ecshop增長 瀏覽過該商品的人還瀏覽了那些商品 功能

這個 功能比較簡單 可是須要增長一個 數據表

1. 
   
2. CREATE TABLE `sc_history` (
   
3. `id` int(10) unsigned NOT NULL auto_increment,
   
4. `user_id` int(10) unsigned NOT NULL,
   
5. `goods_id` int(10) NOT NULL,
   
6. PRIMARY KEY (`id`)
   
7. ) ENGINE=MyISAM DEFAULT CHARSET=utf8;

複製代碼

首先在goods.php中找到

1. 
   
2. /*更新瀏覽歷史*/
   
3. $sql = 「select count(*) from 「.$GLOBALS['ecs']->table(‘history’).」 where goods_id=’$goods_id’」;
   
4. $num = $GLOBALS['db']->getOne($sql);
   
5. if(empty($num)){
   
6. $user_id = !empty($_SESSION['user_id'])?intval($_SESSION['user_id']):0;
   
7. $sql = 「insert into 「.$GLOBALS['ecs']->table(‘history’).」 (goods_id,user_id) values(‘$goods_id’,'$user_id’)」;
   
8. $GLOBALS['db']->query($sql);
   
9. }

複製代碼

將瀏覽的 商品放入 數據庫。
在 lib_insert中增長一個函數

1. 
   
2. insert_db_history()；
   
3. function insert_db_history()
   
4. {
   
5. $str = 」;
   
6. $res = array();
   
7. $sql = 「select goods_id from 「.$GLOBALS['ecs']->table(‘history’);
   
8. $res = $GLOBALS['db']->getAll($sql);
   
9. $ins = 」;
   
10. foreach($res as $key=>$val){
    
11. $ins .= $val['goods_id'].’,';
    
12. }
    
13. $ins = rtrim($ins,’,');
    
14. if (!empty($ins))
    
15. {
    
16. $where = db_create_in($ins, ‘goods_id’);
    
17. $sql = ‘SELECT goods_id, goods_name, goods_thumb, shop_price FROM ‘ . $GLOBALS['ecs']->table(‘goods’) .
    
18. 」 WHERE $where AND is_on_sale = 1 AND is_alone_sale = 1 AND is_delete = 0″;
    
19. $query = $GLOBALS['db']->query($sql);
    
20. $res = array();
    
21. while ($row = $GLOBALS['db']->fetch_array($query))
    
22. {
    
23. $goods['goods_id'] = $row['goods_id'];
    
24. $goods['goods_name'] = $row['goods_name'];
    
25. $goods['short_name'] = $GLOBALS['_CFG']['goods_name_length'] > 0 ? sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name'];
    
26. $goods['goods_thumb'] = get_image_path($row['goods_id'], $row['goods_thumb'], true);
    
27. $goods['shop_price'] = price_format($row['shop_price']);
    
28. $goods['url'] = build_uri(‘goods’, array(‘gid’=>$row['goods_id']), $row['goods_name']);
    
29. $res[] = $goods;
    
30. }
    
31. }
    
32. $GLOBALS['smarty']->assign(‘db_history’,$res);//
    
33. $output = $GLOBALS['smarty']->fetch(‘library/db_history.lbi’);
    
34. return $output;
    
35. }

複製代碼

在增長一個db_history.lbi就完成了 全部功能了。
若是你想添加到任何 頁面的話 值須要將{insert name=」db_history」}增長到你須要的位置就能夠了。
可是這個功能會致使你的數據表一直增長，因此適用於商品不是太多的 網站，若是商品多的話只要定時更新數據表便可。
