Am trying to load view file in application/core/MY_Controller.php but its giving as follows.
Message: Undefined property: Edustaticlanding::$load
Filename: core/MY_Controller.php
Function is as follows in MY_Controller.php
function menu(){
$arrr = array();
return $arrdata['menu'] = $this->load->view('menu',$arrr,true);
}
And am calling this function in controller(Edustaticlanding.php) as follows.
function __construct(){
$this->menucontent = $this->menu();
print_r($this->menucontent); die;
}
Pls correct me.. where its going wrong.. thanks
On application/core/MY_Controller.php
Add public $data = array() like below
<?php
class MY_Controller extends CI_Controller
{
public $data = array();
public function __construct()
{
parent::__construct();
$this->data['menu'] = $this->menu();
}
public function menu(){
return $this->load->view('menu', NULL, TRUE);
}
}
On the controller then once add public $data = array(); you can access the menu on view
You have to use $this->data now on controller
<?php
class Example extends MY_Controller {
public $data = array();
public function index() {
$this->data['title'] = 'Welcome to Codeigniter';
$this->load->view('example', $this->data);
}
}
On the example view now you can echo
<?php echo $menu;?>
Add extends CI_Controller to your core controller like following codes:
class MY_Controller extends CI_Controller {
Please check below mentioned solution. You need to call parent constructor first. So it will load all basic configurations.
First extent CI_Controller class and call parent constructor like describe below
class MY_Controller extends CI_Controller {
public function __construct{
parent::__construct();
}
}
Please let me if it not works.
contrller:News.php
This is my controller News
<?php class News extends CI_Controller {
public function __construct()
{
}
public function getShowIN_News()
{
return $result;
} } ?>
contrller:Category.php
This is my controller Category
<?php class Category extends CI_Controller {
public function __construct()
{
}
public function category()
{
require('news.php');
$test = new News();
$data["headlines"] = $test->getShowIN_News();
} }?>
By using an empty constructor, you're making it so that CI_Controller::__construct() isn't called, and that's where everything in the framework is initialized.
I know you've put it there to hack it so you can call one controller from another, but it is very intentionally made that way, exactly so you don't do this.
I am creating a master controller so that every other controllers on my app extend the master (MY_Controller).
My problem is how to make loading a model more abstract, let me show you the code to better explain.
class MY_Controller extends CI_Controller
{
protected $model;
function __construct()
{
parent::__construct();
}
function get($order_by)
{
$this->load->model($this->model);
$query = $this->$this->model->get($order_by);
return $query;
}
}
I declare a protected variable $model in the master controller so that on the extending controller i can asign it a value:
class Home extends MY_Controller {
public function __construct() {
parent::__construct();
$this->model = "home_model";
}
public function index()
{
$test = $this->get('id');
}
}
The problem is that on MY_Controller i cant load the model
$this->$this->model->get();
i get the following error: Message: Object of class Home could not be converted to string
any help will be appreciated , thank you !
Why do not save the value you assign to protected global $model variable in a variable inside the function as such:
class MY_Controller extends CI_Controller{
protected $model;
function __construct(){
parent::__construct();
}
function get($order_by){
$_model = $this->model // I added this line.
$this->load->model($_model); // I modified this line.
$query = $this->$_model->get($order_by); // I modified this line.
return $query;
}
}
The $this->$this->model->get() is your problem. If you want to use an object property ($this->model) inside a chain like this, you need to wrap it in braces: $this->{$this->model}->get().
i am trying to make a core class in my codeigniter but its giving error that Unable to locate the specified class: Loader.php.
My Core class is MY_base.php and code is.
class MY_base extends CI_Controller{
public function load_header(){
$this->load->model('mod_practice');
$headData=$this->model->get_header();
$this->load->view('header',$headData);
}
}
My model Mod_practice.php code is
class Mod_practice extends CI_Model{
public function get_header(){
$query = $this->db->get('header');
$result = $query->result_array();
return $result;
}
}
My home.php ( main controller) code is
class Home extends MY_loader{
function index(){
parent::MY_base();
}
}
but when i try to run Home controller its giving me the following error
Unable to locate the specified class: Loader.php.
Where can be the error ? Thanks in advance.
You are doing something wrong. You need to construct CI_controller first.
class MY_base extends CI_Controller{
public function __construct()
{
parent::__construct();
// Your own constructor code
}
public function load_header(){
$this->load->model('mod_practice');
$headData=$this->model->get_header();
$this->load->view('header',$headData);
}
}
And now you can do this:
class Home extends MY_base{
public function __construct()
{
parent::__construct();
// Here you have access to load_header() function
}
}
Ou - and also your create MY_base and then refer to MY_loader.
may bee you can use HMVC Codeigniter https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc
I am using hierarchical MVC model in codeigniter. I create a controller called template and inside it a function called sample_template. Then a view called sample_template_v created and call it inside the template controller. I create another controller called Admin and called Template->sample_template($data); inside its 2 funtions.
MY_Controlle.php
<?php
class MY_Controller extends MX_Controller
{
function __construct()
{
parent::__construct();
$this->load->module('Template');
}
}
Admin.php
<?php
class Admin extends MY_Controller
{
function __construct()
{
parent::__construct();
}
function index()
{
$data['content_view'] = 'admin/admin_v';
$this->Template->sample_template($data);
}
function about()
{
$data['content_view'] = 'admin/about_v';
$this->Template->sample_template($data);
}
}
Template.php
<?php
class Template extends MY_Controller
{
function __construct()
{
parent::__construct();
}
function sample_template($data = NULL)
{
$this->load->view('Template/sample_template_v', $data);
}
}
sample_template_v.php file---->
<h5>This is the main Template.</h5>
<?php $this->load->view($content_view); ?>
Error:
If you want to call a method from the object you need to initiaze the object and then call a method. Make sure $this->template is set in your case it isn't.
$this->template = new Template();
$this->template->sample_template($data);
