I tried all the steps other similar previous questions but it didnt worked. I want to get 3rd level sub category in Top menu Opencart v2.3
以下代码是2levelcategory,我需要创建3级别类别。
这是header.php文件代码
This below code is of 2levelcategory, I need to create 3level category. This is the header.php file code
$categories = $this->model_catalog_category->getCategories(0);
foreach ($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'])
);
}

这是header.tpl文件代码
This is the header.tpl file code
<ul class="nav navbar-nav">
<?php foreach ($categories as $category) { ?>
<?php if ($category['children']) { ?>
<li class="dropdown"><a href="<?php echo $category['href']; ?>" class="dropdown-toggle" data-toggle="dropdown"><?php echo $category['name']; ?></a>
<div class="dropdown-menu">
<div class="dropdown-inner">
<?php foreach (array_chunk($category['children'], ceil(count($category['children']) / $category['column'])) as $children) { ?>
<ul class="list-unstyled">
<?php foreach ($children as $child) { ?>
<li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a></li>
<?php } ?>
</ul>
<?php } ?>
</div>
<a href="<?php echo $category['href']; ?>" class="see-all"><?php echo $text_all; ?> <?php echo $category['name']; ?></a> </div>
</li>
<?php } else { ?>
<li><a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a></li>
<?php } ?>
<?php } ?>
</ul>
推荐答案
您可以像这样添加第三层类别:
控制器文件:
You can Add 3rd level of categories like this: controller file:
$categories = $this->model_catalog_category->getCategories(0);
foreach ($categories as $category) {
if ($category['top']) {
// Level 2
$children_data = array();
$children = $this->model_catalog_category->getCategories($category['category_id']);
foreach ($children as $child) {
// Level 3
$grandchildren_data = array();
$grandchildren = $this->model_catalog_category->getCategories($child['category_id']);
foreach ($grandchildren as $grandchild) {
$grandchild_filter_data = array(
'filter_category_id' => $grandchild['category_id'],
'filter_sub_category' => true
);
$grandchildren_data[] = array(
'name' => $grandchild['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($grandchild_filter_data) . ')' : ''),
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $grandchild['category_id'])
);
}
$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']),
'children' => $grandchildren_data,
);
}
// Level 1
$data['categories'][] = array(
'name' => $category['name'],
'children' => $children_data,
'column' => $category['column'] ? $category['column'] : 1,
'href' => $this->url->link('product/category', 'path=' . $category['category_id'])
);
}
}
查看文件:
view file:
<ul class="nav navbar-nav">
<?php foreach ($categories as $category) { ?>
<?php if ($category['children']) { ?>
<li class="dropdown"><a href="<?php echo $category['href']; ?>" class="dropdown-toggle" data-toggle="dropdown"><?php echo $category['name']; ?></a>
<div class="dropdown-menu">
<div class="dropdown-inner">
<?php foreach (array_chunk($category['children'], ceil(count($category['children']) / $category['column'])) as $children) { ?>
<ul class="list-unstyled">
<?php foreach ($children as $child) { ?>
<li>
<a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a>
<?php if($child['children']){ ?>
<ul>
<?php foreach ($child['children'] as $child) { ?>
<li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a></li>
<?php } ?>
</ul>
<?php } ?>
</li>
<?php } ?>
</ul>
<?php } ?>
</div>
<a href="<?php echo $category['href']; ?>" class="see-all"><?php echo $text_all; ?> <?php echo $category['name']; ?></a> </div>
</li>
<?php } else { ?>
<li><a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a></li>
<?php } ?>
<?php } ?>
</ul>
