我有这样的类别:下拉菜单中的category> sub1> sub2 sub2不可扩展。
我必须单击sub1才能看到sub2。如何解决这个问题?
我的opencart版本是3.0.2
在OpenCart中,主菜单仅显示2个级别。顶级和次级。第二个子级别不会显示。你需要自己开发它。
你可以在catalog/controller/common/menu.php
找到菜单逻辑的代码
foreach ($categories as $category) {
if ($category['top']) {
// Level 2
$children_data = array();
$children = $this->model_catalog_category->getCategories($category['category_id']);
foreach ($children as $child) {
$filter_data = array(
'filter_category_id' => $child['category_id'],
'filter_sub_category' => true
);
$children_data[] = array(
'name' => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'])
);
}
// Level 1
$data['categories'][] = array(
'name' => $category['name'],
'children' => $children_data,
'column' => $category['column'] ? $category['column'] : 1,
'href' => $this->url->link('product/category', 'path=' . $category['category_id'])
);
}
}
因为你只能看到2个级别。您可以添加代码以类似的方式扩展第二级,包括它也作为1级子级的一部分。
foreach ($categories as $category) {
if ($category['top']) {
// Level 2
$children_data = array();
$children = $this->model_catalog_category->getCategories($category['category_id']);
foreach ($children as $child) {
$filter_data = array(
'filter_category_id' => $child['category_id'],
'filter_sub_category' => true
);
$children_data[] = array(
'name' => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'])
);
//level 3
$children2 = $this->model_catalog_category->getCategories($child['category_id']);
foreach ($children2 as $child2) {
$filter_data = array(
'filter_category_id' => $child2['category_id'],
'filter_sub_category' => true
);
//adding everything to the second level
$children_data[] = array(
'name' => $child2['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'] . '_' .$child2['category_id'])
);
}
}
// Level 1
$data['categories'][] = array(
'name' => $category['name'],
'children' => $children_data,
'column' => $category['column'] ? $category['column'] : 1,
'href' => $this->url->link('product/category', 'path=' . $category['category_id'])
);
}
}
或者您可以将子项添加到第二级作为第三级,然后在twig文件中添加用于显示第二级子项的代码。
foreach ($categories as $category) {
if ($category['top']) {
// Level 2
$children_data = array();
$children = $this->model_catalog_category->getCategories($category['category_id']);
foreach ($children as $child) {
$filter_data = array(
'filter_category_id' => $child['category_id'],
'filter_sub_category' => true
);
//level 3
$children_data2 = array();
$children2 = $this->model_catalog_category->getCategories($child['category_id']);
foreach ($children2 as $child2) {
$filter_data = array(
'filter_category_id' => $child2['category_id'],
'filter_sub_category' => true
);
$children_data2[] = array(
'name' => $child2['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'] . '_' .$child2['category_id'])
);
}
$children_data[] = array(
'name' => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id']),
'children' => $children_data2
);
}
// Level 1
$data['categories'][] = array(
'name' => $category['name'],
'children' => $children_data,
'column' => $category['column'] ? $category['column'] : 1,
'href' => $this->url->link('product/category', 'path=' . $category['category_id'])
);
}
}
并在twig文件中catalog/view/theme/default/template/common/menu.twig
在line 16
上替换此代码
<li><a href="{{ child.href }}">{{ child.name }}</a></li>
有了这个
<li><a href="{{ child.href }}">{{ child.name }}</a>
{% for child2 in child['children'] %}
<li><a class="small" href="{{ child2.href }}"> > {{ child2.name }}</a></li>
{% endfor %}
</li>
