        <p class="decent-margin"><a href="<?php echo site_url("login/forgotpw") ?>"><?php echo lang("ctn_181") ?></a></p>

this is a part of my register page "controller"

if (empty($fail)) {
    // Check for any default user groups
    $default_groups = $this->user_model->get_default_groups();
    foreach($default_groups->result() as $r) {
        $this->user_model->add_user_to_group($userid, $r->ID);
    }
    $this->session->set_flashdata("globalmsg", $success);
    redirect(site_url("login"));
}

Note: make sure you have loaded session library

In login view to show msg use this line of code :

<?php echo $this->session->flashdata('globalmsg');?>

Code should be like this (use wherever you want to show):

<div id="container">
<div class="row">
    <?php echo $this->session->flashdata('globalmsg');?>
    ..........

</div>
</div>

Set your flash data in register page "controller" like this :

$this->session->set_flashdata("globalmsg", 'Thank you , you have been registered');
redirect(site_url("login"));
