我尝试保存数据,但我data2
保存column1
时出错。我已将数据添加为数组
$simpan array(
'column1' = $data1,
'column2' = $data2,
'column3' = $data3
);
但不想保存到我的数据库。
public function simpannilaidetail(){
$id_nilai = $this->input->post('id_nilai');
$id_pelajaran = $this->input->post('id_pelajaran');
$get = $this->modelpenilaian->datanilai($id_nilai, $id_pelajaran);
if (count($get) > 0) {
$rs = "";
}else{
$nilaiawal = '0';
**$rs = $this->crudmodel->simpannilaifix($id_nilai, $id_pelajaran, $nilaiawal);**
}
echo $rs;
}
public function simpannilaifix($idn,$idp,$nilaiawal){
$this->db->query("INSERT INTO nilaidetail values('$idn','$idp','$nilaiawal')");
}
已保存,但结果是:
column1 column2 column3
data1,data2 NULL data3
正确的结果必须是这样的:
column1 column2 column3
data1 data2 data3

希望这会对您有所帮助:
使用像这样的普通查询
您还应提供列名
public function simpannilaifix($idn,$idp,$nilaiawal)
{
/*change column_name with your real table column name*/
$sql = "INSERT INTO nilaidetail (column_name1, column_name2, column_name3)
values('".$idn."','".$idp."','".$nilaiawal."')";
$this->db->query($sql);
echo $this->db->insert_id();
}
或者您可以使用ci insert query builder:
public function simpannilaifix($idn,$idp,$nilaiawal)
{
/*change column_name with your real table column name*/
$data = array('column_name1' => $idn,
'column_name2' =>$idp,
'column_name3' => $nilaiawal
);
$this->db->insert('nilaidetail',$data);
return $this->db->insert_id();
}
