how would a make a page viewable if your logged in. i didnt have any luck looking for another topic maybe someone could point me in the right direction. thank you.

Search the forum for user authentication, login, authentication etc or have a look on the Wiki. There are already-made libraries that allow you to do this with varying levels of complexity or you could do it yourself using sessions.

thx i just found them i guess i should have kept looking. can someone please delete this topic.

Well there are lots of solutions to this. And there are plenty of libraries and such that people have written. If you do a search you'll likely find a few of them. This is what I usually do:

I have a login controller that checks the login data in a model. If it matches I set a variable called logged_in in my session:

Code:

$this->session->set_userdata('logged_in', TRUE);

Then I have a little helper that I wrote which contains the following:

Code:

// Checks if logged in and redirects to $redirect if false
function checkLogin($redirect = '') {
    $CI =& get_instance();
    $logged_in = $CI->session->userdata('logged_in');
    
    if ($redirect != '')
    {
        if ($logged_in == FALSE)
            redirect($redirect);
    }
    
    else
    {
        if ($logged_in == FALSE)
            redirect('login/');
    }
}

// Returns true if logged in - false otherwise
function isLoggedIn() {
    $CI =& get_instance();
    
    $logged_in = $CI->session->userdata('logged_in');
    return $logged_in ? TRUE : FALSE;
}

So now, in the constructor for my login controller (called login) I put:

Code:

$this->load->helper('login');
        if (isLoggedIn())
            redirect('user/');

And on any controller/function I want to protect I put:

Code:

$this->load->helper('login');
        checkLogin();

And there you go.

EDIT: Seems I was a little too slow

maybe i should explain this better. i want to add a tab to the navigation that can only be seen if your logged in.

[eluser]Pascal Kriete[/eluser]
Ok, well assuming you're using the code I posted you would put this in your controller:

Code:

$this->load->helper('login');

And then in your view you would do:

Code:

<?php if (isLoggedIn()) : ?>
stuff you only want to show when logged in
<?php endif; ?>

Hope that helps,

well im using FAL and i got it to where you have to be logged in to see the page so i have this

Code:

$this->freakauth_light->check('user');

what would i use to hide the tab?

[eluser]Pascal Kriete[/eluser]
I've never used FAL, but according to their documentation, you could use this:

Code:

$this->freakauth_light->isValidUser();

Which will return true if the user is logged in. So basically do this in your controller:

Code:

$data['logged_in'] = $this->freakauth_light->isValidUser();

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

And in your view you put:

Code:

<?php if ($logged_in): ?>
whatever
<?php endif; ?>

well im trying to do this with the tab. i added the code to the controller and i added the rest of the code to the view file and im getting an error. this is what my view file looks like. its for the menu tabs.

Code:

<?php $ci_uri = trim($this->uri->uri_string(), '/'); $att = ' id="active"';?>
    <ul id="navlist">
        <li&lt;?= $ci_uri == ''? $att: ''?&gt;>&lt;?=anchor('', 'home')?&gt;</li>
        <li&lt;?= $ci_uri == $this->config->item('Hotel_uri')? $att: ''?&gt;>&lt;?=anchor($this->config->item('Hotel_uri'), 'hotels')?&gt;</li>
        <li&lt;?= $ci_uri == $this->config->item('Info_uri')? $att: ''?&gt;>&lt;?=anchor($this->config->item('Info_uri'), 'info')?&gt;</li>
        <li&lt;?= $ci_uri == $this->config->item('FAL_login_uri')? $att: ''?&gt;>&lt;?=anchor($this->config->item('FAL_login_uri'), 'login')?&gt;</li>
        &lt;?php if ($logged_in): ?&gt;<li&lt;?= $ci_uri == $this->config->item('profile_uri')? $att: ''?&gt;>&lt;?=anchor($this->config->item('profile_uri'), 'Profile')?&gt;</li>&lt;?php endif; ?&gt;
        <li&lt;?= $ci_uri == $this->config->item('FAL_changePassword_uri')? $att: ''?&gt;>&lt;?=anchor($this->config->item('FAL_changePassword_uri'), 'change password')?&gt;</li>
        <li&lt;?= substr($ci_uri, 0, 5) == 'admin'? $att: ''?&gt;>&lt;?=anchor('admin', 'admin')?&gt;</li>
    </ul>

Hmm, I don't see any mistakes in your code.
Is it a specific error?
Does it work without the if statement?

Otherwise I must say I'm out of ideas .
