Question

我需要在收到processing状态后自动在订单上创建发票。在我的扩展中应该观察哪个事件来实现这个目标？

我正在尝试，但这段代码不起作用，它可以是什么？

etc / modules中的

.xml

<?xml version="1.0"?>
<config>
<modules>
    <Atwix_Orderhook>
        <active>true</active>
        <codePool>community</codePool>
    </Atwix_Orderhook>
</modules>
</config>

app / code /...

中的

config.xml

<?xml version="1.0"?>
<config>
<modules>
    <Atwix_Orderhook>
        <version>1.0</version>
    </Atwix_Orderhook>
</modules>
<global>
    <models>            
        <orderhook>
            <class>Atwix_Orderhook_Model</class>
        </orderhook>
    </models>
    <events>
        <sales_order_save_after>
            <observers>
                <auto_invoice_order>
                    <type>singleton</type>
                    <class>Atwix_Orderhook_Model_Observer</class>
                    <method>implementOrderStatus</method>
                </auto_invoice_order>
            </observers>
        </sales_order_save_after>
    </events>

</global>
</config>

Oberver.php在app / code /...

<?php
class Atwix_Orderhook_Model_Observer 
{
public function implementOrderStatus($event)
{
    $order = $event->getOrder();

    if ($order == 'processing') {
        if ($order->canInvoice())
            $this->_processOrderStatus($order);
    }
    return $this;
}
                        private function _processOrderStatus($order)
                        {
                            $invoice = $order->prepareInvoice();

                            $invoice->register();
                            Mage::getModel('core/resource_transaction')
                               ->addObject($invoice)
                               ->addObject($invoice->getOrder())
                               ->save();

                            $invoice->sendEmail(false, '');
                            return true;
                        }
}

Answer 1

您可以观察Intent detailIntent = new Intent(this, ContinentsListActivity.class); startActivity(detailIntent);，然后使用以下内容检查您要定位的订单状态：

sales_order_save_after
