Empty array from controller to view - Laravel - php

Question

I'm new at Laravel, and I'm having some problems setting up an update for my application. I'm trying to pass an id from a view to a controller through routing to select an specific line, and after that I need to pass from the controller to another view. Idk where I'm doing wrong.
Here's my view code that passes de id:
#forEach($line as $data)
<tr>
<td><i class="icon ion-md-create"></i></td>
<td>{{$data->name}}</td>
<td>{{$data->time}}</td>
</tr>
#endforEach
Here's the route:
Route::get('/lineEdit/{id}', 'LineController#formEdit')->name('edit.line')->middleware('auth');
Here's the controller function from route:
public function formEdit($id){
$line = Line::find($id);
$lineUp = Line::select('*')
->where('id', $line)->get();
return view('lineEdit')->with('line', $lineUp);
}
And here's the piece of the view that will recieve the array:
<div class="card-body">
#forEach($line as $data)
<form method="POST" action="{{route('update.line', $data->id)}}">
#csrf
<div class="form-group row">
<label for="name" class="col-md-4 col-form-label text-md-right">
{{__('Name')}}
</label>
<div class="col-md-8">
<input type="text" name="name" class="form-control {{$errors->has('name') ? 'is-invalid' : ''}}" value={{$data->name}} required autofocus >
#if($errors->has('name'))
<span class="invalid-feedback" role="alert">
<strong>{{$errors->first('name')}}</strong>
</span>
#endif
</div>
</div>
<div class="form-group row">
<label for="time" class="col-md-4 col-form-label text-md-right">
{{__('Time')}}
</label>
<div class="col-md-8">
<input type="number" name="time" class="form-control {{$errors->has('time') ? 'is-invalid' : ''}}" value={{$data->time}} required >
#if($errors->has('time'))
<span class="invalid-feedback" role="alert">
<strong>{{$errors->first('time')}}</strong>
</span>
#endif
</div>
</div>
<div class="form-group row mb-0">
<div class="col-md-8 offset-md-4">
<button type="submit" class="btn btn-primary">
{{ __('Save') }}
</button>
</div>
</div>
</form>
#endforEach
</div>
Everything inside the forEach doesn't render. I can't see the problem.

Answer 1

In your controller:
public function formEdit($id){
$line = Line::find($id);
return view('lineEdit', compact('line'));
}
I use the compact method to send the $line variable to the view.
Also, if you want to get the Line model to edit you dont need this:
$lineUp = Line::select('*')->where('id', $line)->get();
you only need this to find your model:
$line = Line::find($id);

Answer 2

Try this in your controller:
public function formEdit($id){
$line = Line::find($id);
return View::make('lineEdit', compact('line'));
}
This should pass a variable $line to your view

Answer 3

Looks like the problem is in the controller code.
$line = Line::find($id);
returns you an object (just one object!) of class Line if a) $id is an integer b) $id is the primary key c) this key exists in the DB
So, either $line is null or a model object. The next query
$lineUp = Line::select('*')->where('id', $line)->get();
cannot be successful in either case.
As I understand your intent $id is just an attribute (because you expect to have a collection of objects). So, try
$lineUp = Line::select('*')->where('id', $id)->get();
