Get different data with same ID in CodeIgniter with a single Query

Let's say that I have a system of categories, tags and images where when creating a post, it is sent to my table of relations:

id, post_id, term_id, file_id, status, type.

Obviously when there is a value in the term_id, the type is basically a category or tag and the same with the file_id whose type is "media"; the status field is always 'attached'

I would just like to know if instead of doing this (example of the model I use to get the files_id type "media"):

public function getPostGallery($id){
        $this->db->select('*');
        $this->db->from($this->relationship);
        $this->db->where('type', 'media');
        $this->db->where('status', 'attached');
        $this->db->where('post_id', $id);

        $query = $this->db->get();

        if($query->num_rows() >= 0){
            return $query->result();
        } else {
            return false;
        }
    }

and this in the view:

<?php if($gallery): ?>
        Has un foreach de type media
    <?php endif; ?>

It was possible to do something like the following:

public function getPostGallery($id){
        $this->db->select('*');
        $this->db->from($this->relationship);
        //$this->db->where('type', 'media');
        $this->db->where('status', 'attached');
        $this->db->where('post_id', $id);

        $query = $this->db->get();

        if($query->num_rows() >= 0){
            return $query->result();
        } else {
            return false;
        }
    }

<?php if($gallery->type == 'media'): ?>
        Has un foreach de type media
    <?php endif; ?>
    <?php if($gallery->type == 'tag') : ?>
        Has un foreach de type tag
    <?php endif; ?>

I do not know if I explain but thank you in advance.
