You can call controller function from view in the following way:

Controller:

public function read() {
    $object['controller'] = $this; 
    $this->load->view('read', $object);
}

View:

// to call controller function from view, do
$controller->myOtherFunct();

Go to the top of your View code and do it like this :

  <?php
     $this->load->model('MyModelName');
     $MyFunctionReturnValue = $this->MyModelName->MyFunctionName($param));
?>

<div class="row">
    Your HTML CODE
</div>

We can also pass controller function as variable in the view page.

class My_controller extends CI_Controller {
    public function index() {
           $data['val']=3;
           $data['square']=function($val){
                               return $val*$val;
                                   };
    $this->load->view('my-view',$data);
}
}

In the view page

<p>Square of <?=$val?>
   <?php 
     echo $square($val); 
   ?>
</p>

The output is 9

One idea i can give is,

Call that function in controller itself and return value to view file. Like,

class Business extends CI_Controller {
    public function index() {
            $data['css'] = 'profile';

            $data['cur_url'] = $this->getCurrURL(); // the function called and store val
            $this->load->view("home_view",$data);
     }
     function getCurrURL() {
                $currURL='http://'.$_SERVER['HTTP_HOST'].'/'.ltrim($_SERVER['REQUEST_URI'],'/').'';
            return $currURL;
     }

}

in view(home_view.php) use that variable. Like,

echo $cur_url;

it is quite simple just have the function correctly written in the controller class and use a tag to specify the controller class and method name, or any other neccessary parameter..

<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Iris extends CI_Controller {
    function __construct(){
        parent::__construct();
        $this->load->model('script');
        $this->load->model('alert');

    }public function pledge_ph(){
        $this->script->phpledge();
    }
}
?>

This is the controller class Iris.php and the model class with the function pointed to from the controller class.

<?php 
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Script extends CI_Model {
    public function __construct() {
        parent::__construct();
        // Your own constructor code
    }public function ghpledge(){
        $gh_id = uniqid(rand(1,11));
        $date=date("y-m-d");
        $gh_member = $_SESSION['member_id'];
        $amount= 10000;
        $data = array(
            'gh_id'=> $gh_id,
            'gh_member'=> $gh_member,
            'amount'=> $amount,
            'date'=> $date
        );
        $this->db->insert('iris_gh',$data);
    } 
}
?>

On the view instead of a button just use the anchor link with the controller name and method name.

<html>
    <head></head>
    <body>
        <a href="<?php echo base_url(); ?>index.php/iris/pledge_ph" class="btn btn-success">PLEDGE PH</a>
    </body>
</html>
