This code snippet is a combination of actions and filters in WordPress that performs several tasks related to tracking orders in WooCommerce.
The add_action function is used to add an action hook when the order status changes, as well as when a post is loaded or edited. These hooks will trigger the check_private_order_notes function.
In the check_private_order_notes function, it first checks if the current screen is a shop_order post type and then retrieves the order ID. It then retrieves private order notes for that order and searches for specific text strings using a regular expression. If a match is found, it extracts the tracking number and tracking URL and updates custom fields for that order with this information.
The add_filter function is used to add a custom column called “Tracking Number” to the Orders page in the WordPress backend. The add_tracking_number_column function loops through the existing columns and adds the custom column after the “Order Status” column.
Finally, the manage_shop_order_posts_custom_column action is used to display the tracking number and URL in the custom column. The show_tracking_number_in_column function retrieves the custom fields for each order and creates a link with the tracking number and URL.
Overall, this code enables store owners to track orders more efficiently by adding a custom column with tracking information and updating custom fields with tracking numbers and URLs.
// Diese Funktion wird ausgel?st, wenn sich der Bestellstatus ?ndert
add_action('woocommerce_order_status_changed', 'check_private_order_notes', 10, 3);
// Diese Funktion wird ausgel?st, wenn der Beitrag bearbeitet wird oder neu geladen wird
add_action('load-post.php', 'check_private_order_notes');
add_action('load-post-new.php', 'check_private_order_notes');
add_action('edit_post', 'check_private_order_notes');
function check_private_order_notes() {
$screen = get_current_screen();
if ($screen->post_type == 'shop_order' && $screen->base == 'post') {
$order_id = $_GET['post'];
$order = wc_get_order($order_id);
// 1. Bestellnotizen abrufen und einer Variablen zuweisen
$private_order_notes = wc_get_order_notes(['order_id' => $order_id, 'type' => 'internal', // Nur private Notizen abrufen
]);
// 2. Durch die Notizen schlaufen und nach bestimmten Textzeichenfolgen suchen
foreach ($private_order_notes as $note) {
// 3. Tracking-Nummer und URL aus der Textzeichenfolge extrahieren
if (preg_match('/shipment is: (\d+) and can be traced at: (https?:\/\/[^\s]+)/', $note->content, $matches)) {
$tracking_number = $matches[1];
$tracking_number_url = html_entity_decode($matches[2]);
// 4. Benutzerdefinierte Felder aktualisieren
update_post_meta($order_id, 'custom_tracking_number', $tracking_number);
update_post_meta($order_id, 'custom_tracking_number_url', $tracking_number_url);
}
}
}
}
// 5. Benutzerdefinierte Spalte zur "Bestellungen" Seite im Backend hinzufügen
add_filter('manage_edit-shop_order_columns', 'add_tracking_number_column');
function add_tracking_number_column($columns) {
$new_columns = [];
foreach ($columns as $column_name => $column_info) {
$new_columns[$column_name] = $column_info;
if ($column_name == 'order_status') {
$new_columns['custom_tracking_number'] = __('Tracking Number', 'woocommerce');
}
}
return $new_columns;
}
// 6. Tracking-Nummer und URL in der benutzerdefinierten Spalte anzeigen
add_action('manage_shop_order_posts_custom_column', 'show_tracking_number_in_column');
function show_tracking_number_in_column($column) {
global $post;
if ($column == 'custom_tracking_number') {
$tracking_number = get_post_meta($post->ID, 'custom_tracking_number', true);
$tracking_number_url = get_post_meta($post->ID, 'custom_tracking_number_url', true);
echo '<a href="' . $tracking_number_url . '">' . $tracking_number . '</a>';
}
}
Depending on the carrier, you may need to modify the “regEx” used to split the Order note at specific points.
