Sample6_1.php 中创建Form: 
代码如下:
//显示上传状态和图片 
 
//上传文件需要定义enctype,为了显示图片将target设为uploadframe 
 
代码如下:
function uploadimg(theform){ 
//提交Form 
theform.submit(); 
//在showimg 中显示上传状态 
setStatus ("Loading...","showimg"); 
} 
//上传状态函数 
function setStatus (theStatus, theObj){ 
obj = document.getElementById(theObj); 
if (obj){ 
obj.innerHTML = "" + theStatus + ""; 
} 
} 
代码如下:
//提供图片类型校验 
$allowedtypes = array("image/jpeg","image/pjpeg","image/png", "image/x-png","image/gif"); 
//文件存放目录 
$savefolder = "images"; 
//如果有文件上传就开始干活 
if (isset ($_FILES['myfile'])){ 
//检查上传文件是否符合$allowedtypes类型 
if (in_array($_FILES['myfile']['type'],$allowedtypes)){ 
if ($_FILES['myfile']['error'] == 0){ 
$thefile = "$savefolder/".$_FILES['myfile']['name']; 
//通过move_uploaded_file上传文件 
if (!move_uploaded_file($_FILES['myfile']['tmp_name'], $thefile)){ 
echo "There was an error uploading the file."; 
} 
else{ 
?>
