谁有yii上传文件实现代码

Answer 1

<?php

class upload
{
var $upload_name; //上传文件名
var $upload_tmp_name; //上传临时文件名
var $upload_final_name; //上传文件的最终文件名
var $upload_target_dir; //文件被上传到的目标目录
var $upload_target_path; //文件被上传到的最终路径
var $upload_filetype ; //上传文件类型
var $allow_uploadedfile_type; //允许的上传文件类型
var $upload_file_size; //上传文件的大小
var $allow_uploaded_maxsize=5000; //允许上传文件的最大值
var $image_w=900; //要显示图片的宽
var $image_h=350; //要显示图片的高

function __construct()
{
$this->upload_name = $_FILES["file"]["name"]; //取得上传文件名
$this->upload_filetype = $_FILES["file"]["type"];
$this->upload_final_name = date("Y-m-d H:i:s").$this->upload_name;
$this->upload_tmp_name = $_FILES["file"]["tmp_name"];
$this->allow_uploadedfile_type = array("image/gif","image/jpeg");
$this->upload_file_size = $_FILES["file"]["size"];
$this->upload_target_dir="./upload";
}

function upload_file()
{
if(in_array($this->upload_filetype,$this->allow_uploadedfile_type))
{
if($this->upload_file_size < $this->allow_uploaded_maxsize)
{
if(!is_dir($this->upload_target_dir))
{
mkdir($this->upload_target_dir);
}
$this->upload_target_path = $this->upload_target_dir."/".$this->upload_final_name;
if(!move_uploaded_file($this->upload_tmp_name,$this->upload_target_path))
echo "<font color=red>文件上传失败！</font>";
}
else
{
echo("<font color=red>文件太大,上传失败！</font>");
}
}
else
{
echo("不支持此文件类型，请重新选择");
}
}
