下面提供一個PHP的無限分級類代碼,想要實現無限分級類的朋友們可以試試。Bug已經檢查修正過,直接復制代碼就能使用尖括號需要替換一下)。
1、數據庫ProductShow中有b_mtype表,建表語句如下:
- CREATE TABLE `b_mtype` (
- `typeid` int(4) NOT NULL default '0',
- `typename` varchar(50) NOT NULL default '',
- `parentid` int(4) NOT NULL default '0',
- `parentstr` varchar(200) NOT NULL default '',
- `depth` int(4) NOT NULL default '0',
- `rootid` int(4) NOT NULL default '0',
- `child` varchar(200) NOT NULL default '',
- `orders` varchar(200) NOT NULL default '',
- PRIMARY KEY (`typeid`)
- ) TYPE=MyISAM;
2、ProductClass.php代碼:直接復制即可)
