使用Codeigniter在数据库中存储包含PHP脚本的HTML标记

i'm trying to store html tag that includes php script. This is for the navigation menu, i'm trying to display only the menu for a particular user role.

I'm storing it this way

public function edit_module(){
    $id = $this->input->post('Module_ID', TRUE);
    $update = $this->db->update('ref_modules', array('Module_Name'=>$this->input->post('Module_Name', TRUE), 
                                                    'Module_Menu'=> htmlspecialchars($this->input->post('Module_Menu')),
                                                    'UpdatedBy'=>$this->session->userdata('user_id')), "Module_ID = '$id'");
    if($update){
        return TRUE;
    }
}

For display

 <!--Menu-->
                <!--================================-->
                <div id="mainnav-menu-wrap">
                    <div class="nano">
                        <div class="nano-content">
                            <ul id="mainnav-menu" class="list-group">

                                <!--Category name-->
                                <li class="list-header">Navigation</li>

                                <?php if($this->data['menu']): ?>
                                    <?php foreach($this->data['menu'] as $row): ?>
                                        <?php echo htmlspecialchars_decode($row->Module_Menu); ?>
                                    <?php endforeach; ?>
                                <?php endif; ?>
                            </ul>
                        </div>
                    </div> <!-- nano -->
                </div><!-- mainnav-menu-wrap -->
                <!--================================-->
                <!--End menu-->

When i view the source, its fine but when i click the link, special characters are showing.

http://localhost/folderName/%3C?php%20echo%20base_url(%27citizens%27);%20?%3E

Here's a sample value that i am inserting

<li class="<?php echo ($title == 'Citizens' ? 'active-link' : '');?>">
                                    <a href="<?php echo base_url('citizens'); ?>">
                                        <i class="fa fa-user"></i>
                                        <span class="menu-title">
                                            <strong>Citizens</strong>
                                        </span>
                                    </a>
                                </li> 

Any idea guys? Thanks in advance!

Inserting Html into database For Different user role is not the right way. You can use if Conditions To show your Menu for different User roles.
