Topic: Bypass Temp Directory
I need to know how to bypass the temp directory when downloading a file. I know its possible because other web based ftp's do it.
Re: Bypass Temp Directory
The standard PHP function ftp_get() downloads the files from
the FTP server to the web server's /temp directory. There is no way
around using a local file, unless you write your own ftp_get function;
an example is posted on the PHP website - I didn't try it out:
http://www.php.net/manual/en/function.ftp-get.php#72603
Re: Bypass Temp Directory
the buffer in the socket pair is only about 364 bytes. So it doesn't work for files larger than that size.
Theres
gotta be another way... How to big file websites do this? They dont
move the file over to a temp directory first. This seems like it would
be easy, but its not.
Is there a way to create just a link to the ftp
with the user and pass? like
ftp://username:password@ftpserver.com/directory/file
That seems like it would be easy, but I'm not very good at php and I wouldn't know what to change.
Re: Bypass Temp Directory
Hi.
I writed a method, using custom headers and readfile function for read ftp file content. On filesystem.inc.php:
function ftp_downloadfile($directory, $entry) {
global $net2ftp_globals, $net2ftp_result, $net2ftp_settings;
$conn_id = ftp_openconnection();
if ($net2ftp_result["success"] == false) { return false; }
// Decrypt password
if (isset($_SESSION["net2ftp_password_encrypted_" . $net2ftp_globals["ftpserver"] . $net2ftp_globals["username"]]) == true) {
$net2ftp_password = decryptPassword($_SESSION["net2ftp_password_encrypted_" . $net2ftp_globals["ftpserver"] . $net2ftp_globals["username"]]);
} else {
$net2ftp_password = decryptPassword($net2ftp_globals["password_encrypted"]);
}
// Direct download
header("Content-type: application/force-download");
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$entry."\"");
readfile("ftp://".$net2ftp_globals["username"].":".
$net2ftp_password."@".
$net2ftp_globals["ftpserver"].":".
$net2ftp_globals["ftpserverport"].
$directory.$entry);
return false;
}Maybe it'is not perfect, but it's faster and works for me 
See ya

Thank you so much for the MOD, I was looking for something like this for long time !
All the best!
Re: Bypass Temp Directory
By far one of the most important and greatest snips of code to add into the FTP client. 100% amazing 
well done.
For people that dont know how to use this piece of code, go to the file he told you to edit, search the function and take out and replace the whole function code.
Works a treat
Now can someone write an upload equivalent to this?

Re: Bypass Temp Directory
Hello everyone,
Thank you for this great snip of code, I do have one question though: when I add this code, all files are downloaded as 0kb in size. Is there any workaround for this?
Thanks in advance,
Jim Morris
Re: Bypass Temp Directory
Hi everybody,
This is exactly what I need, but I have the same problem as JimMorris has, the dowloaded files are only 1kb and cannot be opened after dowloading. Any ideas?
Thanks and cheers !
Re: Bypass Temp Directory
Thank you for the funciton, i've noticed that the files are downloading in the right way only in the root ftp directory.
Using subfolders I have the same problem of the other people.
The issue is that the function you worte works correctly if you change the parameters in ftp_downloadfile
because $directory miss a '/' at the end of his name.
Solution:
In modules\downloadfile there is downloadfile.inc.php that contains only the following function
function net2ftp_module_sendHttpHeaders() {
// --------------
// This function sends HTTP headers
// --------------
global $net2ftp_globals, $net2ftp_settings;
if ($net2ftp_settings["functionuse_downloadfile"] == "yes") {
//replace
//ftp_downloadfile($net2ftp_globals["directory"], $net2ftp_globals["entry"]);
//with
ftp_downloadfile($net2ftp_globals["directory"]."/", $net2ftp_globals["entry"]);
//and that's all
}
else {
$errormessage = __("This function has been disabled by the Administrator of this website.");
setErrorVars(false, $errormessage, debug_backtrace(), __FILE__, __LINE__);
return false;
}
} // end net2ftp_sendHttpHeaders

It argues that a Greek naval blockade during the Trojan War kept Trojans on the European shore from intervening, and that they subsequently escaped to Italy where they were called Etruscans.
