Ahh, you’re using Thematic. The problem is that this code:
<?php wp_page_menu('sort_column=menu_order') ?>
Generates this HTML:
<div class="menu">
<ul>
<li class="page_item page-item-2"><a href="https://syw6mm.com/minirev/about/" title="About">About</a></li>
<li class="page_item page-item-103"><a href="https://syw6mm.com/minirev/contact/" title="Contact">Contact</a></li>
</ul>
</div>
So you can see that if you add a link after that, it will be outside of the division and the unordered list.
You you need to generate your list differently. You will have to do a little experimentation, but if you replace this line in your header:
<?php wp_page_menu('sort_column=menu_order') ?>
With this code:
<div class="menu">
<ul>
<?php wp_list_pages('title_li=&sort_column=post_title' ) ?>
</ul>
</div>
That should generate the same HTML you have right now. The difference is that you have the division and the unordered list hardcoded in your header, so you can manually insert links in that list, before or after the PHP generated list.
So if you modified it to look like this:
<div class="menu">
<ul>
<?php wp_list_pages('title_li=&sort_column=post_title' ) ?>
<li class="page_item page-item-103"><a href="https://syw6mm.com/minirev/contact/" class="smcf-link">Contact</a></li>
</ul>
</div>
You should have the contact link you need at the end of the list, with the class you need in the anchor.
One problem though, you have two Contact links now. You need to exclude the Contact Page from that list. Just change this line of code:
<?php wp_list_pages('title_li=&sort_column=post_title' ) ?>
To this:
<?php wp_list_pages('exclude=2&title_li=&sort_column=post_title' ) ?>
That will exclude a Page with the ID of “2” from your list. In your case, About actually has the post ID of 2, so you will need to change this to the post ID of your Contact Page.
You can easily find out the ID by editing your Page, the URL of that Page will end in “post=ID”.
Good luck, oh and sweet miniatures!
