How to pass a value from a Model to a controller that did not call that Model - El Forum - 11-23-2012

Hello,



After checking at the Model that username and password are correct I want to go to the Administration panel.

First, I dont know if I am "going the right way" because I am using a

Code:
header("Location: http://localhost/realestate/etc/");


I mean, it takes me alright, but I dont know if that is the way to do it, because

the second issue is that at the Admin Panel I need to have that thing of Welcome Username and the logout link, and it is that Username that I am sending from the Model.

I imagined I would do the session_start () at the Administration panel and then I would do $_SESSION('username') = $username;

any idea what the way to send the $username from the Model so that I can pick it up at the Admin panel?


thank you

You could use
Code:
redirect('realestate/etc','refresh')
instead of header redirect

In the model once you have checked the user exists in the database, you could do something like this

Code:
//your model
if ($Q->num_rows() > 0){
//your code to check user exists
$_SESSION['username'] = $row['username'];
redirect('realestate/etc','refresh')
}else{
//your failed login code
}

Then in the admin panel have something like this
[code]
if(isset($_SESSION['username'])){
    echo 'Welcome '.$_SESSION['username'];
}

Hope that helps

Hello


I tried the snippet as you indicated and it was giving me errors, basically the value was not passed on in the session, that is, the isset would fail.

So, I went and tried this:

Code:
$newdata = array(
             'username'  => $username,
            
             'logged_in' => TRUE
           );
          
           $this->session->set_userdata($newdata);
          
          
          
           redirect('atributos_c/atributos_codigo/','refresh');
        
        
           }


I understand your code as it is straightforward, but for some reason, codeigniter didnt like it, so I went to read the session userguide instructions and well, it works. I am positively sure your code is correct but like I said, maybe some scheme of my code doesn't take it as such. But your point did help me because I saw the logic, then I just put a syntax that worked for me.

thank you

Sorry forgot to tell you to add
session_start();
I was using Native sessions and not codeigniter sessions
But anyway least you solved it Smile

yes, exactly in an afterthought I had that was the reason. It is said that codeigniter sessions are not reliable... I ll see how that goes, and if it keeps fine then ok, otherwise, I ll switch to native php sessions.

thanks again
