Ok, I just have a very simple test setup here:
http://www.nathanrutman.com/temp/sim...load-test.html

simple-upload-test.html:
Code HTML4Strict:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>PHP Form/Email Test</title>
 
<style type="text/css">
    label {
        display: block;
    }
 
    input, textarea {
        display: block;
    }
</style>
 
</head>
 
<body>
 
<form action="simple-exec.php" method="post">
    <p><label>Attachment: <input type="file" name="thefile"></label></p>
    <p><input type="submit"></p>
</form>
 
</body>
</html>

simple-exec.php:
Code PHP:
<?php
 
$fileatt =            $_FILES['thefile']['tmp_name'];
$fileatt_type =        $_FILES['thefile']['type'];
$fileatt_name =        $_FILES['thefile']['name'];
 
if (is_uploaded_file($fileatt)) {
    echo "file received";
} else {
    echo "file not received";
}
 
?>

It comes back, "file not received"...shouldn't this be fairly simple? :-)

Thanks!
