Add body class to category with all its subcategories | Woocommerce

I want to add class to the body tag when viewing a category and all its subcategories, the code bellow work but it just add the class to the category in question but not all its subcategories:

add_filter( 'body_class','custom_body_class' );
function custom_body_class( $classes ) {

    if ( is_product_category( 802 ) ) {
        $classes[] = 'class1';
    } else if ( is_product_category( array( 'femme', 'homme', 'enfant' ) ) ) {
        $classes[] = 'class2';
    }

    return $classes;

}

I tried to replace is_product_category with in_category or is_product_tag but It does not work either.

Any help would be appreciated.

You need instead to use the related WordPress conditional function has_term() with the 'product_cat' taxonomy argument to target product categories this way:

add_filter( 'body_class','custom_body_class' );
function custom_body_class( $classes ) {

    if ( has_term( 802, 'product_cat' ) ) { // assuming that 802 is the id of a product category.
        $classes[] = 'class1';
    } else if ( has_term( array( 'femme', 'homme', 'enfant' ), 'product_cat' ) ) {
        $classes[] = 'class2';
    }

    return $classes;

}

Update 2 (based on your comment):

When archive category (or subcategory) pages are empty, is possible to use get_queried_object() function to get the current term object and adapt the conditions in your function to handle those cases.

Here is that code:

add_filter( 'body_class','custom_body_class' );
function custom_body_class( $classes ) {

    // Only on product category (or subcategory) archives pages     
    if(is_product_category()):

    // Set HERE your Main category ID (the parent ID of subcategories IDs)
    $main_cat = 802;

    // Set HERE your subcategories slugs
    $sub_cats_arr = array( 'femme', 'homme', 'enfant' );

    // Getting the current term (object) of category or subcategory archives page 
    $term = get_queried_object();

    // All the needed data from current term (object)
    $term_id = $term->term_id; // term ID
    $term_slug = $term->slug; // term slug
    $term_name = $term->name; // term name
    $term_taxonomy = $term->taxonomy; // Always 'product_cat' for woocommerce product categories
    $term_parent_id = $term->parent; // the parent term_id

    // FOR YOUR MAIN CATEGORY ID '802' (Handle empty archive page case too)
    if ( has_term( $main_cat, $term_taxonomy ) || $term_id == $main_cat )
        $classes[] = 'class1';

    // FOR YOUR MAIN 3 SUBCATEGORIES SLUGS (Handle empty archive page case too)
    if ( has_term( $sub_cats_arr, $term_taxonomy ) || in_array($term_slug, $sub_cats_arr) )
            $classes[] = 'class2';

    endif;

    return $classes;

}

This way you should avoid the case when viewing category or subcategory wich contain no product that doesn't add your body custom class…
