I display an information about the needed amount for free shipping.
Like:
Add 10$ more to get free shipping
That all works fine and is based on a fixed amount for the free shipping. My problem is now, that it will also show even if a coupon sets free shipping. Is there any way to check if the order already uses any free shipping method?
I found something here: https://stackoverflow.com/a/32932933/1788961
global $woocommerce;
$shipping_methods = $woocommerce->shipping->load_shipping_methods();
if($shipping_methods['free_shipping']->enabled == "yes")
But it doesn't help.
I also found an interesting snippet here: https://www.businessbloomer.com/woocommerce-hide-shipping-options-free-shipping-available/
$all_free_rates = array();
foreach ( $rates as $rate_id => $rate ) {
if ( 'free_shipping' === $rate->method_id ) {
$all_free_rates[ $rate_id ] = $rate;
break;
}
}
if ( empty( $all_free_rates )) {
return $rates;
} else {
return $all_free_rates;
}
}
