<?php echo form_open('stock/updating_stock');?>
<div class="panel-body scroll-menu" style="margin-top:0px;height:170px;padding-top:5px;">
<?php foreach($critical_plus_warning as $data){?>
<input type="hidden" name="id_product[]" value="<?php echo $data->id_product;?>">

</div>
<div class="col-xs-12" style="margin-top:-5px;background-color:white;padding:6px;background-color:white;box-shadow:0px 0px 8px 0px #bababa;"><button type="submit" name="submit" class="btn btn-success">Save data</button></div>
<?php echo form_close();?>
and my controller :
function updating_stock(){
$id = $this->input->post('id_product');
$stok = $this->input->post('update_stock');
$user = $this->data['id'];
for($i=0;$i<count($id);$i++){
$data = array(
array(
'id' => $id,
'stok' => $stok,
'diubah' => $user,
'tgl_diubah'=> date('Y:m:d H:i:s'),
),
);
}
//print_r($data);
$this->stok_adm->update_stok($data);
}
and my models :
function update_stok($data){
$this->db->update_batch($this->table, $data,'id_product');
return $this->db->affected_rows();
}

Answer 1

You need a where clause:
$this->db->where('id', $id);
...I think.

Answer 2

Try this:
Controller
function updating_stock(){
$id = $this->input->post('id_product');
$stok = $this->input->post('update_stock');
$user = $this->data['id'];
for($i=0;$i<count($id);$i++){
$data = array(
array(
'id' => $id,
'stok' => $stok,
'diubah' => $user,
'tgl_diubah'=> date('Y:m:d H:i:s'),
),
);
}
//print_r($data);
$this->stok_adm->update_stok($data,$id);
}
Model:
function update_stok($data,$id){
$this->db->update_batch($this->table, $data,'id_product');
return $this->db->affected_rows();
}

Answer 3

I think in your example update_batch will generate incorrect query beacues you need to update each record in db instead of updating them together - update_batch replaces values in multiple rows which fulfills conditions so there is possibility to update also incorrect rows (check example in documentation). So better idea is to update each single product using it's ID. It could look like that:
Model
function update_stok($data, $id_product){
$this->db->where('id_product', $id_product);
return $this->db->update($this->table, $data);
}
Controller
function updating_stock(){
$ids = $this->input->post('id_product');
$stok = $this->input->post('update_stock');
$user = $this->data['id'];
foreach($ids as $key => $id_product) {
$data = array(
'stok' => $stok[$key],
'diubah' => $user,
'tgl_diubah'=> date('Y:m:d H:i:s'),
);
$this->stok_adm->update_stok($data, $id_product);
}
}

Answer 4

$data = array(
array(
'title' => 'My title' ,
'name' => 'My Name 2' ,
'date' => 'My date 2'
),
array(
'title' => 'Another title' ,
'name' => 'Another Name 2' ,
'date' => 'Another date 2'
)
);
$this->db->update_batch('mytable', $data, 'title');
