You’re using the filter wrong. If you got more than one @param, then you have to state them when adding the filter. function wpse40745_redirect_on_login( $redirect_to, isset( $_REQUEST[‘redirect_to’] ), $user ) { # uncomment the following line if it’s not working and replace $user->roles[0] with something that works // echo ‘<pre>’; print_r( $user ); echo ‘</pre>’; … Read more
This simple to implement, you could put this into functions.php if you want it tied to a theme, or else create your own plugin from this: add_action(‘init’,’my_force_login’); function my_force_login(){ if ( !is_user_logged_in() && !in_array( $GLOBALS[‘pagenow’], array( ‘wp-login.php’, ‘wp-register.php’ ) ) ) { $force_login=get_option(‘my_force_login’); if($force_login){ wp_redirect( wp_login_url() ); exit; } } } For this to work … Read more

In a multi-site installation it is ‘wpmu_validate_user_signup’: add_filter( ‘wpmu_validate_user_signup’, ‘wpse_77904_mu_no_at_in_username’ ); function wpse_77904_mu_no_at_in_username( $user ) { if ( FALSE !== strpos( $user[‘user_name’], ‘@’ ) ) $user[‘errors’]->add(‘user_name’, __( ‘That username is not allowed.’ ) ); return $user; } On single-site it is ‘validate_username’: add_filter( ‘validate_username’, ‘wpse_77904_no_at_in_username’, 10, 2 ); function wpse_77904_no_at_in_username( $valid, $username ) { if … Read more
