Redirect to original page after login

[TheEddy]

I want people to login and then be redirected back to the page from where they came from.  I was thinking that maybe I would have to use $_GET for 3 pages but I don't know if there is any easier way.

You could use $_SERVER['HTTP_REFERER'], or use sessions to store the previous page URI, then re-direct to that after login.

How does one use the HTTP_REFERER method?

[sbsads]

You should echo the $_SERVER['HTTP_REFERER'] variable to see the exact content of the string, but after you process your form, your VERY FIRST HTTP output should come from code like the following:

 

header ('location:http://www.yoursite.com/'.$_SERVER['HTTP_REFERER']);

 

Depending on your site structure, this may work as well:

 

header ('location:your_folder/'.$_SERVER['HTTP_REFERER']);

 

NOTE: $_SERVER['HTTP_REFERER'] will not likely pass variables such as $_GET values, so you may need to manually build a code referral method and use that for the login. here is what I used recently on a site:

 

// sets referral page for login
if ($_GET['action'] != 'login') {
unset($_SESSION['refer']);
foreach ($_GET as $field=>$value) {
	$bld_refer .= '&'.$field.'='.strip_tags($value);
}
$_SESSION['refer'] = '?'.ltrim($bld_refer,'&');
}

//processes login
	switch ($get['task']) {
		case 'logout':
			$refer = $_SESSION['refer'];
			$new_user->logout_user();
			header('Location:'.$refer);
		break;
		case 'login':
			$vars = new variables($db);
			$req = $vars->req_fields();
			$entries = $new_user->usrLogin($_POST,$req['login']);
			if (isset($entries['error'])) { 
				$this_form->login_form($entries,$entries);
			} else {
				header('Location:'.$_SESSION['refer']);
			}
		break;
	}

 

I do have some classes that process the login, but if the method returns true, it kicks the user to the page the logged in from.

 

Hope that helps

It was better for me to use this:

function curPageURL() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
$r=curPageURL();
$_SESSION['REFERER']=$r;

 

Because I also needed to record the direct input from the browser.  Thanks for your help though!
