修改article.php文件

if(isset($article) && $article['cat_id'] > 2)
{
$smarty->display('article.dwt', $cache_id);
}
else
{
$smarty->display('article_pro.dwt', $cache_id);
}

改成如下

if(isset($article) && $article['cat_id'] > 2)
{
$smarty->display('article.dwt');
}
elseif(isset($article) && $article['cat_id'] == 17)
{
$smarty->display('article_news.dwt');
}
else
{
$smarty->display('article_pro.dwt');
}
