Let me explain about the CodeIgniter session flash message. it's a temporarily stored value. this coding used to set success message and failure message through your controller. Let start to learn how to create CodeIgniter session flash message.

The session store data will available temporarily it will work with single server request. Once get the

next server request session data will clear automatically.

Flash session set code work with your controller functions. Session response code displays your flash view files. Generally, we will success message after submitting the form try to use session message.

Read flash data

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

message - set_flashdata('message') name.

Welcome Controller
Create sample controller class name called to welcome and set your session

<?php 

class Welcome extends CI_Controller {
    
    public function add_user()
    {
        //insert or update code

        $this->session->set_flashdata('message', 'Successfully Added.');
        $this->load->view('index');
    }
    

}

View(index.php)
I have to load the session message index file

<html>

<body>

<?php if($this->session->flashdata('message')){?>
  <div class="alert alert-success">      
    <?php echo $this->session->flashdata('message')?>
