It seems i have a syntax error in this part. It's is driving me mad. Maybe the insert syntax is not correct ?

```
public static function saveUser($form)
{
  $connexion = new PDO("mysql:host=localhost;dbname=cdiscountdb", 'root', 'root'); // connexion à la BDD
  $connexion->setAttribute  (PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
  $connexion->exec("INSERT INTO ope_tartine_nl(first_name,last_name,email,created_date,updated_date) VALUES ($form['name'],$form['lastname'],$form['email'],date("Y-m-d H:i:s"),date("Y-m-d H:i:s"))");

}

```

Thanks in advance for your help
