OpenCart - 從產品查詢中刪除一個包含子類別的類別

我一直在努力改變getProducts($data = array())方法中的查詢。OpenCart - 從產品查詢中刪除一個包含子類別的類別

所以..在特定的控制器中，我添加了exclude_category_id => 65,$data數組，我將它傳遞給getProducts($data)。

$data = array(
    'sort' => 'p.date_added', 
    'order' => 'DESC', 
    'start' => 0, 
    'limit' => $setting['limit'], 
    'exclude_category_id' => 65 
);

在public function getProducts($data = array())model/catalog/product.php我加入這個代碼：

if (!empty($data['filter_category_id'])) { 
    if (!empty($data['filter_sub_category'])) { 
     $sql .= " FROM " . DB_PREFIX . "category_path cp LEFT JOIN " . DB_PREFIX . "product_to_category p2c ON (cp.category_id = p2c.category_id)";   
    } else { 
     $sql .= " FROM " . DB_PREFIX . "product_to_category p2c"; 
    } 

    if (!empty($data['filter_filter'])) { 
     $sql .= " LEFT JOIN " . DB_PREFIX . "product_filter pf ON (p2c.product_id = pf.product_id) LEFT JOIN " . DB_PREFIX . "product p ON (pf.product_id = p.product_id)"; 
    } else { 
     $sql .= " LEFT JOIN " . DB_PREFIX . "product p ON (p2c.product_id = p.product_id)"; 
    } 
} else if(!empty($data['exclude_category_id'])){ 

    // THIS ELSE IF IS ADDED BY ME 

    $sql .= " FROM " . DB_PREFIX . "product_to_category p2c"; 
    $sql .= " LEFT JOIN " . DB_PREFIX . "product p ON (p2c.product_id = p.product_id)"; 
}else { 
    $sql .= " FROM " . DB_PREFIX . "product p"; 
}

更深這種方法我還補充說：

if(!empty($data['exclude_category_id'])){ 
    $sql .= " AND p2c.category_id != '" . (int)$data['exclude_category_id'] . "'"; 
}

但是從類別產品ID = 65仍然可見。任何人有任何想法如何做到這一點？

這適用於主要產品類別，但不適用於產品具有該主要類別的子類別 – rgwsk65 2014-10-30 12:28:03

我解決了我的問題。在此功能

public function getProducts($data = array()) { 
    $exclude_ids; 

    if(!empty($data['exclude_category_id'])){ 
     $exclude_ids = array($data['exclude_category_id']); 

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

     $results = $this->model_catalog_category->getCategories($data['exclude_category_id']); 

     if($results){ 
      foreach($results as $result){ 
       $exclude_ids[] = $result['category_id']; 
      } 
     } 
    } 

    if(!empty($exclude_ids)){ 
     $t = $exclude_ids; 
     $exclude_ids = ""; 

     foreach($t as $id){ 
      $exclude_ids .= $id.', '; 
     } 

     $exclude_ids = substr($exclude_ids, 0, -2); 
    }

，更深：

我的方法開始加入model/catalog/product.php

if (!empty($data['filter_category_id'])) { 
     if (!empty($data['filter_sub_category'])) { 
      $sql .= " FROM " . DB_PREFIX . "category_path cp LEFT JOIN " . DB_PREFIX . "product_to_category p2c ON (cp.category_id = p2c.category_id)";   
     } else { 
      $sql .= " FROM " . DB_PREFIX . "product_to_category p2c"; 
     } 

     if (!empty($data['filter_filter'])) { 
      $sql .= " LEFT JOIN " . DB_PREFIX . "product_filter pf ON (p2c.product_id = pf.product_id) LEFT JOIN " . DB_PREFIX . "product p ON (pf.product_id = p.product_id)"; 
     } else { 
      $sql .= " LEFT JOIN " . DB_PREFIX . "product p ON (p2c.product_id = p.product_id)"; 
     } 
    } else if(!empty($data['exclude_category_id'])){ /*********** ADDED ELSE IF *********/ 
     $sql .= " FROM " . DB_PREFIX . "product_to_category p2c"; 
     $sql .= " LEFT JOIN " . DB_PREFIX . "product p ON (p2c.product_id = p.product_id)"; 
    }else { 
     $sql .= " FROM " . DB_PREFIX . "product p"; 
    }

而且更深一點：

if(!empty($data['exclude_category_id'])){ 
     $sql .= " AND p2c.category_id NOT IN (".$exclude_ids.")"; 
    }

對不起，混亂的解決方案，但時間是這個項目的關鍵。
