redirect loop error laravel auth - php

Question

hi im trying to make a good user auth form but i ve have had some problems , so first i tried this :
Route::get('login', function()
{
/* Get the login form data using the 'Input' class */
$userdata = array(
'username' => Input::get('username'),
'password' => Input::get('password')
);
/* Try to authenticate the credentials */
if(Auth::attempt($userdata))
{
// we are now logged in, go to admin
return Redirect::to('home');
}
else
{
return Redirect::to('login');
}
});
and this is the form blade page :
{{ Form::open(array('url' => 'login', 'class' => 'form-horizontal')) }}
<div class="control-group">
<label class="control-label" for="username"></label>
<div class="controls">
<input id="username" name="username" type="text" placeholder="" class="input-xlarge" required="">
</div>
</div>
<!-- Password input-->
<div class="control-group">
<label class="control-label" for="password"></label>
<div class="controls">
<input id="password" name="password" type="password" placeholder="" class="input-xlarge" required="">
</div>
</div>
<!-- Button -->
<div class="control-group">
<label class="control-label" for="submit"></label>
<div class="controls">
<button id="submit" name="submit" class="btn btn-inverse"></button>
</div>
</div>
</fieldset>
and it gave me the redirect loop error
and then i tried this :
Route::get('login', function()
{
/* Get the login form data using the 'Input' class */
$user = new User;
$log = array(
$user -> username = Input::get('username'),
$user -> password = Input::get('password')
);
/* Try to authenticate the credentials */
if(Auth::attempt($log))
{
// we are now logged in, go to admin
return Redirect::to('home');
}
else
{
return Redirect::to('login');
}
});
and it gives me :
SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'where clause' (SQL: select * from `users` where `0` is null and `1` is null limit 1)
does anyone knows whats the problem?
first code should have worked perfectly but why redirect error?

Answer 1

Firstfully, change your route names, to:
Route::get('login', function(){}); And Route::get('sign-in', function(){});
Get auth page:
Route::get('login', function()
{
return View::make('your-auth-view');
}
And your sign-in handler should looks like:
Route::get('sign-in', function(){
$userdata = array(
'username' => Input::get('username'),
'password' => Input::get('password')
);
if(Auth::attempt($userdata))
{
// we are now logged in, go to admin
return Redirect::to('home');
}
else
{
return Redirect::to('login');
}
});
And form will change to:
{{ Form::open(array('url' => 'sign-in', 'class' => 'form-horizontal')) }}
P.S. You have a redirect loop, because, you have a two the same routes, and when you submit the form you redirect to login page again and again

Answer 2

If you are using Laravel 4.2 and still have issues after adding
{{ Form::token() }} or
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
Then you can try changing the filter.php file in app directory by adding
Request::getMethod() !== 'GET' on your filter.
Route::filter('csrf', function()
{
if (Request::getMethod() !== 'GET' && Session::token() != Input::get('_token'))
{
throw new Illuminate\Session\TokenMismatchException;
}
});
This has been useful to me too.
