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： $sql = “INSERT INTO `dede58_sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`,`father`) VALUES(‘$ename’,’$evalue’,’$egroup’,’$disorder’,’$issign’,’$father’); “; <?php /** * 联动选择管理 * * @version $Id: stepselect_main.php 2 13:23 2011-3-24 tianya $ * @package DedeCMS.Administrator * @copyright Copyright (c) 2007 – 2010, DesDev, Inc. * @license http://help.dedecms.com/usersguide/license.html * @link http://www.dedecms.com */ require_once(dirname(__FILE__).”/config.php”);
