PHP AJAX重定向。 [帮帮我]

Question

I have a form that works in a modal way for registration / login. The part of the register is working normally. But the login part has a redirect problem ...

I am using this code below for AJAX. I have done a lot of research on everything I read about windows.location, but I do not know how to do it exactly.

AJAX:

 function logar(){

    $.ajax({
        method: "post",
        url: "validalogin.php",
        data: $("#login-form").serialize(),
    success: function(data){

               alert(data);
    }

});
}

PHP: I make the checks that I think necessary before and after I try to create a session through a result in the bank / data that the user typed ...

if ($result >1) {
    session_name('nacional');
    session_start();
    $_SESSION['cpf']=$cpf;
    $_SESSION['senha']=$senha;


    header("Location: my_folder/index.php");

}

• NOTE: The header tag is not targeting. Do I have to do something the way the server returns an "ok" for ajax and it changes the targeting? If so how to proceed?

Thanks for listening.

You should send a JSON response to your JavaScript instead of returning a header. The header redirects behind the scenes. Do something like this in your PHP:

return json_encode(['success' => true]);

Then, catch it in your success method of AJAX. You also need to tell your AJAX to expect JSON. Put that after your method and url parameters, like so:

function logar() {
    $.ajax({
        method: "post",
        url: "validalogin.php",
        data: $("#login-form").serialize(),
        dataType: 'json'
    })
    .success(function(data){
        if (data.success == true) {
            alert(data);
            window.location.href = "folder/index.php";
        }
    });
}
