Here I will show you how to display previous and next post link in single post page in laravel. For this we will use `max` and `min` functions in laravel. I'm using the following code to controller function to get next and previous post within a post.

public function post($id)
{
    $post = Post::find($id);
    $previous = Post::where('id', '<', $post->id)->max('id');
    $next = Post::where('id', '>', $post->id)->min('id');
    return view( 'post', compact( 'post', 'next', 'previous' ));
}

In Route file

Route::get('post/{id}','BlogController@post')->name('post.show');

In view

@if($next)
   <a href="{{ route( 'blog.show', $next->id ) }}">{{$next->title}}</a>
@endif
@if($previous)
   <a href="{{ route( 'blog.show', $previous->id ) }}">{{$previous->title}}</a>
@endif

public function post($id)
{
    $post = Post::find($id);
    $previous = Post::where('id', '<', $post->id)->max('id');
    $next = Post::where('id', '>', $post->id)->min('id');
    return view( 'post', compact( 'post', 'next', 'previous' ));
}

Route::get('post/{id}','BlogController@post')->name('post.show');

@if($next)
   <a href="{{ route( 'blog.show', $next->id ) }}">{{$next->title}}</a>
@endif
@if($previous)
   <a href="{{ route( 'blog.show', $previous->id ) }}">{{$previous->title}}</a>
@endif
