[SOLVED] imagecreatefromjpeg() has filesize issues ?

[iPixel]

Ok here is my upload script.

 

Basically it uploads the original file to upload/large a thumbnail file to upload/thumbs and an enlarge file to upload/enlarge...

 

the code ! - Sorry if formatting sux

if(isset($_POST['Submit']))

{
$size = 100; // the thumbnail height
$size2 = 500; // the enlarged height

$filedir = 'upload/large/'; // the directory for the original image
$enlargedir = 'upload/enlarge/'; // the directory for the enlarge image
$thumbdir = 'upload/thumbs/'; // the directory for the thumbnail image
$prefix = get_rand_id(5); // the prefix to be added to the original name

$maxfile = '8000000';
$mode = '0666';

$userfile_name = $_FILES['image']['name'];
$userfile_tmp = $_FILES['image']['tmp_name'];
$userfile_size = $_FILES['image']['size'];
$userfile_type = $_FILES['image']['type'];

if($userfile_size >= $maxfile)
	{
	?>
		<center><br /><br /><br />
		<font color="#FF0000">The picture file you are trying to upload exceeds the 10MB limit. Please decrease the filesize and try again. Thank You!.</font><BR />

Now the issue is ... if u look at the // Start Enlarge Resize portion ....

the echoes work up to Got Here 2b... so my assumption is that imagecreatefromjpeg() is the issue here.

 

Everything works just fine as long as the image filesize is no bigger then 1MB.... when i try to upload larger filesizes like 3 + the // Start Enlarge Resize portion doesnt go through all the way and stops to a halt at that function.

 

Anybody know about this issue whatever it may be ?

 

Could it be because im using that function twice ? cause when i flip and do Enlarge first and Thumbnail second ..

the thumbnail doesnt get uploaded as opposed to the enlarge.

 

Thanks

Could this be because im trying to pull the original file twice ?

$sizes = getimagesize($prod_img);

and the again in the // Enlarge Resize Section ?

$xsizes = getimagesize($prod_img);

[iPixel]

I just came across this ...

 

http://bugs.php.net/bug.php?id=42656&edit=1

 

how do i fix this if that could be the problem !

 

my memory_limit is at 64M and both post_max_size and upload_max_filesize are set to 8M.

it sounds like you have isolated the problem to file size. perhaps a file upload size limitation is truncating your files so that they are not valid? but it seems to me they would upload completely or fail completely, not end up with a partial upload. also, you're using imagecreatefromjpeg(). is $prod_image always a jpeg?

 

From your link: Do you have error reporting turned on?

[iPixel]

error_reporting  6135 whatever that means =X.

 

yeas $prod_img is always JPG.

 

i dunno if its a memory limit problem cause it fails on a 3.7MB file when my upload and post limit is at 8M

 

my memory_limit is at 64M and both post_max_size and upload_max_filesize are set to 8M.

 

Thanks for taking a look...

[iPixel]

Oh yea ! it's always soemthing silly or stupid that messes with my head ! Grrr !

 

I went and increased the memory_limit to 128M and everything works just fine.

 

Thanks for the help!
