Pass variable from middleware to view via controller in Laravel 5.2 - laravel

Hi I am trying to do the following in Laravel 5.2.
Summary: Pass some variables from middleware to view, via controller
Detailed: When a client is logged in, no matter what route they want, we need to check if they have completed all "setup steps" (each step refers to a different route, e.g. one could be company info, another could be product settings, etc). If they have completed all setup steps, then let them proceed to their chosen route, otherwise we redirect to the appropriate "setup steps" route, whichever one they haven't completed yet.
All client controllers run the same middleware, called NonSuperAdmin. I would like to put the checking of "setup steps" in this middleware, and redirect from there as appropriate. If client is redirected to a setup route by this middleware, we need the "incompleteSetupTasks" collection to be passed on to the relevant view, via the appropriate setup steps controller method.
Is this possible? Any help is much appreciated.

In the middleware use session handler
if($condition === true){
$data = [ //your content ];
Session::flash('your_key', $data);
}
next($request);
This data will also be available in your controller and in view
This is how you can access data in controller
public function yourControllerAction($request)
{
$somevariable = Session::get('your_key');
$viewdata = [
'content' => $somevariable
]
return view('yourview', $viewdata);
}
Or directly access the session data in view
//inblade
<p>
Your html content
#foreach(Session::get('your_key' as $data)
//your stuff
#endif
</p>

May be use Laravel Session to store and read values?

You can pass your setup steps to get or post parameters and check in routes with middleware if these parameters are empty:
Route::get('post/{setup1?}/{setup2?}', ['middleware' => 'role:admin', function ($setup1, $setup2) {
if(empty($setup1) and empty($setup2)){
// do smth
} else {
// redirect
}
}]);
Question marks mean, that they are optional parameters. Hope it was helpful.

view does not seems to see $error variable in laravel middlegroup "auth"

I'm having problem on my view not seeing any $Message variable, which is working on my login controller.
public function index()
{
$data = somedataFromModel::find(1);
return View::make('SomeView',compact(['sampleData' => $data]);
}
public function postOrStoreData(CustomFormRequest $request)
{
/* where update or insert or store occurs */
//after all my updating codes or inserting codes
return back()->with('Message','test');
}
with these codes I am not able to run my view correctly, it does not see $Message
it has the same implementation as my login controller and views.
right now my view needs to be authenticated to be used, so it is under the Middleware Group of 'auth', I also see the MiddleWareGroups, web and api. help me I'm lost.
My only objective is after I post any data, without using AJAX, just standard Form Action and Submit Method, I will display an alertClass with bootstrap.
redirect()->with() stores it in the session.
Per the docs, you thus access it via session('Message') in the view, not $Message.
The syntax may appear similar to view()->with(), but the functionality is not identical.

