Question

我正在试图将数据更新到数据库，我终于摆脱了所有错误，所以现在它正确地重定向没有错误但它没有在网站或数据库上更新。

非常感谢任何帮助，谢谢！

web.php

Route::put('/my-saved-routes/{myroute_id}', 'MyroutesController@update');

MyroutesController.php

public function update(Request $request, $id)
{    
     $Myroutes = Myroutes::find($id);
     $Myroutes->start = $request->input('start');
     $Myroutes->end = $request->input('end');
     $Myroutes->waypoints = $request->input('waypoints');

     $Myroutes->save();

     return redirect('/my-saved-routes');
}

Myroutes.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

use Illuminate\Http\Request;

class Myroutes extends Model
{
    protected $fillable = [
        'myroute_id',
        'user_id',
        'start',
        'end',
        'waypoints'
    ];

    protected $primaryKey = 'myroute_id';

}

Answer 1

你可以这样做

Myroutes::where('id', $id)
                ->update(['start' => $request->input('start'),
                         'end'=>$request->input('end'),
                         'waypoint'=>$request->input('waypoints')]
                        );

Answer 2

尝试

<form method="put" action="/my-saved-routes">

更新

<form method="post" action="/my-saved-routes/{{ $myroute->myroute_id }}">

Answer 3

尝试以下操作：

<form class="form" method="post" action="/my-saved-routes/{{ $$myroute->myroute_id) }}">
  {{ method_field('patch') }}
  {{ csrf_field() }}
