<?php wp_nav_menu(); ?>
所以我想使用上面的函数将我的导航链接与“topnav”类和每个带有顺序ID的导航链接一起吐出。
我想要的例子：
<a class="topnav" id="1" href="#1">WP Page 1</a>
<a class="topnav" id="2" href="#2">WP Page 2</a>
<a class="topnav" id="3" href="#3">WP Page 3</a>
<a class="topnav" id="4" href="#4">WP Page 4</a>
<a class="topnav" id="5" href="#5">WP Page 5</a>
这可能吗？如果是这样，怎么样？你能用参数做到吗？
我认为“硬件”依次标记ID以及自定义链接位置。
最终我尝试使用Exclude Pages插件制作类似下面代码的内容。
<?php
$pagepull = $wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_type = 'page' AND post_status = 'publish' ORDER BY menu_order", ARRAY_A);
$i = 1;
foreach ($pagepull as $single_page){
echo "<a class=\"topnav\" id=\"nav" . $i . "\" href=\"#" . $i . "\">" . $single_page['post_title'] . "</a>";
$i++;
}
?>
所以我需要帮助修改上面的PHP代码或wp_nav_menu（）。有什么建议吗？
UDPATE !!!!!!!
更好的问题！如何使用Exclude Pages插件返回一系列页面？这是插件代码：
<?php
/*
Plugin Name: Exclude Pages from Navigation
Plugin URI: http://wordpress.org/extend/plugins/exclude-pages/
Description: Provides a checkbox on the editing page which you can check to exclude pages from the primary navigation. IMPORTANT NOTE: This will remove the pages from any "consumer" side page listings, which may not be limited to your page navigation listings.

你可以在没有任何插件的情况下做到这一点。您需要使用wp_get_nav_menu_items功能。首先在admin中创建菜单。您需要在以下代码中替换testmenu（使用自定义菜单标题）才能使其正常工作。我认为你想在href属性中有一些真实的url，如果没有用$counter替换它。并且number as id仅在html5中有效，因此请谨慎使用。
<?php
$items = wp_get_nav_menu_items("testmenu");
$counter = 1;
foreach($items as $item): ?>
<a class="topnav" id="<?php echo $counter; ?>" href="<?php echo $item->url; ?>">WP Page <?php echo $counter; ?> :: <?php echo $item->title; ?></a>
<?php
$counter++;
endforeach;
print_r($items);// remove this after successful implementation, it will show you what you can get from $item(s)
?>
我回复了你原来的问题。
答案 1 :(得分：0)
Exclude Pages插件排除的页面ID（在UI中未选中）将作为逗号分隔字符串存储在名为“ep_exclude_pages”的选项中。您可以使用以下代码获取此信息：
$excluded = get_option( 'ep_exclude_pages', '' );
希望这有帮助。
