我正在寻找一种在站点地图页面上显示另一个类别的方法(默认情况下为3)。
我尝试使用以下代码修改模板的sitemap.twig
:
<li><a href="{{ category_3.href }}">{{ category_3.name }}</a>
{% if category_3.children %}
<ul>
{% for category_4 in category_3.children %}
<li><a href="{{ category_4.href }}">{{ category_4.name }}</a></li>
{% endfor %}
</ul>
{% endif %}
</li>
但它没有用。
然后我还尝试将/catalog/controller/information/sitemap.php
更改为foreach
个周期:
foreach ($categories_3 as $category_3) {
$level_4_data = array();
$categories_4 = $this->model_catalog_category->getCategories($category_3['category_id']);
foreach ($categories_4 as $category_4) {
$level_4_data[] = array(
'name' => $category_4['name'],
'href' => $this->url->link('product/category', 'path=' . $category_1['category_id'] . '_' . $category_2['category_id'] . '_' . $category_3['category_id'] . '_' . $category_4['category_id'])
);
}
$level_3_data[] = array(
'name' => $category_3['name'],
'children' => $level_4_data,
'href' => $this->url->link('product/category', 'path=' . $category_1['category_id'] . '_' . $category_2['category_id'] . '_' . $category_3['category_id'])
);
}
一切都没发生。所以我问是否有办法解决我的问题?
答案 0 :(得分:1)
您可以这种方式显示所有类别及其子类别(类别树):
控制器文件:
catalog\controller\information\sitemap.php
在关闭}
protected $categoryTree = '';
protected function buildCategoryTree($parent_id = 0, $categories = null, $path = ''){
$categories = $this->model_catalog_category->getCategories($parent_id);
if($categories){
$this->categoryTree .= '<ul>';
foreach ($categories as $category) {
$path = $path ? $path . $category['category_id'] : $category['category_id'];
$href = $this->url->link('product/category', 'path=' . $path);
$categories = $this->model_catalog_category->getCategories($category['category_id']);
$this->categoryTree .= '<li><a href="' . $href . '">' . $category['name'] . '</a>';
$this->buildCategoryTree($category['category_id'], $categories, $path . '_');
$this->categoryTree .= '</li>';
}
$this->categoryTree .= '</ul>';
}
}
<强>查找强>
$this->response->setOutput($this->load->view('information/sitemap', $data));
在它之前添加:
$this->buildCategoryTree();
$data['categories'] = $this->categoryTree;
查看文件:
catalog\view\theme\*\template\information\sitemap.twig
<强>查找强>
<ul>
{% for category_1 in categories %}
<li><a href="{{ category_1.href }}">{{ category_1.name }}</a>
{% if category_1.children %}
<ul>
{% for category_2 in category_1.children %}
<li><a href="{{ category_2.href }}">{{ category_2.name }}</a>
{% if category_2.children %}
<ul>
{% for category_3 in category_2.children %}
<li><a href="{{ category_3.href }}">{{ category_3.name }}</a></li>
{% endfor %}
</ul>
{% endif %}
</li>
{% endfor %}
</ul>
{% endif %}
</li>
{% endfor %}
</ul>
将其替换为:
{{ categories }}
您可以删除控制器文件中的主要类别foreach
循环。
