testupfile2.php

<&#63;php
header('Content-type:text/html;charset=utf-8');
include_once 'includes/common.inc.php';
 if(!empty($_FILES['upfile'])){
 //文件格式
 $image=array('image/jpg',
   'image/jpeg',
   'image/png',
   'image/pjpeg',
   'image/gif',
   'image/bmp',
   'image/x-png'
 );
$updir=$_SERVER['DOCUMENT_ROOT'].$_config['g']['baseUrl'].'/attached/images/';
$upfile=$_FILES['upfile'];
$name=$upfile['name'];
$ext=substr($upfile['name'],strpos($upfile['name'],'.'));
$upname=md5(time().rand(1, 1000)).$ext;
$type=$upfile['type'];
$size=$upfile['size'];
$tmp_name=$upfile['tmp_name'];
$error=$upfile['error'];
$ok=0;
 foreach ($image as $key=>$value) {
 if($type==$value)$ok=1;
 }
 if($ok=='1' && $error=='0'){
 move_uploaded_file($tmp_name,$updir.$upname);
 //echo '<br>'.$tmp_name.'<br>'.$upname.'<br>'.$updir.'<br>'.$ext.'上传成功';
 //echo '上传成功';
 echo $upname;
 //$im=$updir.$upname;
 //echo $im;
 //echo '<img src='.$updir.$upname.' />';
 //$views->assign('image',$upname);
