I have a form that creates a new user by using:


This works, but after this I want to auto log in the user.

I tried using:

$creds = array();
$creds['user_login'] = 'username';
$creds['user_password'] = 'password';
$creds['remember'] = true;
$user = wp_signon( $creds, false );
    if ( is_wp_error($user) ) {
       $msg =  $user->get_error_message();
    } else {
        $output_form = true;

But this creates a "headers already sent" error message because it's not at the top of the page.

Is there a way to auto log in the user after I have created the user?

Works if I add this right after the creation: wp_set_current_user($user_id); – redconservatory Aug 5 '11 at 15:44

Here is a function I wrote that hooks into the gravity forms create user form but it can be added to whatever action hook your wp_create_user function is attached to.

function my_auto_login( $user_id ) {
    wp_set_auth_cookie( $user_id, false, is_ssl() );
    wp_redirect( admin_url( 'profile.php' ) );

The important part is wp_set_auth_cookie. This has to fire after the user is the best (only?) way to auto login a user without filling out the login form.

You should probably use the action hook init to catch and process the registration form. This hook is called before anything is sent to the browser. If the form validates...

  • Create the user with wp_create_user
  • Log in the user with wp_signon
  • Redirect the user using wp_redirect to the page of your choice

Thanks but as I mentioned in my question I am getting a error message with wp_signon if I don't put it at the beginning of the page...trying to stay on the same page if possible. – redconservatory Aug 5 '11 at 15:42
The point is that you have do wp_signon before output, since that function sets headers. You have to deal with the form submission before WP starts rendering the page. – Chris Carson Aug 5 '11 at 15:53
