根据多个类别为 WooCommerce 订单号添加前缀 [英] Adding prefix to WooCommerce order number based on multiple categories

问题描述

根据我之前的问题，我正在使用 如果订单包含来自特定产品类别的商品，则为 WooCommerce 订单号添加前缀 anwser代码.

From my previous question I am using Adding prefix to WooCommerce order number if order has items from a specific product category anwser code.

现在我想把这个功能扩展到更多的类别，但我似乎找不到.

Now I want to extend this function for more categories, but I can't seem to find it out.

现在我想为其他类别添加更多 if 语句.我在想这样的事情:

Now I want to add more if statements for the other categories. I am thinking of something like this:

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;

}

有人可以帮忙吗?

推荐答案

从 添加前缀到 WooCommerce 订单号 if order 中的代码有来自特定产品类别的项目，您可以使用多个类别的答案代码:

To extend the code from Adding prefix to WooCommerce order number if order has items from a specific product category answer code for multiple categories you can use:

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 );
