#if ((count($errors) > 0) and (session("NON")) )
$('#ModalCreate').modal('show');
#endif
</script>
<script type="text/javascript">
#if ((count($errors) > 0) and (session("NO")) )
$("#ModalEdit{{$courrier->id}}").modal('show');
#endif
</script>
#endsection
#section('contenu')
<div class="x_panel">
<div class="x_title">

I tried to put the edit modal in the listeCourriersBog.blade.php but when I click, only the last courrier get updated!
Don't know how to fix that
