我也是头一次接触它，做了个模板，但是一循环显示商品就抱错，而且只能显示一个不能循环，请大家帮我看看那里的错误啊？
[php]
<?
require('pre_inc.php');
$char_sql="select*from shop order by id desc";
$result=@mysql_db_query($db_name,$char_sql,$link_message);
$rows_number=@mysql_num_rows($result);
echo $rows_number;
for($i=0;$i<$rows_number;$i++){
$record=@mysql_fetch_object($result);

require('smarty/libs/smarty.class.php');
//生成$smarty实例
$smarty=new smarty;

//指定功能目录
$smarty->template_dir="smarty/templates";
$smarty->compile_dir="smarty/templates_c";
$smarty->config_dir="smarty/configs/";
$smarty->cache_dir="smarty/cache/";
//为模板变量赋值
$smarty->assign('tupian',$record->attachment);
$smarty->assign('jianjie',$record->productname);
$smarty->assign('name','机箱在线');

//显示模板
$smarty->display('zhanshi.tpl');
}
?>
[/php]

出现这个！
