Laravel: Undefined variable: fname

[Jake.20]

Greetings guys can you point to me what is the problem here?

This is the code that produces the error. That is in my views:

<h7 id="header-label">Welcome, {{ $fname }} |</h7>

This is the controller:

class ProfileController extends BaseController {


    public function showProfile() {
        $items = DB::table('item_tbl')->get();
     //     Auth::check();

     //     if (Auth::check())
        // {
        //     return "true";
        // } else {
        //  return "false";
        // }
        //$fname = Auth::user()->[firstname];
        // var_dump(Session::get('fname'));
        return View::make('profile')->with('items', $items);
    }
}

and this is the model:

if (Auth::attempt(array('username' => $data['username'], 'password' => $data['password'])))
        {   
            $fname = Auth::user()->firstname;
            return Redirect::to('profile');
            //return View::make('profile')->with('name', $fname);
            //return Redirect::to('profile')->with('name', $fname);
            // $fname =;

        } else {
            return Redirect::back()
                ->with('message', 'Invalid username/password');
        }

This is my route:

Route::get('profile', 'ProfileController@showProfile');

I break those codes down. I found out that; when i use the Session::get('fname') it returns null.

[Jake.20]

Sorry i forgot to mention the models name. the model's name is User

Controller - ProfileController
Views - profile.blade.php

[Jake.20]

wrong forum sorry

Hi, you can do:

Redirect::to('profile')->with('fname', Auth::user()->firstname);

Or:

Session::put('fname', Auth::user()->firstname);
Redirect::to('profile');

Then you have to get the value from session:

$data['items'] = DB::table('item_tbl')->get();
$data['fname'] = Session::get('fname');
return View::make('profile')->with('items', $data);

But:

1. when using with() the value is flashed to session, and won't be available in the next request

2. you can get the value directly in the controller:

   $data['fname'] = Auth::user()->firstname;
   

And also it always return false when i use Auth::check()

Can you show the login process (form and receiving route)? To restrict the access to the profile controller use the auth filter:

class ProfileController extends BaseController {

    public function __construct()
    {
        $this->beforeFilter('auth');
    }

To restrict the single method you can apply the same or at route level:

Route::get('profile', array(
    'before' => 'auth',
    'uses'   => 'ProfileController@showProfile'
    ));

cereal posting like a pro! Thank you sir! you saved me from a lot of work time. Thanks!

[Jake.20]

But sir can i ask you a question?

I tweaked my code before i posted this topic. I found out that i can only access the fname on the url with localhost/laravel/public/authenticate

public function authenticate() {

        $username = Input::get('username');
        $password = Input::get('password');

        $login = User::tryAuthenticate(Input::all());

        return $login;
        //return Redirect::to('profile')->with('name', $fname);

        }
    }

And when i go to /profile the value assigned to fname is gone. what happen to the value i assigned on fname?

and why can i just use Auth::user()->firstname on the view page? like this ?

{{ Auth::user()->firstname }}

The Auth class is bounded to the User model, so when the authentication is satisfied you can access his information, check:

• http://laravel.com/docs/security#authenticating-users

in particular read the Accessing The Logged In User paragraph.

In your case you can do:

public function authenticate()
{
    $fname = User::tryAuthenticate(Input::all());
    return Redirect::to('profile')->with('name', $fname);
}

And make the model method return the name, but it is not necessary, as you can always use Auth::user(), so:

public function authenticate()
{
    # true
    if(User::tryAuthenticate(Input::all())) return Redirect::to('profile');

    # false
    return Redirect::to('login')->with('error', 'Error: wrong credentials.');
}

And make User::tryAuthenticate() just return true or false.

[Jake.20]

Another question sir. I tried this and it says false. it should be true right?

    public function showProfile() {
        $items = DB::table('item_tbl')->get();

        if (Auth::check()) {
            return "true";
        } else {
            return "false";
        }

        // $name = Session::get('fname');
        // return View::make('profile')->with('name', $name)->with('items', $items);


     //     if (Auth::check())
        // {
        //     return "true";
        // } else {
        //  return "false";
        // }
        //$fname = Auth::user()->[firstname];
        // var_dump(Session::get('fname'));

    }

Got my problem fixed. The problem is i was using admin_id on my database when my supervisor changed it to id it fixed my problem. So he told me that laravel is strict with convention.

[cereal]

In such cases you can also set the primary key in the (User) model:

<?php

use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface {

    protected $table = 'users';
    protected $primaryKey = 'admin_id';

API:

• http://laravel.com/api/class-Illuminate.Database.Eloquent.Model.html#$primaryKey
• https://github.com/laravel/framework/blob/4.2/src/Illuminate/Database/Eloquent/Model.php#L42

Bye!

[Jake.20]

Ooooooh! didn't know that. Thanks! So it means i can override the default primary key set by the laravel. Thanks sir.
