使用iOS6 WebKit上传照片，处理没有响应

Question

由于iOS6现在支持照片/视频上传，我想在我的移动应用中使用它。出现问题，即照片或视频都没有上传到上传脚本提供的指定文件夹。不确定我做错了什么。

以下是我用来抓取文件或捕获文件的内容......

<form action="" method="POST">
<input type="file" accept="image/* capture="camera"><br><br>
<input type="submit" value="Upload" class="login-button"/>
</form>

这会在同一页上处理照片......

<?php
 function findexts ($filename) 
 { 
 $filename = strtolower($filename) ; 
 $exts = split("[/\\.]", $filename) ; 
 $n = count($exts)-1; 
 $exts = $exts[$n]; 
 return $exts; 
 } 
  $ext = findexts ($_FILES['uploaded']['name']) ; 
 $ran = rand () ;
 $ran2 = $ran.".";
 $target = "files/";
 $target = $target . $ran2.$ext; 
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
 {
 echo "The file has been uploaded as ".$ran2.$ext;
 } 
 else
 {
 echo "Sorry, there was a problem uploading your file.";
 }
 ?>
