undefined index on empty array laravel 5 - php

Question

Fellow coders,
It might be a stupid question but I really am stuck on this part in my application.
I am making an hourregistration system for the company i'm an intern at. What I have done is creating a delete button in my application that deletes a record with the click of a simple button. Yet what I did was to delete all the visible records in the table I created that shows all the registrations.
When I deleted the final record I got an error of "undefined index hourregistration".
public function index()
{
$hoursregistrations = Hoursregistration::latest()->get();
$user_id = Sentinel::getUser();
$project_id = Project::pluck('description', 'id');
$company_name = Company::where('status','client')->pluck('company_name', 'id');
$activity_name = Subproject::pluck('id');
//dd($hoursregistrations);
return view('hoursregistrations.index', compact('hoursregistrations', 'user_id', 'project_id',
'activity_name', 'company_name'));
}
I think the problem lies at
$hoursregistrations = Hoursregistration::latest()->get();
Because I'm trying to get the latest value of the registration but there is none right?
Now i'm wondering how I could still show my view without breaking my inserting and/or viewing portion of the app.
#foreach ($hoursregistrations as $hoursregistration)
<tr>
<td hidden>{{ $user_id->first_name }}</td>
<td >{!! App\Project::getCompanyName($hoursregistration->project_id) !!} - {!! \App\Subproject::getTaskTitle($hoursregistration->subproject_id)!!}</td>
<td>{!! $hoursregistration->note !!}</td>
<td>{!! \App\Helpers::dateFormat($hoursregistration->date) !!}</td>
<td>{!! $hoursregistration->hours !!}</td>
<td>
<button id="btn-edit" name="btn-edit" class="btn btn-warning btn-xs btn-detail open-modal" value="{{$hoursregistration->id}}">Edit</button>
<form action="hoursregistrations/{{ $hoursregistration->id }}/delete" method="POST">
{{ csrf_field() }}
{{ method_field('DELETE') }}
<button id="btn-delete" type="submit" name="btn-delete" class="btn btn-danger btn-xs btn-delete delete-hoursregistration" value="{{ $hoursregistration->id }}">Delete</button>
</form>
</td>
</tr>
#endforeach
This is the foreach loop that shows the data in the index.blade.php view
I would love some help so I can continue finishing this application
public function index()
{
$hoursregistrations = Hoursregistration::latest()->get();
$user_id = Sentinel::getUser();
$project_id = Project::pluck('description', 'id');
$company_name = Company::where('status','client')->pluck('company_name', 'id');
$activity_name = Subproject::pluck('id');
//dd($hoursregistrations);
return view('hoursregistrations.index', compact('hoursregistrations', 'user_id', 'project_id',
'activity_name', 'company_name'));
}

Answer 1

Everything is about s or not s.
The error you are talking about is because you have an occurrence of $hoursregistration (without s) before or after the #foreach of your view. The solution is to check and remove occurrence of $hoursregistration outside your loop:
// You can't use $hoursregistration before
#foreach ($hoursregistrations as $hoursregistration)
{{-- ... do what you want with $hoursregistration --}}
#endforeach
// You can't use $hoursregistration after
I am sure there is a confusion (typo) between $hoursregistration, $hoursregistrations and $hourregistration (the confusion is even in your post VS comment)

Answer 2

you can use if here if $hoursregistrations exists then it populate data else nothing happen
#if($hoursregistrations)
#foreach ($hoursregistrations as $hoursregistration)
<tr>
<td hidden>{{ $user_id->first_name }}</td>
<td >{!! App\Project::getCompanyName($hoursregistration->project_id) !!} - {!! \App\Subproject::getTaskTitle($hoursregistration->subproject_id)!!}</td>
<td>{!! $hoursregistration->note !!}</td>
<td>{!! \App\Helpers::dateFormat($hoursregistration->date) !!}</td>
<td>{!! $hoursregistration->hours !!}</td>
<td>
<button id="btn-edit" name="btn-edit" class="btn btn-warning btn-xs btn-detail open-modal" value="{{$hoursregistration->id}}">Edit</button>
<form action="hoursregistrations/{{ $hoursregistration->id }}/delete" method="POST">
{{ csrf_field() }}
{{ method_field('DELETE') }}
<button id="btn-delete" type="submit" name="btn-delete" class="btn btn-danger btn-xs btn-delete delete-hoursregistration" value="{{ $hoursregistration->id }}">Delete</button>
</form>
</td>
</tr>
#endforeach
#endif
i think this might help
