php - Laravel 更新数组语法

Question

我在 Laravel 中通过 POST 执行记录更新数组时遇到问题。我已经捕获了数组中的所有帖子数据无法更新数组成就

<form action="{{'updateapp'}}" method="post">
<table>
<tr><td>
<input type="checkbox" class="id" name="id[]" value="{{ $quarter->id }}" />
<input type="text" name="achv[]" value="{{ $quarter->achievement }}">
</td></tr>
</table>
</form>

Controller :

public function foo(Request $request)
{
    $ids = $request->id;
    $achvs = $request->achv;
    DB::table('quarters')->whereIn('id', $ids)
    ->update(array(['achievement' => $achvs ]));   

    return redirect('evaluator');      
  }

Answer 1

由于您在表单中设置了 [] 数组，您可以按以下方式访问它

public function foo(Request $request)
{
    $ids = $request->id[0];
    $achvs = $request->achv[0];
    DB::table('quarters')->where('id', $ids)
    ->update(['achievement' => $achvs ]);   

    return redirect('evaluator');      
  }

如果要更新多行，请使用以下代码:

foreach($request->id as $key => $value){ 

      $quarters = Quarters::find($request->id[$key]); 
      $quarters->achievement = $request->achv[$key]; 
      $quarters->save(); 
}
