I'm using this function in functions.php to auto log in users after the sign up in the front-end

function auto_login_new_user( $user_id ) {
add_action( 'user_register', 'auto_login_new_user' );

This works great for auto login in users but for some reason this also causes the automatic confirmation email not being sent to users anymore. I have no idea why though, any suggestions would be really helpful.

You're short-circuiting the registration process when you redirect and exit script execution, the user_register action isn't the last step of the process. You can try to call wp_new_user_notification manually, but I'm not sure what other side-effects that may have.

  • Thanks a lot for the tip. I added this line before the exit command. This sends an email to admin but it doesn't send an email to the registered user, is there a way to get the email to the user as well? Jun 14, 2014 at 8:58
  • Okay I get it to work by removing the exit command from the function, but I'm getting the admin email twice for some reason for each user Jun 14, 2014 at 11:16

may be the wp_redirect causing the problem. you must call wp_new_user_notification before the redirect.

May be a problem here - see the note on wordpress codex and the example in the codex

<?php wp_new_user_notification( $user_id, $plaintext_pass ) ?>

Note: If password is not passed to function, the newly registered user will not receive their welcome email.
