force download new!
by ray, 8 years, 3 months ago
Hi
I would like to "create new image" with some modification with class.upload on the fly (not really save image) then, force download.

on example, force download using this code :
$handle = new upload($_FILES['image_field']);
header('Content-type: ' . $handle->file_src_mime);
header("Content-Disposition: attachment; filename=".rawurlencode($handle->file_src_name).";");
echo $handle->Process();
die();

i just try many combination, but i can't modify the image with upload class.

some body help me.
thanks

You don't have any image modification in your code above.

Anyhow, you can check the logs to see what's going on.Reply

Sorry, miss communication
i mean, i use code base on that code, but not working.

here my code
include('lib/class.upload.php');
$file = "image.jpg";
$files = "new-image.jpg";

$handle = new upload($file);
if ($handle->uploaded) {
 if ($handle->processed) {
	$handle->file_new_name_body   = $files;
	$handle->image_resize         = true;
	$handle->image_y              = 400;
	$handle->image_ratio_x        = true;
	header('Content-Type: application/octet-stream');
	header('Content-Disposition: attachment; filename='.basename($files));		
	$handle->process("$file");					
	echo $handle->Process();
	die();		
	
  } else {
	echo 'error : ' . $handle->error;
 }
}

that code download same image as original without modification.Reply

I just noticed, your code is incorrect, you call process() twice, and wrongly check on processed too soon. Try this:

include('lib/class.upload.php');
$file = "image.jpg";
$files = "new-image.jpg";

$handle = new upload($file);
if ($handle->uploaded) {
  $handle->file_new_name_body   = $files;
  $handle->image_resize         = true;
  $handle->image_y              = 400;
  $handle->image_ratio_x        = true;
  header('Content-Type: application/octet-stream');
  header('Content-Disposition: attachment; filename='.basename($files));						
  echo $handle->process();
  die();		
} else {
  echo 'error : ' . $handle->error;
}

I am afraid you need to try harder. Instead of outputing the image in the browser, try first to output it on disk, and check the logs produced by the class (output $handle->log). Once it works on disk, output the image in the browserReply
