WP LINK LOGIN

This plugin add a link for login and logout to each page on your weblog.

edik

The plugin adds the ‘redirect_to’ parameter to all login and logout links in front-end. The value is the URL of the current site. Thus you’re redirected to that site after login respectively logout. But if a link contains already a ‘redirect_to’ parameter, the plugin doesn’t change it.
The Plugin affects only the links in front-end. These in wp-login.php and in admin back-end aren’t touched.
The plugin hooks into <a href="https://codex.wordpress.org/Plugin_API/Filter_Reference/login_url" rel="nofollow ugc">login_url</a> and <a href="https://codex.wordpress.org/Plugin_API/Filter_Reference/logout_url" rel="nofollow ugc">logout_url</a>. Your code has to call functions which make use of that filters. For example <a href="https://codex.wordpress.org/Function_Reference/wp_loginout" rel="nofollow ugc">wp_loginout</a>.

Login Redirection Link

Redirects users to the previous url after login ( and logout ) by adding a redirection parameter to the links.
