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 += ?

What version php?

What version Zen Cart?

You have an add-on ... have you posted on the thread for that contribution for this issue?

[frostyy]

PHP - 4.4.2

Zen - the last version of 1.2

I haven't posted anywhere else, I was thrown with the new forum and wasnt sure where to post it.

Could you look in your Admin ... Tools ... Server Info ... and get the exact version of Zen Cart?

Current version is v1.3.0.2 ...

Sorry about that, it is - Zen Cart 1.2.7
