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

In order for set_checkbox to work properly, an actual validation rule needs to be used on that element. I ran into this problem and could not get the value to show on a resubmit until I included:

$this->form_validation->set_rules('checkbox_name', 'checkbox_title', 'trim');

Then, everything worked perfect.
