How can I programatically change menu in Wordpress? - php

Question

I've created one menu in Norwegian menu_no and one in English menu_en.
I can see that my theme supports only one menu, but I'm not planning on using more that one menu at a time. So when user selects English language, how can I change the active menu?
I've not found anything on Google and I can't find the right function in nav-menu.php.
UPDATE
I found quite a simple solution for my problem. I just had to think a bit differently. In my functions.phpI added this code:
add_action('init', 'register_menus');
function register_menus(){
register_nav_menus( array(
'menu_no' => 'Norwegian menu',
'menu_en' => 'English menu',
) );
}
and in my header.php file I use this code:
global $lang;
$args = array(
'theme_location' => 'menu_'.$lang,
'container' => false
);
<?php wp_nav_menu($args); ?>
Voila. I'll post it as answer later - if not anyone else comes up with a better idea.

Answer 1

Here is How You Can Do That.
Past this code to function.php file
// Register Navigation Menus
function custom_navigation_menus() {
$locations = array(
'first_menu' => __( 'Menu for English language', 'text_domain' ),
'second_menu' => __( 'Menu for Other Language', 'text_domain' ),
);
register_nav_menus( $locations );
}
// Hook into the 'init' action
add_action( 'init', 'custom_navigation_menus' );
You can customize the above code.
Now use wp_nav_menu function to display anywhere you want like this
<?php
wp_nav_menu( array(
'menu' => 'primary',
'theme_location' => 'first_menu',
);
?>
<?php
wp_nav_menu( array(
'menu' => 'secondary',
'theme_location' => 'second_menu',
);
?>
You can display each menu in different places. Now you to Option in you menu Primary and Secondary
