Question

Controller
public function getScore(Request $request, $id)
{
// $scores = Criteria::find($id);
$contestants = Contestant::find($id);
foreach ($request->criteria as $id => $criteria){
$criteriaModel = Score::find($id);
$scores = new Score();
$scores->judge_name = $request->input('judge_name');
$scores->contestant = $contestants->name;
$scores->criteria = $criteriaModel->criteria;
$scores->score = $scores->score;
$scores->save();
}
return redirect('/tabulation')->with('status', 'Score saved!');
}
Blade
#foreach ($criterias as $criteria)
<div class="form-group col-md-6">
<label for="{{$criteria->name}}">{{$criteria->name}} </br> (0 - {{$criteria->points}})</label>
<input type="text" name="criteria[{{$criteria->id}}][criteria]" value="{{$criteria->name}}" hidden>
<input type="text" name="score[{{$criteria->id}}][score]" class="form-control" placeholder="Input score" required>
</div>
#endforeach

Answer 1

Form field names can contain brackets to store multiple properties for a single name:
#foreach ($criterias as $criteria)
<div class="form-group col-md-6">
<label for="{{$criteria->name}}">{{$criteria->name}} </br> (0 - {{$criteria->points}})</label>
<input type="text" name="criterias[{{$criteria->id}}][name]" value="{{$criteria->name}}" hidden>
<input type="text" name="criterias[{{$criteria->id}}][points]" class="form-control" placeholder="Input score" max="{{$criteria->points}}" name="score" required>
</div>
#endforeach
The above form would result the $request->criterias variable containing the following value:
array:2 [▼
1 => array:2 [▼
"name" => "test"
"points" => "dd"
]
2 => array:2 [▼
"name" => "tes22t"
"points" => "sdsd"
]
]
This value can be used in the controller for creating multiple scores:
foreach ($request->criterias as $id => $criteria){
$criteriaModel = Criteria::find($id);
$scores = new Score();
$scores->judge_name = $request->input('judge_name');
$scores->contestant = $contestants->name;
$scores->criteria = $criteriaModel->name;
$scores->score = $criteria->points;
$scores->save();
}

Answer 2

First of all you have to change the name of your input to be an array like so:
<input type="text" name="criteria[]" value="{{$criterias->name}}" hidden>
and in your controller you have to loop through the inputs:
foreach ($request->input('criteria') as $criteria){
$scores = new Score();
$scores->judge_name = $request->input('judge_name');
$scores->contestant = $contestants->name;
$scores->criteria = $request->input('criteria');
$scores->score = $request->input('score');
$scores->save();
}
