Creating temp file and transfering through ftp

[AtomicRax]

From the beginning, the user accesses my website and uploads an image.

 

Currently I'm using SimpleImage.php available at http://www.white-hat-web-design.co.uk/articles/php-image-resizing.php to resize uploaded pictures.

 

I create two copies, a regular size and a thumbnail size. Then I transfer the converted files through FTP to my storage server. The regular size works great, but the thumbnail transfers as a blank file. I don't want to save the files on the non-storage server at all, so I'm trying to work with temporary files.

 

include('./SimpleImage.php');

// A few variables
$file_name = basename($_FILES['photo1']['name']);
$random_digit=mt_rand(111111111,2147483647);

// New file name
$new_file_name = $userInfo['id'].'_'.$random_digit.$random_digit.'_'.substr($file_name, -5);

// Paths to temporary files
$target_path = $_FILES['photo1']['tmp_name'];
$thumb_path = tmpfile();

// Start SimpleImage and load temp file
$simImage = new SimpleImage();
$simImage->load($target_path);

// Get the temp image dimensions
list($width, $height) = getimagesize($target_path);

// Resize the file if it's too tall
if ($height > $var['maxPhotoHeight']) {
   $simImage->resizeToHeight($var['maxPhotoHeight']);
   $simImage->save($target_path);
   }

// Get the newly resized image dimensions
list($width, $height) = getimagesize($target_path);

// Resize the image if it's too wide
   if ($width > $var['maxPhotoWidth']) {
   $simImage->resizeToWidth($var['maxPhotoWidth']);
   $simImage->save($target_path);
   }

// Resize for thumbnail width
   $simImage->resizeToWidth($var['thumbWidth']);
   $simImage->save($thumb_path);

// Get thumbnail dimensions
list($width, $height) = getimagesize($thumb_path);

// Resize the thumbnail if it's too tall
if ($height > $var['thumbHeight']) {
   $simImage->resizeToHeight($var['thumbHeight']);
   $simImage->save($thumb_path);
   }

// Was told this was important, but I've tried with and without it and got the same result
fseek($thumb_path,0);

// Perform File Transfer
ftpTransfer($target_path, "$new_file_name");
ftpTransfer($thumb_path, "thumbs/$new_file_name");



// My Simple FTP Transfer Function:
function ftpTransfer($source, $name) {
global $ftp;

$ftpMeta = "ftp://" . $ftp['user_name'] . ":" . $ftp['user_pass'] . "@" . $ftp['server'] . $ftp['dir'] . $name;
$ftpData = file_get_contents($source);

file_put_contents($ftpMeta, $ftpData);
}

 

Like I said, the regular sized image works great!! the thumbnail file is only created on the storage server but it has a 0kb file size. I'm sure it has to do with me working with a temporary file. tmpfile() claims to remove the file after it's closed, so maybe by using the Save feature in SimpleImage, it's closing the file and then the server automatically removes the temporary file?

 

SimpleImage has a feature where I can write the image output [possibly to a file] using $simImage->output() for the data. If that helps with a solution? I don't know.

 

I know it might be complicated, but any help is appreciated!

i suggest that you copy the tmp file to a directory, perform alterations, upload that file via ftp, then unlink() the file. i think using temp file is the problem.

I've changed $thumb_path to this:

 

$thumb_path = tempnam("/tmp", $new_file_name);

 

and then added an unlink() after it uploads the file, and it works now! Thanks.
