How do I return an array of pages using this plugin?

<?php wp_nav_menu(); ?>

So I want to use the above function to spit out my nav links with the class "topnav" and each one with a sequential ID.

Example of what I want:

<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>

Is this possible to do? If so, how? Can you do it with arguments?

I suppose the "hard part" is sequentially labeling the IDs as well as the custom link location.

Ultimately I am trying to make something similar to the below code work with Exclude Pages plugin.

<?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++;
            }       
        ?>

So I need help either modifying the above PHP code or wp_nav_menu(). Any suggestions?

UDPATE !!!!!!!

Better question! How do I return an array of pages using the Exclude Pages plugin? Here's the plugin code:

<?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.

I think this will be much simpler.

You can do that without any plugins. You need to use wp_get_nav_menu_items function. First create menu in admin. You need to replace testmenu (with you custom menu title) in following code to get this to work properly. I presume you want some real url in href attributes, if not replace it with $counter. And number as id is only valid in html5, so use with caution.

<?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)

 ?>

I replied to your original question.

The page IDs excluded by the Exclude Pages plugin (as unchecked in the UI) are stored as a comma separated string in an option called 'ep_exclude_pages'. You can get this by using the following code:

$excluded = get_option( 'ep_exclude_pages', '' );

Hope this helps.
