In order to be semantic it should be...
Code: Select all
<ul>
<li><a href="#">Link</a>
<ul>
<li><a href="#">Link</a>
<ul>
<li><a href="#">Link</a>
</ul>
</li>
</ul>
</li>
</ul>

I've taken that which only supports 2 levels and hacked it somewhat. Without even considering the implications of code standard i dare to submit it below.
Hope it's useful to someone.
Code: Select all
$this->load->model('tool/seo_url');
$results = $this->model_catalog_category->getCategories();
if($results)
{
$output = '<ul>';
}
$output .= '<li><a href="/">Home</a></li>';
$counter = 0;
foreach ($results as $result)
{
// HTML
$output .= '<li class="nav-item-'.$counter.'">';
// Grab the specific category, reset each loop
$new_path = $result['category_id'];
// Prepare the URL
$unrewritten = HTTP_SERVER.'index.php?route=product/category&path=' . $new_path;
// Pass it to the SEO URL tool
$rewritten = $this->model_tool_seo_url->rewrite($unrewritten);
// Output the path and category name
$output .= '<a href="' . $rewritten . '">' . $result['name'] . '</a>';
$counter++;
// Next level deep with the current category as the parameter.
// Children of
$sub_results = $this->model_catalog_category->getCategories($new_path);
// If there are subs
if ($sub_results)
{

$output .= '<ul>';
