Everythinbg seems fine, except maybe 2 things :
1) try : redirect('welcome/forms');exit();
2) your form is vulnerable to xss attacks
try :
Code:
$data = array(
'date' => $this->input->post('date',TRUE),
'start_time' => $this->input->post('start_time',TRUE),
'finish_time' => $this->input->post('finish_time',TRUE),
'instructor' => $this->input->post('instructor',TRUE),
);
