I need to create 2000 coupons to sell, but I would like the customers who will use them to always pay for shipping. Currently the threshold for getting free shipping is set above 69€. I tried to use the code below (taken from here: Applied coupons disable Free shipping conditionally in Woocommerce).
It applies to all coupons though, and I'd like to apply it only on coupons with the prefix 'pd'.
add_filter( 'woocommerce_package_rates', 'coupons_removes_free_shipping', 10, 2 );
function coupons_removes_free_shipping( $rates, $package ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return $rates;
$applied_coupons = WC()->cart->get_applied_coupons();
if( sizeof($applied_coupons) > 0 ) {
// Loop through shipping rates
foreach ( $rates as $rate_key => $rate ) {
// Targeting "Free shipping" only
if( 'free_shipping' === $rate->method_id ) {
unset($rates[$rate_key]); // Removing current method
}
}
}
return $rates;
}
