The error occurs when i print the messages for the logged in user sent by others to him. I did var_dump in my controller as well as in my view. I also did {{$threads->count()}} in my view and it showed 27(thread count). But when i access the view file it throws me the above mentioned error.
Here is my controller code
public function index()
{
$currentUserId = Auth::user()->id;
$threads = Thread::getAllLatest()->get();
return view('chatindex', compact('threads', 'currentUserId'));
}
I also printed the currentUserId in view and it also works fine
Here is my view code (where the error occurs)
#extends('layouts.app')
#section('content')
#if (Session::has('error_message'))
<div class="alert alert-danger" role="alert">
{!! Session::get('error_message') !!}
</div>
#endif
#if($threads->count() > 0)
#foreach($threads as $thread)
<?php $class = $thread->isUnread($currentUserId) ? 'alert-info' : ''; ?>
<div class="media alert {!!$class!!}">
<h4 class="media-heading">{!! link_to('messages/' . $thread->id, $thread->subject) !!}</h4>
<p>{!! $thread->latestMessage->body !!}</p>
<p><small><strong>Creator:</strong> {!! $thread->creator()->name !!}</small></p>
<p><small><strong>Participants:</strong> {!! $thread->participantsString(Auth::id()) !!}</small></p>
</div>
#endforeach
#else
<p>Sorry, no threads.</p>
#endif
#stop
It throws me the error Trying to get property of non-object (View: C:\xampp\htdocs\laravel-projects\user_prof\resources\views\chatindex.blade.php)
maybe in your foreach $thread is an array() so use it like one as
$thread['id'], $thread['subject']

I'm trying to pass anINT from this URL: myapp.build/courses/anINT (implemented in the CoursesController) to $id in the Lesson_unitsController function below. I've tried a lot of solutions, but I can't seem to get it right.
The function in the CoursesController which implements the url is:
public function show($id)
{
$course = Course::find($id);
return view('courses.show')->with('course', $course);
}
Part of the show.blade.php file is:
#if(!Auth::guest())
#if(Auth::user()->id == $course->user_id)
Edit Course
Lesson Units
{!!Form::open(['action'=> ['CoursesController#destroy', $course->id], 'method' => 'POST', 'class' => 'float-right'])!!}
{{Form::hidden('_method', 'DELETE')}}
{{Form::submit('Delete', ['class' => 'btn btn-danger'])}}
{!!Form::close()!!}
#endif
#endif
The Lesson_unitsController functions are:
public function index()
{
$lesson_units = Lesson_unit::orderBy('title','asc')->paginate(10);
return view('lesson_units.index')->with('lesson_units', $lesson_units);
}
public function specificindex($id)
{
$course = Course::find($id);
return view('lesson_units.specificindex')->with('lesson_units', $course->lesson_units);
}
And the specificindex.blade.php file is:
#extends('layouts.app')
#section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">Dashboard</div>
<div class="card-body">
Create lesson unit
<p>
<h3>Your lesson_units</h3>
#if(count($lesson_units) > 0)
<table class="table table-striped">
<tr><th>Title</th><th></th><th></th></tr>
#foreach($lesson_units as $lesson_unit)
<tr><td>{{$lesson_unit->title}}</td>
<td>Edit</td>
<td>
{!!Form::open(['action'=> ['Lesson_unitsController#destroy', $lesson_unit->id], 'method' => 'POST', 'class' => 'float-right'])!!}
{{Form::hidden('_method', 'DELETE')}}
{{Form::submit('Delete', ['class' => 'btn btn-danger'])}}
{!!Form::close()!!}
</td>
</tr>
#endforeach
</table>
#else
<p>You have no lesson unit.</p>
#endif
#if (session('status'))
<div class="alert alert-success" role="alert">
{{ session('status') }}
</div>
#endif
You are logged in!

The routes in web.php are:
Route::resource('courses', 'CoursesController');
Route::resource('lesson_units', 'Lesson_unitsController');
Route::get('/courses/{id}', 'Lesson_unitsController#specificIndex');
I want that when the link for Lesson Units is clicked on the page, the id in the url is passed to the specificindex function in the Lesson_unitsController. Now, I get just a blank page. What am I doing wrong?
Try to understand the concept of RESTful and CRUD.
By using Route::resource('courses', 'CoursesController');, Laravel has helped you to register the following routes:
Route::get('courses', 'CoursesController#index');
Route::get('courses/create', 'CoursesController#create');
Route::post('courses/{course}', 'CoursesController#store');
Route::get('courses/{course}/edit', 'CoursesController#edit');
Route::put('courses/{course}', 'CoursesController#update');
Route::delete('courses/{course}', 'CoursesController#destroy');
Then, when you make GET request to myapp.build/courses/123, Laravel will pass the request to the show function of your CoursesController like:
public function show(Course $course)
{
return view('lesson_units.index')->with('lesson_units', $course->lesson_units);
}
Laravel will automatically resolve the Course from your database using the parameter passed into the route myapp.build/courses/{course}.