Laravel 5 and Socialite - New Redirect After Login

Another newb question here, but hopefully someone can shed some light:
I am using Socialite with Laravel 5, and I want to be able to redirect the user to a page on the site after they have logged in. The problem is that using
return redirect('any-path-I-put-here');
simply redirects back to 'social-site/login?code=afkjadfkjdslkfjdlkfj...' (where 'social-site' is whatever site is being used i.e. facebook, twitter, google, etc.)
So, what appears to me to be happening is that the redirect() function in the Socialite/Contracts/Provider interface is overriding any redirect that I attempt after the fact.
Just for clarification, my routes are set up properly. I have tried every version of 'redirect' you can imagine ('to', 'back', 'intended', Redirect::, etc.), and the method is being called from my Auth Controller (though I have tried it elsewhere as well).
The question is, how do I override that redirect() once I am done storing and logging in the user with socialite? Any help is appreciated! Thank you in advance.
The code that contains the redirect in question is:
public function socialRedirect( $route, $status, $greeting, $user )
{
$this->auth->login( $user, true );
if( $status == 'new_user' ) {
// This is a new member. Make sure they see the welcome modal on redirect
\Session::flash( 'new_registration', true );
return redirect()->to( $route );// This is just the most recent attempt. It originated with return redirect($route);, and has been attempted every other way you can imagine as well (as mentioned above). Hardcoding (i.e., 'home') returns the exact same result. The socialite redirect always overrides anything that is put here.
}
else {
return redirect()->to( $route )->with( [ 'greeting' => $greeting ] );
}
}
... The SocialAuth class that runs before this, however, is about 500 lines long, as it has to determine if the user exists, register new users if necessary, show forms for different scenarios, etc. Meanwhile, here is the function that sends the information through from the Social Auth class:
private function socialLogin( $socialUser, $goto, $provider, $status, $controller )
{
if( is_null( $goto ) ) {
$goto = 'backlot/' . $socialUser->profile->custom_url;
}
if( $status == 'new_user' ) {
return $controller->socialRedirect($goto, $status, null, $socialUser);
}
else {
// This is an existing member. Show them the welcome back status message.
$message = 'You have successfully logged in with your ' .
ucfirst( $provider ) . ' credentials.';
$greeting =
flash()->success( 'Welcome back, ' . $socialUser->username . '. ' . $message );
return $controller->socialRedirect($goto, $status, $greeting, $socialUser);
}
}
I managed to workaround this problem, but I am unsure if this is the best way to fix it. Similar to what is stated in question, I got authenticated callback from the social media, but I was unable to redirect current response to another url.
Based on the callback request params, I was able to create and authenticate the user within my Laravel app. It worked good so far but the problems occured after this step when I tried to do a return redirect()->route('dashboard');. I tried all the flavours of redirect() helper and Redirect facade but nothing helped.
The blank page just stared at my face for over 2 days, before I checked this question. The behaviour was very similar. I got redirect from social-media to my app but could not further redirect in the same response cycle.
At this moment (when the callback was recieved by the app and user was authenticated), if I refreshed the page manually (F5), I got redirected to the intended page. My interpretation is similar to what's stated in this question earlier. The redirect from social-media callback was dominating the redirects I was triggering in my controller (May be redirect within Laravel app got suppressed because the redirect from social-media was still not complete). It's just my interpretation. Experts can throw more light if they think otherwise or have a better explaination.
To fix this I issued a raw http redirect using header("Location /dashboard"); and applied auth middleware to this route. This way I could mock the refresh functionality ,redirect to dashboard (or intended url) and check for authentication in my DashboardController.
Once again, this is not a perfect solution and I am investigating the actual root of the problem, but this might help you to move ahead if you are facing similar problem.
I believe you are overthinking this. Using Socialite is pretty straight forward:
Set up config/services.php. For facebook I have this:
'facebook' => [
'client_id' => 'your_fb_id',
'client_secret' => 'your_fb_secret',
'redirect' => '>ABSOLUTE< url to redirect after login', //like: 'http://stuff'
],
Then set up two routes, one for login and one for callback (after login).
In the login controller method:
return \Socialize::with('facebook')->redirect();
Then in the callback function
$fb_user = \Socialize::with('facebook')->user();
// check if user exists, create it and whatnot
//dd($fb_user);
return redirect()->route('some.route');
It should be pretty much similar for all other providers.
We are using the Socialite login in our UserController as a trait. We simply overrode the AuthenticatesSocialiteLogin::loginSuccess() in our controller.
use Broco\SocialiteLogin\Auth\AuthenticatesSocialiteLogin;
class UserController extends BaseController
{
use AuthenticatesSocialiteLogin;
public function loginSuccess($user)
{
return redirect()->intended(url('/#login-success'));
}
....

Pass data from routes.php to a controller in Laravel

I am attempting to create a route in Laravel for a dynamic URL to load a particular controller action. I am able to get it to route to a controller using the following code:
Route::get('/something.html', array('uses' => 'MyController#getView'));
What I am having trouble figuring out is how I can pass a variable from this route to the controller. In this case I would like to pass along an id value to the controller action.
Is this possible in Laravel? Is there another way to do this?
You are not giving us enough information, so you need to ask yourself two basic questions: where this information coming from? Can you have access to this information inside your controller without passing it via the routes.php file?
If you are about to produce this information somehow in your ´routes.php´ file:
$information = WhateverService::getInformation();
You cannot pass it here to your controller, because your controller is not really being fired in this file, this is just a list of available routes, wich may or may not be hit at some point. When a route is hit, Laravel will fire the route via another internal service.
But you probably will be able to use the very same line of code in your controller:
class MyController extends BaseController {
function getView()
{
$information = WhateverService::getInformation();
return View::make('myview')->with(compact('information'));
}
}
In MVC, Controllers are meant to receive HTTP requests and produce information via Models (or services or repositores) to pass to your Views, which can produce new web pages.
If this information is something you have in your page and you want to sneak it to your something.html route, use a POST method instead of GET:
Route::post('/something.html', array('uses' => 'MyController#getView'));
And inside your controller receive that information via:
class MyController extends BaseController {
function getView()
{
$information = Input::get('information');
return View::make('myview')->with(compact('information'));
}
}

