Php 跟踪通过 WooCommerce 分层定价表插件进行的购买

如果项目是分级定价的，以下将向订单添加自定义字段，并将其显示在管理订单页面中:

// Track purchases made through WooCommerce Tiered Pricing Table plugin.
add_action( 'woocommerce_checkout_create_order', 'track_purchases_from_tiered_pricing_table', 10, 2 );
function track_purchases_from_tiered_pricing_table( $order, $data ) {
    $has_tiered_pricing = false; // Initializing
    
    // Loop through the cart items
    foreach ( WC()->cart->get_cart() as $item ) {
        // Loop  through extra meta keys from the product
        foreach ( wp_list_pluck( $item['data']->get_meta_data(), 'key' ) as $key ) {
            // Check for a meta_key that has 'tiered_pric' substring
            if ( strpos($key, 'tiered_pric') !== false ) {
                $has_tiered_pricing = true;
                break;
            }
        }
        // If an tiered priced item is found, flag the order
        if ( $has_tiered_pricing ) {
            $order->update_meta_data( '_has_tiered_pricing', '1' );
            break;
        }
    }
}

 // Display the purchased from Tiered Pricing Table plugin information in the admin panel
add_action('woocommerce_admin_order_data_after_billing_address', 'display_purchased_from_tiered_pricing_table_info');
function display_purchased_from_tiered_pricing_table_info($order) {
    // Display if the order has tiered priced items
    printf( '<p><strong>Purchased from Tiered Pricing Table plugin: </strong>%s</p>', 
         $order->get_meta( '_has_tiered_pricing' ) ? 'Yes' : 'No' 
    );
}

代码放在活动子主题(或活动主题)的函数.php文件中.经过测试，效果良好.

Addition:只瞄准折扣阶梯价格项目

如果您只想添加此订单元数据，则对于已计算出阶梯价格(即折扣式阶梯价格)的项目，请改用以下选项:

// Track purchases made through WooCommerce Tiered Pricing Table plugin.
add_action( 'woocommerce_checkout_create_order', 'track_purchases_from_tiered_pricing_table', 10, 2 );
function track_purchases_from_tiered_pricing_table( $order, $data ) {
    $has_tiered_pricing = false; // Initializing
    
    // Loop through the cart items
    foreach ( WC()->cart->get_cart() as $item ) {
        // Loop  through extra meta key /value pairs from the product
        foreach ( wp_list_pluck( $item['data']->get_meta_data(), 'value', 'key' ) as $key => $value ) {
            // Check for 'tiered_pricing_cart_price_calculated' meta key  
            if ( $key === 'tiered_pricing_cart_price_calculated' && $value === 'yes' ) {
                $has_tiered_pricing = true;
                break;
            }
        }
        // If an tiered priced item is found, flag the order
        if ( $has_tiered_pricing ) {
            $order->update_meta_data( '_has_tiered_pricing', '1' );
            break;
        }
    }
}

 // Display the purchased from Tiered Pricing Table plugin information in the admin panel
add_action('woocommerce_admin_order_data_after_billing_address', 'display_purchased_from_tiered_pricing_table_info');
function display_purchased_from_tiered_pricing_table_info($order) {
    // Display if the order has tiered priced items
    printf( '<p><strong>Purchased from Tiered Pricing Table plugin: </strong>%s</p>', 
         $order->get_meta( '_has_tiered_pricing' ) ? 'Yes' : 'No' 
    );
}

Addition 2:个

如何查看购物车项目(产品)保护的额外元数据(键/值对).

这个插件专门为购物车项目(产品)生成额外的元数据.

下面的代码将在购物车和 checkout 页面(only for admins)的底部显示额外的受保护元数据，这样您就可以使用正确的键/值，使我的代码(accordingly to your product settings with this plugin)正常工作:

// Displaying cart items (product) extra protected metadata in the bottom of cart and checkout pages
add_action('woocommerce_after_cart', 'display_product_extra_metadata_for_admins'); // cart
add_action('woocommerce_after_checkout_form', 'display_product_extra_metadata_for_admins'); // checkout
function display_product_extra_metadata_for_admins() {
    if( ! current_user_can('administrator') ) return; // Only admins

    echo '<pre>';
    // Loop through cart items
    foreach ( WC()->cart->get_cart() as $item ) {
        echo '<p>Name: '.$item['data']->get_name() . ' | Quantity:' .  $item['quantity'] . '</p>';
        print_r( wp_list_pluck( $item['data']->get_meta_data(), 'value', 'key' ) ); 
        echo '<br>';
    }
    echo '</pre>';
}

完成后，您可以将其删除或禁用.
