實作laravel的CRUD

主要參考影片而來的~
目前我的新增和修改都寫在update裡~
(新增功能寫兩個都註解掉了)


web.php
Route::view('/todo','index');
Route::get('/todo', 'TodoController@index');
Route::post('/todo', 'TodoController@update');

Route::delete('/todo/{todo}', 'TodoController@destroy');

Todo.php
<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Todo extends Model
{
protected $fillable = ['title'];
//$todo = 'title';
}

TodoController.php
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Todo;

class TodoController extends Controller
{
    public function index()
    {
    $todos = Todo::all();
    //dd($todos);
    return view('index', ['todos'=>$todos]);
    }

    public function update(Request $request)
    {
    // $todo = new Todo();
    // $todo->title = $request->title;
    // $todo->save();

    // $request->validate([
    // 'title' => 'required|min:3'
    // ]);
    // $todo = Todo::create($request->all());

        //return $todo;

        $id=$request->input('id');
        $title=$request->input('title');

        $staff = Todo::find($id);
        $staff->title = $title;
        $staff->save();

        //$todo = Todo::create(['title'=>$request->title]);

        return redirect('todo');
    }

    public function destroy(Request $request, Todo $todo)
    {
    $todo->delete();
    return redirect('todo');
    }
}

index.blade.php
<!-- @if ($errors->has('title'))
<strong>{{ $errors->first('title') }}</strong>
@endif
 -->
@foreach($todos as $todo)
<p>
{{ $todo->id.','.$todo->title }}

<form action="todo/{{ $todo->id }}" method="POST">
{{ csrf_field() }}
{{ method_field('DELETE') }}
<input type="submit" value="delete">
</form>
</p>
@endforeach

<form action="todo" method="POST">
{{ csrf_field() }}
<input type="text" placeholder="請輸入" name="id">
<input type="text" placeholder="請輸入" name="title">
<input type="submit">
</form>
