Set Variable Product Price before adding in WooCommerce order programatically

Question

In Cart, I added a button to create quotation orders. I am using a quantity range pricing plugin so all of my variable products have a wide range of pricing.

Eg. Product A's item cost is $5 when quantity is below 100. Item cost is $3 when quantity is 100 to 199.

My cart displays the correct item cost and I manage to retrieve each cart item's product price. However, I am unable to set the variation price and add the data into order.

Does anyone knows how can I solve this?

        // Now we create the order
            $order = wc_create_order();

        // add products from cart to order
        $items = WC()->cart->get_cart();
        foreach($items as $item => $values) {

            $_product   = apply_filters( 'woocommerce_cart_item_product', $values['data'], $values, $item );

            $tieredPrice = WC()->cart->get_product_price($_product);

            $product_id = $values['product_id'];

            $product = wc_get_product($product_id);
            $quantity = (int)$values['quantity'];

            $var_id = $values['variation_id'];

            $variationsArray = array($values['variation']);
            $var_product = new WC_Product_Variation($var_id);
            $var_product->set_variation_price($tieredPrice); //how do I set variation price?

            $order->add_product($var_product, $quantity, $variationsArray);
        }

Thank you in advance.

In cart $values['data'] is already an instance Of the WC_Product object, so for a product variation it is directly an instance of the WC_Product_Variation object, so this will be simple now.

The set_variation_price() method doesn't exist for WC_Product objects, it is set_price()…

So your revisited code will be:

// Now we create the order
$order = wc_create_order();

// Add products from cart to order
$cart = WC()->cart; // cart object
foreach( $cart->get_cart() as $cart_item_key => $cart_item) {
    $product   = $cart_item['data']; // An instance of the WC_Product object
    $qty = intval($cart_item['quantity']); // The quantity
    $tierced_price = $cart->get_product_price($_product); // your "tierced" price
    $product->set_price( $tierced_price ); // <==  <==  <==  <==  <==  <==  SET THE PRICE
    $args = array( $cart_item['variation'] ); // empty if not a variation

    $order->add_product( $product, $qty, $args );
}

This should work
