by car'),
'required' => true,
), $checkout->get_value( 'pick_up_location' ));
echo '</div>';
}
// Save the pickup location data to the order meta
add_action( 'woocommerce_checkout_create_order', 'pickup_location_checkout_field_update_order_meta', 10, 2 );
function pickup_location_checkout_field_update_order_meta( $order, $data ) {
if ( !empty( $_POST['pick_up_location']) ) {
$order->update_meta_data( '_pick_up_location', sanitize_text_field( $_POST['pick_up_location'] ) ); // Order meta data
}
}
// Display 'pickup location' on the order edit page (backend)
add_action( 'woocommerce_admin_order_data_after_shipping_address', 'pickup_location_checkout_field_order_page', 10, 1 );
function pickup_location_checkout_field_order_page( $order ) {
$pick_up_location = $order->get_meta( '_pick_up_location' );
echo '<p><strong style="color:red">'.__('Pickup Location').':</strong> ' . $pick_up_location . '</p>';
}
// Display 'pickup location' in "Order received" and "Order view" pages (frontend)
add_action( 'woocommerce_order_details_after_order_table', 'display_client_pickup_data_in_orders', 10 );
function display_client_pickup_data_in_orders( $order ) {
$pick_up_location = $order->get_meta( '_pick_up_location' );
echo '<p><strong style="color:red">'.__('Pickup Location').':</strong> ' . $pick_up_location . '</p>';
}
// Display 'pickup location data' in Email notifications
add_filter( 'woocommerce_email_order_meta_fields', 'display_client_pickup_data_in_emails', 10, 3 );
function display_client_pickup_data_in_emails( $fields, $sent_to_admin, $order ) {
