This code redirects to login page instead of staying in same home page.

Question

I want my website to be accessed either by session or cookie. But after writing this code, the page needs both condition to be true instead of one. What's wrong here?

<?php
    if(((isset($_SESSION['SUCCESS']) && $_SESSION['SUCCESS'] != "") || 
    (isset($_COOKIE['is_logged_in']) && $_COOKIE['is_logged_in'] != "")) 
     == false){
        $_SESSION['ERROR'] = "Please login first";
        header('location: login.php'); 
    }

?>

Answer 1

No need to write == false . Try with removing it

if((isset($_SESSION['SUCCESS']) && $_SESSION['SUCCESS'] != "") || 
(isset($_COOKIE['is_logged_in']) && $_COOKIE['is_logged_in'] != "")
 ){
    $_SESSION['ERROR'] = "Please login first";
    header('location: login.php'); 
}

Answer 2

if(isset($_COOKIE['is_logged_in']) && $_COOKIE['is_logged_in'] != ""){
    if(!isset($_SESSION['SUCCESS'])){
        $_SESSION['SUCCESS'] = true;//or whatever you want
    }
}

And then check session

if(!isset($_SESSION['SUCCESS']) || $_SESSION['SUCCESS'] == ""){
    $_SESSION['ERROR'] = "Please login first";
    header('location: login.php');
}else{
    //move to home page
}
