Regular expressions: convert to WordPress
- SOLVED
I need to convert a standard WordPress menu into a <select></select> combobox using a series of preg_replace statements or a similar PHP-based solution. This is what I have:
<ul id="nav" class="sf-menu">
<li><a href="/">Home</a></li>
<li class="page_item page-item-55"><a href="http://www.domain.com/some-link-1" title="About David"><span>About David</span></a></li>
<li class="page_item page-item-69"><a href="http://www.domain.com/some-link-2" title="Workshops & Events"><span>Workshops & Events</span></a></li>
<li class="page_item page-item-156"><a href="http://www.domain.com/some-link-3" title="Articles"><span>Articles</span></a></li>
<li class="page_item page-item-61"><a href="http://www.domain.com/some-link-4" title="David’s Blog"><span>David’s Blog</span></a></li>
<li class="page_item page-item-82"><a href="http://www.domain.com/some-link-5" title="Testimonials"><span>Testimonials</span></a></li>
<li class="page_item page-item-147"><a href="#" title="Resources"><span>Resources</span></a>
<ul>
<li class="page_item page-item-150"><a href="http://www.domain.com/some-link-7" title="FAQs"><span>FAQs</span></a></li>
<li class="page_item page-item-152"><a href="http://www.domain.com/some-link-8" title="Links"><span>Links</span></a></li>
</ul>
</li>
<li class="page_item page-item-89"><a href="http://www.domain.com/some-link-9" title="Contact Me"><span>Contact Me</span></a></li>
</ul>
And this is what I want to convert it to:
<select id="nav" class="sf-menu">
<option><a value="/">Home</option>
<option class="page_item page-item-55" value="http://www.domain.com/some-link-1"><span>About David</span></option>
<option class="page_item page-item-69" value="http://www.domain.com/some-link-2"><span>Workshops & Events</span></option>
<option class="page_item page-item-156" value="http://www.domain.com/some-link-3"><span>Articles</span></option>
<option class="page_item page-item-61" value="http://www.domain.com/some-link-4"><span>David’s Blog</span></option>
<option class="page_item page-item-82" value="http://www.domain.com/some-link-5"><span>Testimonials</span></option>
<option class="page_item page-item-147" value="#"><span>Resources</span></option>
<option class="page_item page-item-150" value="http://www.domain.com/some-link-7"><span class="indent">FAQs</span></option>
<option class="page_item page-item-152" value="http://www.domain.com/some-link-8"><span class="indent">Links</span></option>
<option class="page_item page-item-89" value="http://www.domain.com/some-link-9"><span>Contact Me</span></option>
</select>
Please note that one of the menu items has a submenu under it and it results in <option> items that contain <span class="indent">. Again, if you have other ideas on how to accomplish this, I'm open to them as long as I can use PHP to do it and it will work within WordPress.
Thanks!

Try this: (replace 'primary' with your nav menus slug, or ID)
$nav_menu_items = wp_get_nav_menu_items('primary');
echo '<select id="nav" class="sf-menu">';
foreach($nav_menu_items as $nav_menu_item) {
$class = "page_item page-item-{$nav_menu_item->ID}";
if($nav_menu_item->menu_item_parent == '0') {
$content = "<span>{$nav_menu_item->title}</span>";
} else {
$content = "<span class='indent'>{$nav_menu_item->title}</span>";
}
$value = $nav_menu_item->url;
echo "<option class='$class' value='$value'>$content</option>";
}
echo '</select>';

Why not building a custom walker nav instead of preg replacing? I think it would be better.
Here are two resources for building custom walker -
