Alright I am trying to have a PHP FTP Upload Form that allows the user to create the directory folder for where they want to upload there files to.

example:
Main Directory: vainsoft.com
There directory: vainsoft.com/modeling or vainsoft.com/photography


But I dont want them to be able to upload things into the main directory, only sub-directories, is that possible with this coding that I have:
[codebox]
<?
//uses $_FILES[] global array
//see manual for older PHP version info

//This function will be used to get the extension from the filename
function get_extension($file,$length=-1){
$p = strrpos($file,".");
$p++;
if($length!=-1){
$ext = substr($file,$p,$length);
}
if($length==-1){
$ext = substr($file,$p);
}
$ext = strtolower($ext);
return $ext;
}

//Not good practice, but here anyway
//change to suit your needs
//also some have to be set in the ini
//for this to correctly work

//2meg max
ini_set("upload_max_filesize","100M");

//turn on file uploads
ini_set("file_uploads","1");

//set your temp dir
ini_set("upload_tmp_dir","/tmp");

//set post size large enough to accomidate
//3 100meg files and some overhead
ini_set("post_max_size","180M");

?>
<html>
<head>
<title>VainSoft - Upload Form</title>
</head>
<body>
<?
//check to see if we have submited yet
if($_POST["submit"]!="submit"){
//not yet so lets make the form
?>
<p>Upload Images here, 10 images at a time, hit back after upload to upload more. (100M MAX)</p>
<p>
<form name="fileup" method="post" enctype="multipart/form-data" action="<? echo $PHP_SELF; ?>">
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<br>
<!-- change below to your max -->
<input type="hidden" name="MAX_FILE_SIZE" value="1000000000">
<input type="submit" value="submit" name="submit">
</form>
</p>
<?
}
//see if we have submited and that the files array has been set
if(($_POST["submit"]=="submit")&&(is_array($_FILES['userfiles']))){

$ftp_user_name="******"; //change to ftp username
$ftp_user_pass="******"; //change to ftp password
$ftp_server="******"; //change to ftp url
$ftp_dump_dir="******"; //change to destination directory

//go through all the files
for($x=0;$x<count($_FILES['userfiles']['name']);$x++){

//now we do some file checking

//check to see if file is there
if($_FILES['userfiles']['name'][$x]!="none"){
//file has a name
//check filesize
if($_FILES['userfiles']['size'][$x]!=0){
//file is larger than 0 bytes
//Check to see if it is uploaded
if(is_uploaded_file($_FILES['userfiles']['tmp_name'][$x])){
//file has been uploaded!
//let the user know their file has be uploaded
echo "file ".$_FILES['userfiles']['name'][$x]." uploaded!<br>";
//conect to ftp server
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// check connection
if ((!$conn_id) || (!$login_result)) {
echo "FTP connection has failed!<br>";
echo "Attempted to connect to $ftp_server for user $ftp_user_name";
exit;
} else {
echo "Connected to $ftp_server! <br>";
//set PASV mode
if(!ftp_pasv($conn_id,TRUE)){
echo "Could not enter PASV mode!";
}
//rename to file#_date.ext
$filename = $_FILES['userfiles']['name'][$x];
//$filename.= ".".get_extension($_FILES['userfiles']['name'][$x],3);

//change directory
if (@ftp_chdir($conn_id, $ftp_dump_dir)) {
//maybe you want to make sure we are in the correct directory
echo "Current directory is now : ", ftp_pwd($conn_id), "\n";
} else {
//you want to know if it didn't work
echo "Couldn't change directory\n";
}

//upload the file and let the user know what happened
if(ftp_put($conn_id,$filename,$_FILES['userfiles']['tmp_name'][$x],FTP_BINARY)){
echo "File ".$_FILES['userfiles']['name'][$x]." was sent successfully<br>";
echo "File was named ".$filename."<br>";
}else{
echo "There was a problem sending file ".$_FILES['userfiles']['name'][$x]."<br>";;
}
}
// close the FTP stream
ftp_close($conn_id);
}
else echo"File was not uploaded!<br>";
}
}
echo "<br>";

}//end for loop

}
//That's all folks!
?>
</body>
</html>
[/codebox]
Any help with this will be grateful.

