how to update multiple value in codeigniter - php

Question

I have input data that I will fill with different values, I do multiple updates
but I have an error which is:
Unknown column 'Array' in 'field list' UPDATE service SET
charges_order = WHERE array id_service = '1'
how to overcome this?
example img
View
<?php $no = 1; foreach ($invoice as $m) { ?>
<tbody id="tbody">
<form class="form-signin" method="post" action="<?php echo base_url();?>backend/report/update/<?php echo $m->id_service; ?>">
<tr class="deleted">
<td><input type="text" class="form-control" name="charges_order[]" value="<?php echo $m->charges_order;?>"></td>
</tr>
</form>
</tbody>
<div class="box-footer">
<button type="submit" class="btn bg-blue btns-flat margin">Simpan</button>
</div>
<?php } ?>
Controller
public function update($id_service)
{
foreach ($this->input->post('charges_order') as $data) {
$data = array(
'charges_order' => $this->input->post('charges_order')
);
// echo '<pre>', print_r($data);
$this->M_report->update($id_service, $data);
redirect('backend/report');
}
}
Model
public function update($id_service, $data)
{
$this->db->where('id_service', $id_service);
$this->db->update('service', $data);
}

Answer 1

Change your controller to this-
public function update($id_service){
$charges_order = json_encode($this->input->post('charges_order'));
$data = array(
'charges_order' => $charges_order
);
$this->M_report->update($id_service, $data);
redirect('backend/report');
}
This should work for you.

Answer 2

You are in a loop. You must use the variable.
$data = array(
'charges_order' => $data
);

Answer 3

You can convert array into a string and then update the table.
//example
[1,2,3,4] -> "1,2,3,4"
Here is the code
public function update($id_service)
{
$data = array(
'charges_order' => implode(",", $_POST['charges_order'])
);
// echo '<pre>', print_r($data);
$this->M_report->update($id_service, $data);
redirect('backend/report');
}
When you are retrieving, you can reverse the process
public function get_orders($id_service)
{
$this->db->select('charges_order');
$this->db->where('id_service', $id_service);
$result = $this->db->get('service')->result_array();
return explode(",", $result["charges_order"]); //returns an array
}
