Laravel 8: How to add pagination after retrieving data from ManyToMany Relationship

Question

I'm working on a forum project using Laravel 8, and in this project, I have made a page for getting all the questions with specific tag. Here is the the method to do that:

public function tag($name)
    {
        $tag = \App\Models\Tag::findOrFail($name);
        return view('tag',[
            'single' => $tag
        ]);
    }

And then inside tag.blade.php :

@foreach($single->questions as $one)
  ...
@endforeach

But now I need to add pagination for this page, so if questions are more than a custom number, they can navigate to other pages.

In fact I had already added pagination to my other page which shows all the entire questions:

public function allQuestions()
    {
        $all = Question::latest()->paginate(20);

        return view('questions.allquestions',[
            'all' => $all
        ]);
    }

But I don't know really how to add this feature to tag() method.

So if you know how to add this pagination, please let me know...

I would really appreciate any idea or suggestion from you guys.

Thanks in advance.

Theres 2 choices for this:

First Choice:

public function tag($name)
    {
        $tag = \App\Models\Tag::findOrFail($name);
        $questions = $tag->question()->paginate(10);
        return view('tag',[
            'single' => $tag, 'questions' => $questions
        ]);
    }

Then, on your view, you can just loop through the questions.

@foreach ($questions as $question)
    ... fill this
@endforeach

{!! $questions->render() !!}

Second Choice:

public function tag($name)
    {
        $tag = \App\Models\Tag::findOrFail($name);
        $tag->setRelation('questions',$tag->questions()->paginate(10));
        return view('tag',[
            'single' => $tag
        ]);
    }

Then, on your view, you can just loop through the questions.

@foreach ($single->questions as $question)
    ... fill this
@endforeach
