This article, authored by Amandeep Singh, one of our proficient web developers, delves into the customization of a Shopify feature that could be highly beneficial for numerous eCommerce businesses. Amandeep has recently implemented a quantity restriction on product variants within Shopify, which can be achieved without the need for a paid application.
In this article, I will guide you through the process of integrating this functionality into your Shopify store. To begin, I’ll provide a demonstration to set you on the right track:
Each product offers various size options, and the maximum quantity allowed for each variant is clearly outlined in the product description section.
The product features multiple variants, such as size and leg length, with the maximum quantity for each combination specified in the product description.
For this example, I’m utilizing the Shopify Timber theme and the Metafields Editor app, a free tool, to impose limits on each variant.
**Step 1:** Navigate to the product you wish to customize. Access the Metafields Editor app from the product admin dashboard. Click on the Variants tab and add a “metafield” for the variant. Configure the Metafield with the following details:
– Namespace: limit
– Key: max
– Value Type: integer
– Value: Any Numeric Value (e.g., 2)
Ensure you save these details for each variant.
**Step 2:** Proceed to the Theme Editor and open product.liquid. Locate the code block below and replace it with the following:
[… code block with detailed instructions …]
**Step 3:** Add the following JavaScript code to the bottom of product.liquid:
[… JavaScript code snippet …]
**Step 4:** In the cart.liquid template file, define the variable `{% assign processCheckout = true %}` at the beginning of the file.
**Step 5:** Replace the existing code block in cart.liquid with the provided code snippet, which includes a quantity limit for each item.
**Step 6:** Modify the code block at the end of cart.liquid to display a message if the maximum limit is exceeded.
Upon completing these steps, your Cart Limiter should be fully functional. If you encounter any issues, feel free to reach out for assistance. Additionally, you can view the complete code on Github for reference.
