控制器

class KontenController extends Controller
{
    /**
     * Create a new controller instance.

berita_edit.blade.php 用于更新过程

<div class="card card-primary">
          <div class="card-header">
            <h3 class="card-title">Edit Berita</h3>
          </div>
          <!-- /.card-header -->
          <!-- form start -->
          <form action="{{route('berita.update')}}" method="POST">
          {{ csrf_field() }}
            {{method_field('PUT')}}  
          <div class="card-body">

              <div class="form-group">
                <label for="exampleInputPassword1">Username</label>
                <input type="text" class="form-control" name="username" placeholder="Username" value="{{ $berita->username }}">
              </div>
              <div class="form-group">
                <label for="exampleInputPassword1">Tanggal</label>
                <input type="date" class="form-control" name="tanggal" placeholder="Tanggal" value="{{ $berita->tanggal }}">
              </div>
              <div class="form-group">
                <label for="exampleInputPassword1">Judul</label>
                <input type="text" class="form-control" name="judul" placeholder="Judul" value="{{ $berita->judul }}">
              </div>
              <div class="form-group">
                    <label>Isi</label>
                    <textarea class="form-control" rows="3" name="isi" value="{{ $berita->isi }}" placeholder="Enter ..."></textarea>
                </div>

            <!-- /.card-body -->

            <div class="card-footer">
              <button type="submit" class="btn btn-primary">Submit</button>
            </div>
          </form>
        </div>

用于显示数据

 <div class="card-body table-responsive p-0">
            <table class="table table-hover text-nowrap">
              <thead>
                <tr>
                  <th>id_Berita</th>
                  <th>id_Kategori</th>
                  <th>Username</th>
                  <th>Tanggal</th>
                  <th>Judul</th>
                  <th>Isi</th>
                  <th colspan="2" style="text-align:left">Opsi</th>
                </tr>
              </thead>
              <tbody>
                @foreach($berita as $data)
                <tr>
                    <td>{{$data -> id_berita}}</td>
                    <td>{{$data -> id_kategori}}</td>
                    <td>{{$data -> username}}</td>
                    <td>{{$data -> tanggal}}</td>
                    <td>{{$data -> judul}}</td>
                    <td>{{$data -> isi}}</td>
                    <td>
                    <a class="btn btn-block btn-info" href="{{ route('berita.edit', $data -> id_berita) }}"?>Edit</a>
                    </td>
                    <td>
                    <a class="btn btn-block btn-info" href="#"?>Hapus</a>
                    </td>



                </tr>
                @endforeach
              </tbody>
            </table>
          </div>

Answer 1

您必须像这样更改动作

<form action="{{route('berita.update',['berita'=>$berita->id])}}" method="POST">


<a class="btn btn-block btn-info" href="{{ route('berita.edit', ['berita'=>$data->id_berita]) }}"?>Edit</a>

缺少[Route：berita.update]的必需参数
