laravel 4 display query user by 1d - php

Question

I am using Laravel 4 for a web project , I am creating an admin panel
in the admin I have admin/profile/{id} to display user profile like firstname lastname etc..
in my AdminController I have :
// get the Admin Profile page
public function getProfile($id) {
// get the user from the database
$user = User::find($id);
$this->layout->content = View::make('admin.profile', array('user' => $user));
}
but what happens I keep getting errors if I just go to admin/profile without any user id? , how do i make it work?
Basically how to make if the page doesn't exist to go to the dashboard or something like that ? for example if they tried admin/test and test is not a method there , if they are login it will go ot teh dashboard , if not it will go to login page?

You're asking two questions:
I get a 404 error if I go to admin/profile without a user ID. How can I redirect to the login page?
How can I redirect to a login page if the user is not logged in.
For the first question, you can do it a couple of ways. One solution is to add a route that matches anything after all your other route definitions:
Route::get('{any_url}', function(){ return Redirect::route("login"); });
This must be the last route defined because it will match any URL.
Another way to do it would be to catch the NotFoundHttpException in your start/global.php file. Add this code:
App::error(function(\Symfony\Component\HttpKernel\Exception\NotFoundHttpException $exception, $code)
{
return Redirect::route("login");
});
Both of these examples redirect to a named route called login.
As for your second question, the correct way to handle this is to use the auth filter. In your filters.php file, you can add something like this:
Route::filter('auth', function($route)
{
// is the user authorized? if not, redirect to the login page
if (!user_is_authorized())
{
// redirect to the login page
return Redirect::route('login');
}
});
Where the user_is_authorized function is just shorthand for whatever check you do in your code. For information on using the auth filter, see http://laravel.com/docs/routing#route-filters.

Answer 2

You can simply add a missing handler (handles 404) like this:
App::missing(function($e){
// Log the missing url
Log::error($e);
// You may redirect to home
return Redirect::to('/');
// Or redirect to a 404 route that is declared
// to show a custom 404 page from that route
return Redirect::to('missing');
});
Put the code (given above) in your app/start/global.php file. For the missing url/route you need to crate add a route in your routes.php file like this:
Route::get('missing', function(){
// show the view: errors.missing
$this->layout->content = View::make('errors.missing');
});
Create a view as views/errors/missing.blade.php and in your missing.blade.php view, show a fancy message to inform the visitor that, the requested page/url is not available and add a link to your home page in that 404 page.
