Access query "wheres"

Title is vague, exuse me for that.

Is there a way to get the current id you're looping through? As you can see in the example below, I need the post id from a couple callbacks before. Anyone knows if this is possible?

$collections = Collection::with(['posts' => function ($q) {
      // i need current id from post where the query is looping through
      $id = $q;
      $q->with(['type' => function ($q) use ($id) {
        $q->with(['content' => function ($q) use ($id) {
          // to use here
          $q->where('post_id', $id);
        }]);
      }]);
    }]);    

I can find the id at hasMany->query->wheres, is there anyway I can get to there?
