I am trying to set up the following:
auth.example.com
sub1.example.com
sub2.example.com
If the user visits sub1.example.com
or sub2.example.com
and they are not logged in, they get redirected over to auth.example.com
and can log in.
sub1.example.com
and sub2.example.com
are two separate applications but use the same credentials.
I tried setting the following in my php.ini:
session.cookie_domain = ".example.com"
but it doesn't seem to be passing the information from one domain to the other.
[Edit]
I tried the following:
sub1.example.com/test.php
session_set_cookie_params(0, '/', '.example.com');
session_start();
print session_id() . "<br>";
$_SESSION['Regsitered'] = 1;
echo '<a href="http://auth.example.com/test.php">Change Sites</a>'
auth.example.com/test.php
session_set_cookie_params(0, '/', '.example.com');
session_start();
print session_id() . "<br>";
$_SESSION['Checked'] = 1;
print_r($_SESSION);
The session IDs are exactly the same but when I dump out the $_SESSION
variable it doesn't show both keys, just whatever key I set under each domain.
I do not know if the problem still exists, but I just ran into the same problem and solved it setting a session name before calling session_set_cookie_params()
:
$some_name = session_name("some_name");
session_set_cookie_params(0, '/', '.example.com');
session_start();
I have changed nothing in my php.ini
but now everything is working fine.
