OpenCart 2：默認顯示類別模塊中的所有子類別（php）

真的需要您的幫助來完成此項工作。我使用的是OpenCart 2.0.3.1，我希望側邊欄類別模塊默認顯示所有類別的所有子類別。目前，只有當您點擊某個類別並且僅顯示該類別的子類別時，該模塊纔會顯示子類別。您可以在動作看看它：OpenCart 2：默認顯示類別模塊中的所有子類別（php）

http://demo.opencart.com/index.php?route=product/category&path=20

（它是在左側邊欄的模塊）

我只使用默認的模塊。我嘗試了許多不同的方式來完成這項工作，並沒有什麼幫助實現這一點。我知道我需要編輯這兩個文件：目錄/控制器/模塊/ category.php

<?php 
 
class ControllerModuleCategory extends Controller { 
 
\t public function index() { 
 
\t \t $this->load->language('module/category'); 
 

 
\t \t $data['heading_title'] = $this->language->get('heading_title'); 
 

 
\t \t if (isset($this->request->get['path'])) { 
 
\t \t \t $parts = explode('_', (string)$this->request->get['path']); 
 
\t \t } else { 
 
\t \t \t $parts = array(); 
 
\t \t } 
 

 
\t \t if (isset($parts[0])) { 
 
\t \t \t $data['category_id'] = $parts[0];

你希望它顯示它們展開並且默認情況下不折疊？ – timothymarois

是的，我希望默認擴展模塊並顯示每個類別的所有子類別。雖然你的解決方案似乎不起作用。你可以看看我的網站： http://test.vga.lt/ –

你確定你修改了正確的文件嗎？您的主題已從默認設置修改。但就我的代碼而言，我測試了我的本地版本，並且只列出了所有類別和子類別。它們防止它在控制器和視圖中發生。只要你注意到這些線，它應該顯示。 – timothymarois

在這裏，如果我正確地得到您的問題，您希望在頁面上自動顯示所有子類別，而不是僅顯示當前頁面類別的子類別。

複製這些代碼到系統

正如您在文件中看到的那樣，我在中指出了這些語句會阻止子類別在默認情況下顯示。

謝謝，這也是我的子類別問題的解決方案。 –
