<?php 

namespace App\Http\Controllers; 

use \App\Http\Requests\contactsrequest; 
use App\contacts; // contacts model included using "use" 


class contactscontroller extends Controller 
{ 
    /** 
    * Display a listing of the resource. 
    * 
    * @return \Illuminate\Http\Response 
    */ 
    public function index() 
    { 
     //Display Data 
     //find contact by contacts model 
     // use model contacts and include the use App\contacts model 
     // variable contact holds all values of contacts table 
     $contact=contacts::all(); // contavt 
     return view('contacts.index',['contacts'=>$contact]); 
    } 

    /** 
    * Show the form for creating a new resource. 
    * 
    * @return \Illuminate\Http\Response 
    */ 
    public function create() 
    { 
     // 
     return view('contacts.create'); 
    } 

    /** 
    * Store a newly created resource in storage. 
    * 
    * @param \Illuminate\Http\Request $request 
    * @return \Illuminate\Http\Response 
    */ 
    public function store(contactsrequest $request) 
    { 
     //contacts model 
     contacts::create($request->all()); 
     return redirect()->route('contacts.index')->with('message', 'Contacts has been added successfully'); 
    } 

    /** 
    * Display the specified resource. 
    * 
    * @param int $id 
    * @return \Illuminate\Http\Response 
    */ 
    public function show($id) 
    { 
     // 
    } 

    /** 
    * Show the form for editing the specified resource. 
    * 
    * @param int $id 
    * @return \Illuminate\Http\Response 
    */ 
    public function edit(contacts $contacts) 
    { 
     // 

     return view('contacts.edit', compact('contacts')); 
    } 

    /** 
    * Update the specified resource in storage. 
    * 
    * @param \Illuminate\Http\Request $request 
    * @param int $id 
    * @return \Illuminate\Http\Response 
    */ 
    public function update(contactsrequest $request, contacts $contacts) 
    { 
     // 
     $contacts->update($request->all()); 
     return redirect()->route('contacts.index')->with('message', 'Contacts has been updated successfully'); 

    } 

    /** 
    * Remove the specified resource from storage. 
    * 
    * @param int $id 
    * @return \Illuminate\Http\Response 
    */ 
    public function destroy($id) 
    { 
     // 
    } 
} 





The edit form is below 
<!-- Home page to Display contacts --> 
@extends('master') 

@section('content') 
<div class="container"> 
<div class="row"> 
    <div class="col-md-10 col-md-offset-1"> 
<div class="panel panel-primary"> 
    <div class="panel-heading"> 
    <h3 class="panel-title">Update Contacts</h3> 
    </div> 
    <div class="panel-body"> 

      <!-- $contacts is object --> 
      {{Form::model($contacts, array('route'=>['contacts.update', $contacts->id],'method'=>'POST'))}} 
    <!-- input name, value is null, the parameters e.g class, placeholder etc --> 
     <div class="form-group"> 
     {{Form:: label('Name','Enter name') }} 
     {{Form:: text('Name',null, ['class'=>'form-control','placeholder'=>'Enter Name']) }} 
     </div> 
     <div class="form-group"> 
     {{Form:: label('Phone','Mobile Number') }} 
     {{Form:: text('Phone',null, ['class'=>'form-control','placeholder'=>'Enter Mobile Number']) }} 
     </div> 
     <div class="form-group"> 
     {{Form:: label('Email','Email Address') }} 
     {{Form:: email('Email', null, ['class'=>'form-control','placeholder'=>'Enter Email Address']) }} 
     </div> 

     <div class="form-group"> 
      {{ Form::button('Update',['class'=>'btn btn-primary', 'type'=>'submit'])}} 
      | 
     <a href="{{route('contacts.index')}}" class="btn btn-warning btn-sm"> <i class="fa fa-plus-square fa-lg" aria-hidden="true" style="border: none;"></i>Back</a> 
      </div> 
     {{Form:: close() }} 

    </div> 
    </div> 

</div>

Answer 1

versuchen Sie dies in Ihrem Controller

Answer 2

Ihrer Sicht erwartet das Modell $ Kontakte aufgerufen werden, so ändern Sie Ihre bearbeiten() -Methode in der Steuerung, die folgenden sein:

public function edit($id) 
    { 
     $contact = Contacts::findOrFail($id); 
     return view('contacts.edit', ['contacts' => $contact]); 
    }
