yii - difference between radioButtonList and activeRadioButtonList

in the yii framework

what is the difference between radioButtonList and activ开发者_开发技巧eRadioButtonList?

In Yii there is a "regular" and "active" version of (almost?) every CHtml form field helper/widget. With the "active" version you pass in the ActiveRecord Model and the Attribute you want to make a form field for. This ties the ActiveRecord model more closely to the form field which helps with a few things like:

1. applying the model->attribute's validation rules (especially ajax validation)
2. building the proper form $_POST structure for model->attribute assignments
3. getting the proper field label
4. etc

Use activeRadioButtonList if you are building a form for an ActiveRecord model, and use radioButtonList if you are building a regular form (for a CFormModel model).
