Display info of a logged_in user

[mtran]

Hi,
Again with login page. I have:

1/ login: an html form [with username/password fields]
2/ login_check.php: to validate the username/password against db, if correct then setcookie, and go to 3/ member_only.php.:
How do I make a simple greeting in 3/, say: Welcome <?php print $username; ?>!

All I know so far is in 2/ I can set:
$username=$_POST["username"];
and refer to $username whenever I want to within 2.

But in 3/ I don't know how, because there's no $_POST...

Because I don't know to display that "Welcome...," I don't know how to show/display all info [query from db] related to that user either.
Thanks very much for help!

Get the info from that cookie you set.
Although I'd advise using sessions, not cookies, here.

Stumbling and not yet know how to do:

If in 2/ I set:

setcookie('log',$username,time()+3600);

and in 3/ I check cookie:


<?php
require ('config.php');
if(!isset($_COOKIE['log'])){
Header('Location:login.php');}
?>


How do I say welcome [username]? Or Your email is..., your phone is....
Thanks

Welcome, <?php echo($_COOKIE['log']); ?>!
