Send email on Job Dispatched from WP e-commerce [closed]

Question

I’d suggest you start by looking at action ‘wpsc_purchase_log_update’, which is triggered in wpsc-includes/purchase-log.class.php and passes the wpsc_purchase_log object. Test the $previous_status member of that object, and the new status value (might be in data member as $data['statusno']) == WPSC_Purchase_Log::JOB_DISPATCHED.

Something like this (untested):

add_action('wpsc_purchase_log_update', 'wpse_73707_wpscPurchaseLogUpdate');

/**
* trigger event or option to the "Job Dispatched" status change
* @param WPSC_Purchase_Log $purchaseLog
*/
function wpse_73707_wpscPurchaseLogUpdate($purchaseLog) {
    if ($purchaseLog->previous_status && $purchaseLog->data['statusno'] == WPSC_Purchase_Log::JOB_DISPATCHED) {
        // send your email ...
    }
}
