这里我有一个数组,在这个数组中我又有一个数组名
studentAbsentId
,现在我想在数据库中插入
studentAbsentId
,就像这里的
studentAbsentId
2一样,
studentAbsentId
2不存在,所以我需要插入两行

我的更新代码打印($params)

现在我只想拿学生证,怎么办

预期结果

试试这个,它会有帮助:)


试试这个

$test = array('studentAbsentId' => array('2','3'),'studentAbsentDate' => '2017-04-18','reg_date' => '2017-04-18 04:41:21','created_by' => '1');

    foreach($test['studentAbsentId'] AS $tet)
    {
        $array_val = array('studentAbsentId' => $tet,'studentAbsentDate' => $test['studentAbsentDate'],'created_by' => $test['created_by']);

        // echo "<pre>";print_r($array_val);

        $this->db->insert('table_name',$array_val);
    }
$test=array('studentAbsentId'=>array('2','3'),'studentAbsentDate'=>'2017-04-18','reg_date'=>'2017-04-18 04:41:21','created__by'=>'1');
foreach($test['studentAbsentId']作为$tet)
{
$array\u val=array('studentAbsentId'=>$tet,'studentAbsentDate'=>$test['studentAbsentDate'],'created_'=>$test['created_by']);
//echo”“;print_r($array_val);
$this->db->insert('table\u name',$array\u val);
}
