wp_list_pages具有顺序编号的当前页面的子项

Question

I'm currently using this code to output (using wp_list_pages) a list of the current page children.

<?
if(wp_list_pages('child_of='.$post->ID.'&echo=0&exclude=2')) {
wp_list_pages('title_li=&child_of='.$post->ID.'&exclude=2');
}
elseif(get_the_title($post->post_parent) != the_title(' ' , ' ',false)) {
wp_list_pages('child_of='.$post->post_parent.'&title_li=&exclude=2');
} ?>

I would like to merge this code with another piece that enables me to add sequential numbering to the li elements, as shown here.

<?php $list_of_pages = wp_list_pages('echo=0&title_li=&depth=1' );
$list_pages = explode('<li class="',$list_of_pages); $len = count($list_pages);
for ($i = 0; $i <= $len-2; $i++) :
echo $list_pages[$i] . '<li  class="link-' . ($i+1) . ' ';
endfor; echo $list_pages[$i]; ?>

But i'm not particularly handy with PHP, if anyone could point me in the right direction to use the two snippets of code combined it would be much appreciated.

It is a bit messy but it works and there is always room for refactoring the code below in the future. The code below first checks to see if a page is the parent of child page. If it is the child page it will only show the child. It adds an incremental counter to every list item(even the children) and the counter is initiated by calling echo=0. Hope this helps

<?php

    if(wp_list_pages('child_of='.$post->ID.'&echo=0&exclude=2')) {
        $list_of_pages = wp_list_pages('echo=0&title_li=&child_of='.$post->ID.'&exclude=2');
        $list_pages = explode('<li class="',$list_of_pages); $len = count($list_pages);
        for ($i = 0; $i <= $len-2; $i++) :
        echo $list_pages[$i] . '<li class="link-'.($i+1). ' ';
        endfor; echo $list_pages[$i]; 
    }

    elseif(get_the_title($post->post_parent) != the_title(' ' , ' ',false)) {
    $list_of_pages = wp_list_pages('echo=0&child_of='.$post->post_parent.'&title_li=&exclude=2');
    $list_pages = explode('<li class="',$list_of_pages); $len = count($list_pages);
    for ($i = 0; $i <= $len-2; $i++) :
    echo $list_pages[$i] . '<li class="link-'.($i+1). ' ';
    endfor; echo $list_pages[$i];

} ?>
