How to insert in to two tables from an online from? - php

Question

Is it possible to insert in to two tables at once? I need to insert some data in to a table (students) and then based on the primary key insert in to another (enrollments). Is this possible?
The enrollments table however pulls other primary key from another table called schools (id).
public function add()
{
if(isset($_POST['submit'])) {
$this->student_validation();
if($this->form_validation->run() === TRUE) {
$data = $this->_get_posted_student_data();
$insert_id = $this->student->insert('students', $data);
if($insert_id) {
$this->__insert_enrollment($insert_id);
success($this->lang->line('insert_success'));
redirect('web/index/' . $data['front_school_id']);
} else {
error($this->lang->line('insert_failed'));
redirect('web/admission');
}
} else {
$this->data['post'] = $_POST;
}
}
$this->data['schools'] = $this->schools;
$this->data['add'] = TRUE;
$this->layout->title($this->lang->line('add') . ' ' . $this->lang->line('student') . ' | ' . SMS);
$this->layout->view('web/index', $this->data);
}
private function __insert_enrollment($insert_id)
{
$data = array();
$school = $this->student->get_school_by_id($this->input->post('front_school_id'));
$data['student_id'] = $insert_id;
$data['school_id'] = $this->input->post('front_school_id');
//$data['class_id'] = $this->input->post('class_id');
//$data['section_id'] = $this->input->post('section_id');
$data['academic_year_id'] = $school->academic_year_id;
//$data['roll_no'] = $this->input->post('roll_no');
$data['created_at'] = date('Y-m-d H:i:s');
//$data['created_by'] = logged_in_user_id();
$data['status'] = 1;
$this->db->insert('enrollments', $data);
}
private function _get_posted_student_data()
{
$items = array();
$school_id = $this->session->userdata('front_school_id');
$items[] = 'first_name';
$items[] = 'middle_name';

$data['age'] = floor((time() - strtotime($data['dob'])) / 31556926);

You need $this->db->insert_id() to get last inserted id which will get from this.
$this->db->insert('students', $data);
$insert_id = $this->db->insert_id();
if(!empty($insert_id)) {
$this->__insert_enrollment($insert_id);
success($this->lang->line('insert_success'));
redirect('web/index/' . $data['front_school_id']);
} else {
error($this->lang->line('insert_failed'));
redirect('web/admission');
}
