I have a form that has 10 inputs fields, I want to check if any of those input fields are empty. If they do are empty or have more than 2 characters I want to display only one error message. With my current code I show an error for each field that is empty. I don't want the user to see 10 error messages. I tried many other methods but doesn't seem to work.

I want the error message to say: 'Predictions can't be empty or have more than 2 characters'

The controller

 public function store(Request $request) max:2'
 ]);
 try 
 collect($requestData)
 ->each(function ($match, $key) 
 Prediction::create([
 'user_id' => auth()->id(),
 'match_id' => $key,
 'homeTeam' => $match['homeTeamName'],
 'awayTeam' => $match['awayTeamName'],
 'homeScore'=> $match['homeTeam'],
 'awayScore'=> $match['awayTeam'],
 'result' => false
 ]);
 );
 auth()->user()->participated = true; 
 auth()->user()->addPoint();
 auth()->user()->save();

 return redirect('/predictions')->with('success', 'Weekly prediction created, new predictions can be made every Tuesday!');

 catch(Exception $e) 
 return view('error.error');
 

 

My messages.blade.php file

@if(count($errors) > 0)
@foreach($errors->all() as $error)
 <div class="alert alert-red">
 $error
 </div>
 @endforeach 
@endif

@if(session('success'))
 <div class="alert alert-green">
 session('success')
 </div>
@endif

@if(session('error'))
 <div class="alert alert-danger">
 session('error')
 </div>
@endif

The view

@include('inc.messages')
!! Form::open(['method'=> 'POST', 'action'=>'PredictionController@store']) !!
@foreach($matches as $match)
 <tr>
 <td> <small style="opacity: 0.5; font-size: 10px;">$match->date->formatLocalized('%d %B %Y') <small></td>
 <td>$match->date->format('H:i')</td>
 Form::hidden('match[' . $match->match_id . '][homeTeamName]', $match->homeTeam )
 Form::hidden('match[' . $match->match_id . '][status]', $match->status )
 <td>$match->homeTeam</td>
 <td>$match->awayTeam</td>
 Form::hidden('match[' . $match->match_id . '][awayTeamName]', $match->awayTeam )
 <td style="width: 150px !important;"><div>Form::number('match[' . $match->match_id . '][homeTeam]' , '', [ 'class' =>'form-control-sm col col-sm-3']) <span class="ml-2" style="color: white;">-</span> Form::number('match[' . $match->match_id . '][awayTeam]' , '', ['class' =>'form-control-sm col col-sm-3 ml-2']) </div></td> 
 </tr>
@endforeach
Form::button('Submit', ['type' =>'submit', 'class' => 'submit-btn float-right mb-3']) 
!! Form::close() !!

Any tips?

I think you can do something like this:

@if($errors)
 <div class="alert alert-red">
 $errors->first() 
 </div> 
@endif

If there are errors, only show the first one.

You can retrieve the first error message for a given key as follows:

foreach ($errors->first('match.*') as $message) 
 //

For more information, check Laravel's documentation on Validation.

validate() method can take a third argument specifying the cusom error message.

To display just one, customized error message for any validation fail.

You can do:

 $this->validate(
 $request, 
 [ 
 'match.*.homeTeam' => 'required|max:2',
 'match.*.awayTeam' => 'required|max:2'
 ],
 ['match.*' => "Predictions can't be empty or have more than 2 characters"]);
