本文实例讲述了yii实现使用CUploadedFile上传文件的方法。分享给大家供大家参考,具体如下:
一、前端代码
Html代码:
<form action="<?php echo $this->createUrl('/upload/default/upload/');?>" method="post" enctype="multipart/form-data"> <input type="file" name="file"/> <input type="hidden" name="dir" value="<?php echo Yii::app()->controller->currentDir?>"/> <input type="submit" value="Upload Image"/> </form>
二、后端代码
Php代码:
public function actionUpload() { $this->currentDir = isset($_REQUEST['dir']) ? $_REQUEST['dir'] : ''; $image = CUploadedFile::getInstanceByName('file'); $name = $this->uploadPath.'/'.$this->currentDir.'/'.$image->name; $image->saveAs($name); $this->redirect(array('index','dir'=>$this->currentDir)); }
