Redirected too many times

[xkevin]

I am experimenting/ trying to make a file named sso.php in the root folder. And include(require_once) this file on index.php so that when the website loads, the sso.php codes will run as well. But when I entered on the forum, it says  forum.com redirected you too many times . Some code in sso are:

define('IN_MYBB', 1);

require_once './global.php'; 

while (some code here) {
		if (user email is existing){
                    
                    Force user to login!

                    header( "Location: index.php" )
                    header( "Content-Length: 0" );
  	            exit;

                 else{

                header( "Location: member.php?register" ); 
                exit;
                 } 
}

member.php?register => should be member.php?action=register

member.php?register => should be member.php?action=register

sorry about that, changed it but still no work.

I think whenever I load the index.php file (which i require_once the sso.php file) it will call the sso file then call the index file again.. Its redirect looping.

You have no checks for the current page.

$result = $db->query("SELECT * FROM ".TABLE_PREFIX."users");
while ($row = $db->fetch_array($result)) {

	$myybbuser_email = $row['email'];
	$name = $row['username'];
	$the_email = '[email protected]';

		if ($myybbuser_email == $the_email){
			
			$query = $db->simple_select("users", "uid,username,password,salt,loginkey,email,usergroup", "username='$name'", array('limit' => 1));
			$user = $db->fetch_array($query);
		
			my_setcookie('loginattempts', 1);

       		$db->delete_query("sessions", "ip='".$db->escape_string($session->ipaddress)."' AND sid != '".$session->sid."'");
       		
			$newsession = array(
            	"uid" => $user['uid'],
        	);

			$db->update_query("sessions", $newsession, "sid='".$session->sid."'");
			
			$db->update_query("users", array("loginattempts" => 1), "uid='{$user['uid']}'");
			
			// Temporarily set the cookie remember option for the login cookies
			$mybb->user['remember'] = $user['remember'];
		
			my_setcookie("mybbuser", $user['uid']."_".$user['loginkey'], null, true);
			my_setcookie("sid", $session->sid, -1, true);
		
			$plugins->run_hooks("member_do_login_end");
			
		
    		header( "Location: index.php" ); 
     		header( "Content-Length: 0" );
			exit; 

 	 	}
		else{
			
		header( "Location: member.php?action=register" ) ; 
    		header ("Content-Length: 0");
			exit;
	 	}
}

This is my code for sso.php file. I required in once in my index.php

Okay, so, what if they are already in index.php? You're just redirecting them back to index.php and it makes a loop. You need to check if the page they are already on is index.php, if it isn't, then redirect them. If it is, don't redirect them or redirect them elsewhere.

if(defined('THIS_SCRIPT') && THIS_SCRIPT == 'index.php')
{
	//do not redirect
} else {
	// redirect
