从 WooCommerce 中的父变量 product 设置订单项目永久链接

Question

On the thank you page and in order emails, the permalink for variable products always links directly to the product variation instead of the parent product itself, eg, https://mystore.com/some-product/?attribute_color=red . I need the permalink to reflect the product and not the variation, eg https://mystore.com/some-product/ .

I've tried the following:

$parent_id = $product->get_parent_id();
$slug = $product->get_permalink($parent_id);

The variable

$parent_id

returns correctly, but

$slug

is always the variation permalink. What am I missing? Alternatively, I've tried to retrieve the post name of the parent like so

$parent_id = $product->get_parent_id();
$slug = $product->get_post_name($parent_id);

but this throws an error and the thank you page only partially renders.

You don't need to override any template file, just use the following hooked function, to replace the product variation permalink, by the parent variable product permalink on all orders:

add_filter( 'woocommerce_order_item_permalink', 'filter_order_item_permalink_callback', 10, 3 );
function filter_order_item_permalink_callback( $product_permalink, $item, $order ) {

    // For product variations
    if( $item->get_variation_id() > 0 ){
        $product    = $item->get_product();
        $is_visible = $product && $product->is_visible();

        // Get the instance of the parent variable product Object
        $parent_product = wc_get_product( $item->get_product_id() );

        // Return the parent product permalink (if product is visible)
        return $is_visible ? $parent_product->get_permalink() : '';
    }
    return $product_permalink;
}

Code goes in functions.php file of your active child theme (or active theme). Tested and work.

For email notifications

WooCommerce doesn't display, by default, the product permalink in the email notifications…

To display the product permalink on email notifications, use the following:

add_filter( 'woocommerce_order_item_name', 'filter_order_item_name_callback', 10, 3 );
function filter_order_item_name_callback( $item_name, $item, $is_visible ) {

    // On emails notifications only
    if( ! is_wc_endpoint_url() > 0 ) {
        $product = $item->get_product();

        // For product variation type
        if( $item->get_variation_id() > 0 ){

            // Get the instance of the parent variable product Object
            $parent_product = wc_get_product( $item->get_product_id() );

            // The parent product permalink (if product is visible)
            $product_permalink = $parent_product->get_permalink();
        } 
        // For other item (product) type
        else {
            $product_permalink = $product->get_permalink();
        }

        return sprintf( '<a href="%s">%s</a>', $product_permalink, $item_name );
    }
    return $item_name;
}

Code goes in functions.php file of your active child theme (or active theme). Tested and work.
