混淆了如果是那么复杂的条件

Question

我正在使用数组创建一个菜单。目前，我陷入了困惑的境地:如何向所有的孩子展示菜单上的所有内容。以下是代码：

      <ul class="nav navbar-nav">
<?php
$get_admin_menu = get_admin_menu(); 
$get_admin_submenu = get_admin_submenu(); 
foreach( $get_admin_menu as $menu ){
    $mi = 1;
    $menu_title = $menu["title"];
    $menu_slug = $menu["slug"];
    $menu_url = $menu["url"];

    echo "<li class=\"dropdown\">";
    echo "<a href=\"$menu_url\">";
    echo $menu_title;
    echo "</a>";

    $si = 0;
    $total = count($get_admin_submenu);
    foreach( $get_admin_submenu as $menu ){
        $mi++;
        $submenu_title = $menu["title"];
        $submenu_slug = $menu["slug"];
        $submenu_parent = $menu["parent"];
        if( $menu_url == $submenu_parent ){
            $si++;
            if( $si == 1 ){ echo "<ul class=\"dropdown-menu\" role=\"menu\">"; }
            echo "<li>";
            echo "<a href=\"$submenu_parent?page=$submenu_slug\">";
            echo $submenu_title;
            echo "</a>";
            echo "</li>";
        }
        if( $si == 1 ){ echo "</ul>"; break; }
    }
    echo "</li>";
}
?>
        </ul>

这是代码，菜单和子菜单是如何被处理到数组中的

Answer 1

在第一个菜单子元素之后，您就中断了循环。在循环的末尾，您有：

if( $si == 1 ) { echo "</ul>"; break; }

在这里试试这个：

if( $si >= ($total - 1) ) { echo "</ul>"; break; }
