Shipping cost after the discount

As I didn’t have any reply from Booster plugin support and I haven’t solve my problem yet, I’d like to ask something about a snippet that I got. It should supposedly hide woocommerce free shipping option when total (not subtotal) is under the woocommerce minimum amount (excluding the discount applied by the payment gateway then). The thing is that the snippet is not doing what it’s suppose to do, so I’d like to know what could be wrong with it. Thank you

/**
* @snippet Hide free shipping if under minimum amount
*/
add_filter( ‘woocommerce_package_rates’, hide_free_shipping, 10, 2 );
function hide_free_shipping($rates, $package) {

// Get Min Amount from Woo Settings
$free_shipping_settings = get_option( ‘woocommerce_free_shipping_settings’ );
$min_amount = $free_shipping_settings[‘min_amount’];

// Get Cart Total
$current = WC()->cart->cart_contents_total;

// If Total < Min Amount hide free shipping
if ( $current < $min_amount ) {
unset( $rates[‘free_shipping’] );
}
return $rates;
}

Thanks for your reply Caleb.

If somebody already has the snippet adaption to new woocommerce 2.6 and could share, I would appreciate!

Hi Mike!
I’m glad for your reply, but I’m not a coder, so unfortunately I can’t understand what you mean.
I can’t find any plugin that could calculate the discount before the shipping costs calculation, so I think it’s an issue related to woocommerce, isn’t it?
Thanks again!
