Introduction

WooCommerce, a popular e-commerce plugin for WordPress, provides extensive features for managing online stores. In this tutorial, we’ll explore how to treat cart items separately when their quantity is greater than 1. This can be useful in scenarios where you need to apply specific actions or conditions based on individual quantities in the shopping cart.

Prerequisites

1. WordPress installed with WooCommerce activated.
2. Basic understanding of PHP and WooCommerce.

Steps:

Step 1: Open Your Theme’s Functions.php File

Navigate to your WordPress dashboard, go to “Appearance” > “Theme Editor,” and select your theme’s functions.php file.

Step 2: Add a Custom Function

Insert the following PHP code at the end of your theme’s functions.php file:

/**
 * Treat cart items separately if quantity is more than 1
 */
add_action('woocommerce_before_calculate_totals', 'dcs_custom_quantity_treatment');
function dcs_custom_quantity_treatment($cart) {
    if (is_admin() && !defined('DOING_AJAX')) {
        return;
    }

    // Iterate through each cart item
    foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
        // Check if item quantity is greater than 1
        if ($cart_item['quantity'] > 1) {
            // Add your custom treatment logic here
            // For example, apply a discount or perform a specific action
            // You can access item details using $cart_item['data']
        }
    }
}

This code hooks into the ‘woocommerce_before_calculate_totals’ action, which is triggered before WooCommerce calculates the cart totals. It checks each cart item’s quantity and allows you to apply custom treatment when the quantity is greater than 1.

Step 3: Customize Your Treatment Logic

Inside the loop where the quantity condition is checked, you can add your custom treatment logic. For example, you might want to apply a discount, change the product price, or perform any specific action based on individual cart items.

// Example: Apply a 10% discount for items with quantity greater than 1
$discount_percentage = 10;
$cart_item['data']->set_price($cart_item['data']->get_price() * (1 - ($discount_percentage / 100)));

Step 4: Save Changes and Test

Save the changes to your functions.php file and test the behavior by adding products with different quantities to the cart. Ensure that your custom treatment logic is applied correctly for items with a quantity greater than 1.

Conclusion: Congratulations! You’ve successfully implemented a solution to treat cart items separately in WooCommerce when their quantity exceeds 1. This customization gives you the flexibility to apply specific actions or conditions based on individual items in the shopping cart, enhancing the functionality of your WooCommerce store.

Happy coding !!!! 🙂
