when we use multiple radio buttons with same name in Yii many people have the problem on getting the value of the selected radiobutton. we can use radioButtonList for that. But if we need to use radioButton itself to place the button any where in a view.

we need to have include one more parameter in htmloption array()

'uncheckValue'=>null

Usage ¶

echo CHtml::radioButton('btn',false,array('value'=>'1','name'=>'btnname','uncheckValue'=>null)); 
CHtml::radioButton('btn',false,array('value'=>'2','name'=>'btnname','uncheckValue'=>null)); 

//or we can use it in activeRadioButton()


echo $form->radioButton($model,'name',array('value'=>1,'uncheckValue'=>null));
echo $form->radioButton($model,'name',array('value'=>2,'uncheckValue'=>null));

so we can place any where in a page