Laravel 4 - Setting up routes

I'm working on a site I have inherited and having a little trouble routing to a controller.
When I visit the URL www.domain.com/banners/statistics, it won't return anything.
I also noted that when I try and link to this page via Banner Statistics this also gives me an error on my home page.
Routes.php
Route::resource('banners', 'BannerController');
Route::get('banners/{banners}/activate', 'BannerController#activate');
Route::get('banners/{banners}/deactivate', 'BannerController#deactivate');
Route::get('banners/{banners}/delete', 'BannerController#delete');
Route::get('banners/{banners}/preview', 'BannerController#preview');
Route::any('banners/{banners}/cropresize', 'BannerController#cropresize');
Route::get('banners/statistics', 'BannerController#statistics');
BannerController.php
public function create()
{
$data['title'] = 'Create Banner';
$data['disciplines'] = Discipline::lists('name', 'id');
return View::make('admin.banners.create', $data);
}
public function statistics()
{
return View::make('admin.banners.statistics');
}
The resource controller provides you multiple routes.
Including :
GET /resource/{resource} redirecting to the show action of your controller.
List of all created routes : http://laravel.com/docs/controllers#resource-controllers
So when you call
banners/statistics
Laravel think you want to call the show action with "statistics" as a parameter.
To avoid this, you can put all your custom routes above your resource controller route.
Route::get('banners/{banners}/activate', 'BannerController#activate');
Route::get('banners/{banners}/deactivate', 'BannerController#deactivate');
Route::get('banners/{banners}/delete', 'BannerController#delete');
Route::get('banners/{banners}/preview', 'BannerController#preview');
Route::any('banners/{banners}/cropresize', 'BannerController#cropresize');
Route::get('banners/statistics', 'BannerController#statistics');
Route::resource('banners', 'BannerController');
This way Laravel will call your custom route before the routes created by your resource controller.
You can also use only and except if you don't need some of the resource controller routes.
Route::resource('banners', 'BannerController',
array('except' => array('show')));

Codeigniter paypal_lib->ammount from form?

I need to get the quantity of items from a form and pass that to CI's paypal_lib auto_form:
This is my controller:
function auto_form()
{
$this->paypal_lib->add_field('business', 'admin_1261513315_biz#pixelcraftwebdesign.com');
$this->paypal_lib->add_field('return', site_url('home/success'));
$this->paypal_lib->add_field('cancel_return', site_url('home/cancel'));
$this->paypal_lib->add_field('notify_url', site_url('home/ipn')); // <-- IPN url
$this->paypal_lib->add_field('custom', '1234567890'); // <-- Verify return
$this->paypal_lib->add_field('item_name', 'Paypal Test Transaction');
$this->paypal_lib->add_field('item_number', '001');
$this->paypal_lib->add_field('quantity', $quant);
$this->paypal_lib->add_field('amount', '1');
$this->paypal_lib->paypal_auto_form();
}
I have a library of my own that validates the input and redirects to auto_form on validation. I just need to pass the var $quant to the controller.
How can I achieve this?!
If you're redirecting directly to the auto_form controller method you can setup an argument there to pass your data in:
auto_form($quant)
Then, depending assuming you have no routes, rewriting, or querystrings 'on' (basically a stock CI setup) to interfere, and you are using the URL helper to redirect, you would do your redirect something like this:
redirect('/index.php/your_controller/auto_form/'. $quantity_from_form);
More on passing URI segments to your functions here.
Or if you're already using CI sessions in your application you can add the quantity value to a session variable for later retrieval inside of the auto_form controller method:
// Set After Your Form Passed Validation
$this->session->set_userdata('quant', $quantity_from_form);
// Retrieve Later in Controller Method After Redirect
$this->paypal_lib->add_field('quantity', $this->session->userdata('item'));
More on CI sessions here.
