Before diving into the methods, it’s important to understand what a WooCommerce category ID represents. Each category in your WooCommerce store has a unique numerical identifier, the ID. This ID is used internally by WordPress and WooCommerce to reference the category within the database. Knowing this ID allows you to directly access and manipulate the category’s information programmatically. You can usually find the category ID in the URL when editing a category in your WordPress admin panel. It’s typically a number following `category=` in the URL.
Methods to Retrieve WooCommerce Categories from ID
Here are three common ways to retrieve WooCommerce category details using their ID:
1. Using `get_term` Function
This is the most straightforward and recommended method. The WordPress function `get_term()` is highly versatile and efficient.
<?php $category_id = 123; // Replace 123 with your desired category ID
$category = get_term( $category_id, ‘product_cat’ );
if ( ! is_wp_error( $category ) ) {
echo ‘Category Name: ‘ . $category->name . ‘
‘;
echo ‘Category Slug: ‘ . $category->slug . ‘
‘;
echo ‘Category Description: ‘ . $category->description . ‘
‘;
// Access other category properties as needed…
} else {
echo ‘Category not found.’;
}
?>
This code snippet first defines the `$category_id`. Then, `get_term()` retrieves the category data. The second argument, `’product_cat’`, specifies that we’re working with WooCommerce product categories. The `if` statement handles potential errors, such as an invalid category ID.

2. Using `get_terms` Function (for Multiple IDs or specific arguments)
The `get_terms()` function offers more flexibility, allowing you to retrieve multiple categories or filter by specific attributes. For instance, if you have an array of category IDs:
<?php $category_ids = array( 123, 456, 789 );
$categories = get_terms( array(
‘taxonomy’ => ‘product_cat’,
‘include’ => $category_ids,
) );
foreach ( $categories as $category ) {
echo ‘Category Name: ‘ . $category->name . ‘
‘;
// Access other category properties as needed…
}
?>
This example uses the `include` parameter to specify the desired category IDs. You can also use other parameters like `hide_empty`, `parent`, `order`, and `orderby` to fine-tune your query. This method is particularly useful when dealing with multiple categories or needing more control over the retrieved data.
3. Using WP_Query (for context-aware retrieval)
If you’re already using a `WP_Query` object, you can leverage it to efficiently retrieve category data within the loop:
123, // Use 'cat' for category ID 'post_type' => 'product' );
$query = new WP_Query( $args );
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
$category_ids = wp_get_post_categories(get_the_ID());
foreach ($category_ids as $cat_id){
$category = get_term( $cat_id, ‘product_cat’);
echo “Post: “.get_the_title().” is Check out this post: How To Change Spacing On Woocommerce in category: “.$category->name.”
“;
}
}
wp_reset_postdata();
} else {
echo ‘No Read more about How To Ship Products Together Woocommerce products found in this category.’;
}
?>
This method utilizes `WP_Query` to get products from a specific category, and then it loops through them to get the category name using `get_term`. Remember to reset the post data using `wp_reset_postdata()` after the loop. This approach is efficient if you need category information within a post loop context.
