Ron's Guide

Please post questions or comments about this tutorial below.

Could I do something like

if($_COOKIE[\'blah\']){
echo \'logged in\';
}

to check if a cookie exists?

If you want to check if the cookie exists use the isset function. Like this:

if(isset($_COOKIE[\'mycookie\'])) {
echo \"The cookie exists!\";
}

Well play\'ed arround with this tut, and i\'m now using it on my site for my friendNet system to check login cookies...

Really nice Ron

Another great tutorial, Ron. It was about time you made another tutorial

Excellent, Glad it was helpful Teco.

Thank you Bfr

Can i use form variables as perameters for my cookie. like to log a person in directly upon registration?

Yes, you could do that.

allright., how?

well, you could do something like:

<?php

setcookie('username', $_POST['username']);

?>

That would set the cookie "username" to the value of the username field passed through a post form.
