如何使用 laravel 在变量中发送查询？

Question

我有这个功能来注册我的用户

protected function validator(array $data)
{
    return Validator::make($data, [
        'name' => ['required', 'string', 'max:255'],
        'apellido' => ['required', 'string', 'max:255'],
        'idop' => ['required', 'string', 'max:6', 'unique:users'],
        'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
        'password' => ['required', 'string', 'min:8', 'confirmed'],
        'cedula' => ['required', 'int'],
        'fecha_nacimiento' => ['required', 'date'],
        'fecha_ingreso' => ['required', 'date'],
        'extension' => ['required', 'int'],
        'movil' => ['required', 'int'],
        'tel_hab' => ['required', 'int']
    ]);

}

我想在变量 ($generos) 中发送此查询以生成 select

$generos = DB::table('tbl_lista_generos')
            ->select('id','genero')
            ->get();

我该怎么做？

Answer 1

根据评论，您想将查询结果发送到视图。所以，

在你的控制器函数中做：

return view('generos.index', [
      'generos' => DB::table('tbl_lista_generos')->select('id','genero')->get()
]);

在视图中：

<select class='' name='select_form_generos'>
<option value=''>select genero</option>
@foreach ($generos as $genero)
     <option value='{{ $genero->id }}'>{{ $genero->genero}}</option>
@enforeach
</select>

希望对您有所帮助！

您可以使用以下方式将变量从 controller 传递到 view：

方式 1

$generos = DB::table('tbl_lista_generos')
            ->select('id','genero')
            ->get();
return view("index", compact("generos "));

方式2

 $generos = DB::table('tbl_lista_generos')
                ->select('id','genero')
                ->get();
 return view("index", ["generos" => $generos]);

方式 3

 $generos = DB::table('tbl_lista_generos')
                ->select('id','genero')
                ->get();
 return view("index")->with(["generos" => $generos]);

On your view file::

 <select name="genero">
  <option value=''>select</option>
   @foreach ($generos as $genero)
     <option value="{{ $genero->id }}">{{ $genero->name}}</option>
   @enforeach
</select>
