I use an HTML form to call a javascript function that uses a PHP script to upload the image file chosen on the form to a MySQL database as a blob.

I use firebug to debug the output and the PHP output just says empty array and it cannot find the variables:
array(0) {
}
<br />
<b>Notice</b>:  Undefined index: userfile in <b>C:\wamp\www\portal\upload.php</b> on line <b>6</b><br />

Firstly this is my AJAX code - say if the PHP or HTML is required please.
Cheers anyone


var file = document.getElementById("userfile").value;
	var filename = document.getElementById("name").value;
	connection.open("POST", "upload.php", true);
	connection.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
	connection.setRequestHeader("Content-length", file.length);
	connection.setRequestHeader("connection", "close");
	connection.send(file);

I don't think you should store image in the database instead store a reference

If I stored a reference then I could upload details via the GET method - something I think I could do.
Need to have a look at tutorial posted before though.
Cheers
