Warning: mysql_db_query is deprecated; use mysql_select_db() and mysql_query() instead in E:\phpadmin\tbl_properties.php3 on line 18警告：反对使用mysql_db_query，用mysql_select_db()和mysql_query()反对使用的原因： mysql_db_query() selects a database and executes a query on it. If the optional link identifier isn't specified, the function will try to find an open link to the MySQL server and if no such link is found it'll try to create one as if mysql_connect() was called with no arguments. 所以它会试图打开一个存在甚至自行连接数据库以得到一个link identifier。所以，一般不要用 关于第二个问题：提示你说nei这个常量没有附值，让你在manage3.php第5行中附值。试试LeeMaRS(小菜虎_水壶的仇人) (的建议
