ecshop控制某些商品显示首页

      ecshop后台虽然在产品列表里面可以设置商品属于精品，新品，热卖几个类型。但是很多时候，我们在首页不但要展示这些商品，我们还可能需要人为的展现某些特被推荐的产品。而且很灵活的在ecshop商品列表的后台控制和选择某些商品是否属于特推商品。这样我们必须在ecshop商品数据库里面增加一字段is_index来控制。

   1:  首先我们给ecshop商品表增加一个字段is_index

    alter table ecs_goods add column is_index int(1) default 0;

   2:在商品列表中增加以下内容admin/templates/goods_list.htm

 <th><a href="javascript:listTable.sort('is_index'); ">首页推荐</th>
  

        <td align="center"><img src="images/{if $goods.is_index}yes{else}no{/if}.gif" onclick="listTable.toggle(this, 'toggle_is_index', {$goods.goods_id})" /></td>
   3: admin/goods.php中增加以下内容。

   elseif ($_REQUEST['act'] == 'toggle_is_index')
{
    check_authz_json('goods_manage');

    $goods_id       = intval($_POST['id']);
    $is_index        = intval($_POST['val']);

    if ($exc->edit("is_index = '$is_index', last_update=" .gmtime(), $goods_id))
    {
        clear_cache_files();
        make_json_result($is_index);
    }
}

    4:前台通过以下函数来调用数据

   function assign_is_index_goods( $num = 16)
{
   

    $sql = 'SELECT g.goods_id, g.goods_name, g.market_price, g.shop_price AS org_price, ' .
                "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
               'g.promote_price, promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' .
            "FROM " . $GLOBALS['ecs']->table('goods') . ' AS g '.
            "LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
                    "ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' ".
            'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.
                'g.is_delete = 0 AND is_index =1  ';

    $order_rule = empty($order_rule) ? 'ORDER BY g.sort_order, g.goods_id DESC' : $order_rule;
    $sql .= $order_rule;
    if ($num > 0)
    {
        $sql .= ' LIMIT ' . $num;
    }
    $res = $GLOBALS['db']->getAll($sql);

    $goods = array();
    foreach ($res AS $idx => $row)
    {
        if ($row['promote_price'] > 0)
        {
            $promote_price = bargain_price($row['promote_price'], $row['promote_start_date'], $row['promote_end_date']);
            $goods[$idx]['promote_price'] = $promote_price > 0 ? price_format($promote_price) : '';
        }
        else
        {
            $goods[$idx]['promote_price'] = '';
        }

        $goods[$idx]['id']           = $row['goods_id'];
        $goods[$idx]['name']         = $row['goods_name'];
        $goods[$idx]['brief']        = $row['goods_brief'];
        $goods[$idx]['market_price'] = price_format($row['market_price']);
        $goods[$idx]['short_name']   = $GLOBALS['_CFG']['goods_name_length'] > 0 ?
                                        sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name'];
        $goods[$idx]['shop_price']   = price_format($row['shop_price']);
        $goods[$idx]['thumb']        = get_image_path($row['goods_id'], $row['goods_thumb'], true);
        $goods[$idx]['goods_img']    = get_image_path($row['goods_id'], $row['goods_img']);
        $goods[$idx]['url']          = build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);
    }

    return $goods;
}

   以上就完成了ecshop控制某些商品显示首页
