Conditionally adding a cart fee if no coupons are applied to cart

Question

In WooCommerce, I am trying to figured out how to add a "Handling Fee" to every order when no coupons or promo codes are applied to cart.

Here's my "Fee" or "Handling Charge" code:

    add_action( 'woocommerce_cart_calculate_fees','endo_handling_fee' );

function endo_handling_fee() {

global $woocommerce;

     if ( is_admin() && ! defined( 'DOING_AJAX' ) )
          return;

     $fee = 2.00;
     $woocommerce->cart->add_fee( 'Handling', $fee, true, 'standard' );
}

Any ideas?

Thanks

Answer 1

Here I get the array of cart applied coupons and if there is no coupons applied to cart, then a fee is applied to cart.

Here is that code:

add_action( 'woocommerce_cart_calculate_fees','conditional_handling_fee' );
function conditional_handling_fee() {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // Get the applied coupons + the count (in cart)
    $applied_coupons_arr = WC()->cart->get_applied_coupons();
    $applied_coupons_count = count($applied_coupons_arr);

    $fee = 2.00;

    if( 0 == $applied_coupons_count )
        WC()->cart->add_fee( 'Handling - '.$applied_coupons_count, $fee, true, 'standard' );

}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and works.
