本文实例讲述了Yii框架上传图片用法。分享给大家供大家参考，具体如下：

Yii 提供了 CUploadedFile 来上传文件，比如图片，或者文档。

官方关于这个类的介绍 :

CUploadedFile represents the information for an uploaded file.
Call getInstance to retrieve the instance of an uploaded file, and then use saveAs to save it on the server. You may also query other information about the file, including name, tempName, type, size and error.
public properties

Property	Type	Description	Defined By
error	integer	Returns an error code describing the status of this file uploading.	CUploadedFile
extensionName	string	the file extension name for name.	CUploadedFile
hasError	boolean	whether there is an error with the uploaded file.	CUploadedFile
name	string	the original name of the file being uploaded	CUploadedFile
size	integer	the actual size of the uploaded file in bytes	CUploadedFile
tempName	string	the path of the uploaded file on the server.	CUploadedFile
