Checking products in cart based on category name woocommerce?

Question

I\'m trying to trigger an echo statement if a certain category of product is in my cart, here\'s my code:

Answer 1

@Guillaume and others who helped- thanks for posting this for it was helpful to me. Once I started testing I realized that the code didn't work for all of my products. Some products in my case have categories with sub-categories and that was preventing the code from picking up the relevant categories on all the products. I altered your code slightly to create an array and it seems to be working well:

function check_product_in_cart() {
    //Check to see if user has product in cart
    global $woocommerce;

    // start of the loop that fetches the cart items

    foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
        $_product = $values['data'];
        $terms = get_the_terms( $_product->id, 'product_cat' );

        // second level loop search, in case some items have several categories
        // this is where I started editing Guillaume's code

        $cat_ids = array();

        foreach ($terms as $term) {
            $cat_ids[] = $term->term_id;
        }

        if(in_array(434, (array)$cat_ids) || in_array(435, (array)$cat_ids)) {

          //category is in cart!
           $product_in_cart = true;
        }
    }

    return $product_in_cart;
}
