Question

I have an edit account page, and I want to put the value in the database as selected :

@foreach($all_orga as $val)
    @if($val->id_organisme==13)
        <OPTION selected value="{{$val->id_organisme}}">{{$val->nom}}</OPTION>
    @else
        <OPTION value="{{$val->id_organisme}}">{{$val->nom}}</OPTION>
    @endif
@endforeach

This works fine as it displays the list but nothing is "selected", so I edited it using $compte->id_organisme, which is equal 3 in my test:

@foreach($all_orga as $val)
    @if($val->id_organisme == $compte->id_organisme)
        <OPTION selected value="{{$val->id_organisme}}">{{$val->nom}}</OPTION>
    @else
        <OPTION value="{{$val->id_organisme}}">{{$val->nom}}</OPTION>
    @endif
@endforeach

It still displays the list, but again, nothing "selected".

Informations :

dd($all_orga) 

    EQUALS

array:12 [▼
  0 => {#566 ▼
    +"id_organisme": 2
    +"nom": "Orga 1"
  }
  1 => {#515 ▶}
  2 => {#565 ▶}
  3 => {#564 ▶}
  4 => {#563 ▶}
  5 => {#562 ▶}
  6 => {#561 ▶}
  7 => {#560 ▶}
  8 => {#559 ▶}
  9 => {#558 ▶}
  10 => {#557 ▶}
  11 => {#556 ▶}
]

dd($compte->id_organisme)

    EQUALS

3

Here, the 3 value seems to be selected :

@foreach($all_orga as $val)
    @if($val->id_organisme == $compte->id_organisme)
        <OPTION selected value="{{$val->id_organisme}}">{{$val->nom}} {{$val->id_organisme}} {{$compte->id_organisme}}</OPTION>
    @else
        <OPTION value="{{$val->id_organisme}}">{{$val->nom}} {{$val->id_organisme}}</OPTION>

        @endif
    @endforeach

我建议你让Laravel做重物。即使它不是核心的一部分，Laravel也有一个很好的表单构建器，它被转移到一个单独的项目中：Laravel Collective。并且使用它可以获得很多其他不错的功能（例如Form model binding）。

此外，您可能希望开始使用collections而不是数组。如果我在Laravel中写这个，我会按照以下方式做一些事情：

/**
 * Edit account action
 *
 * @file YourController
 */
public function editAccountAction() {
    return view('edit', [
        'compte'   => $compte,
        'all_orga' => collect($all_orga),
    ]);
}

在你看来：

// use the collection's pluck method to build the array of options for the dropdown
{!! Form::select('name', $all_orga->pluck('id_organisme', 'nom'), $compte->id_organisme) !!}
