   @break
   @elseif($favprds[$i]->id != $pro->id && $i == count($favprds)-1)
<div class="tinv-wishlist-clear">
  <a href="{{ url('add-to-favorie/'.$pro->id) }}"><i class="klbth-icon-heart-1"></i></a>
</div>
@endif
@endfor
@if(count($favprds) == 0)
  <div class="tinv-wishlist-clear">

Answer 1

it seems that te way i access the products is the wrong way thought i still have to test if the there's a probleme with adding to the favorite product

$currentTime = date("Y-m-d");
if ($favorie = auth()->user()->favorie ?? false) {
 $favprds = $favorie->produits;
 } else {
   $favprds = [];
}
