</div>
</header>
This header is come to all pages in application. So I want it to assign some variable called headerContent and it is located in Admin_controller. That render function called from any another controller that extends Admin_controller and then it loads the headeview to that pages.
Admin_controller
class Admin_controller extends CI_Controller{
function __construct()
{
parent::__construct();
$this->load->model("Adminmodel","",true);
$headerview = 'headerview';
$this->render($headerview); # calling render() function in same class
}
protected $headerview = 'headerview';
protected function render($headerContent) {
$view_data = array( 'headerContent' => $headerContent);
$this->load->view($this->headerview);
}
}
Another controller below that extends Admin_controller called this render function.
Adminhome_controller.php
<?php
require APPPATH . '/controllers/admin/Admin_controller.php';
class Adminhome extends Admin_Controller{
public function __construct(){
parent::__construct();
$this->load->model("Adminmodel","",true);
public function index(){
$data['content']=$this->load->view("admin/adminhomeview",'',true);
$data['title']='Dashboard';
$adminId=$this->session->userdata('cp_adminid');
$permissions=$this->Adminmodel->getpermissions($adminId);
$row = $permissions->row();
$data['isAdmin'] = 0;
if($row->view == 1 or $row->add == 1 or $row->edit == 1 or $row->deleteRole == 1 ){
$data['isAdmin'] = 1;
}
$this->render($headerContent);
// $this->load->view("admin/headerview",$data);
}
}
?>
But it showing error like Message: Undefined variable: headerContent in Adminhome_controller.php.

Answer 1

you culd create a template view file containing
template view:
<html>
<?php $data = array('permission' => $permission); ?>
<?php $this->load->view('templateincludes/header',$data); ?>
<?php $this->load->view($main_content); ?>
<?php $this->load->view('templateincludes/footer'); ?>
</html>
controler:
$data = array('permission' => '1', 'main_content' => 'folder_to_your_view/view_file_you_want_to_load');
$this->load->view('template', $data);
header view:
<?= $permission ?>

But it showing error like Message: Undefined variable: headerContent
in Adminhome_controller.php
There is no variable with the name $headerContent inside extended class. Seems like you want access the parent/base class's variable.
To overcome this, you can declare protected field inside Parent Controller (Admin_controller.php), and access it inside child controller :
class Admin_controller extends CI_Controller{
protected $headerContent; // declare protected field
protected $headerview = 'headerview';
function __construct()
{
parent::__construct();
$this->load->model("Adminmodel","",true);
$headerview = 'headerview';
$this->render($headerview); # calling render() function in same class
}
protected function render($headerContent) {
$view_data = array( 'headerContent' => $headerContent);
$this->headerContent = $headerContent; // assign value into $headerContent field
$this->load->view($this->headerview);
}
}
And you can access it directly inside child class (Adminhome_controller.php) by using :
$this->render($this->headerContent);
