如何在OpenCart 2中顯示某個類別的項目？

Question

我需要在OpenCart 2的主頁上顯示某個類別的項目。我該怎麼做？ 從控制器我的代碼：

$products_info = $this->model_catalog_product->getProducts(); 
    $data['products'] = $products_info;

假設你第一次加載你調用模型：

$this->load->model('catalog/product'); 

所有你需要做的就是定義設置的陣列傳遞給getProducts()。在這種情況下，你可以逃脫只發送你想獲得產品的類別ID：

$filter_data = array(
    'filter_category_id' => $category_id, 
); 

然後調用函數像你一樣：

$results = $this->model_catalog_product->getProducts($filter_data); 

然後遍歷產品，就好像你是在一個類別viewto數據傳遞給視圖：

foreach ($results as $result) { 
    if ($result['image']) { 
     $image = $this->model_tool_image->resize($result['image'], $this->config->get('config_image_product_width'), $this->config->get('config_image_product_height')); 
    } else { 
     $image = $this->model_tool_image->resize('placeholder.png', $this->config->get('config_image_product_width'), $this->config->get('config_image_product_height')); 
    } 

    if (($this->config->get('config_customer_price') && $this->customer->isLogged()) || !$this->config->get('config_customer_price')) { 
     $price = $this->currency->format($this->tax->calculate($result['price'], $result['tax_class_id'], $this->config->get('config_tax'))); 
    } else { 
     $price = false; 
    } 

    if ((float)$result['special']) { 
     $special = $this->currency->format($this->tax->calculate($result['special'], $result['tax_class_id'], $this->config->get('config_tax'))); 
    } else { 
     $special = false; 
    } 

    if ($this->config->get('config_tax')) { 
     $tax = $this->currency->format((float)$result['special'] ? $result['special'] : $result['price']); 
    } else { 
     $tax = false; 
    } 

    if ($this->config->get('config_review_status')) { 
     $rating = (int)$result['rating']; 
    } else { 
     $rating = false; 
    } 

    $data['products'][] = array(
     'product_id' => $result['product_id'], 
     'thumb'  => $image, 
     'name'  => $result['name'], 
     'description' => utf8_substr(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8')), 0, $this->config->get('config_product_description_length')) . '..', 
     'price'  => $price, 
     'special'  => $special, 
     'tax'   => $tax, 
     'minimum'  => $result['minimum'] > 0 ? $result['minimum'] : 1, 
     'rating'  => $result['rating'], 
     'href'  => $this->url->link('product/product', 'path=' . $this->request->get['path'] . '&product_id=' . $result['product_id'] . $url) 
    ); 
} 

現在你有一系列的產品來顯示，但是你會在你的TPL喜歡。
