How to place login logout link on menu that redirects users back to current page?

Question

I am working on an area of my site for members. However, I need a link on my menu that when clicked it will take people to my login form then back to the page they were previously on. I need the same with log out.

Example: Bob logs in on page A. Bob has a successful login. Bob is returned to page A.

Bob clicks the logout link on page A. Bob is returned to page A after being logged out.

EDIT: The other question did not seem to have anyway to add a login logout link to the navigation menu. This is what I need acomplished. Thanks for your help.

Answer 1

Use wp_login_url() function with get_permalink() as a parameter, if a user is not logged in. Something like this:

<a href="<?php echo wp_login_url( get_permalink() ); ?>" title="Login">Login</a>

And wp_logout_url function with get_permalink() as a parameter, if a user is logged in.

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

EDIT: instead of using 2 different functions, you may use

<?php wp_loginout(get_permalink()); ?>

that displays a login link, or if a user is logged in, displays a logout link

This is the code that fixed my problem:

add_filter( 'wp_nav_menu_items', 'add_login_logout_link', 10, 2 ); 

function add_login_logout_link( $items, $args ) {
    $pageURL  = 'http://';
    $pageURL .= $_SERVER['HTTP_HOST'];
    $pageURL .= $_SERVER['REQUEST_URI'];

    ob_start();
    wp_loginout( $pageURL );
    $loginoutlink = ob_get_contents();
    ob_end_clean();
    $items .= '<li>'. $loginoutlink .'</li>';
    return $items;
}
