YII中checkBoxList的数据库存取
checkBoxList是YII中的复选框组，用户在增加数据时，将以数组的形式把数据提交过来。但是，对应数据库的一个字段，只能保存字符串，不能保存数组。这时，我们可以先将提交过来的数组，用PHP的implode()，将数组转换成字符串，然后保存到数据库中。修改数据时，从数据库的一个字段中取出类似1，2，8，9的字符串，用explode()，重新将字符串转换成数组，在actionupdate()方法中，使用$model->goods_color的形式，将数据赋值给模型对应的属性，这时候，之前保存的值，将会被勾中。修改后的值，会重新再入库。效果如下：
1、增加商品
2、选择提交
3、提交后数据库显示的字符串
4、点击修改，表单又会从数据库将读出来的值对应到相应的值
以下是对应的代码：
控制器：
array('index','view'),
'users'=>array('*'),

array('allow', // allow authenticated user to perform 'create' and 'update' actions
'actions'=>array('create','update'),
'users'=>array('@'),

array('allow', // allow admin user to perform 'admin' and 'delete' actions
'actions'=>array('admin','delete'),
'users'=>array('admin','@'),
),
array('deny', // deny all users
'users'=>array('*'),
),
);
