Adding a search bar and single post page

So let's get started.

Dealing with the search box

Go to our header file and go to the empty form down at the bottom of the file, and we will add some stuff to it. The first thing we'll do is adding a method and the method is going to be get. We can actually change the class from left to right. We also need to add an action. For that, we will use the php tags and add echo esc_url().

This is because we want the URL checked and escaped. We will use home_url with a /:

<form method="get" class="navbar-form navbar-right" 
 role="search" action="<?php echo esc_url(home_url('/')); ?>">

Basically, we're just submitting...
