我正在使用 laravel 5 并且我有一个更新/编辑表单，其中包含一个组合框。但是我不能设置我的组合框值取决于数据库中的内容。你知道怎么做吗？
这是我的控制器：
public function ubahsurat(Request $request)
{
Surat::where('nomor_surat', '=', $request['nomor_surat'])->update(
['id_jenis_surat' => $request['id_jenis_surat']],
return redirect('/');
}
This is the view:
这是视图：
<div class="col-sm-9">
<select name="id_jenis_surat" class="form-control">
<option></option>
@foreach($jenis_surat as $js)
<option value="{{ $js->id_jenis_surat }}" > {{ $js->jenis_surat }} </option>
@endforeach
</select>
</div>

All you need to do is set selected="selected"on the item which is active.
您需要做的就是selected="selected"在活动的项目上进行设置。
<option value="{{ $js->id_jenis_surat }}" {!! ($conditionForSelected ? "selected=\"selected\"" : "") !!}> {{ $js->jenis_surat }}</option>
Replace $conditionForSelectedwith whatever it is that determines if $js->id_jenis_suratis the current item that is selected.
替换$conditionForSelected为确定是否$js->id_jenis_surat选择当前项目的任何内容。
Your view is showing us the update code, not the view code.
您的视图向我们显示了更新代码，而不是视图代码。

You can do like this:
你可以这样做：
<div class="col-sm-9">
<select name="id_jenis_surat" class="form-control">
<option></option>
@foreach($jenis_surat as $js)
<option value="{{ $js->id_jenis_surat }}" @if($combobox_value_from_database==$js->id_jenis_surat) selected="selected" @endif> {{ $js->jenis_surat }} </option>
@endforeach
</select>
Note: I would encourage you to use Laravel Form Builders. so you can avoid handling these type of issues.
注意：我鼓励您使用 Laravel 表单构建器。这样您就可以避免处理这些类型的问题。
