I'm implementing an administrative area on my site and have always used $_SESSION to log in. However, now I need the user login to be saved if it leaves the page.
My question: Do I need to use
$_COOKIEto save$_SESSIONinformation or can I use only$_COOKIE?
You can only use $_COOKIE .
You can set the values to a $_COOKIE like this:
setcookie("loginCredentials", $user, time() * 7200); // expira depois de 2 hours
To get around you can just leave the cookie value blank like this:
setcookie("loginCredentials", "");
And finally to verify that the user is logged in:
if(isset($_COOKIE['user']['id'] && !empty(isset($_COOKIE['user']['id']))){
// Usuário logado.
}else{
// Usuário não esta logado.
}
This variable $user could look something like this:
$user = array(
'id' => $id,
'name' => $name,
'login' => $login,
)
Just be careful not to leave passwords and information unprotected.
