Call to a member function save() on null: PROBLEM IN UPDATING - arrays

Question

I cannot update my record using foreach
ScoreController.php
public function updateScore(Request $request, $id)
{
foreach ($request->score as $key => $id) {
$scores = Score::find($request->score[$key]);
$scores->save();
}
//dd($request->all());
return redirect('/tabulation')->with('status', 'Score added!');
}
Blade
#foreach ($scores as $score)
<label for="{{$score->id}}" value="{{$score->id}}"></label>
<input type="text" name="score[]" value="{{$score->score}}"/>
#endforeach

Answer 1

First of all, <label> elements do not have a value attribute:
<label for="{{ $score->id }}" value="{{ $score->id }}"></label>
That value="{{ $score->id }}" does nothing, and isn't sent to the server. If you want to send the score's ID to the server, pass that in your input:
#foreach($scores AS $score)
<input type="text" name="scores[{{ $score->id }}]" value="{{ $score->score }}"/>
#endforeach
Next, in your controller, access your variables correctly:
foreach($request->input("scores") AS $id => $scoreValue){
$score = Score::find($id);
$score->score = $scoreValue;
$score->save();
}
The reason you're getting Call to a member function save() on null is that you're trying to find a Score that has an id of whatever $score->score contains. You're not passing or referencing the id correctly.
