CodeIgniter From Scratch: Day 6 – Login

Wonderful. That was a great tutorial, Jeff!
I loved how many things you covered and I didn’t mind the the video being longer than usual.

100 Kudos

Hey Jeff, question about the last 5 mins ( i had it until then X) )

when you are validating the user session, the link is too: (under login.php)

redirect(‘site/members_area’);

However, isn’t going directly to members_area function on site.php skipping the

is_logged_in()

function? Which results in the view being loaded regardless.

When I set

redirect(‘site/is_logged_in’); and add $this->members_area(); to the end of that function it works, but you can still visit the memebrs_area directly

still a little confused haha

for all those who want to check if the username was allready taken or allready exist you can add your own form validation for unique values.

it’s the 3rd hack in that post which will help you check if the username was taken or not.

I have tested this, it works perfectly and saves you a lot of trouble

Thanks a lot Jeffrey!
I’ve just started a new project with CI and this tutorial has helped me so much. I now understand much more the basics in CI and I have deepen some of my knowledge in php.

Keep up the good work!

It’s an amazing tutorial! Just a few questions:
If I wanna use this in a real project, what I have to change about security? I mean, what should I re-code to code and database be safety against hacking and protect data? Because codeigniter 1.7.2 doesn’t have any good auth and I wanna create mine, but I have some doubts about security.
Thank you for your help :)

Hi great tutorial! I’m doing an internship and these videotuts are a great help solving my assignment.

I’m having a slight problem thow…

When I hit the logout-link in the members_area-view I get redirected back to the login_view, as I should. But then: when I hit the backbutton in the browser I’m still able to acces the members_area. I’m wondering if anybody knows how to prevent this?

Thanks once again Jeff. Thoroughly enjoying your tutorials. This one was a little long, but its a huge help :) Definitely gives me a good code base in which to refer to in the future as I get my feet wet with CodeIgniter.

Hi all,

First, Jeff, thanks so much for these tutorials on codeigniter. I’d just like to say that I really appreciate the work you’re doing, and that your tutorials are very easy to follow.

I have a question related to one which has already been asked, but not suitably answered (at least for me!) I’m hoping someone can offer some help!

At the moment, the is_logged_in() function is the following:

function is_logged_in()
{
$is_logged_in = $this->session->userdata(‘is_logged_in’);
if(!isset($is_logged_in) || $is_logged_in != true)
{

echo ‘You don\’t have permission to access this page. Login‘;
die();
//$this->load->view(‘login_form’);
}
}

The tutorial says that we shouldn’t echo things directly from a controller, they should be done with a view. So, I did the following, using the template:

function is_logged_in()
{
$is_logged_in = $this->session->userdata(‘is_logged_in’);
if(!isset($is_logged_in) || $is_logged_in != true)
{
$data['main_content'] = ‘no_permission’;
$this->load->view(‘includes/template’, $data);
}
}

To test, if I login, then logout, clear cookies and try to access my members area, I get the no permission view as I’d expect. However, right beneath that, I get the members area stuff even though I’m not logged in. Can anyone offer some knowledge as to why this happens?

Thanks very much,
SK

Great tutorial, up until i hit a snag!

Instead of being redirected to the ‘site/members_area’ i get redirected to ‘login/validate_credentials’? In fact it goes straight to it regardless of what i put into the login form? A noob i know but i really can’t seem to figure it out.

Can anyone help?

HI Jeff ,
Great tutorial
in bast I love To develop my Own Class bout when i see $this->tut i Love working With FW
bout i have note that
debuging in codeigniter mean that i must read all my Work … is that TRUE?

Jeff,

Am I correct in saying that it really doesn’t matter where some of these logic pieces go, as long as they are referenced properly in the code?

For instance, you chose to put most every controller function in login.php. Then when it came to displaying the “Members Only” info you chose to create site.php and display that members area view in that controller. Theoretically this shouldn’t matter right?

Maybe you’ll get to this later, but if you are writing a multi-page site, wouldn’t you pretty much create sub-folders in each of the controllers, models and view directories corresponding to your pages? So if you had an About Us page and a Contact Us page, would you typically create a sub-folder in each of the master folders called aboutus and contactus:

application–>Controllers–>aboutus–>[controller files]

application–>Models–>aboutus–>[model files]

application–>Views–>aboutus–>[view files]

Is there a “best practice” here?
