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="upload.php" method="POST" enctype="multipart/form-data"> <table align="center"> <tr> <td align="right"> 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 your 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" value="Upload image" /> </td> </tr> </table> </form>
Now, 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 $ftp_server=$_POST['server']; //ftp user name $ftp_user_name=$_POST['user']; //ftp username password $ftp_user_pass=$_POST['password']; //path to the folder on which you wanna upload the file $paths=$_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 "FTP upload has failed!";
} else {
echo "Uploaded $name to $ftp_server ";
}
In the end we should close the ftp connection using ftp_close passing the connection id:
ftp_close($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);
Here is the complete code:
<?
if(!isset($_POST["submit"])){?> <form action="upload.php" method="POST" enctype="multipart/form-data">
<table align="center">
<tr>
<td align="right">
Server:
</td>
<td>
<input size="50" type="text" name="server" value="">
</td>
</tr>
<tr>
<td align="right">

<input size="50" type="text" name="user" value="">
</td>
</tr>
<tr>
<td align="right">

<td>
<input size="50" type="text" name="password" value="" >
</td>
</tr>
<tr>
<td align="right">
Path on the server:

<input size="50" type="text" name="pathserver" >
</td>
</tr>
<tr>
<td align="right">
Select your file to upload:

<td>
<input name="userfile" type="file" size="50">
</td>
</tr>
</table>
<table align="center">
<tr>
<td align="center">
<input type="submit" name="submit" value="Upload image" />
</td>
</tr> </table>
</form>
<?}
else
{ set_time_limit(300);//for setting $paths=$_POST['pathserver']; $filep=$_FILES['userfile']['tmp_name']; $ftp_server=$_POST['server']; $ftp_user_name=$_POST['user']; $ftp_user_pass=$_POST['password']; $name=$_FILES['userfile']['name']; // set up a connection to ftp server
$conn_id = ftp_connect($ftp_server); // login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // check connection and login result
if ((!$conn_id) || (!$login_result)) {
echo "FTP connection has encountered an error!";
echo "Attempted to connect to $ftp_server for user $ftp_user_name....";
exit;
} else {
echo "Connected to $ftp_server, for user $ftp_user_name".".....";
} // upload the file to the path specified
$upload = ftp_put($conn_id, $paths.'/'.$name, $filep, FTP_BINARY); // check the upload status
if (!$upload) {
echo "FTP upload has encountered an error!";
} else {
echo "Uploaded file with name $name to $ftp_server ";
} // close the FTP connection
ftp_close($conn_id); }
