WordPress – I got 405 Error on order edit page in WooCommerce. Maybe I use a wrong hook?

I add a custom meta box on order edit page and trying to save data but got 405 error (the data saved successfully and code seems to be work):

// Adding Meta container admin shop_order pages
add_action( 'add_meta_boxes', function() {
    add_meta_box(
        'tracking_field',
        __('Tracking number','woodmart-child'),
        'add_tracking_field_content',
        wc_get_page_screen_id('shop-order'),
        'side',
        'core'
    );
});

// Adding Meta field in the meta container on admin shop_order pages
function add_tracking_field_content( $order ) {
    
    echo '<input type="text" style="width:100%" name="ttn_number" placeholder="'. __('Tracking number', 'woodmart-child') .'" value="'. $order->get_transaction_id() .'">';
    echo '<input type="hidden" name="ttn_nonce" value="'. wp_create_nonce() .'">';
    
}

add_action( 'woocommerce_update_order', 'save_tracking_number', 10, 2 );
function save_tracking_number($order_id, $order){
    
    if ( ! isset($_REQUEST['ttn_nonce']) && ! wp_verify_nonce($_REQUEST['ttn_nonce']) ) {
        return $order_id;
    }
    
    $ttn_number = sanitize_text_field( $_POST['ttn_number'] );
    $order->set_transaction_id($ttn_number);
    if(!empty($ttn_number)) {
        $order->update_status('wc-arrival-shipment', '', true);
    }
    $order->save();

}

I use WooCommerce with HPOS activated function, so the default hook save_post_shop_order not working for me.

I found woocommerce_update_order hook, but I think it was a bad idea or it just not allowed to use $order->set_transaction_id().

    Setting custom transaction ID might not be the best option. You can add a custom meta box in the order. Also changed the nonce handling a bit and added the action.

    add_action('add_meta_boxes', function () {
    add_meta_box(
        'tracking_field',
        __('Tracking number', 'woodmart-child'),
        'add_tracking_field_content',
        wc_get_page_screen_id('shop-order'),
        'side',
        'core'
    );
});


function add_tracking_field_content($order) {
    echo '<input type="text" style="width:100%" name="ttn_number" placeholder="' . __('Tracking number', 'woodmart-child') . '" value="' . esc_attr($order->get_meta('_ttn_number')) . '">';
    echo '<input type="hidden" name="ttn_nonce" value="' . esc_attr(wp_create_nonce('ttn_nonce')) . '">';
}

add_action('woocommerce_process_shop_order_meta', 'save_tracking_number');
function save_tracking_number($order_id) {
    if (!isset($_POST['ttn_nonce']) || !wp_verify_nonce($_POST['ttn_nonce'], 'ttn_nonce')) {
        return;
    }

    $ttn_number = sanitize_text_field($_POST['ttn_number']);
    update_post_meta($order_id, '_ttn_number', $ttn_number);

    if (!empty($ttn_number)) {
        $order = wc_get_order($order_id);
        $order->update_status('wc-arrival-shipment', '', true);
    }
}

    To fix the 405 error when saving data in a custom WooCommerce meta box:

    1. Check HTTP Method: Ensure you’re using the POST method in your form or request.
    2. Verify Server Configuration: Make sure your server allows the POST method. This might involve checking .htaccess or Nginx configurations.
    3. Review Hook Usage: Confirm that woocommerce_update_order is the correct hook and that nonce validation and data sanitization are properly implemented.
    4. Check HPOS Compatibility: Ensure High-Performance Order Storage (HPOS) doesn’t interfere with saving the meta box data.
    5. Enable Debugging: Turn on WordPress debugging to identify any specific issues in the wp-content/debug.log file.
    6. Permissions Check: Make sure the user role has the necessary permissions to edit orders
    7. Test in a Clean Environment: Disable other plugins and use a default theme to rule out conflicts.

    This should help identify and resolve the issue with the 405 error.
