Generate a custom structure for Wordpress menus.

readme.md

This gist is for showing an example of a custom wordpress menu.

If you want to get more from the menu item simply have a look at the $item object. i.e:

// Will return a large object with lots of props like title, url, description, id etc.
var_dump( $item );

This code works on Wordpress 4.1.1 as of 31st of March 2015

wp_custom_nav.php
<?php
$menu_name = 'main_nav';
$locations = get_nav_menu_locations();
$menu = wp_get_nav_menu_object( $locations[ $menu_name ] );
$menuitems = wp_get_nav_menu_items( $menu->term_id, array( 'order' => 'DESC' ) );
?>
<nav>
<ul class="main-nav">
<?php
$count = 0;
$submenu = false;
foreach( $menuitems as $item ):
$link = $item->url;
$title = $item->title;
// item does not have a parent so menu_item_parent equals 0 (false)
if ( !$item->menu_item_parent ):
// save this id for later comparison with sub-menu items
$parent_id = $item->ID;
?>
<li class="item">
<a href="<?php echo $link; ?>" class="title">

The problem is in the ( $parent_id == $item->menu_item_parent ) statements.

While looping a third level menu-item, the parent_id is the ID of the parent item (so second level), while the $parent_id is the top-parent ID.

We've solved this to change $parent_id to an array which contains all of the previous menu-item ID's.
After that, improve the statements with the in_array($item->menu_item_parent, $parent_id) function.

I can't seem to figure out how to put a class (like .menu-item-has-children for example) on the li that has children. Any help?

And get my required output.

Why don't you use recursion? It is a very simple way and works for the menus with multiple levels.

That code just doesn't work properly, I ended up just adding the menu items into a PHP array so I could output easily.

Add the following into your functions.php then call in your theme passing the menu of choice.

function wp_get_menu_array($current_menu) {
    $array_menu = wp_get_nav_menu_items($current_menu);
    $menu = array();
    foreach ($array_menu as $m) {
        if (empty($m->menu_item_parent)) {
            $menu[$m->ID] = array();
            $menu[$m->ID]['ID']          =   $m->ID;
            $menu[$m->ID]['title']       =   $m->title;
            $menu[$m->ID]['url']         =   $m->url;
            $menu[$m->ID]['children']    =   array();
        }
    }
    $submenu = array();
    foreach ($array_menu as $m) {
        if ($m->menu_item_parent) {
            $submenu[$m->ID] = array();
            $submenu[$m->ID]['ID']       =   $m->ID;
            $submenu[$m->ID]['title']    =   $m->title;
            $submenu[$m->ID]['url']      =   $m->url;
            $menu[$m->menu_item_parent]['children'][$m->ID] = $submenu[$m->ID];
        }
    }
    return $menu;
}

Then call in your theme $menu_items = wp_get_menu_array('main-menu');

  <nav>
      <ul>
        <?php foreach ($menu_items as $item) : ?>
          <li>
            <a href="<?= $item['url'] ?>" title="<?= $item['title'] ?>"><?= $item['title'] ?></a>
            <?php if( !empty($item['children']) ):?>
            <ul class="sub-menu">
              <?php foreach($item['children'] as $child): ?>
                <li class="b-main-header__sub-menu__nav-item">
                  <a href="<?= $child['url'] ?>" title="<?= $child['title'] ?>"><?= $child['title'] ?></a>
                </li>
              <?php endforeach; ?>
            </ul>
            <?php endif; ?>
          </li>
        <?php endforeach; ?>
     <ul>

Hi, has anyone found a solution for the third level menu? The third level menu does not appear on my website.
In addition, the name of the main menu appears in the submenus. I have shared the sample picture.

This works nicely, thanks. Any tips on how to approach getting the current menu item styled?

Bu kod düzgün çalışmıyor, kolayca çıktı alabilmek için menü öğelerini bir PHP dizisine ekledim.

Aşağıdakileri function.php dosyanıza ekleyin ve ardından seçtiğiniz menüden temanızı çağırın.

function wp_get_menu_array($current_menu) {
    $array_menu = wp_get_nav_menu_items($current_menu);
    $menu = array();
    foreach ($array_menu as $m) {
        if (empty($m->menu_item_parent)) {
            $menu[$m->ID] = array();
            $menu[$m->ID]['ID']          =   $m->ID;
            $menu[$m->ID]['title']       =   $m->title;
            $menu[$m->ID]['url']         =   $m->url;
            $menu[$m->ID]['children']    =   array();
        }
    }
    $submenu = array();
    foreach ($array_menu as $m) {
        if ($m->menu_item_parent) {
            $submenu[$m->ID] = array();
            $submenu[$m->ID]['ID']       =   $m->ID;
            $submenu[$m->ID]['title']    =   $m->title;
            $submenu[$m->ID]['url']      =   $m->url;
            $menu[$m->menu_item_parent]['children'][$m->ID] = $submenu[$m->ID];
        }
    }
    return $menu;
}

Ardından temanızı arayın $menu_items = wp_get_menu_array('main-menu');

  <nav>
      <ul>
        <?php foreach ($menu_items as $item) : ?>
          <li>
            <a href="<?= $item['url'] ?>" title="<?= $item['title'] ?>"><?= $item['title'] ?></a>
            <?php if( !empty($item['children']) ):?>
            <ul class="sub-menu">
              <?php foreach($item['children'] as $child): ?>
                <li class="b-main-header__sub-menu__nav-item">
                  <a href="<?= $child['url'] ?>" title="<?= $child['title'] ?>"><?= $child['title'] ?></a>
                </li>
              <?php endforeach; ?>
            </ul>
            <?php endif; ?>
          </li>
        <?php endforeach; ?>
     <ul>
</nav>

This code works fine but when I add 3rd level menu it gives the following warning. How can I fix this?
