convert to CI

Thanks for help.  After revising the codes, if I click the navigation link:

http://127.0.0.1/backend_CI/index.php/cp...ntents.php

Instead of
http://127.0.0.1/backend_CI/index.php/cpages/contents

I wonder why?




navigation.php

PHP Code:

<li class="active"><a href="index.php"><i class="icon icon-home"></i> <span>Administrator</span></a></li>
            <li class="submenu">
                <a href="#"><i class="icon icon-th-list"></i> <span>Categories</span> <span class="label">2</span></a>
                <ul>
                    <li><a href="pcategories.php">Parent categories</a></li>
                    <li><a href="scategories.php">Sub Categories</a></li>
                </ul>
            </li>
            <li><a href="<?php echo site_url('cpages/pages'); ?>"><i class="icon icon-tint"></i> <span>Pages</span></a></li>
            <li><a href="<?php echo site_url('cpages/slideshows'); ?>"><i class="icon icon-pencil"></i> <span>Slideshow</span></a></li>
            <li><a href="<?php echo site_url('cpages/contents'); ?>"><i class="icon icon-th"></i> <span>Content</span></a></li>
            <li><a href="<?php echo site_url('cpages/galleries'); ?>"><i class="icon icon-th-list"></i> <span>Galleries</span></a></li>
            <li><a href="<?php echo site_url('cpages/newsletters'); ?>"><i class="icon icon-th-list"></i><span>Newsletters</span></a></li> 


controllers/cpages.php

PHP Code:

public function pages() {  $this->load->view('pages');  }
    
    public function slideshows() {  $this->load->view('slideshows');  }

    public function contents() {  $this->load->view('contents');  }
    
    public function galleries() {  $this->load->view('galleries');  }

    public function newsletters() {  $this->load->view('newsletters');  }
