When session starts header file changes after refreshing the page

Question

New to Codeigniter.

This is my header file. After getting logged in, the header file needs to be changed but it changes after I refresh the page. Same is when I logout. Kindly help.

<!DOCTYPE html>
<html>

<head>
  <link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css">
</head>

<body>
  <nav class="navbar navbar-inverse">
    <div class="container-fluid">
      <ul class="nav navbar-nav">
        <li><a href=<?php echo base_url( 'form/home')?>>HOME</a></li>
        <li><a href=<?php echo base_url( 'form/about')?>>ABOUT</a> </li>
        <li><a href=<?php echo base_url( 'form/contact')?>>CONTACT</a></li>
      </ul>
      <?php
                        if(isset($_SESSION["name"])){
      ?>
        <ul class="nav navbar-nav navbar-right">
          <li><a href=<?php echo base_url( 'form/welcome')?>><?php echo $_SESSION["name"];?></a></li>
          <li><a href=<?php echo base_url( 'form/logout')?>>Logout<span class="glyphicon glyphicon-log-out"></span></a></li>
        </ul>
        <?php
                        }else{
        ?>
          <ul class="nav navbar-nav navbar-right">
            <li><a href=<?php echo base_url( 'form/register')?>>REGISTER<span class="glyphicon glyphicon-user"></span></a></li>
            <li><a href=<?php echo base_url( 'form/login')?>>LOGIN<span class="glyphicon glyphicon-log-in"></span> </a></li>
          </ul>
          <?php
                        }
          ?>
    </div>
  </nav>
</body>

do a refresh/redirect with php on login and logout. im guessing the logic which controls the `$_SESSION` vars is done after this header is outputted. — Lawrence Cherone, Jun 13 '17 at 07:25

@webpic thats what I am asking, is there any need to change header file or need to add something in MVC? — , Jun 13 '17 at 07:29
@LawrenceCherone Please tell what exactly I have to write. I tried redirect("welcome", refresh); Welcome is the view file after Login gets validated, but instead it showed codeigniter's welcome page — , Jun 13 '17 at 07:32
In Your Controller ... $this->load->library('session'); and check it .. like this.. print_r($this->session->all_user_data()); — RïshïKêsh Kümar, Jun 13 '17 at 07:34
@Shihas loaded session library. Sessions works well, problem is that after login, header needs to be changed. — , Jun 13 '17 at 07:36
@Alisha you must be setting/resetting the session variables after loading the header file, put your session related code before you load the header view... — Nishant Solanki, Jun 13 '17 at 07:37
@Alisha .. Can I know which code is you used to redirect .. ? — RïshïKêsh Kümar, Jun 13 '17 at 07:40
@Shihas if($query -> num_rows() == 1) { $row = $query->row(); $data = array('name' => $row->name); $name = $this->session->set_userdata($data); return true; //this is how I held the name of user } — , Jun 13 '17 at 07:42

Change the if condition inorder to create session with a name.

if($query -> num_rows() == 1) 
{ 
  $row = $query->row(); 
  $data = array('name' => $row->name); 
  $this->session->set_userdata('loggin_session',$data); // given a name to session(i.e loggin_session). 
  return true;
}

Now in your View change like following:

<?php 
     $session_data = $this->session->userdata('loggin_session');
     if(isset($session_data['name'])){ 
?> 
     <ul class="nav navbar-nav navbar-right">                  
            <li><a href=<?php echo  base_url('form/welcome')?>><?php echo $_SESSION["name"];?></a></li>
            <li><a href=<?php echo  base_url('form/logout')?>>Logout<span class="glyphicon glyphicon-log-out"></span></a></li>
     </ul>
<?php }else{ ?> 
     <ul class="nav navbar-nav navbar-right">
           <li><a href=<?php echo  base_url('form/register')?>>REGISTER<span class="glyphicon glyphicon-user"></span></a></li>
           <li><a href=<?php echo  base_url('form/login')?>>LOGIN<span class="glyphicon glyphicon-log-in"></span> </a></li>
     </ul>
<?php } ?>

No, Its not. Thanks anyways. I did it just by redirecting. – Jun 13 '17 at 08:31 — , Jun 13 '17 at 08:31