Note: The variable name $course has to match with the one specify in route /{course}.
You don't have a route set up to handle the $id coming in. The resource method within the Route class will provide a GET route into your Lesson_unitsController controller without an expectation of any variable. It is the default index route, and by default doesn't pass a variable.
There are a couple of ways to do this, but the easiest is to just create a new route for your specific need:
Route::get('lesson_units/{id}', 'Lesson_unitsController#specificIndex');
And then make your specificIndex function in your controller with an incoming variable:
public function specialIndex($id)
{
$course = Course::find($id);
// return view to whatever you like
}
HTH
I'm trying to check if variable is being passed from controller but isn't working, the controller function looks like here:
public function editClient($id)
{
$client = Client::find($id);
// $client_project = DB::table('client_project')->where('client_id',$id)->first()->project_id;
//$project = DB::table('projects')->where('id',$client_project)->first();
$client_projects = Client::find($id)->projects;
return view('cms.public.views.clients.editclient', ['client' => $client, 'client_projects' => $client_projects]);
}
In the client blade I show the projects of each one with this code:
<h3 class="h3client h3clienteedit">Proyectos de {{$client->name}}</h3>
#foreach ($client_projects as $project)
<div class="col-md-3 col3projectofclient">
<h4 class="h4traductiontitle">{{$project->title}}</h4>
<img src="{{ asset('/storage/projects/'.$project->slug.'/header.jpg') }}" class="imgprojectoneditclient">
</div>
#endforeach
But I only want to show it when have projects if not i don't want to show de .
I'm trying to do it with this code:
#if ( !empty($client_projects['slug']))
//code
#endif
pass the variable directly
#if (!$client_projects)
//code
#endif
or
#if ($client_projects->count())
//code
#endif

I'm trying to get a success message back to my home page on laravel.
return redirect()->back()->withSuccess('IT WORKS!');
For some reason the variable $success doesn't get any value after running this code.
The code I'm using to display the succes message:
#if (!empty($success))
<h1>{{$success}}</h1>
#endif
I have added the home and newsletter page to the web middleware group in routes.php like this:
Route::group(['middleware' => 'web'], function () {
Route::auth();
Route::get('/', function () {
return view('home');
});
Route::post('/newsletter/subscribe','NewsletterController#subscribe');
});
Does anyone have any idea why this doesn't seem to work?
You should remove web middleware from routes.php. Adding web middleware manually causes session and request related problems in Laravel 5.2.27 and higher.
If it didn't help (still, keep routes.php without web middleware), you can try little bit different approach:
return redirect()->back()->with('message', 'IT WORKS!');
Displaying message if it exists:
#if(session()->has('message'))
<div class="alert alert-success">
{{ session()->get('message') }}
</div>
#endif
you can use this :
return redirect()->back()->withSuccess('IT WORKS!');
and use this in your view :
#if(session('success'))
<h1>{{session('success')}}</h1>
#endif
Controller:
return redirect()->route('subscriptions.index')->withSuccess(['Success Message here!']);
Blade
#if (session()->has('success'))
<div class="alert alert-success">
#if(is_array(session('success')))
<ul>
#foreach (session('success') as $message)
<li>{{ $message }}</li>
#endforeach
</ul>
#else
{{ session('success') }}
#endif
</div>
#endif
You can always save this part as separate blade file and include it easily.
fore example:
<div class="row">
<div class="col-md-6">
#include('admin.system.success')
<div class="box box-widget">
You can simply use back() function to redirect no need to use redirect()->back() make sure you are using 5.2 or greater than 5.2 version.
You can replace your code to below code.
return back()->with('message', 'WORKS!');
In the view file replace below code.
#if(session()->has('message'))
<div class="alert alert-success">
{{ session()->get('message') }}
</div>
#endif
For more detail, you can read here
back() is just a helper function. It's doing the same thing as redirect()->back()
One way to do that is sending the message in the session like this:
Controller:
return redirect()->back()->with('success', 'IT WORKS!');
View:
#if (session()->has('success'))
<h1>{{ session('success') }}</h1>
#endif
And other way to do that is just creating the session and put the text in the view directly:
Controller:
return redirect()->back()->with('success', true);
View:
#if (session()->has('success'))
<h1>IT WORKS!</h1>
#endif
You can check the full documentation here: Redirecting With Flashed Session Data
I hope it is very helpful, regards.
All of the above are correct, but try this straight one-liner:
{{session()->has('message') ? session()->get('message') : ''}}
In Controller
return redirect()->route('company')->with('update', 'Content has been updated successfully!');
In view
#if (session('update'))
<div class="alert alert-success alert-dismissable custom-success-box" style="margin: 15px;">
×
<strong> {{ session('update') }} </strong>
</div>
#endif
You can use laravel MessageBag to add our own messages to existing messages.
