Modify array data in a form within a foreach loop - php

Question

There have a form in a view page that take data as a multidimensional array.In edit mode that form value is fetching and showing data through a foreach loop.
Now my problem is i'm unable to modify that form data in that foreach loop and send it to database. I gone through some posts about foreach key concept but how do I take modified value here in html and send it to database within this foreach loop?
My code fetching data properly but fail to update data.
Here is my code of view page :
<table class="table table-striped" id="dataTable">
<thead>
<tr>
<th>Subscription</th>
<th>Description</th>
<th>Interval</th>
<th>Amount</th>
<th></th>
</tr>
</thead>
<tbody>
<?php
if (!empty($invoice_detail)) {
foreach ($invoice_detail as $key => $result) { ?>
<tr>
<td><input type="text" name="invoice[$key][invoice_detail_subs]" id="invoice_detail_subs"
value="<?php echo $result->invoice_detail_subs; ?>"/></td>
<td><input type="text" name="invoice[$key][invoice_detail_desc]" id="invoice_detail_desc"
value="<?php echo $result->invoice_detail_desc; ?>"/></td>
<td><input type="text" name="invoice[$key][invoice_detail_interval]" id="invoice_detail_interval"
value="<?php echo $result->invoice_detail_interval; ?>"/></td>
<td><input type="text" name="invoice[$key][invoice_detail_amount]" id="invoice_detail_amount"
value="<?php echo $result->invoice_detail_amount; ?>"/></td>
<td></td>
</tr>
<?php }
} ?>
</tbody>
</table>
Here it is Update code in in controller :
if ($this->input->post('Submit')) {
$query = $this->db->query(
"SELECT * FROM ".$this->db->dbprefix."invoice_details WHERE invoice_detail_invoie_id ='".$id."' "
);
$fetch = $query->row();
$rows = $query->num_rows();
if ($id) {
$data1 = [
'invoice_detail_subs' => $this->input->post('invoice_detail_subs'),
'invoice_detail_desc' => $this->input->post('invoice_detail_desc'),
'invoice_detail_interval' => $this->input->post('invoice_detail_interval'),
'invoice_detail_amount' => $this->input->post('invoice_detail_amount'),
'invoice_detail_mddt' => date("Y-m-d H:i:s")
];
$this->db->update('invoice_details', $data1, 'invoice_detail_invoie_id = '.$id);
}
}

update code in controller
if ($this->input->method()=="post") {
if ($id) {
$data1 = ['invoice_detail_subs'=> $this->input->post('invoice_detail_subs'),
'invoice_detail_desc' => $this->input->post('invoice_detail_desc'),

$this->db->update($this->db->dbprefix."invoice_details", $data1,['invoice_detail_invoie_id'=>$id]);
}
}
$query = $this->db->select('*')->where(["invoice_detail_invoie_id"=>$id])->get($this->db->dbprefix."invoice_details");
$fetch = $query->row();
$rows = $query->num_rows();
