Create special PHP link

[bgbs]

I need to create a button link which determines where to go depending whether the user is signed in or not.

So if he is not signed in, it takes him to registration, if he is, it takes him to a payment page.  Is it possible to do something like that?

 

[dropfaith]

use a php session and if the session is set  send user to payment if session unset send users to register

edit that up a bit should work

<?php
session_start( ); 
if(!isset($_SESSION["username"])){
header('Location: /register.php');
}
else
{
header('Location: /payment.php');
}
?>

Entirely possible:

 

Example:

 

<?php
session_start();

if (isset($_SESSION['loggedin']) && $_SESSION['loggedin']) {
    header('Location: registration.php');
}else {
    header('Location: payment.php');
}
?>

wow, this looks complicated.

Thanks for your help guys

 

But where do I stick this code?

 

Here is the button link.  Button is generated by CSS.

<div class="signuplink"><a href="register.php">To become a Premium Member  - SIGN UP NOW </a>  </div>

 

 

So I erase the href and put in the php code in there?

at the top of every page i guess. Remember session_start(); my appear before outputting any html tags.

<?php
session_start( ); 
if(!isset($_SESSION["username"])){
echo '<div class="signuplink"><a href="register.php">To become a Premium Member  - SIGN UP NOW</a>  </div>'; 
}
else
{
echo '<div class="paymentlink"><a href="payment.php">Continue to checkout</a>  </div>'; 
}
?>

 

try that

Ok, I tried that, but I get this error

 

 

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/wass/public_html/pricing.php:16) in /home/wass/public_html/inc.pricing.php on line 101

session_start() has to be called before any code is displayed to the browser, once that happens you cannot use that function or you will get the error. Move session_start to line one, like in the example above.

For some reason its still not working. after I placed the code at the top it gives me this error now

 

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/wass/public_html/pricing.php:15) in /home/wass/public_html/inc.pricing.php on line 2

 

Warning: Cannot modify header information - headers already sent by (output started at /home/wass/public_html/pricing.php:15) in /home/wasc/public_html/inc.pricing.php on line 4

[dropfaith]

that error has been explained there cannot be anything whitespace included above the session start
