如何在 laravel 的数据库中更新新的选中项

Question

我可以请求选中的并查看它们，但我不能更新它。

在数据库中，我有表 types 和类型 2 列：rijbewijsnummer, rijbewijstype

如何更新数据库中新检查的？

我的控制器中的功能

public  function Modify (Request $request) {



   $user = Auth::user();
   $type = Type::all();

   $user->rijbewijsnummer = Request::input('rijbewijsnummer');
   $type->rijbewijstype = Request::input('rijbewijstype');




   $user->save();




   return redirect()->route('home');

   }

我觉得我做错了什么

public function details(Request $request)
{
    $user = Auth::user();
    $types = Type::where("rijbewijsnummer", "=", $user->rijbewijsnummer)->get();


    foreach ($types as $type)
    {



        $rijbewijstype[]= $type->rijbewijstype;



    }

    $user->save();






    return view('details', compact('user','rijbewijstype', 'types'));

}

查看：

<div class="col-md-6">
    <div name="rijbewijstype">
        <input  type="checkbox"  name="rijbewijstype[]" @foreach ($types as $type) @if ($type->rijbewijstype == "AM")) checked  @endif @endforeach value="AM" >AM</input>

Answer 1

简短的回答，您没有将“rijbewijsnummer”保存在类型表中。

长答案（使用 cmets 解释代码及其作用）：

 $user = Auth::user();
   $type = Type::all();

// Here you set the attribute rijbewijsnummer to the input value.
   $user->rijbewijsnummer = Request::input('rijbewijsnummer');

// Here you set the selected type as an attribute on the type object.
   $type->rijbewijstype = Request::input('rijbewijstype');

// Here you save the user (this means you can now get the rijbewijsnummer from the user table)
   $user->save();

// But you don't save the Type you selected, 
// let alone add the rijbewijsnummer to it, 
// so even if you did save it, you'd just get an empty rijbewijsnummer
// and rijbewijstype would be filled. 
// (or rather, overwrite the other empty rijbewijsnummer field with the new rijbewijstype, if you allow rijbewijsnummer to be empty)

   return redirect()->route('home');

您可以通过更改以下行来解决此问题。

$type->rijbewijstype = Request::input('rijbewijstype');

到

// Creates a new entry in Types, using the rijbewijstype and rijbewijsnummer.
$type->create(['rijbewijstype' => Request::input('rijbewijstype'), 'rijbewijsnummer' => Request::input('rijbewijsnummer'));

我假设您希望为不同类型保存相同 rijbewijsnummer 的多个条目。

您还使用了一些低效的代码，而且我认为您的数据库结构没有经过深思熟虑。但这超出了这个问题的范围。 如果您的代码完全正常工作，您可以随时寻求帮助以改进代码审查堆栈上的代码。
