PHP: Use temporary image file on another page.
<p>I let the user upload an image... it creates a temp file but I do not want to move it 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>
