What would be Url for nested resource route?

I am able to display all comments of a post using the below code

public function index($post_id)
{

    $comments = post::find($post_id)->comments;        
    return view ('comment.index', compact ('posts','comments'));
}

and in view index.blade.php

<p> This is comment title {{ $comment->title }}</p>
<p> This is comment name {{ $comment->name }}</p>

but cannot go to the url of each comments ie. show.blade.php gets error with below code when add a "href="

<a href="{{ url('posts/' . $post->id . '/comment '/' . $comment->id . ')}}" >{{ $comment->name }}</a> 
<p> This is comment title {{ $comment->title }}</p>
 <p> This is comment name {{ $comment->name }}</p>

what will be the url to visit and show posts/1/comments/1 currently I am getting error undefined $post .

You aren't sending a variable named post to the blade. And looking at the follow piece of code

return view ('comment.index', compact ('posts','comments'));

posts also looks undefined.

You need to send the post to the view instead of just the comments.

In the controller change:

$comments = post::find($post_id)->comments;        
return view ('comment.index', compact ('posts','comments'));

To

$post = post::find($post_id);        
return view ('comment.index', compact ('post'));

And then in your view change

<a href="{{ url('posts/' . $post->id . '/comment '/' . $comment->id . ')}}" >{{ $comment->name }}</a> 
<p> This is comment title {{ $comment->title }}</p>
<p> This is comment name {{ $comment->name }}</p>

To

{foreach $post->comments as $comment}
    <a href="{{ url('posts/' . $post->id . '/comment '/' . $comment->id . ')}}">{{ $comment->name }}</a> 
    <p> This is comment title {{ $comment->title }}</p>
    <p> This is comment name {{ $comment->name }}</p>
{/foreach}

I would also suggest using the route() function instead of url(). You can find more about that here

You're getting the error because you're not passing post ID to the view. Do this instead:

return view ('comment.index', compact ('post_id', 'comments'));

Then use the variable in the view, for example:

{{ url('posts/' . $post_id . '/comment '/' . $comments->first()->id . ')}}
