string conversion error in array codeigniter - php

Question

On my controller I have a error on this line 'edit' => site_url('admin/users_group_controller_update') .'/'. $this->getId($controller)
When I refresh my page it throws the error Array to string conversion
A PHP Error was encountered Severity: Notice Message: Array to string
conversion Filename: user/users_group_update.php Line Number: 47
Not sure what to do on that because I need to add variable $controller in to $this->getId($controller);
What changes is best suited to make this work.
<?php
class Users_group_update extends Admin_Controller {
public function __construct() {
parent::__construct();
$this->load->model('admin/user/model_user_group');
}
public function index() {
$data['title'] = "Users Group Update";
$controller_files = $this->getInstalled($this->uri->segment(3));
$data['controller_files'] = array();
$files = glob(FCPATH . 'application/modules/admin/controllers/*/*.php');
if ($files) {
foreach ($files as $file) {
$controller = basename(strtolower($file), '.php');
$do_not_list = array(
'customer_total',
'dashboard',
'footer',
'header',
'login',
'logout',
'menu',
'online',
'permission',
'register',
'user_total'
);
if (!in_array($controller, $do_not_list)) {
$data['controller_files'][] = array(
'name' => $controller,
'installed' => in_array($controller, $controller_files),
'edit' => site_url('admin/users_group_controller_update') .'/'. $this->getId($controller)
);
}
}
}
$this->load->view('template/user/users_group_form_update', $data);
}
public function getInstalled($name) {
$controller_data = array();
$this->db->select();
$this->db->from($this->db->dbprefix . 'user_group');
$this->db->where('name', $name);
$query = $this->db->get();
foreach ($query->result_array() as $result) {
$controller_data[] = $result['controller'];
}
return $controller_data;
}
public function getId($controller) {

Change this line
'edit' => site_url('admin/users_group_controller_update') .'/'. $this->getId($controller)
to
'edit' => site_url('admin/users_group_controller_update' .'/'. $this->getId($controller))

Answer 2

With in my files variable I had to use the db function to get it to work. No errors show now all fixed.
<?php
class Users_group_update extends Admin_Controller {
public function __construct() {
parent::__construct();
$this->load->model('admin/user/model_user_group');
}
public function index() {
$data['title'] = "Users Group Update";
$controller_files = $this->getInstalled($this->uri->segment(3));
$data['controller_files'] = array();
$files = glob(FCPATH . 'application/modules/admin/controllers/*/*.php');
if ($files) {
foreach ($files as $file) {
$controller = basename(strtolower($file), '.php');
$do_not_list = array(
'customer_total',
'dashboard',
'footer',
'header',
'login',
'logout',
'menu',
'online',
'permission',
'register',
'user_total'
);
if (!in_array($controller, $do_not_list)) {
$this->db->where('name', $this->uri->segment(3));
$this->db->where('controller', $controller);
$query = $this->db->get($this->db->dbprefix . 'user_group');
if ($query->num_rows()) {
$row = $query->row();
$data['controller_files'][] = array(
'name' => $controller,
'installed' => in_array($controller, $controller_files),
'edit' => site_url('admin/users_group_controller_update' .'/'. $row->user_group_id)
);
}
}
}
}
$this->load->view('template/user/users_group_form_update', $data);
}
public function getInstalled($name) {
$controller_data = array();
$this->db->select();
$this->db->from($this->db->dbprefix . 'user_group');
$this->db->where('name', $name);
$query = $this->db->get();
foreach ($query->result_array() as $result) {
$controller_data[] = $result['controller'];
}
return $controller_data;
}
}
