php - magento 以编程方式构建类别树

Question

我想将类别树添加到选择多个选项控件中

我搜索了很多 this link

但它以 ul li 结构给我输出如下

但是我想把这个树结构变成select multiple options

任何人都知道如何更改链接代码吗

准备数组:

public function getCategoriesArray() {

    $categoriesArray = Mage::getModel('catalog/category')
            ->getCollection()
            ->addAttributeToSelect('name')
            ->addAttributeToSort('path', 'asc')
            ->load()
            ->toArray();

    $categories = array();
    foreach ($categoriesArray as $categoryId => $category) {
        if (isset($category['name']) && isset($category['level'])) {
            $categories[] = array(
                'label' => $category['name'],
                'level'  =>$category['level'],
                'value' => $categoryId
            );
        }
    }

    return $categories;
}

以形式显示:

    $fieldset->addField('categories', 'multiselect', array(
        'label' => $this->__('Categories'),
        'name' => 'categories',
        'values' => Mage::getModel(...)->getCategoriesArray(),
    ));
