WooCommerce- Change variables (eg Size) at checkout/review order page
<p>I'm trying to create a one-click-checkout page, and the product variables (eg Size, colour) needs to feature at the checkout page itself.</p>

<p>I have modified the "review-order.php" template without success.</p>

<p>My attempt was-</p>

<p><code>&lt;?php echo($available_variations = $product-&gt;get_available_variations();) ?&gt;</code></p>

<p>How can I add an option to change the product variable at the "review-order.php" page?</p>
