I am not able to load models to the extended My_Router class in codeigniter. Below is my code:

function _validate_request($segments)

return $segments;
}
// Is the controller in a sub-folder?
if (is_dir(APPPATH.'controllers/'.$segments[0]))
{
// Set the directory and remove it from the segment array
$this->set_directory($segments[0]);
$segments = array_slice($segments, 1);
if (count($segments) > 0)
{
// Does the requested controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$segments[0].EXT))
{
show_404($this->fetch_directory().$segments[0]);

// Let's check if there are category segments

I have tried loading the models by using get_instance function provided by codeigniter but seems like it doesnot work. All i need is load the models in extended system library.
There is no access to the CodeIgniter super-global until CI_Base has been called which is extended by Controller. The Controller class then loads the Loader library:
// In PHP 5 the Loader class is run as a discreet
// class. In PHP 4 it extends the Controller
if (floor(phpversion()) >= 5)
{
$this->load =& load_class('Loader');
$this->load->_ci_autoloader();
}
The Router is loaded very on (have a look in system/codeigniter/CodeIgniter.php to see exactly when, on line 99) so has barely anything available.
You can use load_class('Whatever'); to load classes in a different order, but this can really screw with things if you are not careful, and you still wont have access to the database drivers.
Basically, you can't do it this way. You would need to try and directly work with the database library or use native MySQL bindings to access your data.
Here is what i did and it worked..Thanks phil for suggestion.

The following code will solve your problem too and will make your coding lot easier and flexible.
require_once( BASEPATH . 'database/DB' . EXT );
$db = & DB();
$query = $db->query("select ...");
$results = $query->result();
When using the base CodeIgniter class in external Libraries you have to invoke it again like this:
// load it
$CI =& get_instance();
$CI->load->model('model_name');
//use it
$CI->model_name->method()
Hope that helps

In my controller I retrieve a list of messages from the message model. I am trying to add a filter, but the filters are cancelling each other out.
// Controller
public function __construct(Message $messages)
{
$this->messages = $messages;
}
public function index($filter = null)
{
$messages = $this->messages
->actioned($filter == 'actioned' ? false : true)
->ignored($filter == 'ignored' ? true : false)
->get();
return view('...
}
// Model
public function scopeActioned($query, $actioned = true)
{
$constraint = ($actioned ? 'whereNotNull' : 'whereNull');
return $query->$constraint('ts_actioned');
}
public function scopeIgnored($query, $ignored = true)
{
return $query->where('is_ignored', ($ignored ? 'Yes' : 'No'));
}
How can I setup Eloquent so that scopeActioned is only called if $filter is set to 'actioned', and the same for ignored?
Simple Approach:
public function index($filter = null)
{
$query = $this->messages->query();
//applying filter
if($filter == 'actioned') {
$query->actioned();
}
if($filter == 'ignored') {
$query->ignored();
}
$messages = $query->get();
return view('...
}
Another Approach is work in Scope Function.
// Model
public function scopeActioned($query, $actioned = true)
{
if($actioned) {
$query->whereNotNull('ts_actioned');
}
return $query;
}
public function scopeIgnored($query, $ignored = true)
{
if($ignored) {
$query->where('is_ignored', 'Yes');
}
return $query;
}
It create the session but does not go to index2 and index3 always redirect with else and go to index method but i want to go index2 and index3 to handle other panels also.
Session is created successfully for all just comming else condition all the time.
My form data and array is also showing when i using the print_r for my code to view if the data is comming or not.
Problem is it is showing no any error just redirect with file of index method.
My Controller
class Main extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('Main_Model');
$this->load->helper('url');
$this->load->library('session');
$method = $this->router->fetch_method();
$methods = array('index','index2','index3');
if(in_array($method,$methods))
{
if(!$this->session->has_userdata('signup_email'))
{
redirect(base_url('Main/login'));
}
}
}
public function index()
{
if($this->session->has_userdata('signup_email'))
{
$this->load->view('BKO/index');
}
}
public function index2()

