exclude a product or category from Free Shipping freeoptions

[gotlogos]

I am wanting to simply be able to flag a category, in my specific case, gift cards, from being included in the cart total when determining if the customer gets free shipping or not.

I offer free shipping when the cart total goes over $57. Problem is a few people have figured out that when they add a gift card to their cart to make the total over 57.00, it triggers the free shipping.

I read a thread trying to glean some info on how to do this but the solutions they seemed to be looking for were much more complicated than what I need and felt there MUST be an easy way to do this. I simply want to eliminate a category from figuring in the total to determine if they get free shipping.

Any help would be appreciated.

You would need to adjust all the references to:
$_SESSION['cart']->show_total()

by the amount of Products that you do not allow to be counted ...

Are all of the Gift Certificates in the same Category and use the same master_categories_id on them?

Thanks Ajeh--yes they are all in same dedicated master category---actually I only use one product and I use attributes and price by attributes...

This takes a little work ...

Let's say we do not want to have products_id 47 and 32 included in the price check when the Free Shipping in the Modules ... Order Totals ... Shipping ot_shipping is set to 50.00 and enabled ...

First, create a new file:
/includes/functions/extra_functions/reduce_free_shipping.php

and add the code:

<?php
// calculate amount not to be used for Products 186 and 10 for free shipping
  function reduce_free_shipping() {
    global $cart;
    $exclude_products = "47, 32";
    $products = $_SESSION['cart']->get_products();
    $chk_price = 0;
    for ($i=0, $n=sizeof($products); $i<$n; $i++) {
      if (in_array((int)$products[$i]['id'], explode(",", $exclude_products))) {
        $chk_price += $products[$i]['final_price'] * $products[$i]['quantity'];
      }
    } // end FOR loop

    return $chk_price;
  }
?>

Next, we have to customize a few files:
/includes/modules/shipping_estimator.php

and use your templates and overrides for:
/includes/modules/your_template_dir/shipping_estimator.php

and change around line 158:

    if ( ($pass == true) && ($_SESSION['cart']->show_total() - reduce_free_shipping() >= MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER)) {

Then we have to adjust the headers for the checkout_shipping, checkout_payment and checkout_confirmation ...

Change the code around line 121:
/includes/modules/pages/checkout_shipping/header_php.php

    if ( ($pass == true) && ($_SESSION['cart']->show_total() - reduce_free_shipping() >= MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER) ) {

Change the code around line 36:
/includes/modules/pages/checkout_payment/header_php.php

if (isset($_SESSION['shipping']['id']) && $_SESSION['shipping']['id'] == 'free_free' && defined('MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER') && $_SESSION['cart']->show_total() - reduce_free_shipping() < MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER) {

Change the code around line 43:
/includes/modules/pages/checkout_confirmation/header_php.php

if (isset($_SESSION['shipping']['id']) && $_SESSION['shipping']['id'] == 'free_free' && defined('MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER') && $_SESSION['cart']->show_total() - reduce_free_shipping() < MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER) {

Then, what I think is the final change around line 34:
/includes/modules/order_total/ot_shipping.php

        if ( ($pass == true) && ( (($order->info['total'] - reduce_free_shipping()) - $order->info['shipping_cost']) >= MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER) ) {

Now, if the Order Total, less the amount of the Products with products_id 47 and 32, is >= 50.00, as set in the Shipping ot_shipping, the shipping will be Free ...

Easy smeazy, eh?

That only took all morning ...

I have never been so humbled in a long long time...I don't even know what to say but thanks...I will be making a donation to the Zen Cart project whether I can get this going or not...having a little trouble after doing all this and double/triple checking. Sent you a PM about it.

But either way many thanks.

Looking at your site it appears that you are using the Free Shipping Options freeoptions shipping module ... this is not being used for the code that I posted ...

This is setup for the Modules ... Order Total ... Shipping ot_shipping ...

Set the Free Orders for over to 57.00 and set the Enable to True ...

Does this fix things?

[gotlogos]

Works famously : ) Thank you...

Is there any way I can still see other shipping modules on this though...now it only shows free shipping but I'd like to be able to let them choose my flat rate which is set up for Priority at 5.00 and also to upgrade to Express if they want that?

Then we have to do it a totally different way ...

Let me give this a little thought ...

[Ajeh]

First, let's undo some code changes ...

Remove the changes from the files ...

Around line 158, remove the change:
/includes/modules/your_template_dir/shipping_estimator.php

Around line 121, remove the change:
/includes/modules/pages/checkout_shipping/header_php.php

Around line 36, remove the change:
/includes/modules/pages/checkout_payment/header_php.php

Around line 43, remove the change:
/includes/modules/pages/checkout_confirmation/header_php.php

Around line 34, remove the change:
/includes/modules/order_total/ot_shipping.php

Now, edit the file:
/includes/modules/shipping/freeoptions.php

and around line 93 change to:

            if (($_SESSION['cart']->show_total() - reduce_free_shipping()) >= MODULE_SHIPPING_FREEOPTIONS_TOTAL_MIN) {

Go to Modules ... Shipping ... and install the Free Shipping Options freeoptions and set the Total >= 57.00 ...

Now, you will see all of your Shipping methods and only see the Free Shipping Options freeoptions when the Order, less anything excluded, is set >= $57.00 ...

Hi there,

I was wondering if there is a way to exclude an entire category from free shipping? I offer free shipping for products totaling over $100, but would like to charge shipping for 1 or 2 categories no matter how much they order. Is that possible?

Thank you,

Tom
