真的需要你的帮助才能完成这项工作。我使用的是OpenCart 2.0.3.1,我希望边栏类别模块默认情况下显示所有类别的所有子类别。目前,该模块仅在您单击一个类别时显示子类别,并且仅显示该类别的子类别。你可以看看它的实际效果:
http://demo.opencart.com/index.php?route=product/category&路径= 20
(左边栏的模块)
我只是使用默认模块。我尝试了许多不同的方法来获得这项工作,但没有任何方法可以帮助实现这一目标。我知道我需要编辑这两个文件:目录/控制器/模块/category.php
<?php
class ControllerModuleCategory extends Controller {
public function index() {
$this->load->language('module/category');
$data['heading_title'] = $this->language->get('heading_title');
if (isset($this->request->get['path'])) {
$parts = explode('_', (string)$this->request->get['path']);
} else {
$parts = array();
}
if (isset($parts[0])) {
$data['category_id'] = $parts[0];
} else {
$data['category_id'] = 0;
}
if (isset($parts[1])) {
$data['child_id'] = $parts[1];
} else {
$data['child_id'] = 0;
}
$this->load->model('catalog/category');
$this->load->model('catalog/product');
$data['categories'] = array();
$categories = $this->model_catalog_category->getCategories(0);
foreach ($categories as $category) {
$children_data = array();
if ($category['category_id'] == $data['category_id']) {
$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(
'category_id' => $child['category_id'],
'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'])
);
}
}
$filter_data = array(
'filter_category_id' => $category['category_id'],
'filter_sub_category' => true
);
$data['categories'][] = array(
'category_id' => $category['category_id'],

感谢任何帮助,欢呼声
在这里,如果我得到你的问题正确,你想在页面上自动显示所有的子类别,而不是只显示当前页面类别的子类别。
将这些代码复制到您的系统

正如您在文件中看到的那样,我指出了在默认情况下阻止子类别显示的语句。
