Hide some shipping rates based on taxonomy terms in WooCommerce 4.8+ - php

Question

I use this to unset shipping for product with specific tag:
function specific_products_shipping_methods( $rates, $package ){
// etiquette cocolis
$terms = array( 'cocolis' );
$taxonomy = 'product_tag';
foreach( $package['contents'] as $cart_item ) {
if ( has_term( $terms, $taxonomy, $cart_item['product_id'] ) )
{
unset( $rates['oik_weight_zone_shipping_49'] );
unset( $rates['chrono10'] );
unset( $rates['chrono13'] );
add_filter('woocommerce_shipping_chosen_method', 'reset_default_shipping_method', 10, 2);
}
}
return $rates;
}
add_filter( 'woocommerce_package_rates', 'specific_products_shipping_methods', 10, 2 );
function reset_default_shipping_method( $method, $available_methods ) {
$default_method = 'per_product';
if( array_key_exists($method, $available_methods ) )
return $default_method;
else
return $method;
}
This works fine until update woo 4.8.0
Any idea what’s wrong ?
Thx,

There are some mistakes in your code, try the following revisited and optimized code instead:
add_filter( 'woocommerce_package_rates', 'specific_products_shipping_methods', 10, 2 );
function specific_products_shipping_methods( $rates, $package ){
$terms = array('cocolis'); // Array of term slugs, names or ids
$taxonomy = 'product_tag'; // WooCommerce product tag taxonomy
$rate_keys = array('oik_weight_zone_shipping_49', 'chrono10', 'chrono13'); // Shipping rates to be hidden
$has_unset = false; // Initializing
// Loop through cart items for the current shipping package
foreach( $package['contents'] as $cart_item ) {
// Targeting specific product tags
if ( has_term( $terms, $taxonomy, $cart_item['product_id'] ) ) {
// Loop through shipping rates to be removed (hidden)
foreach( $rate_keys as $rate_key ) {
if (isset($rates[$rate_key]) ) {
unset($rates[$rate_key]);
$has_unset = true; // Flag as unset to enable the filter below
}
}
}
}
if ( $has_unset ) {
add_filter('woocommerce_shipping_chosen_method', 'reset_default_shipping_method', 10, 3 );
}
return $rates;
}
function reset_default_shipping_method( $default, $rates, $chosen_method ) {
$targeted_method = 'per_product'; // The shipping method rate to set as chosen one
if( isset($rates[$targeted_method]) ) {
$default = $targeted_method;
}
return $default;
}
Code goes in functions.php file of the active child theme (or active theme). Tested and works in WooCommerce 4.8+.
Don't forget to empty your cart to refresh WooCommerce shipping caches
Note: For WooCommerce categories, define the $taxonomy variable to product_cat instead.
