Applied coupons disable Free shipping conditionally in Woocommerce

问题


I am trying to get it so that if a customer were to add a coupon code (Any of them) the Free Shipping option would go away and the flat rate fee would be implemented. - You would think this would be an easy thing to implement, there would be 100's of plugins and ways described to do this, but I have not found any. I do not want to pay $89 for the plugin to do this one thing

A side bonus would be if they are using a coupon but are spending over $249 they can still qualify for Free shipping. I read some where how to do this, but it requires me to get the POST ID, which with the latest WooCommerce is not possible like it was before, I do not know the shipping ID so I am at a lost Here is the code

add_filter( 'woocommerce_shipping_packages', function( $packages ) {
$applied_coupons = WC()->session->get( 'applied_coupons', array() );
if ( ! empty( $applied_coupons ) ) {
$free_shipping_id = 'free_shipping:2';
unset($packages[0]['rates'][ $free_shipping_id ]);
}
return $packages;
} );

Thanks

Edited

add_filter( 'woocommerce_package_rates', 'coupons_removes_free_shipping', 
10, 2 );
function coupons_removes_free_shipping( $rates, $package ){
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
    return $rates;

$min_total      = 250; // Minimal subtotal allowing free shipping

// Get needed cart totals
$total_excl_tax = WC()->cart->get_total();
$discount_excl_tax = WC()->cart->get_discount_total();


// Calculating the discounted subtotal including taxes
$discounted_subtotal_incl_taxes = $total_excl_tax - $discount_excl_tax;

$applied_coupons   = WC()->cart->get_applied_coupons();

if( sizeof($applied_coupons) > 0 &&  $discounted_subtotal_incl_taxes < $min_total ) {
    foreach ( $rates as $rate_key => $rate ){
        // Targeting "Free shipping"
        if( 'free_shipping' === $rate->method_id  ){
            unset($rates[$rate_key]);
        }
    }
}
return $rates;

}

The below code will enable "Free shipping" for applied coupons only if cart subtotal reaches a minimal amount (discounted including taxes):

add_filter( 'woocommerce_package_rates', 'coupons_removes_free_shipping', 10, 2 );
function coupons_removes_free_shipping( $rates, $package ){
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return $rates;

    $min_subtotal      = 250; // Minimal subtotal allowing free shipping

    // Get needed cart subtotals
    $subtotal_excl_tax = WC()->cart->get_subtotal();
    $subtotal_incl_tax = $subtotal_excl_tax + WC()->cart->get_subtotal_tax();
    $discount_excl_tax = WC()->cart->get_discount_total();
    $discount_incl_tax = $discount_total + WC()->cart->get_discount_tax();

    // Calculating the discounted subtotal including taxes
    $discounted_subtotal_incl_taxes = $subtotal_incl_tax - $discount_incl_tax;

    $applied_coupons   = WC()->cart->get_applied_coupons();

    if( sizeof($applied_coupons) > 0 && $discounted_subtotal_incl_taxes < $min_subtotal ){
        foreach ( $rates as $rate_key => $rate ){
            // Targeting "Free shipping"
            if( 'free_shipping' === $rate->method_id  ){
                unset($rates[$rate_key]);
            }
        }
    }
    return $rates;
}

Code goes in function.php file of your active child theme (or active theme). Tested and work.


Original answer:

The bellow code will remove "Free shipping" shipping methods when any coupon is applied without any settings need. There is some mistakes in your actual code. Try the following:

add_filter( 'woocommerce_package_rates', 'coupons_removes_free_shipping', 10, 2 );
function coupons_removes_free_shipping( $rates, $package ){
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return $rates;

    $applied_coupons = WC()->cart->get_applied_coupons();

    if( sizeof($applied_coupons) > 0 ){
        // Loop through shipping rates
        foreach ( $rates as $rate_key => $rate ){
            // Targeting "Free shipping" only
            if( 'free_shipping' === $rate->method_id  ){
                unset($rates[$rate_key]); // Removing current method
            }
        }
    }
    return $rates;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

By default WooCommerce will still allow a free shipping method to be selected if the coupon code is filled in and active in the shopping cart. The following code can be added to your child’s functions.php page to hook in and hide any free shipping option if a coupon code is used.

add_filter( 'woocommerce_shipping_packages', function( $packages ) {
$applied_coupons = WC()->session->get( 'applied_coupons', array() );
if ( ! empty( $applied_coupons ) ) {
$free_shipping_id = 'free_shipping:2';
unset($packages[0]['rates'][ $free_shipping_id ]);
}
return $packages;
} );

Simply change the $free_shipping_id in the above code to the ID of your free shipping option. You may find your ID by going to WooCommerce > Settings > Shipping Options and then click on your Free Shipping option. The post ID will be in the URL of the page that displays the Free Shipping details/settings.

i.e www.yourdomain.com/wp-admin/post.php?post=40107&action=edit

Where 40107 is the shipping ID in this example. Your shipping ID will be different.
