Think of your WooCommerce store like a library. Each book is a product, and each section (fiction, non-fiction, etc.) is a product category. Knowing how to access these categories programmatically allows you to build custom displays and features, just like a librarian uses a catalog to help people find what they need.
Why Would You Need to Get All Product Categories?
There are tons of reasons why you might want to retrieve all your WooCommerce product categories. Here are a few common scenarios:
- Creating a Dynamic Category Menu: Instead Check out this post: Woocommerce How To Remove County Field of manually updating your navigation menu every time you add a new category, you can automatically generate it based on the existing categories. Think of Amazon’s mega-menus, where product categories are dynamically generated.
- Building a Category Filter: Allowing customers to filter products by category on your shop page. This is especially useful for stores with a large product catalog, making it easier for customers to find exactly what they’re looking for.
- Displaying Categories on the Homepage: Showcasing your main product categories on your homepage to guide users and improve navigation. Think of how many e-commerce sites highlight their key categories front and center.
- Creating Category-Specific Landing Pages: Building dedicated landing pages for each category to improve SEO and provide a targeted user experience. For instance, a landing page dedicated to “Running Shoes” with optimized content and relevant products.
- Reporting and Analytics: Analyzing your sales data by category to identify top-performing categories and areas for improvement.

Using `get_terms()` to Retrieve Product Categories
The most common and reliable way to get all product categories in WooCommerce is by using the `get_terms()` function. This function is part of WordPress’s core functionality and is designed to retrieve taxonomy terms. In WooCommerce, product categories are stored as a taxonomy called `product_cat`.
Here’s a simple code snippet you can use:
'product_cat', 'hide_empty' => false, // Set to true to hide categories with no products ) );
if ( ! empty( $product_categories ) && ! is_wp_error( $product_categories ) ){
echo ‘
- ‘;
- ‘ . $category->name . ‘
foreach ( $product_categories as $category ) {
echo ‘
‘;
}
echo ‘
‘;
} else {
echo ‘
No product categories found.
‘;
}
?>
Let’s break down this code:
- `get_terms( array( ‘taxonomy’ => ‘product_cat’, ‘hide_empty’ => false ) )`: This is the core of the code. It calls the `get_terms()` function with an array of arguments.
- `’taxonomy’ => ‘product_cat’` tells the function to retrieve terms from the `product_cat` taxonomy (which is where WooCommerce stores product categories).
- `’hide_empty’ => false` tells the function to include categories even if they don’t have any products assigned to them. If you only want to show categories with products, set this to `true`.
- `if ( ! empty( $product_categories ) && ! is_wp_error( $product_categories ) )`: This checks if the `$product_categories` variable is not empty and that there are no errors. This is important to prevent errors if there are no categories or if something went wrong.
- `foreach ( $product_categories as $category )`: This loop iterates through each product category retrieved.
- `echo ‘
- ‘ . $category->name . ‘
‘`
: This line generates the HTML for each category. - `get_term_link( $category )` retrieves the URL for the category archive page.
- `$category->name` retrieves the name of the category.
- `echo ‘
- ‘;` and `echo ‘
‘;`
: These lines create an unordered list to display the categories. - `echo ‘
No product categories found.
‘;`
: This line is displayed if no product categories are found.
Where to Put This Code?
Where you put this code depends on where you want to display the product categories. Here are a few options:
- In Your Theme’s `functions.php` File: This is a good place for reusable code that you want to use in multiple places. You can create a custom function that retrieves the categories and then call that function in your templates.
- Learn more about How Doi Change From Standard To Classic In Woocommerce In a Template File: If you want to display the categories on a specific page, you can add the code directly to that page’s template file (e.g., `page.php`, `single.php`, or a custom template). Be very careful when editing theme files directly. Always back up your theme first.
- In a Custom Plugin: If you’re building a custom feature for your store, you can create a plugin and add the code there. This is the most organized and maintainable approach for complex functionality.
- Using a Code Snippets Plugin: For simple tasks, you can use a code snippets plugin to add the code without directly modifying your theme files.
Customizing the Output
You can customize the output of the category list in many ways. Here are a few ideas:
- Display Category Images: If you’ve added images to your product categories (using a plugin or theme feature), you can retrieve and display those images.
- Show Category Descriptions: You can display the description you’ve added to each category in the WordPress admin panel.
- Order Categories Alphabetically: You can modify the `get_terms()` arguments to order the categories alphabetically. For example: `’orderby’ => ‘name’, ‘order’ => ‘ASC’`
- Exclude Specific Categories: You can exclude specific categories by adding an `’exclude’` argument to the `get_terms()` array. For example: `’exclude’ => array(1, 5, 10)` to exclude categories with IDs 1, 5, and 10.
Example: Displaying Categories with Images
Let’s say you’re using a plugin that allows you to add images to your WooCommerce product categories. Here’s how you can modify the code to display those images:
'product_cat', 'hide_empty' => false, ) );
if ( ! empty( $product_categories ) && ! is_wp_error( $product_categories ) ){
echo ‘
- ‘;
- ‘;
if ( $image_url ) {
echo ‘
name ) . ‘” />’;
}
echo ‘Learn more about How To Force Display Recipient Address Field In Woocommerce Gifting get_term_link( $category ) . ‘”>’ . $category->name . ‘‘;
echo ‘
foreach ( $product_categories as $category ) {
$thumbnail_id = get_term_meta( $category->term_id, ‘thumbnail_id’, true ); // Assuming your plugin uses ‘thumbnail_id’
$image_url = wp_get_attachment_url( $thumbnail_id );
echo ‘
‘;
}
echo ‘
‘;
} else {
echo ‘
No product categories found.
‘;
}
?>
Important Notes:
- `get_term_meta()`: This function retrieves metadata associated with a term (in this case, a product category). You’ll need to know the name of the metadata key used by your plugin (e.g., `’thumbnail_id’`).
- `wp_get_attachment_url()`: This function retrieves the URL of an attachment (in this case, the category image).
- `esc_url()` and `esc_attr()`: These functions are used to sanitize the URLs and attributes, respectively, to prevent security vulnerabilities. Always sanitize your data!
Conclusion
Getting all your product categories in WooCommerce is a fundamental skill for any developer working with the platform. By using the `get_terms()` function, you can easily retrieve and display your categories in a variety of ways, creating custom navigation menus, category filters, and more. Remember to consider where you’re placing the code and to sanitize your data to ensure a secure and functional website. Happy coding!
