Question

亲爱的，亲爱的，当用户需要删除或编辑帖子，laravel show error＆＃34;你不能编辑帖子......＆＃34;我在laravel和用户＆＃34; auth＆＃34;中使用模型和控制器。用于删除或编辑的访问帖子的系统ID现在看到我的工作：

索引视图

@extends('layouts.app')

@section('content')
@auth
    <h6 class="alert alert-dark">Dear Guest {{ Auth::user()->name }} for send a post <a class="btn btn-success" href="{{ route('ads.create') }}">Click</a> Here</h6>
@endauth

@guest
    <div class="alert alert-primary">for send a post you can <a class="btn btn-success" href="{{ route('register') }}">Register</a></div>
@endguest

@if(count($adses) > 0)
<div class="row">
    @foreach($adses as $ads)
        <div class="col-xl-3 col-lg-3 col-md-6 col-sm-12">
            <div class="card mb-4">
                <img class="card-img-top img-fluid" src="/storage/cover_images/{{$ads->cover_image}}" alt="Card image cap">
                <div class="card-body">
                    <h6 class="card-title"><a href="/ads/{{ $ads->id }}">{{ $ads->title }}</a></h6>
                    @if(!Auth::guest())
                        @if(Auth::user()->id == $ads->user_id)
                    <div class="row">
                        {!!Form::open(['action' => ['AdsController@destroy', $ads->id], 'method' => 'POST',]) !!}
                            {{Form::hidden('_method', 'DELETE')}}
                            {{Form::submit('Delete', ['class' => 'btn btn-danger'])}}
                        {!!Form::close() !!}
                        <a href="/ads/{{ $ads->id }}/edit" class="btn btn-primary mr-4">Edit</a>
                    </div>
                        @endif
                    @endif
                </div>
            </div>
        </div>
    @endforeach
    {{ $adses->links() }}
@else

广告模型

用户模型

<?php

广告控制器

}
}

击溃

Auth::routes();
Route::get('/home', 'HomeController@index')->name('home');
Route::resource('/', 'AdsController');
Route::resource('ads', 'AdsController');

现在，在发送帖子并登录系统用户后，无法删除或编辑她的帖子。

谢谢

Answer 1

auth()->user()->id !== $ads->user_id .

Уou有这条线。如果用户在创建帖子时没有登录，那么您将拥有user_id == null。签入DB而不是user_id？

Answer 2

我解决了我的问题

 if(auth()->user()->id !== $ads->user_id)

由于您正在使用！==，请确保您的user_id为整数

无法编辑或删除laravel项目中的帖子
