Login/Logout script - by designerobot - on WordPress WooCommerce support

Hello,

The simple way to implement something similar to what you want is:

Create custom menu (Appearance > Menus) http://prntscr.com/kausqj with 3 links, last one should be created using the WC endpoints. Add the custom classes for the first one – hide-for-loggedin and for the next 2 items – hide-for-loggedout . Then add the following custom code in child theme style.css or in Custom CSS field of the parent theme.

.logged-in .widget_nav_menu .hide-for-loggedin {
    display: none;
}
.widget_nav_menu .hide-for-loggedout {
    display: none;
}
.logged-in .widget_nav_menu .hide-for-loggedout {
    display: block;
}

Go to Appearance > Menus add the Navigation Menu widget into sidebar where you want to show the links.

If this way is not suitable for you then you can try to create the special widget in case you have PHP skills or order customization here.

Regards
