get main product category list woocommerce

Question

I am using woo commerce theme for my site. I am trying to display a list of main product category list. I tried this code. But it returns all the main and sub categories.

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

I need to display just the main product category list. How to do that?

Answer 1

Check the parent of each category, top-level terms will have a parent value of 0:

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

foreach( $product_category as $cat ):
    if( 0 == $cat->parent )
        echo $cat->name;
endforeach;
