Message:

I have a mystery with the categories from WooCommerce.
For different products I have multiple categories.
For example the product Nike Air Red
I connect this product with two categories Brands->Nike and Shoes->Red
Brands and Shoes are main categories and Nike and Red are subcategories.

On the product page I have the following code

$terms = wp_get_post_terms( $post->ID, 'product_cat' );

foreach ($terms as $term) {

    echo $term->name;

}

The output is NikeRed

Is there a way to get one category?
Nike or Red?

I tried also

get_ancestors(get_queried_object_id(), 'product_cat')

But this array is empty

My Answer:
Nike and Colors-Red._When I try to get the categories for this product using the `get_the_terms()` function, I get an array with both categories._But I only want to display one category for each product._How can I achieve this?_

You can achieve this by using the `wp_get_post_terms()` function instead of `get_the_terms()`. This function allows you to specify which taxonomy you want to retrieve terms from and limit the number of terms returned.

Here's an example of how you can use `wp_get_post_terms()` to get only one category term for a WooCommerce product:

php
$product_id = get_the_ID(); // Get the current product ID

$categories = wp_get_post_terms( $product_id, 'product_cat', array( 'fields' => 'names' ) );

if ( ! empty( $categories ) ) {
$category = $categories[0]; // Get the first category term
echo $category; // Display the category term
}


In this example, we are using the `wp_get_post_terms()` function to retrieve the product categories for the current product ID. We are specifying the taxonomy as `product_cat` (the taxonomy used for product categories in WooCommerce) and setting the `fields` parameter to `names` to only retrieve the category names.

We then check if the `$categories` array is not empty and get the first category term from the array. Finally, we display the category term using `echo`.

This way, you will only display one category term for each product, even if the product is assigned to multiple categories.
