Redirection in laravel without return statement
It's not a best practice to use this method, but to solve your question, you can use this gist.
Create a helper function like:
if(!function_exists('abortTo')) {
function abortTo($to = '/') {
throw new \Illuminate\Http\Exceptions\HttpResponseException(redirect($to));
}
}
then use it in your code:
public function reqLogin(){
if(!Auth::check()){
abortTo(route('login'));
}
}
public function create() {
$this->reqLogin();
return View::make('blogs.create');
}
You should put the check into a filter, then only let the user get to the controller if they are logged in in the first place.
Filter
Route::filter('auth', function($route, $request, $response)
{
if(!Auth::check()) {
Session::flash('message', 'You need to login');
return Redirect::to("login");
}
});
Route
Route::get('blogs/create', array('before' => 'auth', 'uses' => 'BlogsController@create'));
Controller
public function create() {
return View::make('blogs.create');
}
Beside organizing your code to fit better Laravel's architecture, there's a little trick you can use when returning a response is not possible and a redirect is absolutely needed.
The trick is to call \App::abort()
and pass the approriate code and headers. This will work in most of the circumstances (excluding, notably, blade views and __toString()
methods.
Here's a simple function that will work everywhere, no matter what, while still keeping your shutdown logic intact.
/**
* Redirect the user no matter what. No need to use a return
* statement. Also avoids the trap put in place by the Blade Compiler.
*
* @param string $url
* @param int $code http code for the redirect (should be 302 or 301)
*/
function redirect_now($url, $code = 302)
{
try {
\App::abort($code, '', ['Location' => $url]);
} catch (\Exception $exception) {
// the blade compiler catches exceptions and rethrows them
// as ErrorExceptions :(
//
// also the __toString() magic method cannot throw exceptions
// in that case also we need to manually call the exception
// handler
$previousErrorHandler = set_exception_handler(function () {
});
restore_error_handler();
call_user_func($previousErrorHandler, $exception);
die;
}
}
Usage in PHP:
redirect_now('/');
Usage in Blade:
{{ redirect_now('/') }}
