The quantity added to your cart has been adjusted because of a restriction on max

[tlwolter]

I am having a problem in my shopping cart. I have products that have quantity limits set. I can add a product to the cart with out issue. I start to have problems when I try to change the quantities in the shopping cart. I have a max quantity set to 10 items. If I only have a quantity of 1 in the cart and want to change it to 2, I have no problem. However, if I have 1 and want to change to 10, I get the message that I have exceeded my limit. It acts like it is adding the previous value and the changed value to determine if I am exceeding my quantity limit. You can view my site at: www.crappietomtackle.com/shop

If you edit the file:
/includes/classes/shopping_cart.php

and change the code around line 1557 to read:

          // adjust quantity if needed
          if ($new_qty > $add_max) {
            if (($new_qty + $cart_qty > $add_max) and $add_max != 0) {
              $adjust_max= 'true';
              $new_qty = $add_max - $cart_qty;
            }
          }

does this fix the problem?

That did indeed fix the problem. Thanks for the quick assistance.

Thank you for confirming that this was able to fix the Maximum Value issue that you were having with the update quantity ...

What version is this one?

[Ajeh]

I believe this is a problem in v1.3.9e and v1.3.9f ...

seeing this error in 1.3.9e:

shopping cart page:

The quantity added to your cart has been adjusted because of a restriction on maximum you are allowed. See this item:

Error triggered by deleting items with checkbox(es) and update cart button on cart page

error on all remaining products that are in cart, that are:

Product Qty Minimum: 1
Product Qty Maximum: 1
Product Qty Units: 1
Product Qty Min/Unit Mix: Yes
Products Quantity: 1

*not seeing this error on products that are in cart, that are: :

Product Qty Maximum: *more than 1
Products Quantity: *more than 1

--------

ALSO: Using the trash can icon to delete (not the checkbox/update cart) does not trigger this error.

[Ajeh]

This is fixed in v1.3.9f ...

//die('I see Update Cart: ' . $_POST['products_id'][$i] . ' add qty: ' . $add_max . ' - cart qty: ' . $cart_qty . ' - newqty: ' . $new_qty);
        if (($add_max == 1 and $cart_qty == 1)) {
          // do not add
          $adjust_max= 'true';
        } else {
          // adjust quantity if needed
          if ($new_qty > $add_max) {
            if (($new_qty + $cart_qty > $add_max) and $add_max != 0) {
              $adjust_max= 'true';
              $new_qty = $add_max - $cart_qty;
            }
          }
          $attributes = ($_POST['id'][$_POST['products_id'][$i]]) ? $_POST['id'][$_POST['products_id'][$i]] : '';
          $this->add_cart($_POST['products_id'][$i], $new_qty, $attributes, false);
        }
        if ($adjust_max == 'true') {

Hi Linda!

I tried that fix before posting in includes/classes/shopping_cart.php but it had no effect.

[dharma]

I just tried using the includes/classes/shopping_cart.php from 1.3.8f still no effect (the only change from 1.3.9e to f is the breadcrumb fix)

I then dialed back to 1.3.9d's includes/classes/shopping_cart.php and do not see the errors.

Must have something to do with these doohickies (added lines from d to e/f):

Line 1535-1537:

      if ($_POST['cart_quantity'][$i] == '') {
        $_POST['cart_quantity'][$i] = 0;
      } 

and Line 1546:

        $cart_qty = $this->in_cart_mixed($_POST['products_id'][$i]); 

Should I just take those bad boys out?
