1、加红的提交设置该怎么实现呢？而且提交后更新的好像是一张隐式表；
2、第一版运行后，点击保存设置，在控制台有这样的一段信息，其中红色部分好像为更新的数据，我看不懂：
SELECT * FROM jchome_session WHERE uid=217
SELECT sf.*, s.* FROM jchome_space s LEFT JOIN jchome_spacefield sf ON sf.uid=s.uid WHERE s.uid='217'
tpl:/template/default/cp_privacy.jsp
SELECT * FROM jchome_session WHERE uid=217
SELECT sf.*, s.* FROM jchome_space s LEFT JOIN jchome_spacefield sf ON sf.uid=s.uid WHERE s.uid='217'
UPDATE jchome_spacefield SET `privacy`='a:2:{s:4:\"feed\";a:9:{s:6:\"invite\";i:1;s:4:\"post\";i:1;s:4:\"mtag\";i:1;s:6:\"thread\";i:1;s:5:\"click\";i:1;s:7:\"comment\";i:1;s:4:\"blog\";i:1;s:6:\"friend\";i:1;s:7:\"profile\";i:1;}s:4:\"view\";a:6:{s:5:\"index\";i:0;s:4:\"mtag\";i:0;s:5:\"doing\";i:0;s:4:\"blog\";i:0;s:4:\"wall\";i:0;s:6:\"friend\";i:0;}}' WHERE `uid`='217'