To use MessageBag you need to use:
use Illuminate\Support\MessageBag;
In the controller:
MessageBag $message_bag
$message_bag->add('message', trans('auth.confirmation-success'));
return redirect('login')->withSuccess($message_bag);
Hope it will help some one.
Adi
in Controller:
`return redirect()->route('car.index')->withSuccess('Bein ajoute')`;
In view
#if(Session::get('success'))
<div class="alert alert-success">
{{session::get('success')}}
</div>
#endif
I am trying to Get Validation Errors on index.blade.php having issues:
When I fill both the fields then it goes well if i just put an Echo or Return in getLogin Controller.
When I just fill one field and it works good if i just put and echo or Return but not giving validation errors, with Validation Errors it only shows, "Something went Wrong"
Code for index.blade.php
<section class="mainWrap">
<div class="headingfirst"><img src="{{ URL::asset('css/des.png') }}" width="78"></div>
<div class="sedhead">Hey User!!!! Try to Login</div>
<div class="againtext">Sign In To Your Account</div>
<article class="FormContainer">
#foreach($errors as $error)
<div class="errors">{{ $error }} </div>
#endforeach
<img class="profile-img" src="{{ URL::asset('css/avatar_2x.png')}}">
{{ Form::open(array('class'=> 'SetMe')) }}
{{ Form::text('email',null, array('placeholder'=>'Email','class'=>'insi')) }}
{{ Form::password('password',array('placeholder'=>'Password','class'=>'dnsi')) }}
{{ Form::submit('Sign In', array('class'=>'SignIn')) }}
{{ Form::close() }}
</article>
</section>
Code for AuthController.php
<?php
class AuthController extends Controller{
public function GetLogin() {
return View::make('layouts.index');
}
public function LogInfo() {
$rules = array('email' => 'required','password' =>'required');
$validator = Validator::make(Input::all(),$rules);
if($validator->fails()){
return Redirect::route('login')
->withErrors($validator);
}
else{
}
}
}
Code for Routes.php
Route::get('login', array('uses'=>'AuthController#GetLogin' ));
Route::post('login', array('uses'=>'AuthController#LogInfo'));
even when i put the Auth Code it don't show anything except "Something goes wrong". but while working with just Echos it works properly
In validation failed statement,
You need to use return Redirect::to('login') instead of return Redirect::route('login').
In index.blade.php, it should be like -
#foreach($errors->all() as $error)
<div class="errors">{{ $error }} </div>
#endforeach
instead of
#foreach($errors as $error)
<div class="errors">{{ $error }} </div>
#endforeach
Also here is my suggestion. if you are currently developing an application using laravel, it is the best to enable debug. Open laravel/app/config/app.php and make sure 'debug' => 'true'. It will help you see what is detailed error messages with stack traces.
I am attempting to create a single page like application with Laravel 4. When the user arrives at the site, they should be prompted to log in. Once the user logs in, the view (not the URL) will switch and the user will be able to see information as if they are authenticated.
My HTML (if authroized should show "Auth" in h1, if not, it shows login form)
<div class="container">
#if(Auth::check())
<h1>Auth</h1>
#else
{{ Form::open(array('url'=>'login', 'method'=>'post')) }}
<div class="row">
<div class="col-xs-12">
<div class="form-group">
{{ Form::label('email', 'Email Address') }}
{{ Form::text('email', Input::old('email'), array('class'=>'form-control', 'placeholder'=>'example#test.com')) }}
</div>
</div>
</div>
<div class="row">
<div class="col-xs-12">
<div class="form-group">
{{ Form::label('password', 'Password') }}
{{ Form::password('password', array('class'=>'form-control')) }}
</div>
</div>
</div>
<div class="row">
<div class="col-xs-12">
{{ Form::submit('Log In', array('class'=>'btn btn-primary pull-right')) }}
</div>
</div>
{{ Form::close() }}
#endif
</div>
Controller
class SiteController extends BaseController {
public function getIndex()
{
return View::make('index');
}
public function postLogin() {
$email = Input::get('email');
$password = Input::get('password');
if (Auth::attempt(array('email'=>$email, 'password'=>$password)))
{
return Redirect::route('index');
}
}
}
My user model is the default that ships with Laravel 4. As of now, I am passing the Auth::attempt and getting the return Redirect::route('index');, but the #if(Auth::check()) doesn't seem to be firing. Instead it continues to show me the log in form. Am I doing something wrong here?
I don't see anything wrong here, but you need to be sure what's happening, it looks like your authenticated session is not sticking, but to be sure you could:
<?php
class SiteController extends BaseController {
public function getIndex()
{
Log::info('index - authed: '. Auth::check() ? 'yes' : 'no');
return View::make('index');
}
public function postLogin() {
$email = Input::get('email');
$password = Input::get('password');
if (Auth::attempt(array('email'=>$email, 'password'=>$password)))
{
Log::info('postLogin - attempt successful');
return Redirect::route('index');
}
Log::info('postLogin - error on attempt');
}
}
And then check your logs:
php artisan tail
