Upload script

talkster5

Hi,
I am trying to make a simple upload script to my site and its all working fine how it is at the moment. However the one thing I want to do is generate a name so like image_1, image_2 and so on. My current code is below if it helps

// FTP details
$conn_id = "ftp_upload";
$ftp_server = "ftp.deadlyhosting.com"; 
$ftp_username = "uploader@deadlyhosting.com"; 
$ftp_password = "***";
//File upload details
$source_file = "$file";
$destination_file = "$name"; 

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

// login with username and password
$login_result = ftp_login($conn_id, $ftp_username, $ftp_password); 

// check connection
if ((!$conn_id) || (!$login_result)) { 
        echo "FTP connection has failed!";
        echo "Attempted to connect to $ftp_server for user $ftp_username"; 
        exit; 
    } else {
        echo "Connected to $ftp_server, for user $ftp_username";
    }

//Select Directory
echo "Current directory : ", ftp_pwd($conn_id), "\n";

if (@ftp_chdir($conn_id, "/")) {
    echo "Current directory is now : ", ftp_pwd($conn_id), "\n";
} else { 
    echo "Couldn't change directory\n";
}

// upload the file
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); 

// check upload status
if (!$upload) { 
        echo "FTP upload has failed!";
    } else {
        echo "Uploaded $file to $ftp_server as $destination_file";
    }

// close the FTP stream 
ftp_close($conn_id);

Do you want to generate a filename taking into account the other files in the folder?

Why not use the filename of the file uploaded, and check for existing files with the same name.

easy to do either way.

Just a quick note, are you adding information to a database?

If so you could call the file the record id for the database record.

example:

database record 1
filname should then be filename_1

you can get the database id after you have added it to the database and then process the file.

How can I make it do this please?

also no I am not storing it in a database.

Well, here goes...

Way 1:

use something like this to count the files in the folder, and then you have a filename.

$filecounter = 0;
$folder = opendir("files");
while($file = readdir($folder)) {

$filecounter = $filecounter + 1;
}

}

so if there are 10 files in the folder, the filename of the newly uploaded file would be filename_11

Way 2:

This is really to check to see if the file name is already taken or not. So...

$filename = '/path/to/foo.txt';

if (file_exists($filename)) {
print "The file $filename exists";
} else {
print "The file $filename does not exist";
}

should get you a result, on which your script can save, or rename and save the file.

How's that?

Hope this helps...

🙂

Actually thats not quite what I meant.

If i wanted to keep the filename of what I am uploading how would I go abouts doing that as at the moment I am having to type in what I want the file to be called.

If you are allready using ftp connenction, use that to read the files also. No need to use readdir.

If you want to use the same name as the uploaded filename, use $_FILES['varname']['name'].

So if you have a form and fileinput like this:

<form action="upload.php" enctype="multipart/form-data" method="post">
<input type="file" name="myfile">
...

..Then in your upload script use:

// upload the file 
$source_file=$_FILES['myfile']['tmp_name'];
$destination_file=$_FILES['myfile']['name'];
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);

Thanks, I will test that out now.
