WooCommerce Subscriptions - Get product of a specific subscription

问题

Is there a way to get from $product from $subscription?

Thanks to this post, I know that from $subscription I can get $order:

$order = $subscription->order;

Is this also possible?

$product = $subscription->product;

Or:

$product = $order->product;

回答1:

It is possible to get the products from either the Subscription or the matching order, as a subscription object is an extension of the WC_Order class.

$subscription_products = $subscription->get_items();
$order_products = $subscription->order->get_items();

In most situations where you provide subscription services, both of these will be equivalent or $order_products should at least contain all products found within $subscription_products.

A notable exception is when you create a subscription manually; no order will be attached to the subscription, so $subscription->order may not be a valid WC_Order object.

Get product from woocommerce subscription full code with examples of use:

if ( sizeof( $subscription_items = $subscription->get_items() ) > 0 ) {
    foreach ( $subscription_items as $item_id => $item ) {
        $product = $item->get_product();

        //Examples of use
        $product->get_id();
        $product->get_sku();
        $product->get_image('post-thumbnail', ['class' => 'alignleft'], false); // main image

        $product_id = wcs_get_canonical_product_id( $item ); // get product id directly from item
    }
}

Yes, if you have a "subscription ID" you can get an object like this:

$subscription = new WC_Subscription( $the_id );

When you already have $subscription object:

$related_orders_ids_array = $subscription->get_related_orders();

Then loop through array of related orders.

foreach ( $related_orders_ids_array as $order_id ) {

    $order = new WC_Order( $order_id );
    $items = $order->get_items();

then if you loop through order items, you can access product information:

    foreach ( $items as $product ) {

        var_dump( $product );

    }

}
