PHP + Ajax Login

whole issue is in jquery use this instead

$(document).ready(function() {  $('#loginform').submit(function(e) {    e.preventDefault();    $.ajax({       type: "POST",       url: '/class/login.php',       data: $(this).serialize(),       success: function(data)       {          if (data === 'Login') {            window.location = '/user-page.php';          }          else {            alert('Invalid Credentials');          }       }   }); });});

 $user = new User(array("username" => $_POST['username'], "password" => $_POST['password'])); $user->Login();

Put the code above into an login.php controller file (including your users class). Or write a general controller that handles the requests.

$(document).ready(function(){ $("#submit").click(function(){    var email = $("#email").val();    var password = $("#password").val(); if(email.length == "" || password.length == ""){    $("#message").html("please fill out this field first").fadeIn();    $("#message").addClass("error");     return false;}else{    $.ajax({      type : 'POST',      url  : 'redirect.php',      data : {email:email,password:password},      success : function(feedback){         $("#text").html(feedback);       }      });   }});$(".email_error_text").hide();$(".password_error_text").hide();var error_email = false;var error_password = false;$("#email").focusout(function(){  check_email();});$("#password").focusout(function(){  check_password();});function check_email(){    $("#message").hide();var pattern = new RegExp(/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/);if(pattern.test($("#email").val())){     $(".email_error_text").hide();  }else{     $(".email_error_text").html("Invalid email address");     $(".email_error_text").show().addClass("error");     error_email = true;  }}function check_password(){    $("#message").hide();var password_length = $("#password").val().length;if(password_length < 8 ){     $(".password_error_text").html("Should be at least 8 characters");     $(".password_error_text").show().addClass("error");     error_password = true;  }else{     $(".password_error_text").hide();  }}

});
