An Example of Menu ACF usage

Here is an example. I had a situation where I needed to use different menus based on the page (not my idea!). So I added a Menu ACF field to the page post type. I used the Menu ID as what would be returned.

In my functions file I registered my menus

<?php
register_nav_menus( array(
‘primary’ => __( ‘Main Menu Live’, ‘main-menu’ ),
‘primaryvirtual’ => __( ‘Main Menu Virtual’, ‘main-menu-virtual’ ),
‘naemea’ => __( ‘North America and EMEA Menu’, ‘naemea-menu’ ),
‘apac’ => __( ‘APAC Menu’, ‘apac-menu’ )
) );

?>

In the header.php file of my theme I then dynamically call the menu.

<?php

if (class_exists(‘ACF’)) {
$main_menu= get_field(‘main_menu’, get_the_ID());
}

$theme_location = ‘primary’;

switch ($main_menu) {
case 3:
$theme_location = ‘primary’;

break;
case 7:
$theme_location = ‘naemea-menu’;

break;
case 8:
$theme_location = ‘apac-menu’;

break;
default:
$theme_location = ‘primary’;
}

?>

Then change the wp_nav_menu this way.

<?php

wp_nav_menu(array(
‘menu’ => $main_menu,
‘theme_location’ => $theme_location,
‘depth’ => 3,
‘container’ => ‘div’,
‘container_class’ => ‘collapse navbar-collapse’,
‘container_id’ => ‘bs-navbar-collapse-1’,
‘menu_class’ => ‘nav navbar-nav menu-main-menu’,
‘fallback_cb’ => ‘WP_Bootstrap_Navwalker::fallback’,
‘walker’ => new WP_Bootstrap_Navwalker(),
));

?>

Hope that helps those lost in the WordPress php world.
