Magento订单状态更改事件

Question

我想通过Web服务更改远程库存,我知道通过事件观察器方法可以解决我的代码,但我不知道哪个事件对完成我的任务很有用,比如on_order_complete,是否有更新的事件列表或更多文档？

如果要在订单状态更改为任何状态或状态时调度事件,则需要插入自己的事件侦听器.这并不像听起来那么困难.

只需覆盖这样的_setStatus功能Mage_Sales_Model_Order......

/**
 * Order model
 *
 * @category    WMG
 * @package     WMG_Sales
 * @author      Lee Bolding <lee.bolding@wmg.com>
 *
 *  Supported events:
 *  sales_order_status_before
 *  sales_order_status_after
 *
 * NOTE: Unfortunately, we can't override setState() as the protected _setState()
 * function is used by the registerCancellation() and _checkState() functions
 *  
 */
class WMG_Sales_Model_Order extends Mage_Sales_Model_Order
{
    /**
     * Order state protected setter.
     * By default allows to set any state. Can also update status to default or specified value
     * ?omplete and closed states are encapsulated intentionally, see the _checkState()
     *
     * @param string $state
     * @param string|bool $status

     */
    protected function _setState($state, $status = false, $comment = '', $isCustomerNotified = null, $shouldProtectState = false)
    {
        // dispatch an event before we attempt to do anything
        Mage::dispatchEvent('sales_order_status_before', array('order' => $this, 'state' => $state, 'status' => $status, 'comment' => $comment, 'isCustomerNotified' => $isCustomerNotified, 'shouldProtectState' => $shouldProtectState));

        // attempt to set the specified state
        if ($shouldProtectState) {
            if ($this->isStateProtected($state)) {
                Mage::throwException(Mage::helper('sales')->__('The Order State "%s" must not be set manually.', $state));
            }
        }
        $this->setData('state', $state);

        // add status history
        if ($status) {
            if ($status === true) {
                $status = $this->getConfig()->getStateDefaultStatus($state);
            }
            $this->setStatus($status);
            $history = $this->addStatusHistoryComment($comment, false); // no sense to set $status again
            $history->setIsCustomerNotified($isCustomerNotified); // for backwards compatibility
        }

        // dispatch an event after status has changed
        Mage::dispatchEvent('sales_order_status_after', array('order' => $this, 'state' => $state, 'status' => $status, 'comment' => $comment, 'isCustomerNotified' => $isCustomerNotified, 'shouldProtectState' => $shouldProtectState));

        return $this;
    }
}

您现在可以为新创建的事件sales_order_status_before和sales_order_status_after事件订阅观察者
