`Here is my HTML Code :

<html>
<head>
<title>Welcome</title>
</head>

<body>
<form enctype="multipart/form-data" action="upload.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile_1" type="file" /><br />
Choose a file to upload: <input name="uploadedfile_2" type="file" /><br />
<input type="submit" value="Upload Files" />
</form>
</body>
</html>

And Below is PHP :

<?php
$ftp_server = "94.xx.1.xxx";
$ftp_username   = "anxxxxxx";
$ftp_password   =  "xxxxxxxxx";

$conn_id = ftp_connect($ftp_server) or die("could not connect to $ftp_server");

if(@ftp_login($conn_id, $ftp_username, $ftp_password))
{
  echo "connected as $ftp_username@$ftp_server\n";
  }
else {
  echo "could not connect as $ftp_username\n";
}

$file = $_FILES["uploadedfile_1"]["name"];
$file2 = $_FILES["uploadedfile_2"]["name"];

$remote_file_path = "ansxxxx@94.xx.1.xxx/JustForTest".$file; // This is the Folder which I've created inside the FTP 
$remote_file_path2 = "ansxxxx@94.xx.1.xxx/JustForTest".$file2; // This is the Folder which I've created inside the FTP 

ftp_put($conn_id, $remote_file_path, $_FILES["uploadedfile_1"]["tmp_name"],FTP_ASCII);
ftp_put($conn_id, $remote_file_path2, $_FILES["uploadedfile_2"]["tmp_name"],FTP_ASCII);
ftp_close($conn_id);
echo "\n\nconnection closed";
?>


Error :

connected as anshu9453@94.23.1.139
Fatal error: Uncaught ValueError: Path cannot be empty in C:\xampp\htdocs\upload.php:22 Stack trace: #0 C:\xampp\htdocs\upload.php(22): ftp_put(Object(FTP\Connection), 'anshu9453@94.23...', '', 1) #1 {main} thrown in C:\xampp\htdocs\upload.php on line 22

It connects perfectly...but no files gets uploaded, throws the above error. I am new to php. PLEASE HELP...!

I would prefer to share the code, if anyone had done such kind of requirement.

Thanks a ton in Advance...!`

The error you saw — "ValueError: Path cannot be empty" — means ftp_put was given an empty local path. In your stack trace the third argument is '' so PHP never created a tmp file for the upload (or you referenced the wrong field). Common causes: the upload hit a size limit (MAX_FILE_SIZE or php.ini settings), the file input name doesn't match, or $_FILES contains an error code.

Short troubleshooting and fixes (try these in order):

  • Inspect what PHP actually received: print_r($_FILES); and check $_FILES['uploadedfile_1']['error'] and ['tmp_name'].
  • Remove or increase the <input name="MAX_FILE_SIZE"> while testing — that field is advisory and can make uploads fail silently if the file is bigger than the value. Also verify upload_max_filesize and post_max_size in php.ini.
  • Don’t pass the username@host as the remote file path. ftp_put expects a remote path on the FTP server (for example /JustForTest/filename.ext), not an FTP URL.

Example of the minimal safe flow (simplified):

// validate upload
if (!isset($_FILES['uploadedfile_1']) || $_FILES['uploadedfile_1']['error'] !== UPLOAD_ERR_OK) {
    var_dump($_FILES['uploadedfile_1']['error']); exit;
}
$local = $_FILES['uploadedfile_1']['tmp_name'];
$remote = '/JustForTest/' . basename($_FILES['uploadedfile_1']['name']);

ftp_pasv($conn, true);
$ok = ftp_put($conn, $remote, $local, FTP_BINARY);
if (!$ok) { /* check remote dir exists, perms, use ftp_nlist/ftp_chdir/ftp_mkdir */ }

Also heed ’s point: if you only need the file on the web server, use move_uploaded_file() instead of FTP. If you must move to a separate host, check remote folder permissions, test with a very small file, and consider SFTP (ssh2) for security. If these checks still fail, paste the output of print_r($_FILES) and the exact php.ini upload limits for further diagnosis.

What exactly does upload.php look like? It looks like there is an error on line 22 of upload.php. It looks as if the path is invalid in your ftp_put() function. Check your values for $remote_file_path and $remote_file_path2.

Also, this is a very, very insecure way of doing file uploads. Why are you doing it this way instead of as a POST forum with PHP uploads?

Non logic operation to upload file. file transfer protocol(ftp) can be operated after connecting two or more devices to obtain ftp IP to perform a specific task of transferring a file from one device to another. eg ftp://10.165.1:2541
