    $tglawal=date('Y-m-d', strtotime($this->input->post('tgl1', TRUE)));
    $tglakhir=date('Y-m-d', strtotime($this->input->post('tgl2', TRUE)));
    $data['detail']=$this->traffic_model->cari($tglawal,$tglakhir); 
    $this->load->view('daftar_traffic', $data); //menampilkan data yang sudah dicari
}

型号代码

function cari($tglawal,$tglakhir){      

$this->db->select('DATE_FORMAT(tgl, %d %M %Y) AS tanggal,COUNT(IF(kategori.parent=35 , VALUE, NULL)) AS Software,  COUNT(IF(kategori.parent=33 , VALUE, NULL)) AS Indent,  COUNT(IF(kategori.parent=32 , VALUE, NULL)) AS Ready, COUNT((DATE_FORMAT(tgl, %d - %m - %Y))) AS Total'); //changed the code here from COUNT(clients.id) AS num_rows
$this->db->from('masalah ');
$this->db->where('DATE(masalah.tgl) >=', $tglawal);
$this->db->where('DATE(masalah.tgl) <=', $tglakhir);
