Header And Session Error After Adding Free Gift Mod

[enchantedone]

hi everyone sorry to post again. we are working on getting a free gift mod in out store. we figured out how to do it, this is what we did

we made this file and named it config.freeProduct.php and uploaded to includes/autoloaders

<?php 

$autoLoadConfig[90][] = array('autoType'=>'class',
               'loadFile'=>'observers/class.freeProduct.php');
$autoLoadConfig[90][] = array('autoType'=>'classInstantiate',
               'className'=>'freeProduct',
               'objectName'=>'freeProduct');
?>

and made this file named class.freeProduct.php and uploaded to includes/classes/observers

<?php
/**
 * Observer class used to add a free product to the cart if the user spends more than $x
 *
 */
class freeProduct extends base {
 /**
  * The threshold amount the customer needs to spend.
  * 
  * Note this is defined in the shops base currency, and so works with multi currency shops
  *
  * @var decimal
  */
 var $freeAmount = 50;
 /**
  * The id of the free product.
  * 
  * Note. This must be a true free product. e.g. price = 0 Also make sure that if you don't want the customer
  * to be charged shipping on this, that you have it set correctly.
  *
  * @var integer
  */
 var $freeProductID = 57;
 /**
  * constructor method
  * 
  * Attaches our class to the $_SESSION['cart'] class and watches for 2 notifier events.
  */
 function freeProduct() {
  $_SESSION['cart']->attach($this, array('NOTIFIER_CART_ADD_CART_END', 'NOTIFIER_CART_REMOVE_END'));
 }
 /**
  * Update Method
  * 
  * Called by observed class when any of our notifiable events occur
  *
  * @param object $class
  * @param string $eventID
  */
 function update(&$class, $eventID) {
  if ($_SESSION['cart']->show_total() >= $this->freeAmount && !$_SESSION['cart']->in_cart($this->freeProductID) ) {
   $_SESSION['cart']->add_cart($this->freeProductID);
  }
  if ($_SESSION['cart']->show_total() < $this->freeAmount && $_SESSION['cart']->in_cart($this->freeProductID) ) {
   $_SESSION['cart']->remove($this->freeProductID);
  }
  if ($_SESSION['cart']->in_cart($this->freeProductID)) {
   $_SESSION['cart']->contents[$this->freeProductID]['qty'] = 1;
  }
 }
}
?>

once these were uploaded we got these errors

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/cara1977/public_html/includes/auto_loaders/config.freeProduct.php:8) in /home/cara1977/public_html/includes/functions/sessions.php on line 100

also the font sizes on our site changed.

i searched and found alot of header error but none related to this mod.

we are using 1.3.0.2

im just not sure what to do, if anyone has any insight i would greatly appreciate it.

thanks so much

I seem to be getting the same error (but did not add the free gift mod).

Warning: Variable passed to each() is not an array or object in /home/www/staging/includes/classes/db/mysql/query_factory.php on line 112

Any one have any input?

The other messages I found on the forums about this had remarks about removing unseen spaces at the end of the .php file in the errors above. I checked those files for excess spaces and it has not corrected the situation.

I found my own fix. :)

I had run out of disk space!! The last thing I had done on the site was to upload a bunch of sample .mp3 files and it pushed my over my server limit, thus causing an error about the session cache, i.e. not able to write to the cache directory, yielding the ugly error! Woo-hoo!

Good-bye OsCommerce
Hello Zen-Cart

As a recent convert to Zen-Cart, it just keeps getting better and better. This is the single best addition to the Zen-Cart that I've seen so far. Thank you very much for the work that went into developing it. It works like a charm.
