Well, I want to leave a login system that after login is validated when it goes to the login form page it appears that it is logged in and not the login form: ex:

phpcode:

<?phpsession_start();require'init.php';?><html><head><metacharset="utf-8">
<title>x1</title>
<link rel="stylesheet" href="css/css.css">

<body>

<header>
<div id="logobuscar">

<div id="logo"><img src="images/logosecure.png" alt="SecureStore" height="120" width="120"></div>
<div id="buscar">   <?php
                $sessao = $_SESSION['pedido'];
                $consulta = $pdo->prepare("SELECT * FROM carrinho_temporario WHERE temporario_sessao =:ses");
                $consulta -> bindValue(':ses', $sessao);
                $consulta -> execute();
                $linhas = $consulta -> rowCount();
                ?>
                <p class="text-right "><a href="carrinho.php" class="color-white bgcolor-red font-text-light font-weight-heavy car_show">Carrinho(<?= $linhas ?>)</a></p><br>

Validation code:

$users = $stmt->fetchAll(PDO::FETCH_ASSOC);

if (count($users) <= 0)
{
    echo "login ou senha incorretos";
    exit;

// pega o primeiro usuário
$user = $users[0];

session_start();

Just check if you are not logged in to submit the form

<?php
if ($_SESSION['logged_in'] != true){
?>


       <form action="login.php" method="post">
        <label for="email">Email: </label>
        <br>
        <input type="text" name="email" id="email">

        <br><br>

        <label for="password">Senha: </label>
        <br>
        <input type="password" name="password" id="password">

        <br><br>

        <input type="submit" value="Entrar">
    </form>
</div>
<?php
}
?>

other way

create a session at login $_SESSION['esconder'] = "display: none;";

and in the form's form tag

<form action="login.php" method="post" style="<?php echo $_SESSION['esconder'] ?>">

You should do this if the login is valid

addendum:

<?php
if ($_SESSION['logged_in'] != true){

    echo '<a href="logar.php"><li>Login</li></a>';

}else{

    echo $_SESSION['user_name'];
}
?>
