FTP Upload with PHP for Beginners

Posted on
To upload a file to ftp you need a html form where you can insert the ftp details, like the ones described above:

server - is the server on which he wanna upload the file.
username - is the user for which he makes the connection to ftp server.
password - is the user password for ftp username.
path to server - is the path on the ftp server which he wanna upload his file.
user file - is the file of the you wanna upload to ftp server.

Hint: If you want to offer to your website members a form where he will upload his file, you should take the ftp server details and path, from a config file. Here we made a complete example how to upload through ftp putting all the details.

We will have a POST form and an enctype of multipart/form-data because we have a file on our form. The user form that the user will insert info is like that:
<form action="get_upload.php" method="POST" enctype="multipart/form-data"> <table align="center"> <tr> <td align="right">Current server:</td> <td><input size="50" type="text" name="server" value=""></td> </tr> <tr> <td align="right">Username:</td> <td><input size="50" type="text" name="user" value=""> </td> </tr> <tr> <td align="right">Password:</td> <td><input size="50" type="text" name="password" value="" ></td> </tr> <tr> <td align="right">Path on the Server:</td> <td><input size="50" type="text" name="pathserver" ></td> </tr> <tr> <td align="right">Select File to Upload:</td> <td><input name="userfile" type="file" size="50"></td> </tr> </table> <table align="center"> <tr> <td align="center"><input type="submit" name="submit"></td> </tr> </table> </form>

When the user submits the form, we should get all the details that he inputed and then upload the file to the ftp server.
// the file name that should be uploaded $filep = $_FILES['userfile']['tmp_name']; $ftp_server = $_POST['server']; $ftp_user_name = $_POST['user']; $ftp_user_pass = $_POST['password']; $paths = $_POST['pathserver']; //the name of the file on the server after you upload the file $name = $_FILES['userfile']['name'];

To upload the file , first we should establish a connection to the ftp server using ftp_connect and specifing as a parameter the ftp servver. This function return a connection id.
$con_id = ftp_connect($ftp_server);

After connecting to server we should login using the function ftp_login passing three parameters: connection id, ftp user, ftp user password and checking if the login was sucessfull.
// 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!"; echo "Attempted to connect to $ftp_server for user: $ftp_user_name"; exit; } else { echo "Connected to $ftp_server, for user: $ftp_user_name"; }

After loging in we can upload the file to the server and after that check if the file was uploaded correctly:
// upload the file $upload = ftp_put($conn_id, 'public_html/'.$paths.'/'.$name, $filep, FTP_BINARY); // check upload status if (!$upload) { echo "Error: FTP upload has failed!"; } else { echo "Good: Uploaded $name to $ftp_server"; }

For close the ftp connection we using ftp_close passing the connection id:
ftp_close($conn_id);

For uploading big files you should set the time limit of the server in order not to finish the script while it's uploading:
set_time_limit(300);
