How to add sequential numbering for wordpress menu

问题:

Currently working on a site and trying to use sequential numbering just before the page titles on a wordpress menu but not exactly sure how to fit the < span> in without removing the page title and also how to get each page numbered sequentially. Current structure of what I am trying to achieve is below -

<ul role='navigation' id='navigation'>
<li class='page_item '><span class="number">1 </span><a href=''>About </a> </li>
<li class='page_item '><span class="number">2 </span><a href=''>Work </a> </li>
<li class='page_item '><span class="number">3 </span><a href=''>Contact </a> </li>
    <li class='page_item '><span class="number">4 </span><a href=''>etc. </a> </li>
</ul>

I started my PHP by using

<li><?php wp_nav_menu( array( 'theme_location' => 'primary', 'menu_class' => 'nav-menu' ) ); ?></li>

My CSS looks like this -

header ul li {
    display:block; 
    float:left; 
    white-space:nowrap; 
    overflow: hidden; 
}

header .number { 
    padding-left: 4px;
    text-align: center; 
    font-size: 14px; 
    vertical-align: middle; 
    line-height: 1px; 
    margin-right: 6px;
}

Fiddle here I came across the Walker nav menu but I can't seem to comprehend it on my own. Any help would be appreciated.

Since you can't change the element type of to then you can change the format of the output using css.

#navigation ul {
  counter-reset: section;
  list-style-type: none;
}

#navigation li:before {
  counter-increment: section; 
  content: counters(section, ".") ": "; 
  color: red;
  font-weight: bold;
}

See jsFiddle for details.

You could try sticking the page number and title in an array, then looping through

$pages = array(
    1 => array(
        'title' => 'About',
        'url' => 'about.php'
    ),
    2 => array(
        'title' => 'Work',
        'url' => 'work.php'
    ),
    3 => array(
        'title' => 'Contact',
        'url' => 'contact.php'
    ),
    4 => array(
        'title' => 'etc',
        'url' => 'someFilename.php'
    )
);
foreach($whats as $name => $page) {
    printf("<a href='%s'>%s</a> ", $page['url'], $page['title']);

Then again, you could just use Jeff's idea and use <ol></ol> instead of <ul></ul> - which would make more sense and be a hell of a lot easier! xD
