Filtering Products by Custom Fields in WooCommerce: A Step-by-Step Guide

Are you looking to enhance your WooCommerce store's functionality by filtering products based on custom fields? This guide will address how to achieve this and display products filtered by the custom field you've created for delivery times. Specifically, we’ll use the meta key custom_text_field_delivery which includes values like 24h, 5days, and 7days.

The Problem

You might have noticed that although you can create custom fields in WooCommerce, utilizing them for product filtering isn’t as straightforward as setting them up. For instance, you may have attempted to filter your products by using a URL like localhost/shop/?custom_text_field_delivery=24h, but found that it didn’t work. Instead of creating separate pages for each delivery option, let’s dive into how to make this filtering work dynamically!

The Solution

To enable product filtering based on your custom field, you can use a filter hook within WordPress. Below is a step-by-step explanation of the process:

Step 1: Access Your Theme's Functions File

You will need to add some code to your theme. Specifically, use the functions.php file of your active child theme or your active theme. This file controls various functions and settings of your WooCommerce store.

Step 2: Use the Filter Hook

Add the following PHP code to the functions.php file:

Code Breakdown:

Hooking into WooCommerce: The add_filter function attaches your custom function (filter_products_with_custom_field) to the WooCommerce product query. This way, when a product query is made, your function modifies the meta query.

Defining the Meta Key: The variable $meta_key stores the name of your custom field (custom_text_field_delivery).

Checking Conditions: The conditional statement checks if it's not the admin area, and whether the custom field value is set and not empty. This is important as we only want to filter products when the appropriate parameter is present in the URL.

Building the Meta Query: If the conditions are met, a new array is added to $meta_query that specifies how to filter the products by the custom field.

Step 3: Test Your Filter

Now that you’ve added the code to your functions.php file, you should be able to filter products using the URL:

Upon hitting this URL, the products with a delivery time of 24h will be displayed.

Conclusion

Implementing product filtering based on custom fields in WooCommerce can significantly enhance user experience by allowing easy access to products that meet specific criteria. With just a few lines of code added to your theme’s functions.php, you can efficiently display products based on the delivery times you've set.

Give it a try, and adjust as necessary to match your store's unique setup. Happy selling!
