สอบถามเกี่ยวกับการinsert fileรูปภาพไปยังDatabaseกับFolderหน่อยครับ

if(isset($_POST['action']) && $_POST['action'] == "insert")
    {
        echo"<pre>",print_r($_FILES['profileImage']['name']), "</pre>";
        $uname = $_POST['uname'];
        $pword = $_POST['pword'];
        $fname = $_POST['fname'];
        $lname = $_POST['lname'];
        $phone = $_POST['phone'];
        $email = $_POST['email'];
        $position = $_POST['position'];
        $userlevel = $_POST['userlevel'];
        $profileImageName = time() . '_' . $_FILES['profileImage']['name'];

        $target = 'images/' . $profileImageName;

        move_uploaded_file($_FILES['profileImage']['tmp_name'], $target);

        $dbmember->insertmember($uname,$pword,$fname,$lname,$phone,$email,$position,$userlevel,$profileImageName);

    }

public function insertmember($uname,$pword,$fname,$lname,$phone,$email,$position,$userlevel,$profileImageName){
                                    $sql = "INSERT INTO user (Username,Password,Firstname,Lastname,Phone,Email,Position,Userlevel,profile_image) VALUES (:username,:password,:firstname,:lastname,:phone,:email,:position,:userlevel,'$profileImageName')";
                                    $stmt = $this->conn->prepare($sql);
                                    $stmt->execute(['username'=>$uname,'password'=>$pword,'firstname'=>$fname,'lastname'=>$lname,'phone'=>$phone,'email'=>$email,'position'=>$position,'userlevel'=>$userlevel]);
                                    return true;
                                    }
