按组查看信息

Question

我在prestashop之下开发了一个站点，并且在一件事情上受阻。我在prestashop中添加了为供应商选择组的可能性。每个用户都吸引1个或多个组，而我尝试仅显示他们在同一组中共有的供应商。

我已经创建了一个vendor_group表，所以到目前为止，我必须将每个提供程序修补到一个或多个组。但是，当我与要加入A组的用户在一起时，我只需要看到同时也是A组的拉手的提供商，这就是我遇到的问题。

我想修改此显示，我想我可以通过以下功能来做到这一点：

public static function getSuppliers($get_nb_products = false, $id_lang = 0, $active = true, $p = false, $n = false, $all_groups = false)
{
    if (!$id_lang) {
        $id_lang = Configuration::get('PS_LANG_DEFAULT');
    }
    if (!Group::isFeatureActive()) {
        $all_groups = true;
    }

    $query = new DbQuery();
    $query->select('s.*, sl.`description`');
    $query->from('supplier', 's');
    $query->leftJoin('supplier_lang', 'sl', 's.`id_supplier` = sl.`id_supplier` AND sl.`id_lang` = '.(int)$id_lang);
    $query->join(Shop::addSqlAssociation('supplier', 's'));
    if ($active) {
        $query->where('s.`active` = 1');
    }
    $query->orderBy(' s.`name` ASC');
    $query->limit($n, ($p - 1) * $n);
    $query->groupBy('s.id_supplier');

    $suppliers = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS($query);
    if ($suppliers === false) {
        return false;
    }
    if ($get_nb_products) {
        $sql_groups = '';
        if (!$all_groups) {
            $groups = FrontController::getCurrentCustomerGroups();
            $sql_groups = (count($groups) ? 'IN ('.implode(',', $groups).')' : '= 1');
        }

        $results = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS('
                SELECT  ps.`id_supplier`, COUNT(DISTINCT ps.`id_product`) as nb_products
                FROM `'._DB_PREFIX_.'product_supplier` ps
                JOIN `'._DB_PREFIX_.'product` p ON (ps.`id_product`= p.`id_product`)
                '.Shop::addSqlAssociation('product', 'p').'
                LEFT JOIN `'._DB_PREFIX_.'supplier` as m ON (m.`id_supplier`= p.`id_supplier`)
                WHERE ps.id_product_attribute = 0'.
            ($active ? ' AND product_shop.`active` = 1' : '').
            ' AND product_shop.`visibility` NOT IN ("none")'.
            ($all_groups ? '' :'
                AND ps.`id_product` IN (
                    SELECT cp.`id_product`
                    FROM `'._DB_PREFIX_.'category_group` cg
                    LEFT JOIN `'._DB_PREFIX_.'category_product` cp ON (cp.`id_category` = cg.`id_category`)
                    WHERE cg.`id_group` '.$sql_groups.'
                )').'
                GROUP BY ps.`id_supplier`'
        );

        $counts = array();
        foreach ($results as $result) {
            $counts[(int)$result['id_supplier']] = (int)$result['nb_products'];
        }

        if (count($counts) && is_array($suppliers)) {
            foreach ($suppliers as $key => $supplier) {
                if (isset($counts[(int)$supplier['id_supplier']])) {
                    $suppliers[$key]['nb_products'] = $counts[(int)$supplier['id_supplier']];
                } else {
                    $suppliers[$key]['nb_products'] = 0;
                }
            }
        }
    }

    $nb_suppliers = count($suppliers);
    $rewrite_settings = (int)Configuration::get('PS_REWRITING_SETTINGS');
    for ($i = 0; $i < $nb_suppliers; $i++) {
        $suppliers[$i]['link_rewrite'] = ($rewrite_settings ? Tools::link_rewrite($suppliers[$i]['name']) : 0);
    }

    return $suppliers;
}

但是我不知道该怎么做。你有主意吗？

感谢您的帮助。
