How to Edit data? Simple question

Then you will need to check if the username is empty or not.

PHP Code:

$data = array(
    if (! empty($this->input->post('username')))
    {
        'person_name'=> $this->input->post('username'),
    }
    'person_d' => $this->input->post('d'),
    'person_department' => $this->input->post('department'),
    'city_id' => $this->input->post('address')
); 


Other wise you are passing the person_name to the database as empty.

A better way of doing this would be to fill in all of the form fields on an edit
then allow them to change the fields.
