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


Code:
<?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

Code:
<?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
