With the removal of the global $product variable from the Add to Cart with Options block on #9457 , follow-up changes are required to ensure this block works as expected.

Initially, this block relied on the native WooCommerce's templates for rendering the Add to Cart button with Options button. The problem is those templates all rely exclusively on the global $product variable for generating content, and in the absence of it, a Fatal error is thrown:

Call to a member function is_purchasable() on string in /srv/htdocs/wp-content/plugins/woocommerce/templates/single-product/add-to-cart/simple.php:22

Based on the outcome of the discussion on #9457 , an altered and consolidated version of all add-to-cart form templates needs to be developed for rendering the Add to Cart with Options block.

The consolidated templates should include:

• woocommerce/templates/single-product/add-to-cart/external.php
• woocommerce/templates/single-product/add-to-cart/grouped.php
• woocommerce/templates/single-product/add-to-cart/simple.php
• woocommerce/templates/single-product/add-to-cart/variable.php
• woocommerce/templates/single-product/add-to-cart/variation-add-to-cart-button.php
