I am trying to create a WordPress theme from scratch using bootstrap I am using a file I got from GitHub and have implemented a lot of things from it. You can find it in Github . The name is : twittem/wp-bootstrap-navwalker
now I am creating menus / registering menu area and have used the following code :
<?php
require_once('wp_bootstrap_navwalker.php');
//theme support
function theme_setup(){
//nav menu
register_nav_menus(array(
'primary' => __('Primary Menu')
));
}
//for the above function to work we need tocreate an addaction function, which lets us choose a hook to run it
//the one we want is aftr set up theme
add_action('after_setup_theme','wpb_theme_setup');
After doing this the menu shows up but there is an error above it which is :
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'wpb_theme_setup' not found or invalid function name in C:\wamp\www\wordpress-bootstrap\bootstrap\wp-includes\plugin.php on line525
