php - Struggling with checking if logged in -
hi there i'm trying figure out how check if user logged in , if allow them come in page if not homecoming 'index.php'.
what i've done create duplicate pages of such 'index.php', 'index2.php', 'service.php' , 'service2.php' on , forth minor adjustments such no 'search bar'.
is still possible so? i'd 'check see if logged in' on pages '2' in them. such 'service2.php' or 'about2.php'
i've tried code
(keep in mind code not whole entire page)
if(check_login()) { echo 'you in!'; } else { header('location: login.php'); exit; } function check_login () { if(isset($_session['login'] && $_session['login'] != '') { homecoming true; } else { false; } } only used code on pages want displayed
thanks in advance ! :)
