PHP Image Upload Form - not working .. yet no error **solved ... **

[techiefreak05]

A while back, I found an image upload form that i had no use for.. but now I'm wrapping up the building of my website and am in the proccess of finalizing  the last parts, like images. but im having trouble with this code.. it doesnt give me an error, but it doesnt upload:

[code]<?php

//print_r($_POST);

if($_POST["action"] == "Upload Image")
{
unset($imagename);

if(!isset($_FILES) && isset($HTTP_POST_FILES))
$_FILES = $HTTP_POST_FILES;

if(!isset($_FILES['image_file']))
$error["image_file"] = "An image was not found.";


$imagename = basename($_FILES['image_file']['name']);
echo $imagename;

if(empty($imagename))
$error["imagename"] = "The name of the image was not found.";

if(empty($error)){
$newimage = "files/uploads/$_SESSION[username]/images/" . $imagename;
echo $newimage;
$result = @move_uploaded_file($_FILES['image_file']['tmp_name'], $newimage);
if(empty($result))
$error["result"] = "There was an error moving the uploaded file.";
}
}
?>
<div id="form">
<form method="POST" enctype="multipart/form-data" name="image_upload_form" action="<?$_SERVER["PHP_SELF"];?>">
<p><input type="file" name="image_file" size="20"></p>
<p><input type="submit" value="-Upload-" name="action"></p>
</form>
</div>[/code]
