Extending RadioField for readonly logic

The CMS Questions
1

Hi,

I’m having a hard time extending the RadioField with some readonly logic.

This code, working for the other fields, is not working:

class MyFieldField extends RadioField {
  public function readonly() {
   // Some code here to determine true or false
    return true;
  }
}

However, this code is working:

class MyFieldField extends RadioField {
  public $readonly = true;
}

Of course I can’t put any advanced logic in the later approach. Also this is not consistent with the way other fields work.
Is this a bug with the RadioField or am I missing something here?

Thank you,
Georg

The readonly stuff in the Radio field is handled in the input method, to overwrite this, you would have to modify this method. You can create a readonly method and then call this within the input method.

So instead of :slight_smile:

  if($this->readonly) {
      $input->attr('disabled', true);      
    }

change it to

  if($this->readonly()) {
      $input->attr('disabled', true);      
    }

Thank you, this was it! :slight_smile:
