get username after login

[adi123]

I have created a simple login system but need help getting the username after login is successfull.

 

The login page

<?php

session_start();

require_once 'classes/Membership.php';

$membership = new Membership();

 

// If the user clicks the "Log Out" link on the index page.

if(isset($_GET['status']) && $_GET['status'] == 'loggedout') {

$membership->log_User_Out();

}

 

// Did the user enter a password/username and click submit?

if($_POST && !empty($_POST['username']) && !empty($_POST['pwd'])) {

$response = $membership->validate_User($_POST['username'], $_POST['pwd']);

}

?>

      <div id="login">

        <form method="post" action="">

          <table width="200" border="0" align="center">

            <tr>

              <th scope="col">Username:</th>

              <th scope="col"><input type="text" name="username" /></th>

            </tr>

            <tr>

              <td>Password:</td>

              <td><input type="password" name="pwd" /></td>

            </tr>

            <tr>

              <td colspan="2"><input type="submit" id="submit" value="Login" name="submit" /></td>

            </tr>

          </table>

          <p> </p>

          <p>

            <?php if(isset($response)) echo "<h4 class='alert'>" . $response . "</h4>"; ?>

          </p>

    </form>

      </div>

 

Membership.php file

 

<?php

 

require 'Mysql.php';

 

class Membership {

 

function validate_user($un, $pwd) {

$mysql = New Mysql();

$ensure_credentials = $mysql->verify_Username_and_Pass($un, md5($pwd));

 

if($ensure_credentials) {

$_SESSION['status'] = 'authorized';

header("location: myaccount.php");

} else return "Please enter a correct username and password";

 

}

 

function log_User_Out() {

if(isset($_SESSION['status'])) {

unset($_SESSION['status']);

 

if(isset($_COOKIE[session_name()]))

setcookie(session_name(), '', time() - 1000);

session_destroy();

}

}

 

function confirm_Member() {

session_start();

if($_SESSION['status'] !='authorized') header("location: login.php");

}

}

 

 

myaccount page

 

<?php

 

require_once 'classes/Membership.php';

$membership = New Membership();

 

$membership->confirm_Member();

 

?>

 

<p>Welcome <?= $_SESSION['status'] ?></p

I'm assuming this function you're calling returns true or false depending if login credentials correct / incorrect.

You should set the username into the session if this login attempt is successful

 

//in your first file

// Did the user enter a password/username and click submit?
if($_POST && !empty($_POST['username']) && !empty($_POST['pwd'])) {
   $response = $membership->validate_User($_POST['username'], $_POST['pwd']);

if ($response == true)
{
$_SESSION['username'] = $_POST['username'];
}
}

that code does not work.

[adi123]

when the user logs in it prints welcome authorized rather than the username.

did you...

1. try echoing out the username?

2 store the username to a session variable?
