$file_directory = "uploads/";
$new_file_name = date("d-m-Y ") . rand(000000, 999999) .".". $file_info["extension"];

if(move_uploaded_file($_FILES["result_file"]["tmp_name"], $file_directory . $new_file_name))
{   
    $file_type	= PHPExcel_IOFactory::identify($file_directory . $new_file_name);

    $objPHPExcel = $objReader->load($file_directory . $new_file_name);
    $sheet_data	= $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
    foreach($sheet_data as $data)
    {
        $result = array(
                'Loat_NO' => $data['A'],
                'C_Name' => $this->input->post('name'),
                'Lab' => $data['V'],
                'C_Shape' => $shape,
                'C_Carat' => $data['C'],
                'C_Weight' => $data['C'],
                'C_Color' => $C_Color,
                'C_Clarity' => $C_Clarity,
                'C_Rap' => $data['F'],
                'C_Discount' => $supplierdiscount,
                'C_Rate' => ($data['H'])?$data['H']:'',
                'C_NetD' => $data['I'],
                'C_DefthP' => $data['S'],
                'C_TableP' => $data['T'],
                'C_Cut' => $C_Cut,
                'C_Polish' => $C_Polish,
                'C_Symmetry' => $C_Symmetry,
                'C_Fluorescence' => $C_Fluorescence,
                'Milky' => ($data['P'])?$data['P']:'',
                'Certi_NO' => $data['W'],
                'Key_Symbols' => $data['X'],
                'C_Length' => $C_Length,
                'C_Width' => $C_Width,
                'C_Depth' => $C_Depth,
                'Location' => '16',
                'is_delete' => '0',
        );
        $this->Uploaddiamond_Model->postDiamond($result);
    }
}

Now Call model $this->Uploaddiamond_Model->postDiamond($result);

function postDiamond($result)
{
    $this->db->insert('diamond_master',$result);
    return true;
}
