Hi ive been trying to get this login to work but it doesn't seem to work please help:

 

login.php:

<?php

 

//ob

ob_start();

 

//session

session_start();

 

if (isset($_SESSION['username']))

{

header("Location: main.php");

exit();

}

 

//connect

$error = 'Could not connect to the database';

mysql_connect('localhost','************','***************') or die($error);

if ($_POST['login'])

 

this is incorrect your submit button is labeled signup not login,

 

you should check for form submission like this

 

if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['username'])) {

 

because sometimes a user will hit the enter key and submit your form, doing this in ie will not send the value of your submit button as it was not clicked.
