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">
            <?php echo $title; ?>
        </a>
    <?php endif; ?>

        <?php if ( $parent_id == $item->menu_item_parent ): ?>

            <?php if ( !$submenu ): $submenu = true; ?>
            <ul class="sub-menu">
            <?php endif; ?>

                <li class="item">
                    <a href="<?php echo $link; ?>" class="title"><?php echo $title; ?></a>
                </li>

            <?php if ( $menuitems[ $count + 1 ]->menu_item_parent != $parent_id && $submenu ): ?>
            </ul>
            <?php $submenu = false; endif; ?>

        <?php endif; ?>

    <?php if ( $menuitems[ $count + 1 ]->menu_item_parent != $parent_id ): ?>
    </li>                           
    <?php $submenu = false; endif; ?>

<?php $count++; endforeach; ?>

</ul>
</nav>

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?

better code readability

<?= $page->post_title ?>

this is not happening. main code becomes but dropdown icon disappears
