在这篇文章之后，我终于设法通过扩展Magento_Adminhtml_Controller_Action并在它之前执行一些操作来捕获一个事件。但现在我正在尝试改进它，以便我可以捕获在管理面板上触发的另一个事件，并从那里将一个数组通过request变量传递给前端的另一个事件。我有这些 SO 问题/答案，在这里和这里，但我无法实现我所需要的。我已经测试了observer code使用die()以确保执行线程进入正确的调用并且没问题。我正在使用 AlanStorm 的 CommerceBug，以防它可以用来解决这个问题。

这是我的 Observer.php 代码。

<?php
class Dts_Videotestimonials_Model_Observer {

    public function hookToAdminhtmlControllerActionPreDispatch($observer)
    {
        if($observer->getEvent()->getControllerAction()->getFullActionName() == 'videotestimonials_adminhtml_videotestimonialsbackend_post')
        {
            // dispatching our own event before action upload video is run and sending parameters we need
            Mage::dispatchEvent("upload_video_before", array('request' => $observer->getControllerAction()->getRequest()));
        }
    }

    public function hookToUploadVideoBefore($observer)
    {
        //Hooking to our own event
        $request = $observer->getEvent()->getRequest()->getParams();
        // do something with product

        $user = Mage::getSingleton('admin/session');
        $userName = $user->getUser()->getFirstname();
        $userEmail = $user->getUser()->getEmail();

        $request['product_id'] = "16"; #$_product->getId(),
        $request['author_email'] = $userEmail;
        $request['author_name'] = $userName;
        $request['video_link'] = "http://www.youtube.com/watch?v=y435u6kfExA&feature=youtube_gdata_player";
        $request['video_type']  = "link";
        $request['title'] = "AT&T Phone Nokia 2610";
        $request['comment'] = "this is a comment";
        Mage::dispatchEvent("vidtest_youtube_post", $request);
    }
}

这是完整的 config.xml

这是正在发生的事情。您的管理控制器配置错误。将控制器包含在管理部分的正确方法是这样（您需要更改模块名称以匹配您的）：

<?xml version="1.0" ?>

<config>
    <modules>
        <Video_Awesome>
            <version>0.0.1</version>
        </Video_Awesome>
    </modules>
    <global>
        <models>
            <Video_Awesome>
                <class>Video_Awesome_Model</class>
                <!-- No resource model used currently -->
            </Video_Awesome>
        </models>
        <events>
            <controller_action_predispatch>
                <observers>
                    <controller_action_before>
                        <type>singleton</type>
                        <class>Video_Awesome/Observer</class>
                        <method>controllerActionPredispatch</method>
                    </controller_action_before>
                </observers>
            </controller_action_predispatch>
            <upload_video_before>
                <observers>
                    <Video_Awesome>
                        <type>singleton</type>
                        <class>Video_Awesome/Observer</class>
                        <method>uploadVideoBefore</method>
                    </Video_Awesome>
                </observers>
            </upload_video_before>
        </events>
    </global>

    <admin>
        <routers>
            <adminhtml>
            <!-- we are not creating our own router, but tapping into the adminhtml router -->
                <args>
                    <modules>
                        <!-- Your module name, and then
                        the path to the controller (minus
                        the controllers folder name). So,
                        in this instance, I put the router
                        in a "Adminhtml" folder inside of
                        the controllers folder, like thus:
        Video/Awesome/controllers/Adminhtml/videotestimonialsController.php -->
                        <Video_Awesome before="Mage_Adminhtml">Video_Awesome_Adminhtml</Video_Awesome>
                    </modules>
                </args>
            </adminhtml>
        </routers>
    </admin>
</config>

getEvent然后，在您的路由器中（在获取控制器操作之前您不需要调用）：

public function controllerActionPredispatch ($observer)
{
    if($observer->getControllerAction()->getFullActionName() == 'adminhtml_videotestimonials_post') {
        // dispatching our own event before action upload video is run and sending parameters we need
    Mage::dispatchEvent("upload_video_before", array('request' => $observer->getControllerAction()->getRequest()));
    }
}

最后，听起来好像您没有针对 Magento 开发的调试设置。我强烈推荐一个。我使用 PHPStorm（我在公司中没有任何股份 - 这不是广告 :)，而且效果非常好。在那里设置一个断点，看看变量是什么。

我还建议使用adminhtml_controller_action_predispatch_start, 而不是 global controller_action_predispatch，因为它只会在后端触发（性能差异非常非常小）。

另外，作为一个小旁注，我在您的 中看到，您config.xml在那里指定了菜单项/acl。你可能不知道，但那是不推荐使用的功能，那些项目应该放在它adminhtml.xml.
