1. The label element should have a for attribute to indicate which form element it is for.
2. I'm not sure why you have the ob_start and ob_clean methods in the above -- their typically used only when you want to capture the output as a string -- which we don't need to do here.
3. You shouldn't use things like str_replace in a view, we imagine a view being written and maintained by a web designer whose expertise is design not coding.
