Я пытаюсь создать форму для входа пользователей на мою веб-страницу, используя mysql db.
Моя страница index.php имеет форму, которая отправляет сообщения doLogin.php, который проверяет пользователя / пароль из базы данных mysql. Как только пользователь будет подтвержден, я хотел бы показать имя пользователя в div, чтобы показать, что он вошел в систему.
index.php
1010 * JQuery *
$document.ready(function() {
$("#login_b").click(function() {
var action = $("#form1").attr('action');
var form_data = {
username: $("#username").val(),
password: $("#password").val(),
is_ajax: 1
};
$.ajax({
type: "POST",
url: action,
data: form_data,
success: function(response)
{
if(response == 'success')
alert( username + "Te logeaste correctamente","alert window");
document.location.href='index_spa.php';
$("#user_data").html( username + " online");
if(response == 'empty')
alert("No hay datos para validar","alert window");
$("#user_data").html("Campos vacios");
document.location.href='index_spa.php'
if(response == 'incorrect')
alert("Error en los datos introducidos","alert window");
$("#user_data").html("Datos incorrectos");
document.location.href='index_spa.php'
if(response == 'inactive')
alert("Cuenta no activada","alert window");
$("#user_data").html("La cuenta no está activada");
document.location.href='index_spa.php'
}
});
return false;
});
});
