正确验证请求[关闭]

Question

I think I miss something about the verification of my PHP request. I'm actually doing $result = $req->fetch(); but result always return false for some reason.

$bdd = new PDO($conStr,$user,$pass);
$req = $bdd->prepare('INSERT INTO users(login, password, dateregister) VALUES(?, ?, NOW())');
$req->execute(array($loginR,$passwordR));

$result = $req->fetch();

Answer 1

Check the return value of execute function for success/failure message

$res = $req->execute(array($login_fieldR,$password_fieldR));
   if (!$res )
    {
        echo '<p id="popup_text">Problem..</p>';
    }
    else
    {
        echo '<p id="popup_text">You are registered ! You can logged in now';
    }
