@coteproducteurs my little solution is in Woocommerce code: https://docs.woocommerce.com/document/hide-other-shipping-methods-when-free-shipping-is-available/
Change: if (‘local_pickup’ === $rate->method_id )
For: if (‘wc_pickup_store’ === $rate->method_id )
function hide_shipping_when_free_is_available( $rates, $package ) {
$new_rates = array();
foreach ( $rates as $rate_id => $rate ) {
// Only modify rates if free_shipping is present.
if ( 'free_shipping' === $rate->method_id ) {
$new_rates[ $rate_id ] = $rate;
break;
}
}
if ( ! empty( $new_rates ) ) {
//Save local pickup if it's present.
foreach ( $rates as $rate_id => $rate ) {
if ('wc_pickup_store' === $rate->method_id ) {
$new_rates[ $rate_id ] = $rate;
break;
}
}
return $new_rates;
}
return $rates;
}
add_filter( 'woocommerce_package_rates', 'hide_shipping_when_free_is_available', 10, 2 );
