[PHP]Session redirection

Joser · Aug 7, 2009

Okay heres what I've come up with.
The index.php is below and is just a picture and login form.
So if they already logged in I want it to redirect to home.php.

PHP:

<html>
<title>~ Homepage ~</title>
<center>

<?php

session_start();

$_SESSION['username']=$username;

if(isset($_SESSION['username']
{
	//redirect to home.php
}
else
{ ?>
<img src="images/jose.jpg"></img>
<h1>Welcome.</h1>
<h2>Please Login :)</h2>
<br /> <br /> <br />

<form action="login.php" method="POST">
Username: <input type='text' name='username'> <br /><br />
Password: <input type='password' name='password'> <br /><br />
<input type='submit' value='Login!'>
</form>
<br>
<a href="register.php">Don't Have an Account? Register now!</a>
<?php } ?>
</center>
</html>

Any help would be great

SOmething like this. Session start must always be before you output any HTML or send any other headers or something.

If i'm right this should work (not sure, had to do it quickly)

Code:

<?php 
session_start(); 

$_SESSION['username']=$username; 

if(isset($_SESSION['username'] 
{ 
    header('Location: home.php');
} 
else 
{ ?> 

<html> 
<title>~ Homepage ~</title> 
<center> 
<img src="images/jose.jpg"></img> 
<h1>Welcome.</h1> 
<h2>Please Login :)</h2> 
<br /> <br /> <br /> 

<form action="login.php" method="POST"> 
Username: <input type='text' name='username'> <br /><br /> 
Password: <input type='password' name='password'> <br /><br /> 
<input type='submit' value='Login!'> 
</form> 
<br> 
<a href="register.php">Don't Have an Account? Register now!</a> 
</center> 
</html>
<?php } ?>

You only did the half thing..

PHP:

<?php 
session_start(); 

$_SESSION['username'] = $username; 

if(isset($_SESSION['username']))
{ 
    header('Location: home.php');
} 
else 
{
?> 

<html> 
<title>~ Homepage ~</title> 
<center> 
<img src="images/jose.jpg"></img> 
<h1>Welcome.</h1> 
<h2>Please Login :)</h2> 
<br /> <br /> <br /> 

<form action="login.php" method="POST"> 
Username: <input type='text' name='username'> <br /><br /> 
Password: <input type='password' name='password'> <br /><br /> 
<input type='submit' value='Login!'> 
</form> 
<br> 
<a href="register.php">Don't Have an Account? Register now!</a> 
</center> 
</html>
<?php } ?>

Headers / Session_start must always become before ANY output.
