Output looks like

Get Previous Record

$previous_record = Post::where('id', '<', $post->id)->orderBy('id','desc')->first();

Get Next Record

$next_record = Post::where('id', '>', $post->id)->orderBy('id')->first();

Update Controller

app\Http\Controllers\PostController.php

public function show($id)
    {
        $post = Post::findOrFail($id);

        $previous_record = Post::where('id', '<', $post->id)->orderBy('id','desc')->first();
        $next_record = Post::where('id', '>', $post->id)->orderBy('id')->first();


        return view('single_post',compact('post','previous_record','next_record'));
    }

The above code is responsible for fetching a single record from the posts table using id. and also we can find the previous and next records just by writing two lines of code. we send back every record to the single_post.blade.php file.

Update View file

app\resources\views\single_post.blade.php

 <div class="container mt-5">
        <div class="row">
            <div class="col-md-12">
                <div class="card">
                    <div class="card-header">
                        <h4>{{$post->title}}</h4>
                    </div>
                    <div class="card-body">
                        <blockquote class="blockquote mb-0">
                            {{$post->body}}
                        </blockquote>
                    </div>
                </div>
            </div>
        </div>
        <div class="row">
            <div class="col-md-6">
            @if (isset($previous_record))
                <div class="alert alert-success">
                    <a href="{{ route('posts.show',$previous_record->id) }}">
                        <div class="btn-content">
                            <div class="btn-content-title"><i class="fa fa-arrow-left"></i> Previous Post</div>
                        </div>
                    </a>
                </div>
            @endif
            </div>
        <div class="col-md-6">
            @if (isset($next_record))
                <div class="alert alert-success">
                    <a href="{{ route('posts.show',$next_record->id) }}">
                        <div class="btn-content">
                            <div class="btn-content-title">Next Post <i class="fa fa-arrow-right"></i></div>
                        </div>
                    </a>
                </div>
            @endif
        </div>
    </div>

Add routes

app\routes\web.php

Route::resource('/posts',PostController::class);

notice that we use resource routes for our PostController. If you have not then you can create manually.

Output

http://127.0.0.1:8000/posts/

http://127.0.0.1:8000/posts/2

Hope, it will helps!
