It seems many people is trying to make Wordpress and Yii work together. I got stuck with the same problem, but now I think I have achieved doing it, after a lot of hard thinking and many work hours spent.
When we use multiple radio buttons with same name in Yii
many people have the problem on getting the value of the selected radiobutton.
The radioButtonList can be used for that, but if we need to use radioButton itself to place the button any where in a view, we need to include one more parameter in htmloption array().
