Remove a country from allowed countries if specific product category is in WooCommerce cart

[SOLVED] How would I adjust this to change country available in the Checkout page by Product Category and not specific Products?

limit shippable country by product category

I'm attempting this:

/* HIDE U.S. as a country destination if category is "Canada Only" */

add_filter( 'woocommerce_countries', 'products_disable_country', 10, 1 );
function products_disable_country( $countries ) {

    if( is_cart() || is_checkout() ) {
    
        $product_cat = array(195);
    
        foreach( WC()->cart->get_cart() as $item ){
            if( in_array( $item['product_cat'], $product_cat ) ){
                unset($countries["US"]);
                return $countries;
            }
        }
    }
    
    return $countries;

}

But no dice yet...

Used this answer code as a base:
Remove a country from allowed countries when specific products are in WooCommerce cart

Edit (Added some screenshots):

Product is Lemon Tarts, categorized as "Canada Only":.

Category ID for that is 195:

Checkout still shows US as an option in the shipping section:

Thanks Loic! Your final update worked perfectly, see below: enter image description here

You're a star!

Solution

  • Update (replaced initial "woocommerce_countries" hook)

    To check if a product (or an item) is assigned to a product category term, you should use has_term() conditional WordPress function like:

    add_filter( 'woocommerce_countries_allowed_countries', 'allowed_countries_for_product_category', 10, 1 );
function allowed_countries_for_product_category( $countries ) {
    // Only on cart and checkout pages
    if( is_cart() || ( is_checkout() && !is_wc_endpoint_url() ) ) {
        $country_code   = 'US'; // Define the targeted country code to disable
        $targeted_terms = array(195); // Define your category(ies) (terms IDs, slugs or names)
        $category_found = false; // Initializing

        // Loop through cart items
        foreach ( WC()->cart->get_cart() as $item ) {
            // Check if one of the targeted categories is assigned
            if( has_term($targeted_terms, 'product_cat', $item['product_id']) ) {
                $category_found = true; // Tag as found
                break; // Stop the loop
            }
        }

        // Remove the targeted country if any targeted category is found
        if ( $category_found && isset($countries[$country_code]) ){
            unset($countries[$country_code]);
        }
    }
    return $countries;
}

    Code goes in functions.php file of your child theme (or in a plugin). Tested and work.

    For "Ship to", targeting shipping countries only, use additionally:

    add_filter( 'woocommerce_countries_shipping_countries', 'allowed_countries_for_product_category', 10, 1 );
