magento 自定义模块使用uploader上传文件

1、在edit/form.php中添加代码：addField('images', 'note', array(        'label'     => Mage::helper('review')->__('Review Image'),        //'required'  => true,        'name'      => 'images',        'text'      => $this->getLayout()->createBlock('xreview/adminhtml_review_image_upload')->_toHtml()，       ));?>2、新建block：silk/xreview/adminhtml/review/image/upload.phpsetTemplate('review/image/upload.phtml');    }    protected function _prepareLayout() {                //加载Uploader插件的js        $this->getLayout()->getBlock('head')->addJs('lib/flex.js');        $this->getLayout()->getBlock('head')->addJs('mage/adminhtml/flexuploader.js');        $this->getLayout()->getBlock('head')->addJs('lib/FABridge.js');        // 添加Mage_Adminhtml_Block_Media_Uploader子块Block        $this->setChild('uploader', $this->getLayout()->createBlock('adminhtml/media_uploader'));        $this->getChild('uploader')->getConfig()            // 文件上传处理action            ->setUrl(Mage::getModel('adminhtml/url')->addSessionParam()->getUrl('xreview/adminhtml_xreview/upload'))            ->setFileField('review_image')            ->setFilters(array(                'images' => array(                    'label' => Mage::helper('adminhtml')->__('Images (.gif, .jpg, .png)'),                    'files' => array('*.gif', '*.jpg','*.jpeg', '*.png')                )            ));        return parent::_prepareLayout();    }}?>3、上一步，声明了blcok对应的phtml,所以新建design/adminhtml/default/default/template/review/image/upload.phtml：        getChildHtml('uploader')?>以上步骤完成以后，就可以看见与产品edit页面image中的2个按钮了4、新建controller:silk/xreview/controllers/adminhtml/xreviewController.phpsetAllowedExtensions(array('jpg','jpeg','gif','png'));            $uploader->setAllowRenameFiles(true);            $uploader->setFilesDispersion(true);            $result = $uploader->save($this->getBaseTmpMediaPath());            Mage::dispatchEvent('catalog_product_gallery_upload_image_after', array(                'result' => $result,                'action' => $this            ));            $result['tmp_name'] = str_replace(DS, "/", $result['tmp_name']);            $result['path'] = str_replace(DS, "/", $result['path']);            $result['url'] =$this->getTmpMediaUrl($result['file']);            $result['file'] = $result['file'];            $result['cookie'] = array(                'name'     => session_name(),                'value'    => $this->_getSession()->getSessionId(),                'lifetime' => $this->_getSession()->getCookieLifetime(),                'path'     => $this->_getSession()->getCookiePath(),                'domain'   => $this->_getSession()->getCookieDomain()            );        } catch (Exception $e) {            $result = array(                'error' => $e->getMessage(),                'errorcode' => $e->getCode());        }        //Mage::log($result,null,'cookie.log');        $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));    }    private function getBaseTmpMediaPath() {        return Mage::getBaseDir('media') . DS . 'review';    }    private function getTmpMediaUrl($file) {        $file = str_replace(DS, '/', $file);        if (substr($file, 0, 1) == '/') {            $file = substr($file, 1);        }        return  Mage::getBaseUrl('media') . 'review/'. $file;    }}?>5、如何处理action的json数据，在upload.phtml中，加入下面的js:  //处理action中的json数据  var uploader = getChild('uploader')->getJsObjectName(); ?>;  uploader.onFilesComplete = function(files) {    var i = 0;    files.each(function(file) {        if(document.getElementById('upload_image_'+i)){            document.getElementById('upload_image_'+i).remove();        }        var str = file.response;        var json = eval('('+str+')');        //图片以隐藏域的方式提交                                            var input = document.createElement('input');        input.setAttribute('type', 'hidden');        input.setAttribute('value', json.file);        input.setAttribute('id', 'upload_image_'+i);        input.setAttribute('name', 'images[]');        document.getElementById('add_review_form').appendChild(input);        i++;    }); }
