Uploading file to FTP using PHP - will not write to server

Question

I'm trying to upload a file to an FTP server. It gets caught in the if statement which states that the directory must be chmode 777 however I have manually chmode 77 every directory in the ftp as well as adding a function in the code.

Secondly, I'd like to ask about the .tmp files that are created once an upload process has begun. Are they uploaded to the FTP? If so, do I need to also allow access for .tmp files along with .mp3 files? I'm pretty unaware of what their use in the process actually is so if anyone could take the time to explain it that'd be very helpful.

some variable contents:

$upload_path = /htdocs/site2/telemessages/en/Apologies
$_FILES['userfile']['tmp_name'] = /tmp/phpwkfxrW

Here is the code I'm using to pass the file to the FTP:

 $ftp_server="***********"; 
 $ftp_user_name="************"; 
 $ftp_user_pass="***********"; 

 // set up basic connection 
 $conn_id = ftp_connect($ftp_server); 

 // login with username and password 
 if(ftp_login($conn_id, $ftp_user_name, $ftp_user_pass)){

// Configuration - Your Options
      $allowed_filetypes = array('.mp3','.tmp'); // These will be the types of file that will pass the validation.
      $max_filesize = 2097152; // Maximum filesize in BYTES (currently 2MB).

      $cutName = substr($_SESSION['dir'], 0, -1); 

      $upload_path = "htdocs/site/telemessages/en/". $_SESSION['dir'];
      echo "upload path: ".$upload_path; // The place the files will be uploaded to (currently a 'files' directory).


   $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); // Get the extension from the filename.

   // Check if the filetype is allowed, if not DIE and inform the user.
   if(!in_array($ext,$allowed_filetypes))
      die('The file you attempted to upload is not allowed.');

   // Now check the filesize, if it is too large then DIE and inform the user.
   if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
      die('The file you attempted to upload is too large.');

   // Check if we can upload to the specified path, if not DIE and inform the user.
   if(!is_writable($upload_path))
      die('You cannot upload to the specified directory, please CHMOD it to 777.');

   // We'll start handling the upload in the next step
   echo"FORCE: ".$_FILES['userfile']['tmp_name'];
       //Upload the file to your specified path.
  $result = move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename);


    if(!$result)
                {
                    return -1;
                }
                else
                {
                    echo $result;
                    //SET PROPER READ PERMISSIONS

                    $result2 = chmod($upload_path, 0777);
                    echo "Result: ".$result2;
                   } 

}else{
echo "login failed";
}

Thanks for any help in advance.

$upload_path = "htdocs/site/telemessages/en/". $_SESSION['dir']; - should this have a leading "/"? — Paul Bailey, Jul 22 '13 at 16:52

At first glance, there are a couple of things that could be causing your trouble.

$upload_path = /htdocs/site2/telemessages/en/Apologies

I'm going to assume that actually has quote marks around it in your code. If not, that needs to be fixed.

Possibilities:

The web server doesn't have access to that directory. I know that some server farms use NFS across multiple servers and there can be weird permission things that happen. You might want to check with your server company.
It is possible that /htdocs/site2/telemessages/en/Apologies is actually a file and not a directory, which could cause an issue.
Paul Bailey's comment above: You might be trying to reference a path off the system root directory, when it should be off the application root directory. Hence his comment about the leading /.
