＝＝＝＝＝＝ios端结束，再看下web端＝＝＝＝＝＝＝

index.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title>测试</title>
<script type="text/javascript">
function uploads(){
sendCommand("open");
}
function sendCommand(cmd){
var url = "gallery:"+cmd;
document.location = url;
}
</script>
</head>
<body>
<a href="#"><img src="upload.jpg" alt="上传按钮" onclick="uploads();" /></a>
</body>
</html>

upload.php

<?

$uploaddir = $_SERVER["DOCUMENT_ROOT"].'/test/upload/'; //这个目录必须得有权限才行。

$file = basename($_FILES['userfile']['name']);

$uploadfile = $uploaddir . $file;

if(move_uploaded_file($_FILES['userfile']['tmp_name'],$uploadfile)){

echo "OK";

}else{

echo "ERROR";

}

?>

所有的工作都完成了。

下面附图。





图片1是 上传图片的按钮，随便找了个图片代替的上传按钮。





图片2是我的相册





图片3是选择图片





图片4是剪切图片，当按choose的时候，图片就可以上传到服务器了。





图片5是已经上传好的图片，看路径。

好了，写完了～～
