Hi all,
Im a newbie to codeIgniter. I have a login form. And if I successfully login I have to display a welcome message using session variable and also display some basic information from the database on the homepage. How can I achieve it.
Please help.

Regards

the first function to set flashdata (to do a session variable, like an alert)
the second function to pull some info from the database (from a table called users) and load a new view that should show that data in the variable $database_users (just do a foreach loop and iterate over each item echoing it out)

example welcome controller

Code:
&lt;?php

class welcome extends controller{

    function welcome(){parent::controller();}

    function index(){

        $this->load->view('welcome');

    }

    function flash_me(){

        $this->session->set_flashdata(array('alert'=>'here is an alert! display it by looking for flashdata in the view'));

        redirect('welcome');

    }

    function database_users(){

        $data['database_users'] = $this->db->select('*')->from('users')->limit(5)->get()->result_array();

        $this->load->view('welcome_database_result',$data);

    }

}

the example view to go with the database query, i put the flash_show() function into a helper for my projects and just call it where i want to show flashdata.

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;Welcome!&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;?php

function flash_show()

{

    $ci = get_instance();

    $alert = $ci->session->flashdata('alert');

    if($alert!=''){

        echo '<code>'.$alert.'</code>';

    }

}

?&gt;

&lt;?php flash_show(); ?&gt;

&lt;?php foreach($database_users as $item){ ?&gt;

    <h1>Showing user #&lt;?=$item['id'];?&gt; in the users table</h1>

    &lt;?=$item['username']?&gt;<br />

    &lt;?=$item['password']?&gt;<br />

&lt;?php } ?&gt;

&lt;/body&gt;

to go with this make a database table called users with an id, username and password field and make a 5 or 6 rows manually just to get a feel for how its accomplished. i do my queries by method chaining one line but usually people don't do that, they will throw it on multiple lines etc this is just my preference.
