---MY CONTROLLER WITH FORM VALIDATION---
public function update_nik_pindah_kelurahan($id_surat_pindah){
$this->load->library('form_validation');
$i = 0; // untuk loopingnya
$a = $this->input->post('nik_pindah');
if ($a[0] !== null){
foreach ($a as $row => $val){
$this->form_validation->set_rules("nik_pindah[$i]","nik_pindah", "integer|callback_nik_pindah_available");
}
}
$this->form_validation->set_message('required', 'Mohon isi %s terlebih dahulu');
$this->form_validation->set_message('integer', 'Isi %s hanya menggunakan angka');
if ($this->form_validation->run() == FALSE){
$this->edit_nik_pindah_kelurahan($id_surat_pindah);
} else {
$id_surat_pindah = $this->input->post('id_surat_pindah');
$id_surat = $this->input->post('id_surat');
$i = 0; // untuk loopingnya
$a = $this->input->post('nik_pindah');
if ($a[0] !== null) {
$data = array(
'id_surat' => $id_surat,
'id_surat_pindah' => $id_surat_pindah
);
foreach ($a as $row) {
$dataaa = [
'id_surat' => $id_surat_pindah,
'nik_pindah' =>$row,
];
$wheree = array(
'id_surat' => $id_surat_pindah
);
$this->db->where('id_surat', $id_surat_pindah);
$update = $this->db->update('nik_pindah', $dataaa);
if ($update) {
$i++;
}
}
$where = array(
'id_surat_pindah' => $id_surat_pindah
);
$this->m_pindah_kelurahan->update_data($where, $data, 'surat_pindah');
}
redirect('admin_pindah_kelurahan/index');
}
}
---MY CONTROLLER WITHOUT FORM VALIDATION---
public function update_nik_pindah_kelurahan($id_surat_pindah){
if ($this->form_validation->run() == FALSE){
$id_surat_pindah = $this->input->post('id_surat_pindah');
$id_surat = $this->input->post('id_surat');
$i = 0; // untuk loopingnya
$a = $this->input->post('nik_pindah');

];
$wheree = array(

$this->db->where('id_surat', $id_surat_pindah);
$update = $this->db->update('nik_pindah', $dataaa);
if ($update) {
$i++;
}
}
$where = array(
'id_surat_pindah' => $id_surat_pindah
);
$this->m_pindah_kelurahan->update_data($where, $data, 'surat_pindah');
}
redirect('admin_pindah_kelurahan/index');
}
}
---MY VIEWS---
<?php
foreach ($nik_pindah_kelurahan as $np) :
if (empty($np->nik_pindah)) { ?>
<input type="text" name="nik_pindah" class="form-control" value="belum tersedia"><br>
<?php } else {?>
<input type="text" name="nik_pindah[]" class="form-control" value="<?php echo $np->nik_pindah ?>"><br>
<?php } endforeach; ?>
If with or without form validation will updating data but all column where id_surat is same (not particular value)
like this:

Everytime the foreach makes a loop, $this->db->where() has the same condition because $id_surat_pindah has always the same value, so you're updating the same rows once and once again. Also (if I understand it correctly), keep in mind that if $id_surat_pindah is not a unique key, everytime you make an UPDATE all the rows with its value will be affected.
Otherwise, I would recommend you to check your code using update_batch() instead the loop: https://www.codeigniter.com/userguide3/database/query_builder.html?highlight=update_batch
