Get radio button's value from a form by PHP I have been developing validations for my form.

It is possible to get text input's value like;

$password = Craft::$app-&gt;request-&gt;getBodyParam('password');

However, this function seems not to work for radio button fields. Could you tell me how to get radio button's value?
I have solved it by myself;

$application = $event-&gt;sender-&gt;application;


Even for radio button's value, no suffix is necessary like value.
