Repopulating checkboxes in Codeigniter after Unsuccessful Form Validation

Question

I have a problem repopulating a set of checkboxes after an unsuccessful form validation returns the user back to the same form. Dropdown menus and text inputs could be repopulat

Answer 1

I actually found that it only works if you use like this:

form_checkbox('ambience[]', 'value', set_checkbox('ambience[]', 'value'));

You need the square array brackets on the name for it to work properly.
