Custom Quantity Management in WooCommerce Checkout: A Step-by-Step Guide

When running an online store using WooCommerce, managing product quantities efficiently is crucial, especially when different products can only be sold in specific increments. For example, your store may sell boxes of candy, each containing 12 pieces. If a customer wants to buy multiple boxes, they should be able to input quantities like 12, 24, or even 36. However, you might encounter an issue where the cart displays the initial quantity instead of the intended total quantity. Let's address this common problem and walk through the solution step by step.

The Problem: Quantity Discrepancy at Checkout

In WooCommerce, users setting custom quantities based on product categories might face an issue with the checkout page not reflecting the correct quantities. For example, if a customer adds two boxes of candy (where each box contains 12 pieces), the total should display as 24. However, it only shows 12, leading to confusion and potential loss of sales.

To resolve this issue, we will leverage WooCommerce hooks to ensure that the quantity displayed at checkout mirrors what the customer selected on the shop page.

Solution: Using WooCommerce Hooks

Step 1: Setting Custom Quantity Input Based on Product Category

First, we need to adjust the quantity input field for specific product categories directly on the product page. Here's how to implement custom quantity functionality based on the product category using the woocommerce_quantity_input_args filter:

This code snippet does three main tasks:

Sets the default quantity (input_value) to 12.

Restricts the minimum quantity (min_value) to 12.

Increases the quantity by 12 with each click of the input arrows (step).

Step 2: Ensuring Correct Quantity Display at Checkout

Next, we need to ensure that the quantity displayed in the WooCommerce checkout process corresponds to the quantity the customer selected. To achieve this, we will utilize the woocommerce_checkout_cart_item_quantity filter. Add the following code to your theme's functions.php file:

Explanation of the Code:

This code modifies the quantity displayed for items in the cart that belong to the specified product category (in this case, category "12").

It fetches the product ID from the cart, checks if it belongs to the category, and then formats the quantity correctly.

Conclusion

By implementing the above steps, you can successfully manage product quantities based on their categories on your WooCommerce store. This setup ensures that customers see accurate quantities throughout their shopping experience, boosting satisfaction and potentially increasing sales.

Whether you're running a candy store or any other niche, applying custom quantity arguments to your WooCommerce checkout page provides clarity for your customers and a better shopping experience overall.
