Saving data from a drop down list in CodeIgniter - codeigniter

Question

I created a menu page where it has a drop down menu with a list of menus from the database and it also has a textbox to enter new menus.
The problem I'm having is that I can't seem to figure out how to save my dropdown. So for example I have a menu called "About Us" in the drop down list and I want to create a new menu called "Team", and "Team" is a child of "About Us"
So in my table I would have something like this
id | parent | title
------------------------
1 | NULL | About Us
2 | 1 | Team
Menu Controller
function get_data_from_post()
{
$data['title'] = $this->input->post('title', TRUE);
$data['parent'] = $this->input->post('parent', TRUE);
if(!isset($data)){
$data = '';
}
return $data;
}
function get_data_from_db($update_id)
{
$query = $this->get_where($update_id);
foreach($query->result() as $row){
$data['title'] = $row->title;
$data['parent'] = $row->parent;
}
return $data;
}
function create()
{
$update_id = $this->uri->segment(3);
$submit = $this->input->post('submit', TRUE);
if($submit == "Submit"){
//person has submitted the form
$data = $this->get_data_from_post();
}else{
if(is_numeric($update_id)){
$data = $this->get_data_from_db($update_id);
}
}
if(!isset($data)){
$data = $this->get_data_from_post();
}
//$titles = array();
$query = $this->get('title');
foreach($query->result() as $row){
$titles[] = $row->title;
}
$data['titles'] = $titles;
$data['update_id'] = $update_id;
$data['view_file'] = "create";
$this->load->module('templates');
$this->templates->admin_template($data);
}
function submit()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('title', 'Title', 'required|xss_clean');
if($this->form_validation->run($this) == FALSE){
$this->create();
}else{
$data = $this->get_data_from_post();
$update_id = $this->uri->segment(3);
if(is_numeric($update_id)){
$this->_update($update_id, $data);
}else{
$this->_insert($data);
}
redirect('menus/manage');
}
}
create.php view
<div class="row">
<div class="col-md-12">
<h2>Create Menus</h2>
<h5>Welcome Jhon Deo , Need to make dynamic. </h5>
</div>
</div>
<hr />
<?php
echo validation_errors("<p style='color: red;'>", "</p>");
echo form_open('menus/submit/'.$update_id);
?>
<div class="row">
<div class="col-md-12">
<form role="form">
<div class="form-group">
<select name="menus">
<?php
foreach($titles as $title){
echo "<option value=".$title.">".$title."</option>";
}
?>
</select>
</div>
<div class="form-group">
<label>Title</label>
<!-- <input class="form-control" /> -->
<?php
$data = array(
'name' => 'title',
'id' => 'title',
'value' => $title,
'class' => 'form-control',
);
echo form_input($data);
?>
</div>
<?php
$data = array(
'name' => 'submit',
'id' => 'submit',
'value' => 'Submit',
'class' => 'btn btn-success',
'style' => 'width: 100%',
);
echo form_submit($data);
?>
</form>
</div>
</div>
<?php
echo form_close();
?>
UPDATE:
this is what I have when I print_r($titles)
Array
(
[0] => About Us
[1] => Home
)
If there is anything you don't understand or if you need me to give more information please let me know.

You should have declared a model. From there, you can create a function that will save the values in the database that you initialize via controller. You should utilize the MVC pattern of it. CodeIgniter has a great documentation to read about what I am pointing out.. https://codeigniter.com/user_guide/overview/mvc.html?highlight=model
