Undefined variable $user->username (Laravel 5.7) - php

I can't get the data from the database. Getting an error:
ErrorException (E_ERROR)
Undefined variable: user
(View:/Users/alex/Desktop/sites/tj/resources/views/user/submissions.blade.php)
Controller:
public function __construct()
{
$this->middleware('auth', ['except' => ['getById',
'getByUsername', 'submissions', 'comments', 'showSubmissions',
'showComments']]);
}
and
public function showSubmissions($username)
{
$user = new UserResource(
User::withTrashed()->where('username', $username)->firstOrFail(),
true
);
$submissions = SubmissionResource::collection(
Submission::whereUserId($user->id)
->withTrashed()
->orderBy('created_at', 'desc')
->simplePaginate(15)
);
return view('user.submissions', compact('user', 'submissions'));
}
View:
{{ $user->username }}
API:
Route::get('/user', 'UserController#getByUsername');
I need get information about user (username).
What is the problem and where is the error?

Based on your comment you have this route:
Route::get('/submission', function () {
return view('user.submissions');
});
When you are loading this view, you are not passing the user object to it. Then when the view is running, it is trying to access a variable that does not exist.
To fix this, you need to pass a variable to the view you are loading. For example, you could do something like this:
Route::get('/submission', function () {
return view('user.submissions', ['user' => auth()->user()]);
});
Note that you can change how you get the user instance depending on your use case. I am just getting the authenticated user to demonstrate the principle.

How to implement DataTable with parameter 'id' in Laravel (DataTables)?

I am trying to pass the ID value from the blade file into ajax so it the data table will be routed and will call the ProductActivities function in ProductController.
Here's my snippet code for show() function in ProductController:
public function show($id)
{
$product = Product::find($id);
$data = Product::with(['user_modify'], 'id', $product->user_modified)
->where('product_id', '=', $id)->first();
$category = Category::select('category_name')
->where('category_id', '=', $data->product_type)
->pluck('category_name')
->first();
if($data->count() > 0){
return view('product.view', compact('data', 'category'));
}else{
Toastr::error('Product cannot be retrieved.', 'Error');
return view('product.index');
}
}
And here's the snippet code of JavaScript for the DataTable initialization in view.blade.php file:
#push('js')
<script>
$(function () {
$("#prod_log_tbl").DataTable({
responsive:true,
stateSave:false,
scrollY:true,
autoWidth: false,
ajax: {{ url('product/activities', [Request::segment(3)]) }},
order:[0, 'desc'],
searchable: false,
sortable:false,
fixedColumns: true
});
});
</script>
#endpush
line of code for route in web.php:
Route::get('product/activities/{id}', 'Master\ProductController#ProductActivities')->name('product/activities/{id}');
snippet code for the ProductActivities() function in ProductController:
public function ProductActivities($id)
{
$dataAct = Activity::all()->where('subject_id', '=', $id);
return Datatables::of($dataAct)->make(true);
}
And here's the result of my current progress:
In the screenshot of result the URL that ajax shows has additional values after the ID which I think causes of the DataTable error.
I don't know How I am getting this error? How can I implement the passing of ID from the view blade file through DataTable ajax into the ProductController?
P.S. I use Yajra/DataTable package for Laravel.
I think you do not need php echo in you Ajax url, route helper syntax is
{{ route('routeName', ['id' => 1]) }}
you need route name and parameter, another way is using url helper
{{ url('product/activities/', [Request::segment(3)]) }}
Beside this if you want to use model refer documentation, using first() will give you only one object, you need a collection, better considering get().

Laravel Undefined variable: intent Facade\Ignition\Exceptions\ViewException

I tried looking for all the possible solutions none of it worked and this is very basic trying to send data from a controller to view in Laravel.
Paymentcontroller
public function payment() {
$plans =[
'Basic' => "Monthly"
];
$intent = $user->createSetupIntent();
return view('pages.subscription', compact('intent', 'plans'));
}
PageController
public function index(string $page)
{
if (view()->exists("pages.{$page}")) {
return view("pages.{$page}");
}
return abort(404);
}
View pages.subscription
<div>
{{ $intent }}
</div>
route
Route::get('{page}', ['as' => 'page.index', 'uses' => 'PageController#index']);
Route::get('/subscription', 'PaymentController#payment');
This makes the page work but doesn't display the data
Move Route::get('/subscription', 'PaymentController#payment'); before Route::get('{page}',.... (it should be your last route in the list).
Currently when you call /subscription endpoint you are calling PageController#index, but it doesn't contain logic of your PaymentController#payment and doesn't pass any data to view.

