  • Hi I already sent you an e-mail, but I figured that this might be faster.

    I wrote this function that generates a subtotal of all the prices of the products within a certain category in the cart:

    function cat_cart_sum() {
            if ( ! is_page( 'winkelmand' ) ) {
            return;
        }
        $cat_count = 0; 
        // Iterating through each cart item
        foreach(WC()->cart->get_cart() as $cart_item)  
            if( has_term( 'Geen actie artikelen', 'product_cat', $cart_item['product_id'])) {
                $regularprice = $cart_item['data']->get_price();
                $price = $regularprice * $cart_item['quantity'];
                $cat_count += $price;
            }
        if ($cat_count >= 40 && $cat_count <= 100) {
                                   wc_add_notice('U krijgt bij het afhalen €10 gratis vuurwerk!', 'notice');
                                   } elseif ($cat_count > 100 && $cat_count <= 200) {
                wc_add_notice('U krijgt bij het afhalen €25 gratis vuurwerk!', 'notice');
            } elseif ($cat_count > 200 && $cat_count <= 300) {
                wc_add_notice('U krijgt bij het afhalen €50 gratis vuurwerk!', 'notice');
            } elseif ($cat_count > 300 && $cat_count <= 400) {
                wc_add_notice('U krijgt bij het afhalen €75 gratis vuurwerk!', 'notice');
            } elseif ($cat_count >= 400) {
                wc_add_notice('U krijgt bij het afhalen €100 gratis vuurwerk!', 'notice');
            }
        return $cat_count;
    }

    What I’m looking for is a way that the $cat_count can be echoed onto the invoice. I was thinking of adding a hidden field to the order_meta or something like that, because calling the function inside of the invoice body.php doesn’t work at all.

    Kind regards,
