ecshop根据标签(关键字)调用商品

1.打开/includes/lib_goods.php文件里加上这段:
function get_keyword_goods($keyword = '')
{
    $time = gmtime();
    $order_type = $GLOBALS['_CFG']['recommend_order'];
    $sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' .
            "INULLmp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
            "promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, goods_img, b.brand_name, " .
            "g.is_best, g.is_new, g.is_hot, g.is_promote, RAND() AS rnd " .
            'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' .
            'LEFT JOIN ' . $GLOBALS['ecs']->table('brand') . ' AS b ON b.brand_id = g.brand_id ' .
            "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 g.keywords LIKE '%$keyword%' " ;
    $sql .= $order_type == 0 ? ' ORDER BY g.sort_order, g.last_update DESC' : ' ORDER BY rnd';
    $result = $GLOBALS['db']->getAll($sql);
    $goods = array();
    foreach ($result 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]['brand_name']   = $row['brand_name'];
        $goods[$idx]['goods_style_name']   = add_style($row['goods_name'],$row['goods_name_style']);
        $goods[$idx]['short_name']   = $GLOBALS['_CFG']['goods_name_length'] > 0 ? sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name'];
        $goods[$idx]['short_style_name']   = add_style($goods[$idx]['short_name'],$row['goods_name_style']);
        $goods[$idx]['market_price'] = price_format($row['market_price']);
        $goods[$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;
}
2.在需要调用商品的页面php文件(一般是index.php)里在 assign_dynamic('index'); 之前写上这段
$smarty->assign( 'ecshop_cx',      get_keyword_goods('商城首页'));
其中,商城首页是我在商品的“其他信息”-“商品关键词”一栏中填写的用于调用的关键词
3. 在需要调用商品的dwt或lbi中用foreach就可以调啦
<!--{foreach from=$ecshop_cx item=goods}-->
<!--{/foreach}-->