I think I can help here but I'm not sure first take out all your html.

CODE
<html>
<head>
<title>VainSoft - Upload Form</title>
</head>
<body>

<p>Upload Images here, 10 images at a time, hit back after upload to upload more. (100M MAX)</p>
<p>
<form name="fileup" method="post" enctype="multipart/form-data" action="upload.Php">
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<input type="file" name="userfiles[]"><br>
<br>
<!-- change below to your max -->
<input type="hidden" name="MAX_FILE_SIZE" value="1000000000">
<input type="submit" value="submit" name="submit">
</form>
Save that as upload.Html

Then for the php add
CODE
<?
//uses $_FILES[] global array
//see manual for older PHP version info

//This function will be used to get the extension from the filename
Function get_extension($file,$length=-1){
$p = strrpos($file,".");
$p++;
If($length!=-1){
$ext = substr($file,$p,$length);
}
If($length==-1){
$ext = substr($file,$p);
}
$ext = strtolower($ext);
Return $ext;
}

//Not good practice, but here anyway
//change to suit your needs
//also some have to be set in the ini
//for this to correctly work

//2meg max
Ini_set("upload_max_filesize","100M");

//turn on file uploads
Ini_set("file_uploads","1");

//set your temp dir
Ini_set("upload_tmp_dir","/tmp");

//set post size large enough to accomidate
//3 100meg files and some overhead
Ini_set("post_max_size","180M");

?>

</p>
<?
//check to see if we have submited yet
If($_POST["submit"]!="submit"){
//not yet so lets make the form
?>

<?
}
//see if we have submited and that the files array has been set
If(($_POST["submit"]=="submit")&&(is_array($_FILES['userfiles']))){

$ftp_user_name="*****"; //change to ftp username
$ftp_user_pass="*****"; //change to ftp password
$ftp_server="******"; //change to ftp url
$ftp_dump_dir="/files"; //change to destination directory

//go through all the files
For($x=0;$x<count($_FILES['userfiles']['name']);$x++){

//now we do some file checking

//check to see if file is there
If($_FILES['userfiles']['name'][$x]!="none"){
//file has a name
//check filesize
If($_FILES['userfiles']['size'][$x]!=0){
//file is larger than 0 bytes
//Check to see if it is uploaded
If(is_uploaded_file($_FILES['userfiles']['tmp_name'][$x])){
//file has been uploaded!
//let the user know their file has be uploaded
Echo "file ".$_FILES['userfiles']['name'][$x]." uploaded!<br>";
//conect to ftp server
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// check connection
If ((!$conn_id) || (!$login_result)) {
Echo "FTP connection has failed!<br>";
Echo "Attempted to connect to $ftp_server for user $ftp_user_name";
Exit;
} else {
Echo "Connected to $ftp_server! <br>";
//set PASV mode
If(!ftp_pasv($conn_id,TRUE)){
Echo "Could not enter PASV mode!";
}
//rename to file#_date.Ext
$filename = $_FILES['userfiles']['name'][$x];
//$filename.= ".".Get_extension($_FILES['userfiles']['name'][$x],3);

//change directory
If (@ftp_chdir($conn_id, $ftp_dump_dir)) {
//maybe you want to make sure we are in the correct directory
Echo "Current directory is now : ", ftp_pwd($conn_id), "\and";
} else {
//you want to know if it didn't work
Echo "Couldn't change directory\and";
}

//upload the file and let the user know what happened
If(ftp_put($conn_id,$filename,$_FILES['userfiles']['tmp_name'][$x],FTP_BINARY)){
Echo "File ".$_FILES['userfiles']['name'][$x]." was sent successfully<br>";
Echo "File was named ".$filename."<br>";
}else{
Echo "There was a problem sending file ".$_FILES['userfiles']['name'][$x]."<br>";;
}
}
// close the FTP stream
Ftp_close($conn_id);
}
Else echo"File was not uploaded!<br>";
}
}
Echo "<br>";

}//end for loop

}
//That's all folks!
?>
and save that as upload.Php (please note casing is important)

No when you log in to your ftp make sure that you CHMOD the directory to 777, this should help,
