exclude products from free shipping

[mikestaps]

The thumb twiddling has begun!

The only thing I could think to do was to put a simple if/else statement around that chunk of code so it wouldn't calculate those items towards free ship if a certain qty of each was in the cart, but that still doesn't solve the 20 + 20 issue...

I thought I had it figured out....

I created functions/extra_functions/reduce_free_shipping.php

<?php
// calculate amount not to be used for Products 144, 443, 148, 473 if all items in cart are from category 93
  function reduce_free_shipping() {
    global $cart;
    $how_many_items = $_SESSION['cart']->count_contents();
	$how_many_oils = $_SESSION['cart']->in_cart_check('master_categories_id', '93');
	if ($how_many_items == $how_many_oils) {  
	$exclude_products = "144, 443, 148, 473";
    $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;
    }
  }
?>

and added to freeoptions.php:

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

Nothing happened!?!?!

Thumb twiddling continues!

So your new function is only saying to do this when the number of Products in the cart is the same quantity as the Products in Category 93:

    if ($how_many_items == $how_many_oils) {

Is that what you really mean?

Or do you mean, always do this and based on whether or not Products in the cart are any of the Products in Category 93, then do the test to reduce the total should any of those Products be in the cart?

[mikestaps]

That is what I mean to do. All of the oils are in cat 93. I don't want the customer to be able to get free shipping on just oils.
I sell the oils as an add item at a low price for the customers convenience, if they order just oil I end up loosing money by the time I pay the shipping.
If the customer orders a bunch of other stuff and then adds one or two of the oils I still want that to count towards free shipping.

Okay so I have Free Shipping Options set with Total >= 350.00 ...

I add to the cart a $300.00 worth of Products NOT is cat 93 ... then another $100.00 worth of Products from cat 93 ... do I get Free Shipping on my $400.00 order?

I add to the cart a $325.00 worth of Products NOT is cat 93 ... then another $100.00 worth of Products from cat 93 ... do I get Free Shipping on my $425.00 order?

I add to the cart a $340.00 worth of Products NOT is cat 93 ... then another $100.00 worth of Products from cat 93 ... do I get Free Shipping on my $440.00 order?

I add to the cart a $340.00 worth of Products NOT is cat 93 ... then another $25.00 worth of Products from cat 93 ... do I get Free Shipping on my $365.00 order?

I add to the cart a $350.00 worth of Products NOT is cat 93 ... then another $100.00 worth of Products from cat 93 ... do I get Free Shipping on my $450.00 order?

[mikestaps]

Yes - free shipping on all examples.
Only when cat 93 makes up 100% of cart is freeoptions to be off.

I see where your going....
I was over complicating this to the "N"th degree!!!
I should be able to just add to the freeoptions.php:

// disable only when entire cart is free shipping
      if (zen_get_shipping_enabled($this->code)) {
          $this->enabled = ((MODULE_SHIPPING_FREEOPTIONS_STATUS == 'True') ? true : false);
       }      
 //check if entire cart is oils
		$how_many_items = $_SESSION['cart']->count_contents();
		$how_many_oils = $_SESSION['cart']->in_cart_check('categories_id', '93');
	
		if ($how_many_items == $how_many_oils) {
			$this->enabled = false;
			}

right?
