我建议您首先查看“wpsc\\u purchase\\u log\\u update”操作，该操作在wpsc includes/purchase log中触发。班php并传递wpsc\\u purchase\\u log对象。测试$previous_status 该对象的成员，以及新的状态值（可能在数据成员中为$data[\'statusno\']) == WPSC\\u购买日志：：已调度作业。

类似这样（未经测试）：

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 ...
    }
}
