Auto login after successful activation link

I think this could help:
https://www.ads-software.com/support/topic/auto-login-redirect-after-registration/

But probably on a different hook.

I tried that code a week ago, it doesn′t work. Why you said it needs a different hook…? that code is made for theme my login.

Thanks.

Because this hook is fired when the user is added to the database (still pending), not when the activation is completed. Therefore, the code (wp_set_auth_cookie and wp_redirect) is correct, but fired too early in the workflow, if I understand your question correctly.

I suspect the hook ‘tml_new_user_activated’ is the one you are looking for
https://github.com/jfarthing84/theme-my-login/blob/4047d9a0e58cd459b742d741dd85119681427428/modules/user-moderation/user-moderation.php#LC373

I was wrong, my bad. I see tml_new_user_activated triggers register_new_user through the new_user_activated method.

So then, describe “it doesn′t work” ??

I just tried this way in login-form.php, but it doesn′t work neither.

<?php
function auto_login_new_user( $user_id ) {
wp_set_current_user($user_id);
wp_set_auth_cookie($user_id);
wp_redirect( ‘https://www.example.com/&#8217; );
exit;
}
add_action( ‘new_user_activated’, ‘auto_login_new_user’ );?>
