Conditionally hide shipping methods in WooCommerce - php

Question

I am trying to hide a shipping method on the checkout page of WooCommerce when shipping country selected is United States - 'US' and cart_total is more than 100. But the script is still hiding both the Normal Shipping and Express shipping, when it should only hide the normal shipping(flat_rate:4). Any help will be greatly appreciated!
function nd_hide_shipping_when_free_is_available( $rates ) {
$shipping_counrtry = WC()->customer->get_shipping_country();
$total = WC()->cart->get_displayed_subtotal();
if ($shipping_country == "US" && $total >= 100){
unset($rates['flat_rate:4']);
return $rates;
}else{
$free = array();
foreach ( $rates as $rate_id => $rate ) {
if ( 'free_shipping' === $rate->method_id ) {
$free[ $rate_id ] = $rate;
break;
}
}
return ! empty( $free ) ? $free : $rates;
}
}
add_filter( 'woocommerce_package_rates', 'nd_hide_shipping_when_free_is_available', 100 );

Answer 1

You can try the following, that will hide 'flat_rate:4' shipping method rate id for US and when cart subtotal reaches 100 or more, otherwise when free shipping is available, it will hide other shipping methods:
add_filter( 'woocommerce_package_rates', 'shipping_based_on_country_subtotal_and_free_available', 100, 2 );
function shipping_based_on_country_subtotal_and_free_available( $rates, $package ) {
$country = WC()->customer->get_shipping_country();
$subtotal = WC()->cart->subtotal; // subtotal incl taxes
$condition = $country == "US" && $subtotal >= 100; // <== HERE Set your condition (country and minimal subtotal amount)
$free = array(); // Initializing
// Loop through shipping rates for current shipping package
foreach ( $rates as $rate_key => $rate ) {
if ( $condition ){
$targeted_rate_id = 'flat_rate:4';
if( $targeted_rate_id === $rate_key ) {
unset($rates[$targeted_rate_id]);
}
}
elseif ( 'free_shipping' === $rate->method_id ) {
$free[$rate_key] = $rate;
}
}
return ! empty( $free ) && ! $condition ? $free : $rates;
}
Code goes in functions.php file of the active child theme (or active theme). Tested and works.
Important: Once code is saved, empty the cart to refresh shipping rates...
