PHP code to show if a user is logged in or not.

[bostonro]

Hi all,

Yet again another question, currently on my website (www.bostonrowingclub.x10.bx) I have the Pro Login software (script(s)) installed, I am wondering how I can show weather or not a user is logged in or not on all of my pages... I have changed most of them to .PHP

Thanks for your support,

BostonRo

Are you wanting your users to see if they are logged in, or are you wanting to see which users are logged in?

If the former, you could set a cookie and check on each page if the cookie is set then run your code.
Something like this:

<?php
if(isset($_COOKIE['login_details']))
{
//code here
}
else
{
//ask user to sign in
}
?>

If the latter, you would need to use a database table or flat file. Flat file would be easier on resources, but it would be recommended not to store any identifying information in it, i.e. names. When a user logs in, it sets the database or file accordingly. When a user logs out, it removes that user from the database or file.
