Can anyone shine a light on how to determine which radio button has been selected when the form has been submitted?
I am using CActiveForm::radioButtonList
?
You don't need to determine it. Client will transmit its value in POST
data.
For example such code
<?=$form->radioButtonList($person,'gender_code',array('m'=>'Male','f'=>'Female')); ?>
will form POST[gender_code]=m
or POST[gender_code]=f
