    if($_SESSION['user']==''){
        header("Location:login.php");
    }else{
        $dbh=new PDO('mysql:dbname=mydb;host=127.0.0.1', 'myusername', 'mypassword');


    $sql=$dbh->prepare("SELECT * FROM users WHERE id=?");
    $sql->execute(array($_SESSION['user']));
    while($r=$sql->fetch()){

    $username=$r['username'];  <-im not sure if this is correct.
    $ime=$_POST['ime'];
    $priimek=$_POST['priimek'];
    $email=$_POST['email'];
    $izob=$_POST['izob'];
    $izk=$_POST['izk'];

        $sql = "INSERT INTO profil (ime, priimek, email, izob, izk, prib, opis) VALUES( `username`,`ime` , `priimek ` , `email` , `izob` , `izk` , `prib` , `opis`)";

        try {
            $dbh->exec($sql);
            echo " created successfully";
        } catch(PDOException $e) {
            echo $sql . "<br>" . $e->getMessage();
        }
    }

    $conn = null;

id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
        username VARCHAR(10),
        ime VARCHAR(10) NOT NULL,

        izk VARCHAR(10),
        prib VARCHAR(10),
        opis VARCHAR(100),
);

Answer 1

Two problems:

First, you only specified 7 column names in the insert list, but you gave 8 values. Most importantly, the column name you failed to specify was the username column, which is what you are asking about. Second, you should be using the actual PHP variables in the insert, not the column names escaped in backticks. Try the following:

$sql = "INSERT INTO profil (username, ime, priimek, email, izob, izk, prib, opis) ";
$sql = $sql . "VALUES(".$username.", ".$ime.", ".$priimek$.", ".$email.", ".$izob.", ".$izk.", ".$prib.", ".$opis.")";

Answer 2

remove username to your values and add backticks to insert .

it should be like this:

$sql = "INSERT INTO profil (`ime`, `priimek`, `email`, `izob`, `izk`, ``prib, `opis`) VALUES(`ime` , `priimek ` , `email` , `izob` , `izk` , `prib` , `opis`)";
