PHP, FTP, file upload

Question

I have a form on my page that allows me to add new articles.There are two fields for photo upload (thumbnail and main photo) unfortunately I have a problem with uploading photos on FTP.

I get the error: ftp_put (): This is a private system - No anonymous login [file]

$thumbnail_img = $_FILES['a_thumbnail']['name'];
$temp_name1 = $_FILES['a_thumbnail']['tmp_name'];

$thumbnail_img = $_FILES['a_image']['name'];
$temp_name2 = $_FILES['a_image']['tmp_name'];

move_uploaded_file($temp_name1,"a_thumbnails/$thumbnail_img");
move_uploaded_file($temp_name2,"a_images/$thumbnail_img");


$destination_file1 = "/www/a_thumbnails/";
$destination_file2 = "/www/a_images/";


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

// login with username and password
$login_result = ftp_login($conn_id, $ftgt_user_name, $ftgt_user_pass);

ftp_pasv($conn_id, true);

// upload the file
$upload1 = ftp_put($conn_id, $destination_file1, $temp_name1, FTP_BINARY);
$upload2 = ftp_put($conn_id, $destination_file2, $temp_name2, FTP_BINARY);

ftp_close($conn_id);

form:

<form method="post" class="form-horizontal" enctype="multipart/form-data" action="upload.php">
    <div class = row>
        <div class="col-6">
            <div class="form-group" style="padding-left: 50px; text-align: left">

Answer 1

The message stated that your FTP server requires user login. So you must have a proper ftp_login() on the connection before putting files there. And your login information is probably incorrect.

Try to test the login result before proceeding to upload. Like this:

$thumbnail_img = $_FILES['a_thumbnail']['name'];
$temp_name1 = $_FILES['a_thumbnail']['tmp_name'];

$thumbnail_img = $_FILES['a_image']['name'];
$temp_name2 = $_FILES['a_image']['tmp_name'];

move_uploaded_file($temp_name1,"a_thumbnails/$thumbnail_img");
move_uploaded_file($temp_name2,"a_images/$thumbnail_img");


$destination_file1 = "/www/a_thumbnails/";
$destination_file2 = "/www/a_images/";


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

// login with username and password
if (!ftp_login($conn_id, $ftgt_user_name, $ftgt_user_pass)) {
    // You'd probably want better error handling here
    exit('FTP Login Failed');
}

ftp_pasv($conn_id, true);

// upload the file
$upload1 = ftp_put($conn_id, $destination_file1, $temp_name1, FTP_BINARY);
$upload2 = ftp_put($conn_id, $destination_file2, $temp_name2, FTP_BINARY);

ftp_close($conn_id);
