CodeIgniter: My upsert function not working with my_model / my_controller - codeigniter

Question

Working with the my_model & my_controller for the first time this month within CodeIgniter, I think I almost have this working.
I got an insert function working properly, now I'm trying to add an update to it if there is an ID.
Here's my code:
function upsert_client($client_id = 0)
{
load_model('client_model');
$this->insertMethodJS();
$this->fields['client'] = $this->_prototype_client();
$user_id = get_user_id();
$company_id = get_company_id();
if ($client_id)
{
$this->data['client'] = $this->client_model->get_record($client_id);
}
if (!$this->ion_auth->in_group(GROUP_NAME_MANAGER, $user_id))
{
redirect('members/dashboard');
}
if ($_POST)
{
$this->load->helper('string');
if ($this->_validate_client())
{
$fields = $this->input->post(null , TRUE);
$fields['user_id'] = $user_id;
$fields['company_id'] = $company_id;
$fields['active'] = 1;
if ($client_id)
{
$fields['id'] = $this->client_model->get_record($client_id);
unset($fields['billing']);
$this->client_model->update($client_id, $fields);
}
else
{
unset($fields['billing']);
$this->client_model->insert($fields);
redirect('members/clients/manage_clients');
}
}
}
$this->template->write_view('content',$this->base_path.'/'.build_view_path(__METHOD__), $this->data);
$this->template->render();
}
function _prototype_client()
{
$fields = array();
$fields['id'] = 0;
$fields['name'] = '';
return $fields;
}
And from my client_model:
class Client_model extends MY_Model {
function get_record($client_id)
{
$query = $this->db->select('id')
->where(array('id'=>$client_id))
->get('clients');
return $query->row_array();
}
}
Everytime I try to edit a "client", it just inserts a new one... All I'm currently trying to edit is the "name" field.
My edit button:
<td><button class="btn btn-inverse" style="float: right;" type="button">Edit</button></td>
Any help is appreciated, thanks! And let me know if you need any additional details...

Answer 1

I never worked with ion auth in particular but from what I see you have a couple of functions that are not referenced correctly.
load_model('client_model');
//Should be
$this->load->model('client_model');
also a few other functions should be referenced as
$this->function_name();
//Instead of just
function_name();
//Unless they are in another library
$this->lib_name->function_name();
I'm not sure if this well solve your problems but just a few things I noticed.

Your hyperlink points to 'add_client' whereas the function you are showing is called 'upsert' Are you calling the correct URL?
