让dedecms联动模型支持dede_sys_enum的father字段自动追加

对dede_sys_enum添加father字段,实现目的:在添加联动分类时,自动添加father的值。以500为分类界限。即:503的父类(father)为503,1001的father为1000。
主要修改的文件 stepselect_main.php文件。
解决: 修改有三处。
1.主要添加内容:
$father = intval(floor($evalue/500))*500;  
2.修改内容:
$sql = “INSERT INTO `zuimoban_sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`,`father`)
                             VALUES(‘$ename’,’$evalue’,’$egroup’,’$disorder’,’$issign’,’$father’); “;

function __addenum_save() { }
关于二级枚举的说明,为了节省查询速度,二级枚举是通过特殊算法生成的,原理为
凡是能被 500 整除的都是一级枚举,(500 * n) + 1 < em < 500 * (n+1) 为下级枚举
如:1000 的下级枚举对应的值为 1001,1002,1003…1499
对于 issign=1 的,表示这个类别只有一级枚举,则不受上面的算法限制
————————————————————————
更新算法:
新增二级枚举下添加”-N”自己类别选择,例如:
1001二级枚举下面的3级类目,则为1001-1,1001-2…
这时候需要issign=2
