How to insert and update multiple selected values with codeigniter? - mysql

Question

So I have a problem with many to many relationships.
Currently, I have surat and surat_user table.
How do I insert data into surat and at the same time insert multiple values from select2 multiple forms into surat_user table and how to get data so I can update it.
UPDATE :
I solve the insert problem please see answer below
But now i have no idea how to update those values.
For example
surat_user
id_surat | id_user
1 | 1
1 | 2
How to update surat_user (in controller and model) if i want to remove one of id_user where 'id_surat = 1`
At the moment i don't know how to fetch the multiple values into select2 form edit so here is mu uncomplete codes :
Controller
public function edit_sm($id_surat){
$this->load->view('template/header');
$this->load->view('template/sidebar');
$where = array('id_surat' => $id_surat);
//$data=array('id_status'=> $this->M_sm->get_option());
$data['surat'] = $this->M_sm->edit_sm($where,'surat')->result();
$this->load->view('v_edit_surat',$data);
$this->load->view('template/footer');
}
public function edit_sm_proses() {
$data = array(
'id_surat'=>$this->input->post('id_surat'),
'no_surat'=>$this->input->post('no_surat'),
'id_status'=>$this->input->post('id_status'),
'id_user'=>$this->input->post('id_user')
);
$where = array(
'id_surat' => $id_surat
);
$this->M_sm->edit_sm_proses($where,$data,'surat');
redirect('SuratMasuk');
}
Model:
public function edit_sm($where,$table){
$this->db->join('status_surat', 'status_surat.id_status = surat.id_status');
return $this->db->get_where($table,$where);
}
public function edit_sm_proses($where,$data,$table){
$this->db->where($where);
$this->db->update($table,$data);
}

Answer 1

Manage to solve the problem by my self.
i change my controller to this:
public function add_sm_proses(){
$data = array(
'no_surat'=>$this->input->post('no_surat'),
'id_status'=>$this->input->post('id_status')
);
$insert = $this->M_sm->trans_surat_user($data);
if($insert=1){
redirect('SuratMasuk');
} else {
echo "<h2>Gagal menambahkan data</h2>";
}
}
change my model to this :
public function trans_surat_user($data){
$this->db->trans_start();
$this->db->insert('surat', $data);
$id_surat = $this->db->query('SELECT surat.id_surat FROM surat ORDER BY id_surat DESC limit 1');
foreach ($id_surat->result() as $row) {
$id_surat_result = $row->id_surat;
}
$id_user = $_POST['id_user'];
foreach ($id_user as $data2) {
array_push($id_user, $data2);
$this->db->query('INSERT INTO surat_user (id_surat,id_user) VALUES ('.$id_surat_result.','.$data2.')');
}
$this->db->trans_complete();
}

Answer 2

class SuratMasuk extends CI_Controller {
public function add_sm_proses(){
$data = array(
'no_surat'=>$this->input->post('no_surat'),
'id_status'=>$this->input->post('id_status'),
);
Select MAX ID from table like this
$id_surat = $this->db->query('SELECT MAX(surat.id_surat) AS maxid FROM surat')->row()->maxid;
Update:-
$id_surat will give MAX ID present in the table. Don't use for next record.
First, Increment it by value 1 and then use it
$id_surat = $id_surat + 1;
$id_user = $this->input->post('id_user') ? $this->input->post('id_user') : array();
First, check if $id_user have values or not otherwise foreach loop will give e error
if(count($id_user) > 0){
foreach ($id_user as $u){
$data_values = array('id_surat' => $id_surat, 'id_user' => $u);
$this->db->insert('surat_user', $data_values);
}
}
$insert = $this->M_sm->add_sm($data);
$insert will not always return 1. So, only check if value exists
if($insert){
redirect('SuratMasuk');
} else {
echo "<h2>Gagal menambahkan data</h2>";
}
}
}

Answer 3

First, Show all record from DB and for each record add a button to edit the record.
Note:- Don't use <form> inside the loop
<a class="btn btn-warning btn-sm" href="<?= base_url('SuratMasuk/edit_sm/'.$row->id_surat)?>"><i class="fa fa-pencil-square-o" aria-hidden="true"></i>Edit</a>
Controller for Edit
I'm just adding backend code here
where and table is reserved word for DB. It is better to not use it or use in another way.
public function edit_sm($id_surat){
$condition_array = array('id_surat' => $id_surat);
$data['surat'] = $this->M_sm->edit_sm($condition_array ,'surat');
}
Model for Edit
Get the record for edit
This function is getting only one record from DB so use row()
public function edit_sm($condition_array ,$record_in){
$this->db->join('status_surat', 'status_surat.id_status = surat.id_status');
return $this->db->get_where($record_in, $condition_array )->row();
}
Now, Form for will show with data populated in it.
Getting updated data from Controller
public function edit_sm_proses() {
$data = array(
'id_surat'=> $this->input->post('id_surat'),
'no_surat'=>$this->input->post('no_surat'),
'id_status'=>$this->input->post('id_status'),
'id_user'=>$this->input->post('id_user')
);
$condition_array = array(
'id_surat' => $this->input->post('id_surat')
);
$this->M_sm->edit_sm_proses($condition_array, $data, 'surat');
redirect('SuratMasuk');
}
Updating data in Model
public function edit_sm_proses($condition_array, $data, $record_in){
$this->db->where($condition_array);
return $this->db->update($record_in, $data);
}
