                <!-- END / NAVIGATION -->               
        </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.

You're not defining the variable $headerContent before you're trying to use it in your Adminhome_Controller. — M. Eriksson

From where you are getting value in $headerContent? I think you may be calling instance variable as a local variable is your issue. Call like $this->headerContent — Vinay

I want assign that <header></header> tag to headerContent variable present in headerview.php. — Kevin

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);
