but what I get is this: enter image description here

MY CODE : Controller

$years = Year::with('employeeData')->get();

    $indicators = Indicator::all();
 return view('sustainability-data.input-data', compact('years', 'indicators'));

View

@foreach($employees as $index=>$employee)
                    <tr>
                        <td>{{$employee->name}}</td>
                        @foreach($years as $year)
                            <td>
                                @foreach($year->employeeData as $datum)
                                        @if($datum->employee_id == $employee->id)
                                            {!! Form::text('row[$index][value]' ,$datum->value,['class' => 'form-control']) !!}
                                        @endif

                                @endforeach
                            </td>

    It looks like the problem is with the structure of @foreach($year->employeeData as $datum). I'm assuming that if an employee doesn't already have data for a given year then @if($datum->employee_id == $employee->id) will never evaluate to true. If this is the case then then the code that outputs the form field won't run.

    The simplest way of converting what you currently have is to replace the @foreach with something like the following:

    @if($year->emplyeeData()->where('employee_id', $employee->id)->count())
        {!! Form::text('row[$index][value]', $year->emplyeeData()->where('employee_id', $employee->id)->get()->value, ['class' => 'form-control']) !!}
    @else
        {!! Form::text('row[$index][value]', '', ['class' => 'form-control']) !!}
    @endif
    

    Please note, I've made a few guesses of how your models are set up so this code may need to be adapted.

    I would also consider removing this logic from the view and maybe adding a method to your Employee model called getDataForYear which returns the value or an empty string.
