Ajax & PHP 边学边练 之五 图片处理_PHP教程

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：

Copy to Clipboard引用的内容：[www.bkjia.com] //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{
?>
br />"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">









}
}
}
}
?>

上面代码最后部分的doneloading 函数就是用来显示图片及修改图片尺寸大小。其中会用到thumb.php，它会在images目录中生成出源图片的大、中、小三个尺寸，有兴趣可以研究一下。欢迎大家拍砖～
