向 Magento 核心模块添加额外控制器的最佳实践是什么

Question

我想将名为 SkuController 的附加控制器添加到 CatalogSearch Core 模块。 执行此操作的最佳实践是什么？

谢谢。

Answer 1

所有额外的功能都应该由模块来实现。我建议用新控制器制作一个新模块。

Answer 2

无论您做什么，都不要修改核心，而是创建自定义模块，并确保始终尽可能调用父函数。

使用 ModuleCreater 来简化此任务：

看看 Ivan 的视频教程，忽略 php 单元测试部分，但他解释了全部内容，尤其是在视频中的一半。

控制器类可能如下所示：

class Mycompany_myMod_Adminhtml_myModController extends Mage_Adminhtml_Controller_action
{

    protected function _initAction() {
        $this->loadLayout()
            ->_setActiveMenu('custompromos/items')
            ->_addBreadcrumb(Mage::helper('adminhtml')->__('Items Manager'), Mage::helper('adminhtml')->__('Item Manager'));

        return $this;
    }   

    public function indexAction() {
        $this->_initAction()
            ->renderLayout();
    }

    public function editAction() {
        $id     = $this->getRequest()->getParam('id');
        //Some code here
    }

    public function newAction() {
        $this->_forward('edit');
    }

    public function saveAction() {
        if ($data = $this->getRequest()->getPost()) {
               //Some code here             
        }

    }

    public function deleteAction() {
        if( $this->getRequest()->getParam('id') > 0 ) {
            try {
                //Some code here
            } catch (Exception $e) {
                Mage::getSingleton('adminhtml/session')->addError($e->getMessage());
                $this->_redirect('*/*/edit', array('id' => $this->getRequest()->getParam('id')));
            }
        }
        $this->_redirect('*/*/');
    }

    public function massDeleteAction() {
        //Some code here
        $this->_redirect('*/*/index');
    }

    public function massStatusAction()
    {
        //Some code here
        $this->_redirect('*/*/index');
    }

    public function exportCsvAction()
    {
        $fileName   = 'somedata.csv';
        $content    = $this->getLayout()->createBlock('mymodule/adminhtml_mymodule_grid')
            ->getCsv();

        $this->_sendUploadResponse($fileName, $content);
    }

    public function exportXmlAction()
    {
        $fileName   = 'somedata.xml';
        $content    = $this->getLayout()->createBlock('mymodule/adminhtml_mymodule_grid')
            ->getXml();

        $this->_sendUploadResponse($fileName, $content);
    }

    protected function _sendUploadResponse($fileName, $content, $contentType='application/octet-stream')
    {
        $response = $this->getResponse();
        $response->setHeader('HTTP/1.1 200 OK','');
        $response->setHeader('Pragma', 'public', true);
        $response->setHeader('Cache-Control', 'must-revalidate, post-check=0, pre-check=0', true);
        $response->setHeader('Content-Disposition', 'attachment; filename='.$fileName);
        $response->setHeader('Last-Modified', date('r'));
        $response->setHeader('Accept-Ranges', 'bytes');
        $response->setHeader('Content-Length', strlen($content));
        $response->setHeader('Content-type', $contentType);
        $response->setBody($content);
        $response->sendResponse();
        die;
    }
}
