i have a group of radio buttons whose value is checked randomly everytime you refresh the page, now that works fine, everytime you refresh the page the checked values moves randomly but the problem i have is getting the actual of a checked radio button. i have tried this...

 

$goal_checked = $_POST['goal_chk'];

echo $goal_checked;

 

But nothing happens. Any ideas on how to make this possible. Thanks a lot you guys.

You don't get the values of the checked POST until you send it in the form.

 

Why not just use the value of $goal for what you need to do until they select something in the form.

 

echo $goal;
