如何在Magento管理面板中向订单视图添加新按钮？

Question

如何在"后退"和"编辑"附近添加自定义按钮以订购视图页面？

Answer 1

而不是核心黑客或重写,只需使用观察者将按钮添加到订单:

<adminhtml>
    <events>
        <adminhtml_widget_container_html_before>
            <observers>
                <your_module>
                    <class>your_module/observer</class>
                    <type>singleton</type>
                    <method>adminhtmlWidgetContainerHtmlBefore</method>
                </your_module>
            </observers>
        </adminhtml_widget_container_html_before>
    </events>
</adminhtml>

然后只需检查观察者是否类型与订单视图匹配:

public function adminhtmlWidgetContainerHtmlBefore($event)
{
    $block = $event->getBlock();

    if ($block instanceof Mage_Adminhtml_Block_Sales_Order_View) {
        $message = Mage::helper('your_module')->__('Are you sure you want to do this?');
        $block->addButton('do_something_crazy', array(
            'label'     => Mage::helper('your_module')->__('Export Order'),
            'onclick'   => "confirmSetLocation('{$message}', '{$block->getUrl('*/yourmodule/crazy')}')",
            'class'     => 'go'
        ));
    }
}

块的"getUrl"函数将自动将当前订单ID附加到控制器调用.

config.xml文件:

<global>
    <blocks>
         <adminhtml>
            <rewrite>
                <sales_order_view>Namespace_Module_Block_Adminhtml_Sales_Order_View</sales_order_view>
            </rewrite>
        </adminhtml>
    </blocks>
 </global>

命名空间/模块/块/ Adminhtml /销售/订单/ View.php:

class Namespace_Module_Block_Adminhtml_Sales_Order_View extends Mage_Adminhtml_Block_Sales_Order_View {
    public function  __construct() {

        parent::__construct();

        $this->_addButton('button_id', array(
            'label'     => Mage::helper('xxx')->__('Some action'),
            'onclick'   => 'jsfunction(this.id)',
            'class'     => 'go'
        ), 0, 100, 'header', 'header');
    }
}
