    Default Observer for when the orderstatus is changed in the backend of the webshop

    I was wondering is there is an observer for when the status of an order is changed in the back-admin of the webshop?

    I want to execute a customer function the moment the status of an order is changed to 'delivered' within the backend of the webshop.
    To accomplish that I created an class in the directory ./includes/classes/observers and an autoloader.

    The principal of the observer works when using a total different notifier, but I can't find the correct notifier for changing the orderstatus within the backend of the webshop.
    I tried all the notifiers as descibed in the documentation, but none of them seems to do the job..

    Since you're running zc156, yes. The function zen_update_orders_history (present for both the admin and storefront operation) issues the following notification:
    PHP Code:
    $GLOBALS['zco_notifier']->notify('ZEN_UPDATE_ORDERS_HISTORY_STATUS_VALUES', array('orders_id' => $orders_id'new' => $orders_new_status'old' => $orders_current_status)); 
    That function's present in /includes/functions/functions_osh_update.php.

    Default Re: Observer for when the orderstatus is changed in the backend of the webshop

    Thanks for the quick reply, but I'am new to ZenCart development and don't know where to put that code.
    I tried to implement your suggestion as follow.
    But when I change the status of an order within the admin nothing happens.


    ./includes/auto_loaders/config.custom_process_status.php

    PHP Code:
    <?php

    if (!defined('IS_ADMIN_FLAG')) {
        die(
    'Illegal Access');
    }
    $autoLoadConfig[190][] = array('autoType'=>'class',
        
    'loadFile'=>'observers/class.custom_process_status.php');
    $autoLoadConfig[190][] = array('autoType'=>'classInstantiate',
        
    'className'=>'custom_process_status',
        
    'objectName'=>'custom_process_status');
    ./includes/classes/obervers/custom_process_status.php

    PHP Code:
    <?php

    class custom_process_status extends base {
        
        function 
    __construct() {
            
    $this->attach($this, array(''ZEN_UPDATE_ORDERS_HISTORY_STATUS_VALUES' ));
        }

        function update($orderid, $new, $old)
        {
            // Do the magic.....
                    echo ' 
    It works';
                    die();

        }
    }

    Default Re: Observer for when the orderstatus is changed in the backend of the webshop

    Basically for the observer to execute from an admin operation, then something needs to include/require the observer code and then instantiate the observer class... this can be done by loading the catalog side config file from the admin side's same location...

    Note that by the config file being in the catalog side, that it will fire also when/if the notifier is triggered from the catalog side...

    Do I correctly read that to say you HAVE it working with a different Admin-side notifier? Which one? Or only for a Catalog-side notifier? Which one?
    ie: have you put the auto_loaders file on the admin side and got it to load there?
