Problems related to insertion in yii Framework

In the yii Framework, when a problem occurs, I assign a value to an attribute of the model in the controller, for example, $ model = new & nbsp; post; $ model-& gt; type = 1; what is used in my view ;? Php & nbsp; $ form = $ this-& gt; beginWidget ('cactiveform', & nbs yii Framework insertion error
I assign a value to a model attribute in the controller:
For example:
$ Model = new post;
$ Model-> type = 1;

In my view
BeginWidget ('cactiveform', array (
'Id' => 'china4a-reg-form ',
'Enableajaxvalidation '=> false,
));
This method is used to obtain the values of other fields.
The submission method is as follows:
IsNewRecord? 'Submit': 'save');?>

However, values in the widget can be correctly inserted into the database, but $ model-> type cannot be inserted.

I haven't tried it for a long time. how can I insert records for this field at the same time? You can also give some advice.

------ Solution --------------------
How do you know if your $ model is outside (maybe it is still inside the method) and you don't pass it?
------ Solution --------------------
Yes. Your $ model-> type needs to be submitted together with other content
