How to get user images by tag?

Question

Laravel

Hello, tell me please. I have an image model and it has a method

public function tags(): BelongsToMany
{
   return $this->belongsToMany(Tag::class);
}

An image can have many tags, a tag can have many images.
And now I don’t understand a little how I can make a request, I need to display images for the selected tag.
I did this first, but it doesn't work as expected.
In $request->tags - array of id of selected tags

$images = $user->images()->with(['tags' => function($query) use ($request) {
  if($request->has('tags')) {
    $query->whereIn('tags.id', $request->tags);
  }
}])->orderBy('id', 'desc')->paginate(15);

And this is how it works:

if($request->has('tags')) {
  $images = $user->images()->whereHas('tags', function (Builder $query) use ($request) {
    $query->whereIn('tags.id', $request->tags);
  })->orderBy('id', 'desc')->paginate(15);
}
else {
  $images = $user->images()->orderBy('id', 'desc')->paginate(15);
}

But I'm thinking maybe it's possible to do something differently, tell me please, thank you in advance for the answer.

Answer 1

$images = $user->images()
  ->when($request->has('tags'), function($q) use ($request) { 
      $q->whereHas('tags', function ($q) use ($request) {
         $q->whereIn('tags.id', $request->tags);
      })
  })
  ->orderBy('id', 'desc')->paginate(15);

Try this
