i want to update my array data from table monitordata, but the data wont update i dont know where's the problem. there's no error in this code too :(
this is my controller
public function ubah($id) {
$data_lama = $this->monitor_m->get($id);
$this->data->tglmonitor = $data_lama->tglmonitor;
$this->data->detail = $this->monitor_m->get_record(array('monitor_data.idMonitor'=>$id),true);
$this->template->set_judul('SMIB | Monitoring')
->render('monitor_edit',$this->data);
}
public function ubahku($id) {
$id = $this->input->post('idMonitor_data');
if($this->input->post('idinven')!=NULL){
$idMonitor = $this->input->post('idMonitor');
$kondisi = $this->input->post('kondisi');
$nobrg = $this->input->post('nobrg');
$keterangan = $this->input->post('keterangan');
$kdinven = $this->input->post('kdinven');
$idinven = $_POST['idinven'];
for($i = 0; $i < count($idinven); $i++){
$data_detail = array(
'idMonitor' => $this->input->post('idMonitor'),
'idinven'=> $idinven[$i],
'kdinven'=> $kdinven[$i],
'nobrg'=> $nobrg[$i],
'kondisi'=> $kondisi[$i],
'keterangan' => $keterangan[$i]);
//print_r($data_detail);
$where = array('idMonitor_data' => $id);
$this->monitordata_m->update_by($where,$data_detail);

public function __construct(){
parent::__construct();
parent::set_table('monitor_data','idMonitor_data');
}
This is MY_Model model i put in core folder.
public function update_by($where = array(), $data = array()) {

<input data-theme="e" style="float: right;" data-mini="true" data-inline="false" data-icon="check" data-iconpos="right" value="Simpan" type="submit" />
<div data-role="collapsible-set" data-mini="true">
<?php foreach ($detail as $items): ?>
<div data-role="collapsible">
<?php echo form_hidden('idMonitor_data', $items['idMonitor_data'] ); ?>
<?php echo form_hidden('idMonitor', $items['idMonitor'] ); ?>
<h4><?php echo '[ '.$items['kdinven'].' ] '.$items['namabrg'] ?> </h4>
<?php echo form_hidden('kdinven', $items['kdinven'] ); ?>
<?php echo form_hidden('idinven', $items['idinven'] ); ?>
<div data-role="controlgroup">

This is the DATABASE result and POST_DATA for method ubahku

Answer 1

You have defined a method named update_by, but you are calling $this->monitordata_m->update($id,$data_detail);. Definitely it should not work. please call $this->monitordata_m->update_by($id,$data_detail); from your controller & check what will happen.

Answer 2

Firstly, Please correction $this->monitordata_m->update($id,$data_detail); to $this->monitordata_m->update_by($id,$data_detail); because your function name is update_by in your monitordata_m model.
Secondly, in your monitordata_m model update_by function have 2 param like $where = array() $data = array(), $where is a array but you calling in controller only $id. Your $id is not array. $where is like that $where = array('id' => $id) //id is where field name from db table
So, ubahku($id) method in your controller call $where in update_by function:
$where = array('id' => $id); // 'id' means "where field name"
$this->monitordata_m->update_by($where,$data_detail);

Answer 3

So, thank you so much for everyone who answer my question. so the problem was when i update the data, system only detect "kondisi[]" and "keterangan[]" as an array because i use this "[]" for both of it, so i just have to add "[]" in the end of every name in html form / views. so system will detect every input as an array. i hope you understand what i'm saying, sorry for my bad english. thank you this case is closed :)
