[RESOLVED] Why won't download work?

[harmony_wsc]

I am using the following code to download files:

<?
	session_start();
	define("EP_Root","../");
	if( isset($_GET["attachmentid"]) )
	{
		$AttachmentID = $_GET["attachmentid"];
		include("../bll/attachment.class.php");
		$attachment = new Attachment();
		$Attachments = $attachment->LoadAttachment($AttachmentID);
		switch ($Attachments["ContentType"]) {
            case "pdf": $ctype="application/pdf"; break;
            case "exe": $ctype="application/octet-stream"; break;
            case "zip": $ctype="application/zip"; break;
            case "doc": $ctype="application/msword"; break;
            case "xls": $ctype="application/vnd.ms-excel"; break;
            case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
            case "gif": $ctype="image/gif"; break;
            case "png": $ctype="image/png"; break;
            case "jpe": 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("Cache-Control: private",false);
		header("Content-Type: $ctype");
		header("Content-Disposition: attachment; filename=\"".$Attachments["OriginalFileName"].".".$Attachments["ContentType"]."\";");
		header("Content-Transfer-Encoding: binary");
		header("Content-Length: ".$Attachments["FileSize"]);
		set_time_limit(0);
		@readfile($Attachments["FilePath"].$AttachmentID.".".$Attachments["ContentType"]) or die ("File not found");
		exit;
	}
?>

I am using FF and I get the dialog box to open or save the file. Neither option works. I try to download files to my desktop. It creates a .part file and then gives me an error that it cannot read the .part file.

Am I missing something?

Try to echo:
$Attachments["FilePath"].$AttachmentID.".".$Attachments["ContentType"]
and $Attachments["FileSize"]

A .part file is a file that has started to download, but no finished.
You have set time limit.

Try downloding a very small file, and see if there might be a size problem.
For some reason the transfer is broken.

Try to remove the @
from @readfile(
and see if you get any more error report.

Put the display test here:

            case "jpg": $ctype="image/jpg"; break;
            default: $ctype="application/force-download";
        }
$Attachments["FilePath"].$AttachmentID.".".$Attachments["ContentType"]
echo '<br>';
echo $Attachments["FileSize"];
exit();
        header("Pragma: public");
        header("Expires: 0");

I copied your code in and my output is
../Uploads/14.html
351.00

This is a very small file. I also removed the @ in front of readfile and that did not make a difference.

I can get this to work in IE by adding session_cache_limiter('public'); to the first line of the file. It still does not work in FF. I get an error stating C:\Documents and Settings\har\Desktop\test.pdf.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.

Any ideas?

<?
session_cache_limiter('public');
	session_start();
	define("EP_Root","../");
	if( isset($_GET["attachmentid"]) )
	{
		$AttachmentID = $_GET["attachmentid"];
		include("../bll/attachment.class.php");
		$attachment = new Attachment();
		$Attachments = $attachment->LoadAttachment($AttachmentID);
		switch ($Attachments["ContentType"]) {
            case "pdf": $ctype="application/pdf"; break;
            case "exe": $ctype="application/octet-stream"; break;
            case "zip": $ctype="application/zip"; break;
            case "doc": $ctype="application/msword"; break;
            case "xls": $ctype="application/vnd.ms-excel"; break;
            case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
            case "gif": $ctype="image/gif"; break;
            case "png": $ctype="image/png"; break;
            case "jpe":
            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("Cache-Control: private",false);
		header("Content-Type: $ctype");
		header("Content-Disposition: attachment; filename=\"".$Attachments["OriginalFileName"].".".$Attachments["ContentType"]."\";");
		header("Content-Transfer-Encoding: binary");
		header("Content-Length: ".$Attachments["FileSize"]);
		set_time_limit(0);
		readfile($Attachments["FilePath"].$AttachmentID.".".$Attachments["ContentType"]) or die ("File not found");
		exit;
	}
?>

I got it to work in both FireFox and Internet Explorer using the following code.

<?
	session_cache_limiter('public');
	session_start();
	define("EP_Root","../");
	if( isset($_GET["attachmentid"]) )
	{
		$AttachmentID = $_GET["attachmentid"];
		include("../bll/attachment.class.php");
		$attachment = new Attachment();
		$Attachments = $attachment->LoadAttachment($AttachmentID);
		switch ($Attachments["ContentType"]) {
            case "pdf": $ctype="application/pdf"; break;
            case "exe": $ctype="application/octet-stream"; break;
            case "zip": $ctype="application/zip"; break;
            case "doc": $ctype="application/msword"; break;
            case "xls": $ctype="application/vnd.ms-excel"; break;
            case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
            case "gif": $ctype="image/gif"; break;
            case "png": $ctype="image/png"; break;
            case "jpe":
            case "jpeg":
            case "jpg": $ctype="image/jpg"; break;
            default: $ctype="application/force-download";
        }
		$filename = $Attachments["FilePath"].$AttachmentID.".".$Attachments["ContentType"]; 
		$content_len = filesize($filename); 
		$output_file = $Attachments["OriginalFileName"].".".$Attachments["ContentType"];

	@ob_end_clean(); 
	@ini_set('zlib.output_compression', 'Off'); 
	header('Pragma: public'); 
	header("Expires: 0");
	header('Cache-Control: no-store, no-cache, must-revalidate'); // HTTP/1.1 
	header('Cache-Control: pre-check=0, post-check=0, max-age=0'); // HTTP/1.1 
	header("Cache-Control: public");
	header("Content-Description: File Transfer");
	header('Content-Transfer-Encoding: none'); 
	header('Content-Type: '.$ctype.'; name="' . $filename . '"');
	header('Content-Disposition: attachment; filename="' . $output_file . '"'); 
	header("Content-Transfer-Encoding: binary");
	header("Content-length: $content_len"); 
	set_time_limit(0);
	readfile($filename); 
	exit(); 
}
?>

Thanks for all your help.
