How to Hide Out of Stock Products on Specific Category Archives in WooCommerce

Running an online store using WooCommerce allows you to manage products efficiently. However, one common issue that many store owners face is dealing with out-of-stock products. Especially when filtering products by category, you may want to hide out-of-stock items to enhance the shopping experience. In this guide, we will walk you through how to accomplish this in a clear and straightforward manner.

The Problem: Out of Stock Products Cluttering Your Store

When customers browse through your product categories, the presence of out-of-stock items can lead to frustration and confusion. Showing these products can mislead customers and give a poor impression of your store. Hence, hiding out-of-stock products from specific category archives is a smart strategy to improve customer satisfaction and streamline navigation.

The Traditional Approach: What Doesn't Work

You might start by trying to hook into WordPress queries using the pre_get_posts function. For instance, you might have attempted to write a code snippet like this:

However, you found that this method did not yield the desired results because the query's post type might not have been set correctly.

You might have even tried using a global query object before the loop, as shown here:

Unfortunately, this approach did not filter the products as needed, leading to continued display of out-of-stock items.

The Solution: Utilizing WooCommerce Filters

To efficiently hide out-of-stock products specifically on certain category archives, you'll want to use a WooCommerce filter instead. Here’s how to implement that:

Step-by-Step Implementation

Hook into the WooCommerce Product Query
Instead of using the generic WordPress post query, utilize the woocommerce_product_query hook. This approach is designed to work directly with WooCommerce's product queries.

Add the Code
Insert the following code snippet into your theme's functions.php file or in a custom plugin:

Explanation of the Code

Hooking into WooCommerce: The add_action function hooks our custom function filter_out_of_stock_prod into WooCommerce's product query process.

Modifying the Meta Query: Within our function, we retrieve the existing meta_query, add a condition that checks for the _stock_status key, and filters it to show only products that are 'in stock'.

Finalizing the Query: We then use $q->set to update the query with our new meta_query, which effectively hides the out-of-stock products from the specified category archives.

Conclusion

By following the steps outlined above, you can efficiently filter out-of-stock products from select category pages in your WooCommerce store. Not only does this create a cleaner shopping experience for your visitors, but it also helps convey a more professional image for your brand. Implement this solution today, and watch as your customer satisfaction rates improve!
