PHP: Use temporary image file on another page.
<p>I let the user upload an image. It then creates a temp file but I don't want to move it to a permanent address yet because I want to take them to <code>cropphoto.php</code> where they can create a thumbnail from it. If they exit out of the window before this I don't want it to be saved.</p>

<p>How would I pass the temporary image from the following script:</p>

<pre><code>&lt;?php 
include_once '../dbconnect.php'; 
$protocol = !empty($_SERVER['HTTPS']) ? 'https://' : 'http://';
$domain = $protocol. $_SERVER['SERVER_NAME'];

function findexts ($filename) {
    $filename = strtolower($filename) ;
    $exts = split("[/\\.]", $filename) ;
    $n = count($exts)-1;
    $exts = $exts[$n];
    return $exts;
}

$SubcatID = $_POST['SubcatID'];
if (empty($SubcatID)){
    $SubcatID = -1;
}

$ext = findexts ($_FILES['photo']['name']) ; 
if ($ext == "jpg" || $ext == "jpeg") {
    $return = 'cropphoto.php?PhotoID='.urlencode($_FILES['photo']['name']);
    header("Location: $return");
} 
else {
    echo "ERROR: The image must be a JPEG";
    exit;
}
?&gt; 
</code></pre>

<p>The current url paramater im using just passes the image name but I can't find the temp folder it is in.</p>
