Hello.

There is a code that displays all the elements from the database, during the output checks for the presence of a value in the database:

<div class="tickets-places"> {{$i = 1}} @foreach($tickets as $t) @if($t->number != $i) <div class="one-place" id="game-place-{{$i}}" onclick="setplace(2,1, {{$i}}, {{$user->id}});"> <span>{{$i}}</span> </div> @else <div class="one-place" id="game-place-" onclick="setplace(2,1, {{$i}}, {{$user->id}});"> <span>test</span> </div> @endif {{$i = $i+1}} @endforeach </div>

If the value is in the database, then displays test. It turns out that if @if works, then it changes the first elements or if the value of $t->number is set in two lines in the database, it still displays test only for the first value. How can this be solved?

    To get the current index when traversing an array, better use the $loop variable here an article will help you with it https://mattstauffer.co/blog/the-new-loop-variable-in-laravel-5-3

    on your problem, I think this is due to the fact that you always have $i before the start of the cycle. I can’t be more precise, because I don’t know that when iterating a cycle in the $t->number variable

      Your option:

       <div class="tickets-places"> @php $i = 1; @endphp @foreach($tickets as $t) @if($t->number != $i) <div class="one-place" id="game-place-{{$i}}" onclick="setplace(2,1, {{$i}}, {{$user->id}});"> <span>{{$i}}</span> </div> @else <div class="one-place" id="game-place-" onclick="setplace(2,1, {{$i}}, {{$user->id}});"> <span>test</span> </div> @endif @php $i += 1; @endphp @endforeach </div>

      But it is better to test this option:

       <div class="tickets-places"> @foreach($tickets as $t) @if($t->number != $loop->iteration) <div class="one-place" id="game-place-{{ $loop->iteration }}" onclick="setplace(2,1, {{ $loop->iteration }}, {{ $user->id }});"> <span>{{ $loop->iteration }}</span> </div> @else <div class="one-place" id="game-place-" onclick="setplace(2,1, {{ $loop->iteration }}, {{ $user->id }});"> <span>test</span> </div> @endif @endforeach

      ps if your $t->number starts with 1 use $loop->iteration if with 0 then $loop->index
