How to add Login/Logout Menu Link to wordpress menu

-
Almost nothing is more frustrating for a user than searching around for a login link in order to get to important content.
The following method right on your menu bar.
will automatically detect whether a user is logged in or not and put a login or a logout link
*** Please note, this method only works when you are using WordPress’ custom menus. (The menu function available in the admin section: Appearance > Menus.)

Add Code to Your Functions File

You will need to add a bit of code to your functions file for this. But after copying and pasting this code, you’re finished.
Go to Appearance > Editor > Theme Functions (functions.php). Place the following code in the bottom your functions file and hit “Update File.”
add_filter('wp_nav_menu_items', 'add_login_logout_link', 10, 2); function add_login_logout_link($items, $args) {         ob_start();         wp_loginout('index.php');         $loginoutlink = ob_get_contents();         ob_end_clean();         $items .= '<li>'. $loginoutlink .'</li>';     return $items; }

The Result

Keep in mind that these links will appear wherever you put your custom menus – be they at the top of your page, in your sidebar, or anywhere else.

If you've followed along with my  earlier post , you now have MQTT running on your Raspberry Pi, and an Arduino IoT client that can publish and subscribe to MQTT packets.  The next step is developing a real-time web interface that can control your MQTT network. Why Socket.io and Node.js? Web browsers typically operate by pulling data from a server when you click on a link.  Servers don't usually keep an open connection to the browsers it has serviced, so if some event happens on the server side, the server cannot push that event to your browser, unless you refresh the page. That's where Socket.io comes in handy.  Socket.io maintains an open connection between the server and the browser, which enables the server to push updates to the bro...
