There are 3 shortcodes that can be used:
<pre><code>[logout] - A standard Log Out link, where the user stays on the login screen after being logged out.
[logout_to_home] - A link that logs the user out, and redirects them to your home page.
[logout_to_current] - A link that logs the user out, and redirects them back to the current page/URL.
</code></pre>
Advanced Usage:
All 3 shortcodes all support 3 attributes/parameters:
<pre><code>[logout text="" class="" redirect=""]
</code></pre>
The 3 supported attributes/parameters are:
<pre><code>text=""
</code></pre>
– The text to use for the link anchor text. 
– Default: <code>Log Out</code> 
 class=”” 
– The HTML class(es) to use for the link. Multiple classes should be separated by a space. 
– Default: <code>logout</code> 
 redirect=”” 
– The path/URL to redirect the user to after they are logged out. 
– Default: the WordPress login screen. 
– Note: must be a URL or path on the same domain name as the WordPress website (cannot be an external domain/URL)
Some Examples: 
 [logout text=”Log Off”] – A <code>Log Off</code> link that logs the user out. 
 [logout redirect=”/members/”] – Log the user out, and redirect them to <code>/members/</code>. 
 [logout_to_home text=”Log Off”] – A <code>Log Off</code> link that logs the user out and redirects them to your home page. 
 [logout class=”log-out-link”] – Use a custom CSS/HTML class name for the log out link.
Note: the shortcodes will return nothing/empty if the user isn’t logged in.
