Readfile() Multiple Picture Download

[sroberge]

I've been avoiding asking for days figuring that there is something that I am missing.  I can't seem to figure this one out. 

 

I have tried everything that I can think of or find.  Can someone please help?  Below is an outline of the code:

 

This page is the actual form that the email recipient goes to, to select the pictures that they would like to download.  The ‘%PICS%’ variable is replaced with the image path to the images in the users directory also creating a checkbox for the user to select the image.

 

<form method="post" action="index.php?action=download">

%PICS%

            <input type="submit" name="submit" value="Download">

</form>

 

So far, simple enough.  On submit this page submits back to itself and falls into this chuck of code:

 

  require('../../uploader/force-download.php');

 

  $action = (isset($_GET['action']) ? $_GET['action'] : '');

 

  if ($action == 'download') {

 

            $count = count($_POST['pic']);

            for($i = 0; $i < $count; $i++) {

                        $filename[] = $_POST['pic'][$i];

            }

 

            download($filename);

 

This part of the code places all the user selected images into an array $filename then passes it to the function download located in force-download.php.  Again, simple enough.

 

Force-download.php:

 

function download($array) {

 

            for($i = 0; $i < count($array); $i++) {

                        $filename = $array[$i];

 

                        if(ini_get('zlib.output_compression'))

                                    ini_set('zlib.output_compression', 'Off');

 

                        $file_extension = strtolower(substr(strrchr($filename,"."),1));

 

                        switch( $file_extension ) {

                                    case "pdf": $ctype="application/pdf"; break;

                                    case "zip": $ctype="application/zip"; break;

                                    case "gif": $ctype="image/gif"; break;

                                    case "png": $ctype="image/png"; break;

                                    case "jpeg":

                                    case "jpg": $ctype="image/jpg"; break;

                                    default: $ctype="application/force-download";

                        }

 

                        header('Pragma: public');

                        header('Expires: 0');

                        header('Cache-Control: must-revalidate, post-check=0, pre-check=0');

                        header('Content-Description: File Transfer');

                        header("Cache-Control: private",false

                        header("Content-Type: $ctype");

                        header("Content-Disposition: attachment; filename=\"".basename($filename)."\";" );

                        header('Content-Transfer-Encoding: binary');

                        header('Content-Length: ' . filesize($filename));

                        ob_clean();

                        flush();

                        readfile($filename);

            }

}

 

I can only get the first picture to download and not the rest.

 

Any help would be greatly appreciated!!!
