Connect to FTP via upload script

[biwerw]

I will try to explain as best I can what I would like to do:

 

I have a php script that uploads to a directory on the webserver my site is hosted on and that works. However my client would like to be able to upload to their separate ftp server from their website.

 

So my question is: Is it possible to use php with a html form that will login, connect and upload the file to the desired directory on a different server than where the website is hosted?

 

I know you can just type the ftp address into the browser and login / upload but I would like to use this "portal" designed site I have created.

 

Thanks

Yes it is possible. Read up on the ftp functions available in PHP.

Thanks for the info on php and ftp.

 

I'm still pretty new to PHP, is there a script i can refer to and/or pull certain elements from?

 

Thanks

The great thing about the PHP documentation that there is always at least one example given.

So just click the links of the functions with the most logical names.

 

Or.. google knows all

I was able to get the following code to work great. What would I need to adjust to get the confirmation to be displayed on the page with the form? Instead of a separate white page? I would also like to add an animated .gif progress bar that is only visible while the file is being uploaded.

 

<?
//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="/LGL-up"; //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!
?>

 

Here is my html form code:

 

<form name="fileup" method="post" enctype="multipart/form-data" action="upload-lgl.php">
                    
                    <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>

 

Thanks!
