Change Add to Cart Button Position in WooCommerce

On one of the recent WordPress sites I built for a client, I was asked to change the position of the Add to Cart button in WooCommerce. You can do this by hooking into the action woocommerce_single_product_summary.

The action is defined in content-single-product.php:

<?php
        /**
         * woocommerce_single_product_summary hook
         *
         * @hooked woocommerce_template_single_title - 5
         * @hooked woocommerce_template_single_price - 10
         * @hooked woocommerce_template_single_excerpt - 20
         * @hooked woocommerce_template_single_add_to_cart - 30
         * @hooked woocommerce_template_single_meta - 40
         * @hooked woocommerce_template_single_sharing - 50
         */
        do_action( 'woocommerce_single_product_summary' );
?>

In the code above you will find a description of the hook parts, with numbers indicating priority/order. You can change the priority/order by removing and re-adding the parts like this:

remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 15 );

Add the code above to your functions.php file. Experiment with the priority to change the Add to Cart button position in WooCommerce.
