how to do logout redirect to current url

Question

I'm using custom menu for login/logout here below is my code:

<?php
   if(is_user_logged_in()) {
      $user = wp_get_current_user();
      echo 'Welcome <strong><a href="http://gopalbonline.com/kolkataonwheels/wp-admin/index.php" >'.$user->user_firstname.'</a></strong>
  | <a href="<?php echo wp_logout_url( get_permalink() ); ?>" title="Logout">Logout</a>';
   } else { ?>
      <strong><?php wp_loginout(); ?></strong>
      or <a href="<?php bloginfo('url') ?>/wp-login.php?action=register">     <strong>Register</strong></a>
<?php } ?>

but problem is :

1. redirect to 404 page not current page...
2. I want to add user gavatar if he/she logged in

Any help greatly appreciated.

Answer 1

wp_loginout(get_permalink()); will make hyperlink with "Log out/Log in" text and after log out it will stay in the same page, or it will direct user to log in page.

Answer 2

something like this

function my_redirect(){
    $redirect_url = $_SERVER['HTTP_REFERER'];
    if(!empty($_REQUEST['redirect_to'])){
        wp_safe_redirect($_REQUEST['redirect_to']);
    } else {
        wp_redirect($redirect_url);
    }
    exit();
}
add_filter('wp_logout','my_redirect');

Answer 3

For example:

<a href="<?php echo wp_logout_url( get_permalink() ); ?>" title="Logout">Logout</a>

Can all be done with WP functions - no custom code required in this case.

You just need to move the code from function.php into the theme and it should work.
