Inclusion in the WooCommerce system

WooCommerce product pages have reviews and not comments.
You can add comments using the comments_template function which will display the social comments on product pages.

I did something for a client which add a product tab with the comments inside it, something like this:

add_filter( 'woocommerce_product_tabs', 'add_social_comments_tab' );
function add_social_comments_tab($tabs){

	$tabs[ 'comments' ] = array(
		'title'    => __( 'Comments' ),
		'priority' => 25,
		'callback' => 'get_social_comments'
	);
}

function get_social_comments(){
	global $withcomments;
	$withcomments = 1;
	comments_template();
}

Also you can use a special discussing and commenting plugin for WooCommerce Products called WooDiscuz. It’s created and designed especially for WooCommerce Products
