Easy Login Script Without Database

Easy login script without database

It's not an ideal solution but here's a quick and dirty example that shows how you could store login info in the PHP code:

<?php
session_start();

$userinfo = array(
                'user1'=>'password1',
                'user2'=>'password2'
                );

if(isset($_GET['logout'])) {
    $_SESSION['username'] = '';
    header('Location:  ' . $_SERVER['PHP_SELF']);
}

if(isset($_POST['username'])) {
    if($userinfo[$_POST['username']] == $_POST['password']) {
        $_SESSION['username'] = $_POST['username'];
    }else {
        //Invalid Login
    }
}
?>

    </head>
    <body>
        <?php if($_SESSION['username']): ?>
            <p>You are logged in as <?=$_SESSION['username']?></p>
            <p><a href="?logout=1">Logout</a></p>
        <?php endif; ?>
        <form name="login" action="" method="post">
            Username:  <input type="text" name="username" value="" /><br />
            Password:  <input type="password" name="password" value="" /><br />
            <input type="submit" name="submit" value="Submit" />
        </form>
    </body>
</html>

PHP login page without database

you can do this

after you post your form values to the server page

just use if conditions and pattern match(for email)

$password= test_input($_POST["password"]);
if(empty($password)){
$err[]='password Required';
}
if (!preg_match("/^(?=.*\d)(?=.*[A-Za-z])[0-9A-Za-z!@#$%]{8,12}$/",$password)) {
  $err[]= "Only letters and white space allowed"; 

}

 if (empty($_POST["email"])) {
    $err[]= "Email is required";
  } else {
    $email= test_input($_POST["email"]);
    // check if e-mail address is well-formed
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
      $err[]= "Invalid email format"; 
    }
  }

if(!empty($err)){
 //// echo "email or password error//
var_dump($err); 
}else{
///do your success
}

Best login management solution without database in PHP

There are other solutions like that, but I can't find nicer links right now:

http://webscripts.softpedia.com/script/Authentication/AuthMan-Free-42216.html
http://www.phpkode.com./scripts/item/passwdauth/
http://www.hotscripts.com/listing/htaccess-manager-lite/
http://www.hotscripts.com/listing/needlock-access-management-system/
http://www.hotscripts.com/listing/dirlock/ (Ooops. Too many hotscripts links. So just saying: not affiliated with that. :] And certainly not endorsing it!)

Anyway. These scripts store usernames and passwords into a .htpasswd file. This can be used independently from the PHP script. .htaccess and .htpasswd is common authentication scheme for Apache webservers. See this tutorial: http://www.javascriptkit.com/howto/htaccess3.shtml or the Apache manual: http://httpd.apache.org/docs/2.0/howto/auth.html

You could use the class itself for authentication, but it doesn't look very current. The login management tool might be useful to you. (But again: there are probably easier ones to find.)

Login form php without database - reloading

Something like this should do the job: (untested)

<?php 
session_start();
$username = $_POST['username'];
$password = $_POST['password'];

if ($username =='john' AND $password=='abc') {
    header("Location:/detalhes.php");
} elseif ($username!='john' OR $password!='abc'){
    $_SESSION['msg'] = "Wrong, try again.";     
    header("Location:http://localhost/index.php");
}
?>

log.php

<?
session_start();
<?php if(isset($_SESSION['msg']))
    echo $_SESSION['msg'];
    unset($_SESSION['msg']);
?>

Login Form use ReactJS (without database) with map()?

You can use .some() method.

doc: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/some

Something like this

var username = e.target.elements.username.value;
var password = e.target.elements.password.value;

if(users.some((elem) => elem.username === username && elem.password === password)) {
 // when authentication is valid
} else {
 // not a valid username / password
}
