Answer 1

It’s simple, you just need to include this line in php:

<?php header('Location:pedidos.php');?>

I hope I’ve helped!

Answer 2

You can do it like this:

$query1 = mysqli_num_rows(mysqli_query("SELECT * FROM USUARIO WHERE USUARIO = '$user' AND SENHA = '$pwd'"));
        if($query1 == 1){
            header("Location: pedidos.php");
        }else{
            echo "<script>alert('Usuário e senha não correspondem.'); history.back();</script>";
        }

or

$query1 = mysqli_num_rows(mysqli_query("SELECT * FROM USUARIO WHERE USUARIO = '$user' AND SENHA = '$pwd'"));
        if($query1 == 1){
            echo "<script>location.href='pedidos.php'</script>";
        }else{
            echo "<script>alert('Usuário e senha não correspondem.'); history.back();</script>";
        }

I hope it helps
