if(isset($_POST['submit'])){

    $token="1234567890dsfdfssdfASASDF113454fdzsdfsdfsdfsdfsdf658696gfjgtkgjjkghxcgfgfdfzsdfsd0637745453638";
    $token= str_shuffle($token);
    $token= substr($token,0,30);
 
    $date=date('Y-m-d');
    $status="process";
 
    $id = unique_id();
 
    $name = $_POST['name'];
    $name = filter_var($name, FILTER_SANITIZE_STRING);
 
    $description = $_POST['description'];
    $description = filter_var($description, FILTER_SANITIZE_STRING);
 
    $number = $_POST['number'];
    $number = filter_var($number, FILTER_SANITIZE_STRING);
 
    $author = $_POST['author'];
    $author = filter_var($author, FILTER_SANITIZE_STRING);
 
    $cToken = $_POST['cToken'];
    $cToken = filter_var($cToken, FILTER_SANITIZE_STRING);
 
    $cName = $_POST['cName'];
    $cName = filter_var($cName, FILTER_SANITIZE_STRING);
 
    $thumb = $_FILES['thumb']['name'];
    $thumb = filter_var($thumb, FILTER_SANITIZE_STRING);
    $thumb_ext = pathinfo($thumb, PATHINFO_EXTENSION);
    $rename_thumb = unique_id().'.'.$thumb_ext;
    $thumb_size = $_FILES['thumb']['size'];
    $thumb_tmp_name = $_FILES['thumb']['tmp_name'];
    $thumb_folder = 'images/'.$rename_thumb;
 
    $video = $_FILES['video']['name'];
    $video = filter_var($video, FILTER_SANITIZE_STRING);
    $video_ext = pathinfo($video, PATHINFO_EXTENSION);
    $rename_video = unique_id().'.'.$video_ext;
    $video_tmp_name = $_FILES['video']['tmp_name'];
    $video_folder = 'images/'.$rename_video;
 
    if($thumb_size > 2000000){
       $message = '<h3 style="color:red"> Image size is too large!!</h3>!';
    }else{
       $add_playlist = "INSERT INTO course_content (token, name, description, video, image, number, author, course_token, course, date, status) 
       VALUES('$token', '$name', '$description', '$rename_video', '$rename_thumb', '$number', '$author', '$cToken', '$cName', '$date', '$status')";
       if(mysqli_query($con,$add_playlist)){
            move_uploaded_file($thumb_tmp_name, $thumb_folder);
            move_uploaded_file($video_tmp_name, $video_folder);
            $message = '<h3 style="color:green"> New course uploaded!!!</h3>';
       }else{
            $message = '<h3 style="color:red"> Something went wrong. Please try again</h3>';
       }
    }
