Question

$time = strtotime('08/09/2017');

$a = date('Y-m-d',$time);

$this->db->select('gt.shiftkerja','gt.tanggal','i.jenis','i.konsinyasi','gp.group');
$this->db->from('tbl_ikhd gt');
$this->db->join('tbl_ikdt dt','gt.notransaksi=dt.notransaksi','left'); 
$this->db->join('tbl_item i' ,'dt.kodeitem=i.kodeitem','left'); 
$this->db->join('group_posting gp','gp.kode_group=i.jenis and gp.konsinyasi=i.konsinyasi','left');
$this->db->where('gt.tanggal', $a); 
$this->db->group_by('gt.shiftkerja','gt.tanggal','i.jenis','i.konsinyasi','gp.group');
$this->db->order_by ('gt.shiftkerja','gp.group');
return $this->db->get();

Answer 1

您忘记加入result()

 return $this->db->get()->result();

Answer 2

使用以下方法在var_dump($this->db->error());中调试数据库级别错误：

$this->db->select('gt.shiftkerja, gt.tanggal, i.jenis, i.konsinyasi, gp.group');

显然，您有两个错误：

在select语句中必须是：

return $this->db->get()->result_array();//returns result in array format
您必须在对象或数组中返回结果，如下所示：

return $this->db->get()->result();//returns result in object format