How to pass variables needed in view through redirect route in laravel?

I have modified default auth method in controller which redirects user after custom login to set_password page. The problem is I can redirect it well to the desired page but I need to simultaneously pass two dynamic variables which are returned through querying database, which I am unable to pass with redirect.
My modified controller method is as follows:-
protected function authenticated(Request $request, $user)
{
$activated_up = User::where('id_user',Auth::user()->id_user)
->where(function($query) {
$query->where('activated_up', '=', '1')
->orWhere('activated_up', '=','0');
})
->get(['activated_up']);
$showuser = UserProfile::where('id_user',Auth::user()->id_user)->first();
return redirect()->route('set_password',['activated_up' => $activated_up, 'showuser' => $showuser]);
}
I know that to pass a variable to an view, I need to use the compact method like follows:-
return view('set_password', compact('activated_up', 'showuser'); but it cant be done with redirect.
The way I have redirected means I am passing parameters to route in the controller method, but I need to pass variables to the redirected view instead of parameters. How to achieve that?
protected function authenticated(Request $request, $user)
{
$activated_up = User::where('id_user',Auth::user()->id_user)
->where(function($query) {
$query->where('activated_up', '=', '1')
->orWhere('activated_up', '=','0');
})
->get(['activated_up']);
$showuser = UserProfile::where('id_user',Auth::user()->id_user)->first();
return redirect()->route('set_password',['activated_up' => $activated_up, 'showuser' => $showuser]);
}
you can use With
return redirect()->route('set_password')->with('data', ['some kind of
data']);
in your view
#if (session::has('data'))
The data is {{ session::get('data') }}
#endif
Tried as described in the answer by Kuldeep Mishra but could not achieve it though, anyways I found a workaround to achieve my desired output. What I did is changed my authenticated method to this:-
protected function authenticated(Request $request, $user)
{
return redirect()->route('set_password');
}
I only redirected to the set_password route from the above method and made new method in the controller to show the view with the compacted variables like this:-
public function setPasswordForm(Request $request)
{
$activated_up = User::where('id_user',Auth::user()->id_user)
->where(function($query) {
$query->where('activated_up', '=', '1')
->orWhere('activated_up', '=','0');
})
->get(['activated_up']);
$showuser = UserProfile::where('id_user',Auth::user()->id_user)->first();
return view('set_password', compact('activated_up', 'showuser'));
}
And a small change in route web.php file:-
Route::get('/set_password', 'Controller#setPasswordForm')->name('set_password');
So finally I was able to redirect to desired page with the desired view loaded with dynamic variables.

Call to undefined method appends()

I created a filter for db table, but filtration just work for first page
I try this code in controller
public function index(Request $request)
{
$user=User::orderBy('created_at', 'ASC');
if($request->get('search'))
{
if ($request->get('type')) {
$user->where('type', $request->get('type'));
}
if ($request->get('id')) {
$user->where('id', (integer)$request->get('id'));
}
if ($request->get('first_name')) {
$user->where('first_name', $request->get('first_name'));
}
if ($request->get('email')) {
$user->where('email', $request->get('email'));
}
}
$users = $user->paginate(20);
$user->appends(['search' => $request->get('search')]);
return view('admin.user.index', compact('users'));
}
But I get this error
Call to undefined method Illuminate\Database\Query\Builder::appends()
How I can fix this error or how I can make filter works with all pages ?
As I can see you have used following line and paginate the user data in users
$users = $user->paginate(20);
So you need to use users variable instead of user
$users->appends(['search' => $request->get('search')]);

Sending route parameter in form

I am trying create form (defined like this: link) but I dont know what is $user->id in syntax
echo Form::open(array('route' => array('route.name', $user->id)))
When I use it I have error:
Undefined variable: user (View: ...)
Could anyone explain ?
You probably should pass your user to the view:
public function index()
{
return view('your-view-name')->with('user', Auth::user());
}
