I am new to php.I was trying to upload a file but i got an HTML table as result with undefined content type.Here is my code
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link href="fileuploader.css" rel="stylesheet" type="text/css">
<script src="fileuploader.js" type="text/javascript"></script>
<script>
function createUploader(){
// alert("hhh");
var uploader = new qq.FileUploader({
element: document.getElementById('file-uploader-demo1'),
action: 'php.php',
//action: 'addinvoice.php',
debug: true
});
}
// in your app create uploader as soon as the DOM is ready
// don't wait for the window to load
window.onload = createUploader;
</script>
</head>
<body>
<form action="php.php" method="POST" enctype="multipart/form-data"/>
<table border="0" align="center">
<tr >
<td>
<div id="file-uploader-demo1">
<noscript>
<p>Please enable JavaScript to use file uploader.</p>
<!-- or put a simple form for upload here -->
</noscript>

Any help would be appreciated.I changed my php.ini and make upload_max_filesize = 60M
post_max_size = 60M.I also checked for($_post) for content length.It doesnt work.I also printed print_r($_server).But the content length is not printed as the output.
