Plugin for changing shipping class doesn’t work

    Hello,

    I wrote this piece of code that is supposed to change cart’s shipping class to more expensive one when there are two or more shippable items in the cart.

    <?php
/*
Plugin Name: Change Shipping Class
Description: Modifies the shipping class of products in the cart based on certain conditions.
Version: 1.0
Author: XXX
*/

// Hook into the WooCommerce cart
add_action('woocommerce_before_calculate_totals', 'set_shipping_class_for_first_product');

function set_shipping_class_for_first_product($cart) {
    // Check if the cart is empty
    if ($cart->is_empty()) return;

    // Initialize a variable to track if there's more than one shippable product
    $shippable_products_count = 0;

    // Loop through each cart item
    foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
        // Check if the product can be shipped (you may adjust this condition as per your requirement)
        if ($cart_item['data']->needs_shipping()) {
            $shippable_products_count += $cart_item['quantity'];
        }
        // If this is the first shippable product encountered
        if ($shippable_products_count >= 2) {
            // Set the shipping class to 25 for the first shippable product
            $cart_item['data']->set_shipping_class_id(25);
        }
    }
}

?>

    And I’m testing it thoroughly and it works. But then people order my items and even though they order two items – they pay the lower amount for shipping. Like this script doesn’t work for other people.

    I’ve asked a friend and he said that he sees higher price. I’ve tested in 2 phones and one PC and it also works.

    What can those people do differently that it doesn’t work for them as supposed to?

    I would suggested to use this given below of code. It will work as you desire. 

    add_action('woocommerce_before_calculate_totals', 'set_shipping_class_for_first_product');

function set_shipping_class_for_first_product($cart) {
    // Check if the cart is empty
    if ($cart->is_empty()) return;

    // Initialize a flag to track if the shipping class has been set for the first shippable product
    $shipping_class_set = false;

    // Loop through each cart item
    foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
        // Check if the product can be shipped (you may adjust this condition as per your requirement)
        if ($cart_item['data']->needs_shipping()) {
            // If the shipping class has not been set yet, set it for this product
            if (!$shipping_class_set) {
                $cart_item['data']->set_shipping_class_id(25);
                $shipping_class_set = true; // Set the flag to true to prevent setting the shipping class for subsequent shippable products
                break; // Exit the loop since we have set the shipping class for the first shippable product
            }
        }
    }
}

    Sorry, but this code doesn’t make sense. What’s the point of

    $shipping_class_set

    ? It’s being set to true and then it leave the loop. So it’s pointless.

    Looks like you copy pasted it from ChatGPT.