if($this->session->has_userdata('signup_email'))
{
$this->load->view('Admin/index');
}
}
public function index3()
{
if($this->session->has_userdata('signup_email'))
{
$this->load->view('Owner/index');
}
}
public function login()
{
//$data['select'] = $this->Main_Model->get_select();
$this->load->view('login');
}
public function login_process()
{
//$roll = $this->input->post('select');
echo $email = $this->input->post('email');
echo $pass = $this->input->post('upass');
$query = $this->Main_Model->login_process($email,$pass);
if($query == TRUE)
{
$this->session->set_userdata('signup_email');
$session = array(
'signup_email' => $email
);
$this->session->set_userdata($session);
redirect(base_url('Main/check_login'));
}
else
{
$this->session->set_flashdata('error','Invalid Email or Password');
redirect(base_url('Main/login'));
}
}
public function check_login()
{
if($this->session->userdata() == 'admin#gmail.com')
{
echo "Welcome - <h2>".$this->session->userdata('username')."</h2>";
redirect(base_url('Main/index2'));
}
elseif($this->session->userdata() == 'owner#gmail.com')
{
echo "Welcome - <h2>".$this->session->userdata('username')."</h2>";
redirect(base_url('Main/index3'));
}
else
{
echo "Welcome - <h2>".$this->session->userdata('username')."</h2>";
redirect(base_url('Main/index'));
}
}
public function logout()
{
$this->session->sess_destroy();
redirect(base_url());
}
My Model
public function login_process($email,$pass)
{
//$this->db->select('*');
//$this->db->where('roll_id',$roll);
$this->db->where('signup_email',$email);
$this->db->where('signup_password',$pass);
$query = $this->db->get('signup');
if($query->num_rows() > 0)
{
$this->session->set_flashdata('signup_email');
return true;
}
else
{
return false;
}
}
You missed the parameter here
if($this->session->userdata() == 'admin#gmail.com')
instead it should be
if($this->session->userdata('signup_email') == 'admin#gmail.com')
I am trying to print a controller method's result on view but it is giving me an error:
Undefined variable: $states. Can someone help me to point out what is wrong in my code?
Model code:
public function state_names() {
$query = $this->db->select('name')
->get('place')
->where('parent','India');
$query->db->get();
return $query->result();
}
Controller Code:
public function state_names() {
$st['states'] = $this->place_model->state_names();
if ($this->form_validation->run('resource_signup') == TRUE) {
if (isset($st['states']) && $st['states']->num_rows() > 0) {
$this->load->view('/web/resource_signup',$st);
}
}
return array();
}
View code:
<?php foreach ($states as $state) {
echo $state->name;
}
try this one
public function state_names() {
$this->db->select('name')
$this->db->get('place')
$this->db->where('parent','India');
$query=$this->db->get();
return $query->result_array();
}
In your model you are running query twice - for each method get(). You should run it once:
public function state_names() {
$query = $this->db->select('name')
->where('parent','India')
->get('place');
return $query->result();
}
In your controller you can't check num_rows() because there are results - not full response from database.
public function state_names() {
$st['states'] = $this->place_model->state_names();
if ($this->form_validation->run('resource_signup') == TRUE) {
if (isset($st['states'])) {
$this->load->view('/web/resource_signup',$st);
}
}
return array();
}
Your Problem is 2 place First in Model and second in controller
if (isset($st['states']) && $st['states']->num_rows() > 0)
and Model
Model Solution
public function state_names() {
$query = $this->db->select('name')
->where('parent','India')
->get('place');
// $query->db->get();
if($query->num_rows() > 0){
return $query->result();
}
}
N.B [ Here Where will be first and get will be last its good practice ];
Controller Solution :
public function state_names() {
$st['states'] = $this->place_model->state_names();
if ($this->form_validation->run('resource_signup') == TRUE) {
if (isset($st['states']) ) {
$this->load->view('/web/resource_signup',$st);
}
}
return array();

I currently have a relationship between checklistItem and actions as followed:
public function action()
{
return $this->belongsTo(Action::class, 'action_id', 'id');
}
public function checklistItem()
{
return $this->hasOne(ChecklistItem::class, 'action_id', 'id');
}
I currently made a method, when saving an action, the checklistItem status should also change depending on what was chosen:
public static function saveFromRequest(Request $request)
{
if (($action = parent::saveFromRequest($request)) !== null){
if (!is_null($action->checklistItem)) {
$action->checklistItem->value->status = $action->switchStatusChecklist($action);
//Need to update or save this specific checklistItem
$action->checklistItem->save();
}
}
return $action;
}
function switchStatusChecklist($action)
{
switch($action->status) {
case 'closed':
$status = 'checked';
break;
case 'canceled':
$status = 'notapplicable';
break;
default:
$status = 'open';
break;
}
return $status;
}
Problem:
My checklistitem does not get updated.
I have just created a library class in laravel.
class Message {
public static $data = array();
public function __construct() {
// If session has flash data then set it to the data property
if (Session::has('_messages')) {
self::$data = Session::flash('_messages');
}
}
public static function set($type, $message, $flash = false) {
$data = array();
// Set the message properties to array
$data['type'] = $type;
$data['message'] = $message;
// If the message is a flash message
if ($flash == true) {
Session::flash('_messages', $data);
} else {
self::$data = $data;
}
}
public static function get() {
// If the data property is set
if (count(self::$data)) {
$data = self::$data;
// Get the correct view for the message type
if ($data['type'] == 'success') {
$view = 'success';
} elseif ($data['type'] == 'info') {
$view = 'info';
} elseif ($data['type'] == 'warning') {
$view = 'warning';
} elseif ($data['type'] == 'danger') {
$view = 'danger';
} else {
// Default view
$view = 'info';
}
// Return the view
$content['body'] = $data['message'];
return View::make("alerts.{$view}", $content);
}
}
}
I can use this class in my views calling Message::get(). In the controllers, I can set the message as Message::set('info', 'success message here.'); and it works perfectly fine.
However, I can not use this class for flash messages redirects using Message::set('info', 'success message here.', true). Any idea, whats wrong in this code?
First problem is the constructor function is not called when using the above get and set methods, with minor modification the code is now working. :)
class Message {
public static $data = array();
public static function set($type, $message, $flash = false) {
$data = array();
// Set the message properties to array
$data['type'] = $type;
$data['message'] = $message;
// If the message is a flash message
if ($flash == true) {
Session::flash('_messages', $data);
} else {
self::$data = $data;
}
}
public static function get() {
// Check the session if message is available in session
if (Session::has('_messages')) {
self::$data = Session::get('_messages');
}
// If the data property is set
if (count(self::$data)) {
$data = self::$data;
// Get the correct view for the message type
if ($data['type'] == 'success') {
$view = 'success';
} elseif ($data['type'] == 'info') {
$view = 'info';
} elseif ($data['type'] == 'warning') {
$view = 'warning';
} elseif ($data['type'] == 'danger') {
$view = 'danger';
} else {
// Default view
$view = 'info';
}
// Return the view
$content['body'] = $data['message'];
return View::make("alerts.{$view}", $content);
}
}
}
