operand types

[frostyy]

Hi,

I had someone send me this error -

Fatal error: Unsupported operand types in
/home/martianc/public_html/shop/includes/classes/shopping_cart.php on
line 763

They are using a safari browser, it doesn't seem to happen in other browsers. I am using version 1.2, it has been heavily customizable so upgrading isn't really an easy option. Can anyone shed any light here? Thanks a million.

Sorry, the line above shows:

$discount_type_id = '';

Can you post the file shopping_cart.php?
Thanks

Actually, I was looking at the wrong shopping cart page. The correct one has the Dual Pricing mod making line 763:

$attributes_price += $attribute_price;

changing this to


$attributes_price == $attribute_price;


seems to fix the problem but I don't know if it will mess with anything else?

Just as a test, make a file: test.php

<?php
  $calculation = 27;
  $calculation2 = 27;

  $calculation == $calculation;
  $calculation2 += $calculation2;

  echo $calculation . ' vs ' . $calculation2;

?>

The results will be: 27 vs 54

There is a difference ...

I see, so do you have any idea why this wouldn't work with += ?
