How to dynamically create a navigation menu

By automating site creation on WordPress, you can also automate the creation of the site tree structure, for example for a prototype.

In the example below, no pages are used. Navigation is based on custom links, starting from a 2-level navigation defined in the array.

Add this function to your plugin or function file:

<?php
/*
* Create programmatically navigation menu
*/
add_action('after_setup_theme', 'wpster_create_nav_menu');
function wpster_create_nav_menu() {
	$menu_name = 'Menu Principal';
	$menu_exists = wp_get_nav_menu_object($menu_name);
	if (!$menu_exists) {
		$menu_id = wp_create_nav_menu($menu_name);
		$items = array(
			array(
				'Accueil',
			),
			array(
				'Ventes','BMW','Mini','Voir tout',
			),
			array(
				'Carrosserie',
			),
			array(
				'Atelier','Entretien','Réparations','Équipement','Accessoires',
			),
			array(
				'Contact & Accès',
			),		
		);
		foreach($items as $key=>$value):
			$parent = 'parent_'.$key;
			foreach($value as $kvalue=>$vvalue):
				if($kvalue==0):
					$$parent = wp_update_nav_menu_item($menu_id, 0, array(
						'menu-item-title' => __($vvalue), 
						'menu-item-url' => '#',
						'menu-item-status' => 'publish')
					);
				else:
					$child = wp_update_nav_menu_item($menu_id, 0, array(
						'menu-item-title' => __($vvalue), 
						'menu-item-url' => '#',
						'menu-item-parent-id' => $$parent,
						'menu-item-status' => 'publish')
					);
				endif;
			endforeach;
		endforeach;	
	}
}
