更改OpenCart中的过滤行为

Question

我在我的商店使用OpenCart的默认过滤行为.过滤的工作方式,当您选择多个过滤器时,它会显示符合任何选定条件的任何产品.我需要更改此行为,以便它只显示符合所有选定条件的产品.

我已经缩小了负责任的职能范围 catalog/model/catalog/product.php

以下是整个功能.我有什么想法改变逻辑吗？

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

            if ($this->customer->isLogged()) {
                $customer_group_id = $this->customer->getCustomerGroupId();

                $customer_group_id = $this->config->get('config_customer_group_id');
            }   

            $sql = "SELECT p.product_id, (SELECT AVG(rating) AS total FROM " . DB_PREFIX .

如果要在同一组中的属性和不同组中的属性之间的AND逻辑之间具有OR逻辑,则应该:

转到"catalog\model\catalog"编辑product.php

您需要编辑的函数是公共函数getProducts($ data = array(),$ get_all = FALSE){

在函数的开头指定这些变量:$ validimi = false; $ filter_groups = array();

找到这个代码:

if (!empty($data['filter_filter'])) {
                $implode = array();

                $filters = explode(',', $data['filter_filter']);

                foreach ($filters as $filter_id) {
                    $implode[] = (int)$filter_id;
                }

                $sql .= " AND pf.filter_id IN (" . implode(',', $implode) . ")";
}

并在$ sql.="AND pf.filter_id IN(".implode(',',$ implode)之前添加这篇文章.")";

        $sql_check = "SELECT DISTINCT (filter_group_id) FROM  " . DB_PREFIX . "filter WHERE filter_id IN (" . implode(',', $implode) . ") ";    
        $query_check = $this->db->query($sql_check);
        $filter_groups = array();
        foreach ($query_check->rows as $result) {
            $filter_groups[$result['filter_group_id']] = array();
        }

        if(count($filter_groups) > 1){
            $validimi = true;               
        }else{
            $validimi = false;
        }

终于在我指定的函数中找到这段代码:

$ sql.="GROUP BY p.product_id";

并将其更改为:

  If( $validimi ) {
$sql .= "GROUP BY p.product_id HAVING COUNT( DISTINCT pf.filter_id)=".count($filter_groups);
}else{

    $sql .= " GROUP BY p.product_id";

}

现在尝试你的过滤器他们应该工作正常,这是我在我自己的商店创建和使用但使用opencart版本1.5.5.1,但我认为它也适用于你的情况.逻辑很清楚,以防这段代码对你没用,你可以用逻辑来创建自己的:).

希望我帮忙.
