后端代码:

<?php/** * 附件上传管理 * */class PQAdmin_AttachmentController extends PQAdmin_BaseController {function actionNew(){$allowext = $this->_request_->request('allowext',null);$callback = $this->_request_->request('callback',null);$label = $this->_request_->request('label',null);$this->_view['allowext'] = $allowext;$this->_view['callback'] = $callback;$this->_view['label'] = $label;$this->_viewname = 'show';}function actionSave(){$allowext = $this->_request_->request('allowext',App::ini('_uploader/allowext'));$callback = $this->_request_->request('callback',null);$label = $this->_request_->request('label',null);$maxSize = App::ini('_uploader/maxsize');$uploadDir = App::ini('_uploader/dir');$uploadBaseurl = App::ini('_uploader/baseurl');$prefix = date('Y/m/d',CURRENT_TIMESTAMP);do {if (is_dir($uploadDir) && is_writable($uploadDir)){$fileDir = $uploadDir . '/' . $prefix;if (is_dir($fileDir)){if (!is_writable($fileDir)){js_alert("上传文件目录[{$fileDir}]不可写,请检查权限设置",'',$this->_request_->referer());}    }else {  if (!FileSystemHelper::mkdirs($fileDir)){  js_alert("上传文件目录[{$fileDir}]创建失败,请检查权限设置",'',$this->_request_->referer());  }  }break;}js_alert("上传文件目录[{$uploadDir}]不可写,请检查权限设置",'',$this->_request_->referer());} while(false);$uploader = new FileUploaderHelper();$files = $uploader->getFiles();$fileInfo = array();// 这个地方每次只会上传一个文件foreach ($files as $file) {  if (!$file->check($allowext, $maxSize)) {// 上传的文件类型不符或者超过了大小限制。js_alert(App::ini('_uploader/errorstext'),'',$this->_request_->referer());return false;}// 生成唯一的文件名（重复的可能性极小）    $id = md5(time() . $file->getFilename() . $file->getSize() . $file->getTmpName());  $filename = $id . '.' . strtolower($file->getExt());  $file->move($fileDir . '/' . $filename);    $fileInfo['name'] = "/{$prefix}/{$filename}";  $fileInfo['size'] = $file->getSize();  $fileInfo['mime'] = $file->getMimeType();  break;}$this->_view['allowext'] = $allowext;$this->_view['callback'] = $callback;$this->_view['label'] = $label;$this->_view['callbackObject'] = json_encode($fileInfo);$this->_viewname = 'show';}    /**     * 执行控制器动作之前调用     */    protected function _beforeExecute($actionName)    {    // 检查用户是否为登录状态//    if (!PQAdmin_UserModel::isLogin()){//redirect(url('application','logout'));//}    }}

要使用的地方只需如此调用即可:

<script>function uploadImg(fileInfo){console.log(fileInfo);//.uploadImage.value}</script><div>    <iframe src="<?php echo url('attachment','new',null,array('allowext'=>'jpg','callback'=>'window.parent.uploadImg','label'=>h('上传图片:')));?>" style="border:0px;height:30px;width: 100%" frameborder="0" cellspacing="0" allowTransparency="true" scrolling="no" resizable="no"></iframe></div>

上传成功会自动执行回调函数:

输出结果:

{ name="/2011/05/22/03c4524eccb3b33226a83e7817883727.jpg", size=39583, mime="image/jpeg"}
