首页调单个产品分类的推荐产品，最新产品和热卖商品
在index.php文件里面有一段代码就是获得推荐产品，最新产品和热卖商品的，但是那是对所有分类而言的。其实要调单个分类呢，很简单，$act = !empty($_GET['act']) ? $_GET['act'] : '';在这句话下面的那段代码里面有个函数是获得产品分类ID的get_children($cat_id);调单个产品分类就把里面的变量换成你要调的相应的分类ID就行了。具体的实现如下代码：
$my_cat_rec_goods=array();//定义一个函数 $children=get_children(87);//获得分类ID $my_cat_rec_goods[87]=get_category_recommend_goods('best', $children);//调取该分类下的推荐产品
呵呵，其实这个很简单的啦，这个是在同事那里学来的。。
然后呢说说首页调产品评论（必须显示产品的所有信息）
这个呢也是很简单的啦。。在message.php这个文件里面有个function get_msg_list($num, $start)函数，这个函数的作用是。。先把这个函数考到首页（index.php）文件下面。为了得到产品的所有信息就要对函数做一点小修改，先找到$msg[$rows['msg_time']]['id_value'] = $rows['id_value'];这句代码，在下面加一句代码$msg[$rows['msg_time']]['goods_info'] = $goods_res（这句代码的作用就是获得产品的详细信息）;然后把下面的代码去掉（因为下面的代码是获得产品的名称和连接地址的）。其实我只需要调的是评论部分，所以这个函数里面有很多都可以删掉。修改后的代码如下：
function get_msg_list($num, $start) { /* 获取留言数据 */ $msg = array(); $sql = "(SELECT 'comment' AS tablename, comment_id AS ID, content AS msg_content, null AS msg_title, add_time AS msg_time, id_value AS id_value, comment_rank AS comment_rank, null AS message_img, user_name AS user_name, '6' AS msg_type "; $sql .= " FROM " .$GLOBALS['ecs']->table('comment'); $sql .= "WHERE STATUS =1 AND comment_type =0) "; $sql .= " UNION "; $sql .= "(SELECT 'feedback' AS tablename, msg_id AS ID, msg_content AS msg_content, msg_title AS msg_title, msg_time AS msg_time, null AS id_value, null AS comment_rank, message_img AS message_img, user_name AS user_name, msg_type AS msg_type "; $sql .= " FROM " .$GLOBALS['ecs']->table('feedback'); $sql .= " WHERE `msg_area`='1' AND `msg_status` = '1') "; $sql .= " ORDER BY msg_time DESC "; $res = $GLOBALS['db']->SelectLimit($sql, $num, $start); while ($rows = $GLOBALS['db']->fetchRow($res)) { for($i = 0; $i < count($rows); $i++) { $msg[$rows['msg_time']]['user_name'] = htmlspecialchars($rows['user_name']); $msg[$rows['msg_time']]['msg_content'] = str_replace('\r\n', '<br />', htmlspecialchars($rows['msg_content'])); $msg[$rows['msg_time']]['msg_content'] = str_replace('\n', '<br />', $msg[$rows['msg_time']]['msg_content']); $msg[$rows['msg_time']]['msg_time'] = local_date($GLOBALS['_CFG']['time_format'], $rows['msg_time']); $msg[$rows['msg_time']]['msg_type'] = $GLOBALS['_LANG']['message_type'][$rows['msg_type']]; $msg[$rows['msg_time']]['msg_title'] = nl2br(htmlspecialchars($rows['msg_title'])); $msg[$rows['msg_time']]['message_img'] = $rows['message_img']; $msg[$rows['msg_time']]['tablename'] = $rows['tablename']; if(isset($rows['order_id'])) { $msg[$rows['msg_time']]['order_id'] = $rows['order_id']; } $msg[$rows['msg_time']]['comment_rank'] = $rows['comment_rank']; $msg[$rows['msg_time']]['id_value'] = $rows['id_value']; /*如果id_value为true为商品评论,根据商品id取出商品名称*/ if($rows['id_value']) { $sql_goods = "SELECT * FROM ".$GLOBALS['ecs']->table('goods'); $sql_goods .= "WHERE goods_id= ".$rows['id_value']; $goods_res = $GLOBALS['db']->getRow($sql_goods); $msg[$rows['msg_time']]['goods_info'] = $goods_res;//获得商品的详细信息 } } $msg[$rows['msg_time']]['tablename'] = $rows['tablename']; $id = $rows['ID']; $reply = array(); if(isset($msg[$rows['msg_time']]['tablename'])) { $table_name = $msg[$rows['msg_time']]['tablename']; if ($table_name == 'feedback') { $sql = "SELECT user_name AS re_name, user_email AS re_email, msg_time AS re_time, msg_content AS re_content ,parent_id". " FROM " .$GLOBALS['ecs']->table('feedback') . " WHERE parent_id = '" . $id. "'"; } else { $sql = 'SELECT user_name AS re_name, email AS re_email, add_time AS re_time, content AS re_content ,parent_id FROM ' . $GLOBALS['ecs']->table('comment') . " WHERE parent_id = $id "; } $reply = $GLOBALS['db']->getRow($sql); if ($reply) { $msg[$rows['msg_time']]['re_name'] = $reply['re_name']; $msg[$rows['msg_time']]['re_email'] = $reply['re_email']; $msg[$rows['msg_time']]['re_time'] = local_date($GLOBALS['_CFG']['time_format'], $reply['re_time']); $msg[$rows['msg_time']]['re_content'] = nl2br(htmlspecialchars($reply['re_content'])); } } } return $msg; }
调评论的部分呢就结束了，其实我也不知道我的这个对不对，不过我能调出来哦。希望能帮到你们吧！
下面呢我来说说调单个文章分类的最新文章这个是我在网上找到的，然后就把它一起放在这里了
/** * 获得指定栏目最新的文章列表。 * * @access private * @return array */ function index_get_class_articles($cat_aid, $cat_num) { $sql = "SELECT article_id, title,open_type,cat_id,file_url FROM " .$GLOBALS['ecs']->table('article'). " WHERE cat_id = ".$cat_aid." and is_open = 1 LIMIT " . $cat_num; $res = $GLOBALS['db']->getAll($sql); $arr = array(); foreach ($res AS $idx => $row) { $arr[$idx]['id'] = $row['article_id']; $arr[$idx]['title'] = $row['title']; $arr[$idx]['short_title'] = $GLOBALS['_CFG']['article_title_length'] > 0 ? sub_str($row['title'], $GLOBALS['_CFG']['article_title_length']) : $row['title']; $arr[$idx]['cat_name'] = $row['cat_name']; $arr[$idx]['add_time'] = local_date($GLOBALS['_CFG']['date_format'], $row['add_time']); $arr[$idx]['url'] = $row['open_type'] != 1 ?build_uri('article', array('aid' => $row['article_id']), $row['title']) : trim($row['file_url']); $arr[$idx]['cat_url'] = build_uri('article_cat', array('acid' => $row['cat_id'])); } return $arr; }
然后再在这句代码下面加上这句话
$smarty->assign('new_articles', index_get_new_articles()); // 最新文章
模版里面怎么用大家应该知道吧，这里就不多说了！
评论框那里有个等级的选择，如果为了样式的好看要去掉，最简单的方法就是把它隐藏。
