在 WooCommerce 管理员订单预览中显示供应商商店名称 (Dokan)

Question

我们通过以下方式在每个订单的管理订单详细信息中添加供应商信息：

• WooCommerce show vendor store-name (Dokan) in admin order details overview

现在我还想在订单预览中添加此信息。我找到了这个答案

• Display custom data on Woocommerce admin order preview

我们将钩子更改为woocommerce_admin_order_preview_end，但现在当我们想要打开预览时什么也没发生。

我们是否必须调整整个代码以使其适用于订单预览，或者为什么我们的方法不起作用？

function action_woocommerce_admin_order_vendor_data( $order ) {
    // Empty array
    $shop_names = array();

    // Output
    echo '<strong>' . __( 'Vendor(s): ', 'woocommerce' ) . '</strong>';
    
    // Loop through order items
    foreach ( $order->get_items() as $item ) {
        // Get product object
        $product = $item->get_product();
        
        // Author id
        $author_id = $product->post->post_author;
        
        // Shopname
        $vendor = dokan()->vendor->get( $author_id );
        $shop_name = $vendor->get_shop_name();
        
        // OR JUST USE THIS FOR SHOPNAME
        // Shop name
        // $shop_name = dokan()->vendor->get( $author_id )->get_shop_name();
        
        // NOT in array
        if ( ! in_array( $shop_name, $shop_names ) ) {
            // Push to array
            $shop_names[] = $shop_name;

            // Output
            echo $shop_name . ', ';
        }
    }
}
add_action('woocommerce_admin_order_preview_end', 'action_woocommerce_admin_order_vendor_data', 10, 1 );

Answer 1

正如您提到的链接中已经解释的那样（由LoicTheAztec）。您无法获取 order 对象，因为它是通过 Ajax 加载特定数据的模板，并且 woocommerce_admin_order_preview_start 操作挂钩没有参数

相反，过滤器钩子woocommerce_admin_order_preview_get_order_details 将允许您首先添加一些自定义数据，您将能够通过woocommerce_admin_order_preview_start 或woocommerce_admin_order_preview_end 操作钩子调用和显示它

所以你得到：

// Add custom order meta data to make it accessible in order preview template
function filter_woocommerce_admin_order_preview_get_order_details( $data, $order ) {
    // Empty array
    $shop_names = array();
    
    // Loop through order items
    foreach ( $order->get_items() as $item ) {
        // Get product object
        $product = $item->get_product();
        
        // Author id
        $author_id = $product->post->post_author;
        
        // Shopname
        $vendor = dokan()->vendor->get( $author_id );
        $shop_name = $vendor->get_shop_name();
        
        // OR JUST USE THIS FOR SHOPNAME
        // Shop name
        // $shop_name = dokan()->vendor->get( $author_id )->get_shop_name();
        
        // NOT in array
        if ( ! in_array( $shop_name, $shop_names ) ) {
            // Push to array
            $shop_names[] = $shop_name;
        }
    }
    
    // NOT empty
    if ( ! empty ( $shop_names ) ) {
        // Store the value in the data array
        $data['shop_names'] = implode( '<br>', $shop_names );
    }

    return $data;
}
add_filter( 'woocommerce_admin_order_preview_get_order_details', 'filter_woocommerce_admin_order_preview_get_order_details', 10, 2 );

// Display custom values in order preview
function action_woocommerce_admin_order_preview_start() {
    // Output
    echo '<div class="wc-order-preview-wrapper">';
    echo '<div class="wc-order-preview-shop-names" style="padding:1.5em 1.5em 0; box-sizing:border-box;">';
    
    // H2
    echo '<h2>' . __( 'Vendor(s)', 'woocommerce' ) . '</h2>';
    
    // Call the stored value and display it
    echo '{{{ data.shop_names }}}';
    
    // Close
    echo '</div></div>';
}
add_action( 'woocommerce_admin_order_preview_start', 'action_woocommerce_admin_order_preview_start', 10, 0 );
