Hi !
In PS 1.6 we are this function but this add in sub menu too.
protected function generateCategoriesMenu($categories, $is_children = 0)
{
$html = '';
foreach ($categories as $key => $category) {
if ($category['level_depth'] > 1) {
$cat = new Category($category['id_category']);
$link = Tools::HtmlEntitiesUTF8($cat->getLink());
} else {
$link = $this->context->link->getPageLink('index');
}
/* Whenever a category is not active we shouldnt display it to customer */
if ((bool)$category['active'] === false) {
continue;
}
$html .= '<li'.(($this->page_name == 'category'
&& (int)Tools::getValue('id_category') == (int)$category['id_category']) ? ' class="sfHoverForce"' : '').'>';
$html .= '<a href="'.$link.'" title="'.$category['name'].'">'.$category['name'].'</a>';
if (isset($category['children']) && !empty($category['children'])) {
$html .= '<ul>';
$html .= $this->generateCategoriesMenu($category['children'], 1);
if ((int)$category['level_depth'] > 1 && !$is_children) {
$files = scandir(_PS_CAT_IMG_DIR_);
if (count(preg_grep('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $files)) > 0) {
$html .= '<li class="category-thumbnail">';
foreach ($files as $file) {
if (preg_match('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $file) === 1) {
$html .= '<div><img src="'.$this->context->link->getMediaLink(_THEME_CAT_DIR_.$file)
.'" alt="'.Tools::SafeOutput($category['name']).'" title="'
.Tools::SafeOutput($category['name']).'" class="imgm" /></div>';
