如何使用CodeIgniter解决日期范围搜索

Question

Controller code

public function getcari(){

    $tglawal=date('Y-m-d', strtotime($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
}

Model Code

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);
$this->db->join('kategori, kategori.kategori=masalah.kategori', 'left');
$this->db->group_by('tanggal');
$query = $this->db->get();
return $query->result();
}

View Code

Answer 1

In my opinion, your problem is because you didn't load the model correctly. So your controller took the traffic_model to be null .
