CodeIgniter method Cannot get File Path Correctly

I parsed a html into Header, Sidebar, Content, Footer etc.. And main view put together.. It is working when I calling view from mycontroller/index but it isnt working when I calling view from mycontroller/method.. Pseude Code below;

Controller;

class welcome extends CI_Controller{
   public function index(){
      $data['content'] = "**main**_page";
      $this->load->view('welcome_message',$data);
   }

   public function deneme(){
      $data['content'] = "**another**_page";
      $this->load->view('welcome_message',$data);
   }
}

View;

<html>
  <head>
    <?php $this -> load -> view("includes/head_view");?>
  </head>
  <body>
    <?php $this -> load -> view("includes/navbar_view");?>
    <?php $this -> load -> view($content);?>
    <?php $this -> load -> view("includes/footer_view"); ?>
  </body>
 </html>

Example Sub View

<img src="<?php base_url(); ?>assets/img/image1.jpg">

When I open below address, everything working fine, images loading

http://localhost/myproject

But When open below, images is not loading

http://localhost/myproject/welcome/deneme

I check the images url from Google Chrome> Page Source Code.. The link writing like that; localhost/myproject/welcome/assets/img/image1.jpg

instead of

localhost/myproject/assets/img/image1.jpg

It's adding controller name to all links how can resolve it Thank you

Solution

Where you define your base_url it says "URL to your CodeIgniter root. Typically this will be your base URL, WITH a trailing slash":

$config['base_url'] = 'http://localhost/myproject/';
