WooCommerce comments_template Filter Not Firing

Okay, for anyone looking to include the WooCommerce review tab not on an actual single-product page here’s the secret sauce:

In your template file, you need:

global $withcomments;
$withcomments = true;

Then add a filter for the comments template:

//add filter to use our custom review template
add_filter('comments_template','{{YOUR_HELPER_FUNCTION}}');

/**
* Hook function for using custom quickview review template
* @return [string] [file path to the template]
*/
function YOUR_HELPER_FUNCTION(){
    $template = LCS_DIR . "../templates/tmpl-single-product-reviews.php";
    if ( file_exists( $template ) )
        return( $template );
}

$template is the full file path to the template file you want to use.

BadaBing and you’re done!
