I'm using the initial helpers to create a set of radio buttons, such as:

<?= $this->formRadio('pg1_3', $this->formObj->pg1_3, null, array(1=>' Yes',2=>' No'),'&nbsp;')?>

creates:

<input name="pg1_3" value="" type="hidden"><label style="white-space: nowrap;"><input name="pg1_3" value="1" type="radio"> Yes</label>&nbsp;<label style="white-space: nowrap;"><input name="pg1_3" value="2" type="radio"> No</label>

Upon submitting this form, the controller extracts the "hidden" value, which is "". How can I get the value from the radio button that the user selected in the controller, such as $this->_request->getPost('pg1_3'). It extracts a blank string because that is the value of the hidden field which has SAME name as the radio button. Please help.

Sorry, it appears that I had a typo in my controller code. I am able to extract the param with $this->_request->getPost('pg1_3'). One question, however, why is the hidden form created along with the radio button?

Hi sclaerhout.

At the first thought I think it's because in case a radio button is not selected you would still have the post var "pg1_3". If a radio button is not selected then it will not send a variable in the POST. Same applies with checkboxes. If a checkbox is not selected the variable is not created.
