Recursive display of data with blade, laravel - laravel

Question

My Controller:
class Comments extends Controller {
public function GenerateComments($id){
$theme = DB::table('New_Themes')
->where('id', $id)
->get();
$Comments = NewTheme_Comment::where('id_theme', $id)->get();
return view('comments', ['Themes'=>$theme, 'Comments'=>$Comments]);
}
My Table(NewTheme_Comment):
id
parent_id
id_theme
user
text
upVotes
downVotes
My view(contains the recursive display of the tree of comments like the same in reddit), ......(data) contains the bootstrap media object, and the </div>'s things are used to round up (visually) the tree of comments as it should be:
<?php
tree($Comments, 0, 0);
$var = -1;
function tree($Comments, $parent_id = 0, $level=0, $c=0) {
global $var;
foreach($Comments as $Comment) {
if($Comment['parent_id'] == $parent_id) {
If ($level > $var) $var++; else {
for ($i = $var-$level+1; $i>0; $i--) { if ($c < 0) echo '</div> </div>'; else $c--; };
$var=$level;
};
echo '........(data)';
tree($Comments, $Comment['id'], $level+1,$c);
};
};
};
?>
The problem is that .........(data) should contain this stuff:
<div class="media">
<div class="media-left">
<img class="media-object" style="height:40px; width:40px;" src="{{ URL::asset("images/upVote.svg") }}" >
<div>{{$Comment->upVotes-$Comment->downVotes}}</div>
<img class="media-object" style="height:40px; width:40px;" src="{{ URL::asset("images/downVote.svg") }}" >
</div>
<div class="media-body">
<p class="media-heading">{{ $Comment->text }}</p>
<p class="media-heading">{{ $Comment->user }} / {{ $Comment->created_at }} </p>
And I am using the blade above this line | , which I can't integrate into that echo in view, replacing the ..........(data).
I have the intuition that the function I should integrate into the controller but I am broken(I spent to much time on recursive method of displaying comments) and I don't know how to take the data and print out it as whole unit recursively.
Any help is GREATLY appreciated to find a way out of this mess, thank you very much
Edit 1:
This is an example if i am filling with bootstrap media object in ........(data):
<div class="media">
<a class="media-left" href="#">
<img class="media-object" src="..." alt="...">
</a>
<div class="media-body">
<h4 class="media-heading">Media heading</h4>
Without 2 x </div>

Answer 1

You are approaching the views in a wrong way, as blade templates are not meant to use functions, it's better to follow the below recommendations.
The best way for that is to place the function code inside a blade file, for example recursive.blade.php:
recursive.blade.php
#foreach($comments as $comment)
//place your code here
#endforeach
Then in your main blade you can call it several times:
main.blade.php
<div>
#include('recursive', ['comments' => $comments])
</div>

Answer 2

The below example works for me and is the most widely used approach. remember the default value for parent_id is -1.
Model
public function children(){
return $this->hasMany(self::class,'parent_id','id')->with('children');
}
Controller
$comments = Comments::where('parent_id','=',-1)->get();
return view('comments',['comments'=> $comments]);
Blade (comments.blade.php)
<div class="tree">
#include('comment-list-widget',['comments' => $comment])
</div>
Blade (comment-list-widget.blade.php)
<ul>
#foreach($comments as $comment)
<li>
<a>{{$comment->text}}</a>
#if(!empty($comment->children) && $comment->children->count())
#include('comment-list-widget',['comments' => $comment->children])
#endif
</li>
#endforeach
</ul>
