If I understand correctly, I think this is what you are looking for.
public function index($state = null, $category = null)
{
$this->load->model('M_kegiatan');
$data['username'] = $this->session->userdata('username');
if (!empty($state) || !empty ($category))
{
$data['kegiatan'] = $this->M_kegiatan->get_filtered($state, $category);
}
else
{
$data['kegiatan'] = $this->M_kegiatan->get_kegiatan();
}
$this->load->view('beranda', $data);
}
Add this function to the model
public function get_filtered ($status, $category)
{
$this->db->order_by('tanggal','desc');
If (!empty($status))
{
$this->db->where('status',$status);
}
If (!empty($category))
{
$this->db->where('kategori',$category);
}
$query = $this->db->get('kegiatan');
return ($query->num_rows() > 0) ? $query->result() : NULL;
