已关注 this post我终于成功地通过扩展 Magento_Adminhtml_Controller_Action 来捕获事件并在其之前执行一些操作。但现在我正在尝试改进它，以便我可以捕获管理面板上触发的另一个事件，并从那里通过 request 变量将数组传递到前端的另一个事件。我有这些问题/答案，here和 here但我无法实现我所需要的。我已经使用 die() 测试了观察者代码，以确保执行线程进入正确的调用并且一切正常。我正在使用 AlanStorm 的 CommerceBug，以防它可以用来阐明这个问题。
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);
}
}

最佳答案
这就是正在发生的事情。您的管理 Controller 配置错误。将 Controller 包含在管理部分的正确方法是这样的(您需要更改模块名称以匹配您的名称):
<?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>
然后，在您的路由器中(在获取 Controller 操作之前不需要调用 getEvent):
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，听起来您似乎没有为 Magento 开发进行调试设置。我强烈推荐一款。我使用 PHPStorm(我在该公司没有任何股份 - 这不是广告:)，它的效果非常棒。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，而不是全局controller_action_predispatch，因为它只会在后端触发(非常非常小的性能差异)。
另外，作为一个小旁注，我在您的 config.xml 中看到您在那里指定了菜单项/acl。您可能不知道，但这是已弃用的功能，这些项目应该放在 adminhtml.xml 中。
