上传图片函数 uploadimg：
代码如下:

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 = "
process_upload.PHP 提供文件上传功能：
setStatus ("Loading...","showimg");
}
//上传状态函数
function setStatus (theStatus,theObj){
obj = document.getElementById(theObj);
if (obj){
obj.innerHTML = "
";
}
}
}
}
process_upload.PHP 提供文件上传功能：
代码如下:
PHP
//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{
?>
