ecshop商品描述页上一个下一个alt怎么改为商品名称

步骤一：修改 goods.php文件找到下面这段代码

/* 上一个商品下一个商品 */
$prev_gid = $db->getOne("SELECT goods_id FROM " .$ecs->table('goods'). " WHERE cat_id=" . $goods['cat_id'] . " AND goods_id > " . $goods['goods_id'] . " AND is_on_sale = 1 AND is_alone_sale = 1 AND is_delete = 0 LIMIT 1");
if (!empty($prev_gid))
{
$prev_good['url'] = build_uri('goods', array('gid' => $prev_gid), $goods['goods_name']);
$smarty->assign('prev_good', $prev_good);//上一个商品
}
$next_gid = $db->getOne("SELECT max(goods_id) FROM " . $ecs->table('goods') . " WHERE cat_id=".$goods['cat_id']." AND goods_id < ".$goods['goods_id'] . " AND is_on_sale = 1 AND is_alone_sale = 1 AND is_delete = 0");
if (!empty($next_gid))
{
$next_good['url'] = build_uri('goods', array('gid' => $next_gid), $goods['goods_name']);
$smarty->assign('next_good', $next_good);//下一个商品
}

然后将它修改为下面代码（注意红的部分）

/* 上一个商品下一个商品 */
$prev_gid = $db->getRow("SELECT goods_id,goods_name FROM " .$ecs->table('goods'). " WHERE cat_id=" . $goods['cat_id'] . " AND goods_id > " . $goods['goods_id'] . " AND is_on_sale = 1 AND is_alone_sale = 1 AND is_delete = 0 LIMIT 1");
if (!empty($prev_gid))
{
$prev_good['url'] = build_uri('goods', array('gid' => $prev_gid['goods_id']), $goods['goods_name']);
$prev_good['goods_name'] =$prev_gid['goods_name'];
$smarty->assign('prev_good', $prev_good);//上一个商品
}
$next_gid = $db->getRow("SELECT goods_id,goods_name FROM " . $ecs->table('goods') . " WHERE cat_id=".$goods['cat_id']." AND goods_id < ".$goods['goods_id'] . " AND is_on_sale = 1 AND is_alone_sale = 1 AND is_delete = 0 order by goods_id desc limit 1");
if (!empty($next_gid))
{
$next_good['url'] = build_uri('goods', array('gid' => $next_gid['goods_id']), $goods['goods_name']);
$next_good['goods_name'] =$next_gid['goods_name'];
$smarty->assign('next_good', $next_good);//下一个商品
}

第2步： 修改模板文件  （以官方默认模板为例）  /themes/default/goods.dwt
将

<a href="{$prev_good.url}"><img alt="prev" src="./images/up.gif" /></a> 修改为：
<a href="{$prev_good.url}"><img alt="{$prev_good.goods_name}" src="./images/up.gif" /></a> 再将
<a href="{$next_good.url}"><img alt="next" src="./images/down.gif" /></a> 修改为
<a href="{$next_good.url}"><img alt="{$next_good.goods_name}" src="./images/down.gif" /></a>
