Free Shipping - some items - some zones - need upgrades

[djdavedawson]

The ultimate goal is to have just a few products that include Ground shipping. If a customer selects an item that is "free ship", they also have a choice to pay for faster shipping.

If you add weight to all Products ... and mark those for Free Shipping to the US as Always Free Shipping ...

You can make the following customizations ...

Make a Zone Definition defined for the US Only ...

Install the Free Shipping Options freeoptions instead of the FREE SHIPPING! freeshipper ... and set the Total >= 0 and set the Zone to the new Zone Definition for the US Only ...

Edit the code for:
/includes/modules/shipping/freeoptions.php

to include the code in RED:

      // disable only when entire cart is free shipping
      if (zen_get_shipping_enabled($this->code)) {
          $this->enabled = ((MODULE_SHIPPING_FREEOPTIONS_STATUS == 'True') ? true : false);
      }

// bof: Always Free Shipping
      if (!IS_ADMIN_FLAG) {
        global $cart;
echo 'Always Free: ' . $_SESSION['cart']->in_cart_check('product_is_always_free_shipping','1') . ' Count: ' .  $_SESSION['cart']->count_contents();
        if ($_SESSION['cart']->in_cart_check('product_is_always_free_shipping','1') == $_SESSION['cart']->count_contents()) {
          $this->enabled = true;
        }
      }
// eof: Always Free Shipping

      if ( ($this->enabled == true) && ((int)MODULE_SHIPPING_FREEOPTIONS_ZONE > 0) ) {

Edit the code for the UPS shipping module with the code in RED:

    // disable only when entire cart is free shipping
//    if (zen_get_shipping_enabled($this->code)) {
      $this->enabled = ((MODULE_SHIPPING_UPS_STATUS == 'True') ? true : false);
//    }

Edit the code for the shipping class with the code in RED:

  function calculate_boxes_weight_and_tare() {
    global $total_weight, $shipping_weight, $shipping_quoted, $shipping_num_boxes;

// bof: add back Free Shipping
    global $cart;
    $total_weight += $_SESSION['cart']->free_shipping_weight;
//
    if (is_array($this->modules)) {

Now the Free Shipping Options freeoptions will only show for the US when the whole order is Always Free Shipping and the UPS will always show with the proper weight ...

Thank you Oba-san. Let me try this out.

Ok, I put this up on the testing server and it works well.

I did have to change this

if ($_SESSION['cart']->in_cart_check('product_is_always_free_shipping','1') == $_SESSION['cart']->count_contents()) {
          $this->enabled = true;
        } 

to this

if ($_SESSION['cart']->in_cart_check('product_is_always_free_shipping','1') == $_SESSION['cart']->count_contents()) {
          $this->enabled = true;
        } else {$this->enabled = false;} 

So the problem then became how do we handle a mixed cart. With the above solution, A mixed cart would force the customer to pay shipping on the items that were free ship.

I came up with a way to handle a mixed cart, Although my method for recalculating the ground shipping "$mycost" was feeble at best, it's was only off by a dollar or so. I'm hoping there is a more accurate way to do it.

Here is what I did:

Around line 196, i changed this:

$methods[] = array('id' => $type,        
                           'title' => $this->types[$type],
                           'cost' => ($cost * $shipping_num_boxes ) + (MODULE_SHIPPING_UPS_HANDLING_METHOD == 'Box' ? MODULE_SHIPPING_UPS_HANDLING * $shipping_num_boxes : MODULE_SHIPPING_UPS_HANDLING) ); 

to this:

    if ($type=='GND' && $_SESSION['cart']->free_shipping_weight !=0 ) {
        
        if ($_SESSION['cart']->in_cart_check('product_is_always_free_shipping','1') == $_SESSION['cart']->count_contents()) {
        
            } else {
            
            $mycost = $cost * (1-($_SESSION['cart']->free_shipping_weight / ($_SESSION['cart']->free_shipping_weight + $ups_shipping_weight)));
        
        $methods[] = array('id' => $type,        
                           'title' => $this->types[$type] . " (Free Shipping + " . (($ups_shipping_weight * $shipping_num_boxes) - $_SESSION['cart']->free_shipping_weight) ." lbs.)",
                           'cost' => ($mycost * $shipping_num_boxes) + (MODULE_SHIPPING_UPS_HANDLING_METHOD == 'Box' ? MODULE_SHIPPING_UPS_HANDLING * $shipping_num_boxes : MODULE_SHIPPING_UPS_HANDLING) );
        }
        
        } else {
            
        $methods[] = array('id' => $type,        
                           'title' => $this->types[$type],
                           'cost' => ($cost * $shipping_num_boxes ) + (MODULE_SHIPPING_UPS_HANDLING_METHOD == 'Box' ? MODULE_SHIPPING_UPS_HANDLING * $shipping_num_boxes : MODULE_SHIPPING_UPS_HANDLING) );
        } 

What do you think ?

Thanks

Are you saying ...

On a cart that is Always Free Shipping ...

the US only gets:
Always Free Shipping

International gets:
UPS for weight of the Product


On a cart that is mixed Normal products and Always Free Shipping ...

the US only gets:
UPS for the weight of ONLY the Products not marked Always Free Shipping

International gets:
UPS for weight of ALL the Products

[djdavedawson]

Yes, and at the same time, any cart with free ship items, mixed or not will have the ability to upgrade their shipping from Ground at the UPS weight of all the items.

[Ajeh]

Right now, the way the custom code is working is if the cart is Always Free Shipping products only, the US gets:
Free Shipping Options
UPS - for ALL Products with weight

So if you have a Product with the weight of 1.5lbs *and* marked as Always Free Shipping, the US gets the:
Free Shipping Options
UPS - for 1.5 lb quote

Non-US gets:
UPS - for 1.5 lb quote


If you have a Mixed cart where 1 Product is weight of 1.5lbs *and* marked as Always Free Shipping and another Product is weight 2lbs and NOT Always Free Shipping the US gets the:
UPS - for 3.5lb quotes

Non-US gets:
UPS - for 3.5lb quotes

What are you wanting that is different?

Note: If you're using anything prior to 1.3.9a you will need to correct the class shopping_cart.php as follows around 654:

// shipping adjustments
if (($product->fields['product_is_always_free_shipping'] == 1) or ($product->fields['products_virtual'] == 1) or (preg_match('^GIFT', addslashes($product->fields['products_model'])))) {
$this->free_shipping_item += $qty;
$this->free_shipping_price += zen_add_tax($products_price, $products_tax) * $qty;
//$this->free_shipping_weight += ($qty * $products_weight);
$this->free_shipping_weight += ($qty * $product->fields['products_weight']);
}
