codeigniter flashdata not clearing

I'm a newbie to codeigniter and I'm creating a project in which users are created and managed. here I'm using flashdata to display the temporary messages like "user created",etc.,

My code to set flash data is

       $this->session->set_flashdata('message', 'User Created.');

In my view I called it as 

$this->session->flashdata('message');

My problem is that when the user is created,flashdata is displayed and when i click home link the flash data is still available but when i click refresh/home again it disappears. I want it to be cleared when i click the home link for the first time itself. Is there a way to code it??.

If nothing else helps, just extend the Session library and add a clear_flashdata function.

<?php defined('BASEPATH') or exit('No direct script access allowed');

// application/libraries/Session/MY_Session.php
class MY_Session extends CI_Session
{

    public function __construct(array $params = array())
    {
        parent::__construct($params);
    }


    /**
     * Clear flashdata
     *
     * Legacy CI_Session compatibility method
     *
     * @param   mixed   $data   Session data key or an associative array
     * @return  void
     */
    public function clear_flashdata($data)
    {
        $this->set_userdata($data, null);
    }
}

if you want to clear set_flash in controller or another view file, then you can use this simple code.

$this->session->set_flashdata('error', 'User not found...'); //create set_flash

unset set_flash

//echo "<pre>"; print_r($_SESSION); die; //for check 

if(isset($_SESSION['error'])){
    unset($_SESSION['error']);
}

You can use a Ajax framework for automatically hide the flash message.Also their contains all of the flash operation.

You can get more information from here. https://github.com/EllisLab/CodeIgniter/wiki/Ajax-Framework-For-CodeIgniter

You must redirect the page somewhere after $this->session->set_flash('item','value');

Example:

if ($this->form_validation->run() == FALSE){
    $this->session->set_flashdata('error',validation_errors());
    redirect(base_url().'user/login');
}
else{
    $this->session->set_flashdata('success','Thank you');
    redirect(base_url().'user/login');
}

Usually developer make a mistake when they submit data to same page. They set flash data but forget to redirect.

The flashdata is supposed to display once.

And it gets disappears on page refresh.

So, if you redirect the page to another, it should work.

If you do not refresh the page, you can do it through jQuery.

Say your div displaying flash:

<div id="flash-messages">Success Message</div>

Write jQuery:

<script type="text/javascript">
$(function(){
  $("#flash-messages").click(function(){$(this).hide()});
});
</script>

Flashdata will only be available for the next server request, and are then automatically cleared.

if($user_created)
{
    $this->session->set_flashdata('success', 'User created!');
    redirect('login');
}
else
{
    redirect('register');
}

You should redirect after user created. Then when next time you click on home link it will not appear, try this,

$this->session->set_flashdata('message', 'User Created.'); 
redirect(base_url().'home.php');// you can change accordingly
