Introduction
When working with an eCommerce platform like Magento 2, customization is often necessary to meet specific business needs. One common customization involves hiding elements on the product page based on certain conditions. For instance, you might want to hide the quantity box for specific products that utilize custom attributes. If you've ever struggled to figure out how to conditionally hide the quantity box in Magento 2, this guide will provide you with a comprehensive solution.
By the end of this post, you will understand how to check custom attributes in Magento 2 and apply conditional logic to your templates. This article will guide you through the details of modifying the addtocart.phtml template to achieve the functionality you desire. Whether you're an experienced developer or relatively new to Magento, this post will provide valuable insights.
Understanding the Use Case
Before diving into the implementation, it's important to clarify the reasoning behind hiding the quantity box. For example, if you sell business cards with various customization options like material type, sides, quantity, and lamination, you might want to present a fixed set of options to the user without allowing them to specify a quantity directly. Instead of displaying a generic quantity box, you'd rely on custom attributes to manage the different variants of the product.
Step-by-Step Implementation
Step 1: Identify the Custom Attribute
First, we need to identify the custom attribute that we will use to determine whether the quantity box should be displayed. For the sake of this example, let's assume we have a custom attribute called quantity_active.
Step 2: Update the addtocart.phtml Template
Navigate to your Magento 2 installation and find the addtocart.phtml template file. This file is usually located in the following directory:
app/design/frontend/[Vendor]/[Theme]/Magento_Catalog/templates/product/view/addtocart.phtml
Open the addtocart.phtml file in a text editor and locate the section where the quantity box is rendered.
Step 3: Fetch the Custom Attribute Value
To conditionally hide the quantity box, we need to fetch the value of the quantity_active attribute for the current product. Add the following PHP code to retrieve the attribute value:
<?php $quantityActive = $_product->getCustomAttribute('quantity_active')->getValue(); ?>
This line of code retrieves the value of the quantity_active custom attribute and stores it in the $quantityActive variable. Ensure that this code is placed at the top of the file or before the quantity box rendering logic.
Step 4: Apply Conditional Logic
With the custom attribute value fetched, we can now apply the conditional logic to hide the quantity box. Use an if statement to check the value of $quantityActive and render the quantity box only if the attribute's value is No:
<?php if ($quantityActive === 'No'): ?>
<!-- Quantity Box HTML Code -->
<!-- Existing code for rendering the quantity box goes here -->
<?php endif; ?>
If the quantity_active attribute is set to Yes, the quantity box will be hidden.
Additional Recommendations
Use a Yes/No Attribute Type
Using a Yes/No attribute type for the quantity_active attribute is a clean and efficient approach. By setting the default value to No, only products explicitly configured to hide the quantity box will do so. This reduces the risk of unexpected behavior for products where the attribute is not set correctly.
Testing
Before deploying these changes to a live environment, always test them on a staging server. Verify that the quantity box appears or disappears as expected for various products.
Conclusion
Customizing Magento 2 to conditionally hide the quantity box based on custom attributes is a practical solution for businesses with unique product configurations. By following the steps outlined in this guide, you can modify the addtocart.phtml template to achieve this functionality smoothly. Whether you're dealing with business cards or any other product type that requires tailored purchasing options, this method provides the flexibility needed to enhance the user experience.
Feel free to adapt the provided code snippets to suit your specific requirements. With a bit of customization, you can unlock a wide range of possibilities to make your Magento store more dynamic and user-friendly.

Can I apply this logic to other elements on the product page?
Yes, the same logic can be extended to hide or show any other elements on the product page based on custom attributes. Simply adjust the conditional checks accordingly.
