我使用的是codeigniter和mysql，我有两张桌子。 第一个表名“checkinout”： 第二个表名“check_times”：
表名： “checkinout”
----------------------------------------------------------------------------
user_id | date | time
----------------------------------------------------------------------------
3 | 2014-09-30 | 05:40:35,06:40:35,09:40:35,12:40:35
3 | 2014-10-01 | 05:40:35,10:30:35
2 | 2014-11-22 | 07:00:35
我想将第一个表中的数据插入到第二个表中 是这样的： 表名： “check_times”
------------------------------------------------------------------------------
user_id | date | in_1 | out_1 | in_2 | out_2
------------------------------------------------------------------------------
3 | 2014-09-30 | 05:40:35 | 06:40:35 | 09:40:35 | 12:40:35
3 | 2014-10-01 | 05:40:35 | 10:30:35 | |
2 | 2014-11-22 | 07:00:35 | | |
=============================================== ===============================
我尝试使用explode（）函数，但它显示每个空值的错误消息。
我的型号名称是“test_model”
这是我的模特函数
public function get_data()
{
$query = $this->db->get('checkinout')->result();
foreach ($query as $result)
{
if($result->check_time)
{
$result->check_time = explode(",", $result->check_time);
}
}
return $query;
}
我的控制器名称是“test”
这是我的控制器功能
public function show()
{
$query = $this->test_model->get_data();
foreach ($query as $row)
{
$data['results'] = array
(
'userid' => $row->userid ,
'check_date' => $row->check_date ,
'in_1' =>$row->check_time[0] ,
'out_1' =>$row->check_time[1] ,
'in_2' =>$row->check_time[2] ,
'out_2' =>$row->check_time[3]
);
$this->load->view('test_view',$data);
}
}
我的观点名称是“test_view”
echo "<pre>";
print_r($results);
结果是

修改后的我的控制器
public function show()
{
$query=$this->test_model->get_data();
foreach ($query as $row)
{
$data['results'] = array();
$data['results']['userid']= $row->userid ;
$data['results']['check_date'] = $row->check_date ;
if(isset($row->check_time[0]))
{$data['results']['in_1'] = $row->check_time[0] ;}
else{$data['results']['in_1'] = '00:00:00' ;}
if(isset($row->check_time[1]))
{$data['results']['out_1'] = $row->check_time[1] ;}
else{$data['results']['out_1'] = '00:00:00' ;}
if(isset($row->check_time[2]))
{$data['results']['in_2'] = $row->check_time[2] ;}
else{$data['results']['in_2'] = '00:00:00' ;}
if(isset($row->check_time[3]))
{$data['results']['out_2'] = $row->check_time[3] ;}
else{$data['results']['out_2'] = '00:00:00' ;}
$this->load->view('test_view',$data);
}
}
谢谢大家，现在很好
