Really I've tried several different ways just to get an indication that zc actually runs it.

I have had absolutely no luck so far.

I couldn't get it to work where I NEED it to work, so I backed up to test with a dummy variable put in the session cookie attached to the session'cart' class. That didn't work either!

The set up is:
in autoloaders/overrides/config.vendorProducts.php
PHP Code:
<?php

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

And in classes/observers/vendorProducts.php
PHP Code:
<?php
 
class vendorProducts extends base {
     
     function 
vendorProducts() {
$_SESSION['cart']->attach($this, array('NOTIFIER_CART_SHOW_TOTAL_END'));

    }
    function 
update(&$class$eventID) {
    
        
$_SESSION['vendorProducts'] = 'true';
    
    } 
// end function update
  
}
?>
So what am I missing here?

TIA,
