【中文标题】根据多个类别为 WooCommerce 订单号添加前缀

【英文标题】：Adding prefix to WooCommerce order number based on multiple categories

【发布时间】：2021-04-14 09:07:54

【问题描述】：

根据我之前的问题，我正在使用Adding prefix to WooCommerce order number if order has items from a specific product category anwser 代码。

现在我想把这个功能扩展到更多的类别，但我似乎找不到。

现在我想为其他类别添加更多 if 语句。我正在考虑这样的事情：

if ('category of first product in appearing in cart' === 'category id / category name') 

    $prefix = 'AB-';
    $new_order_id = $prefix . $order_id;
    return $new_order_id;


elseif ('category of first product in appearing in cart' === 'category id / category name') 

    $prefix = 'CD-';
    $new_order_id = $prefix . $order_id;
    return $new_order_id;


elseif ('category of first product in appearing in cart' === 'category id / category name') 

    $prefix = 'EF-';
    $new_order_id = $prefix . $order_id;
    return $new_order_id;

谁能帮忙？

【参考方案1】：

要将代码从Adding prefix to WooCommerce order number if order has items from a specific product category 扩展为多个类别的答案代码，您可以使用：

function filter_woocommerce_order_number( $order_number, $order ) 
    // Loop through order items
    foreach ( $order->get_items() as $item ) 
        // Product ID
        $product_id = $item->get_variation_id() > 0 ? $item->get_variation_id() : $item->get_product_id();

        // Has term (product category)
        if ( has_term( array( 'categorie-1', 'categorie-2', 15, 16 ), 'product_cat', $product_id ) ) 
            return 'AB-' . $order_number;
         elseif ( has_term( array( 'categorie-3', 'categorie-4' ), 'product_cat', $product_id ) ) 
            return 'CD-' . $order_number;
         elseif ( has_term( array( 'categorie-5', 'categorie-6' ), 'product_cat', $product_id ) ) 
            return 'EF-' . $order_number;
        
    
    
    return $order_number;

add_filter( 'woocommerce_order_number', 'filter_woocommerce_order_number', 10, 2 );

使用if/elseif/else，您可以添加任意数量的条件
