As I will cover this Post with live Working example to develop jQuery Ajax PHP MySQLi Login Form System, so the Simple Ajax Login form with jQuery and PHP for this example is following below.
Step 1 : Create Ajax Login Form
signin_form.php
<!DOCTYPE html>
<html lang="en">
<head>

<body>
<div class="container">

<script src="https://code.jquery.com/jquery-3.2.1.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min.js"></script>
<script>
$(function()
{
$('#login').click(function(e){
let self = $(this);
e.preventDefault();
self.prop('disabled',true);
var data = $('#signin_form').serialize();
$.ajax({
url: '/signin.php',
type: "POST",
data: data,
}).done(function(res) {
res = JSON.parse(res);
if (res['status'])
{
location.href = "secure.php";
} else {
var loadErrMsg = '';
console.log(res.message);
$.each(res['message'],function(index,message) {
loadErrMsg += '<p>' + message+ '</p>';
});
$("#preview_err").html(loadErrMsg);
$("#preview_err").show();
self.prop('disabled',false);
}
}).fail(function() {
alert("responseError");
}).always(function(){
self.prop('disabled',false);
});
});
});
</script>
</body>
</html>
Step 2 : Database Detials
member table structure in your database
CREATE TABLE IF NOT EXISTS `members` ( `member_id` int(11) NOT NULL AUTO_INCREMENT, `member_fname` varchar(255) NOT NULL, `member_lname` varchar(255) NOT NULL, `email` varchar(255) NOT NULL, `password` varchar(255) NOT NULL, `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (`member_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=2; -- -- Dumping data for table `members` -- INSERT INTO `members` (`member_id`, `member_fname`, `member_lname`, `email`, `password`, `created_at`) VALUES (1, 'Jaydeep', 'PHP', '[email protected]', '$2y$10$8mVSGv/bIGgcvCik9825606241Ml3jqfiirtQG9909816257LG', '2019-10-12 18:09:10');
Step 3 : configuration in Database
Config.php
<?php
define('DB_SERVER', 'localhost');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', '[email protected]');
define('DB_DATABASE', 'atmiya25');
$db = new PDO('mysql:host='.DB_SERVER.';dbname='.DB_DATABASE, DB_USERNAME, DB_PASSWORD);
?>
signin.php
<?php
require_once('config.php');
$responseError = array();
$res = array();
if(empty($_POST['email']))
{
$responseError[] = "Member Email field is required";
}
if(empty($_POST['password']))
{
$responseError[] = "Member Password field is required";
}
if (!empty($_POST['email']) && !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$responseError[] = "Member Enter Valid Email address";
}
if(count($responseError)>0)
{
$results['message'] = $responseError;
$results['status'] = false;
echo json_encode($results);
exit;
}
$statement = $db->prepare("select * from members where email = :email" );
$statement->execute(array(':email' => $_POST['email']));
$row = $statement->fetchAll(PDO::FETCH_ASSOC);
if(count($row)>0) {
if(!password_verify($_POST['password'],$row[0]['password'])) {
$responseError[] = "Member Password is not valid";
$results['message'] = $responseError;
$results['status'] = false;
echo json_encode($results);
exit;
}
session_start();
$_SESSION['member_id'] = $row[0]['member_id'];
$results['redirect'] = "home.php";
$results['status'] = true;
echo json_encode($results);
exit;
} else {
$responseError[] = "Email does not match";
$results['message'] = $responseError;
$results['status'] = false;
echo json_encode($results);
exit;
}
secure.php
<?php
session_start();
if(empty($_SESSION['member_id'])){
header('location: signin_form.php');
} else {
echo 'Secure page!.';
echo '<a href="/signout.php">signout</a>';
}
signout.php
session_start();
session_destroy();
header('location: signin.php');
