Getting the upload object directly

[pczjrh]

Hi,
how do you get the upload object directly?

I’m trying to pass the object into getimagesize() and return some image dimensions.
When this code runs during upload the file is reported as being missing. Which is why the getimagesize() function is returning nothing.
This code is part of my_post_process($form), so I assume by this point the file should have been moved into place (which I assume it has as the URL is correct and file renamed).

Any thoughts as to why this isn’t working?
Thanks in advance.
Jason

$file = $form->getValue('iphorm_1_3');
$file_url=preg_replace('/[^a-zA-Z0-9:.\/_-]/','%20',$file[0]['url']);
if (file_exists((string)$file_url)){
$file_exists="File Exists";
}else{
$file_exists="File isn't there!";
}
$ImageDims = getimagesize((string)$file_url);
$width = $ImageDims[0];
$widthInt = (int)$width;
$height = $ImageDims[1];
$heightInt = (int)$height;
