What do form validation errors return as when empty?

I want to show my form validation errors indivudually and i was wondering... do empty validation errors return as blank strings, or as FALSE?

Code:

echo form_error('field_name');

is all you need to ouput the errors providing the validation rules are set up correctly.

Empty strings.

I'd suggest poking through the source code yourself to see how it works. Helps you learn and answers your question.

You could also probably use the php function gettype figure that out pretty quick.
