Question

我在名为“主菜单”的管理面板中创建了wp菜单，然后我尝试在标题中检索它。我得到的物品却无法让孩子低于父母。

在我的HTML模板中，菜单结构如下：

<ul class="rd-navbar-nav">
    <li class="active"><a href="./">Home</a>  </li>
    <li><a href="#">About us</a> 

    <li><a href="#">Products</a> 
    <ul class="rd-navbar-megamenu"> 
        <li>
            <ul class="rd-megamenu-list">
                <li><a href="product-catalog.html">Product 1</a></li> 
                <li><a href="product-catalog.html">Product 1</a></li> 
                <li><a href="product-catalog.html">Product 1</a></li> 
            </ul>
        </li>
    </ul>
    <li><a href="#features">Services</a> 
    <ul class="rd-navbar-megamenu">   
        <li> 
            <ul class="rd-megamenu-list">
                <li><a href="classic-news.html">Service 1</a></li>
                <li><a href="classic-news.html">Service 2</a></li>
                <li><a href="classic-news.html">Service 3/a></li>
                <li><a href="classic-news.html">Service 4</a></li>          
            </ul>
        </li> 
        <li> 
            <ul class="rd-megamenu-list">
                <li><a href="classic-news.html">Service 5</a></li>
                <li><a href="classic-news.html">Service 6</a></li>
                <li><a href="classic-news.html">Service 7</a></li>
                <li><a href="classic-news.html">Service 8</a></li>
            </ul>
        </li>

        <li>
           <!--<p class="rd-megamenu-header">Samouklapajući limovi</p>-->
          <ul class="rd-megamenu-list">
            <li><a href="classic-news.html">Service 5</a></li>
                <li><a href="classic-news.html">Service 6</a></li>
                <li><a href="classic-news.html">Service 7</a></li>
                <li><a href="classic-news.html">Service 8</a></li>
          </ul>
        </li>
    </ul>
    <li><a href="#">News</a>
    <li><a href="careers.html">Careers</a></li>

    <li><a href="contacts.html">Content</a></li>
</ul>

在header.php中的

我在WP管理面板中创建的retreive菜单。它组织得很好，但我唯一的麻烦就是打印

标签。如果打印了四个

，我想在下面创建新的一行块

<li> // Here I need to count how many times is printed, if more than 4 then I shoud create new row
                  <ul class="rd-megamenu-list">
                    <a href="<?php echo $link; ?>" class="title"><?php echo $title; ?></a>
                  </ul>
                </li>



   <ul class="rd-navbar-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>
    <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="rd-navbar-megamenu">
        <?php endif;?>
            <li> // Here I need to count how many times is printed, if more than 4 then I shoud create new row
              <ul class="rd-megamenu-list">
                <a href="<?php echo $link; ?>" class="title"><?php echo $title; ?></a>
              </ul>
            </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; ?>

任何建议都有帮助

检查<li>标签的打印次数，如果有更多次创建新行
