[Solved] MY Custom Fourm Vote: Stop forum votes going below 0

On my forum I am learning to make I have made a reputation vote model.

I would like to know. When forum_user_reputation get's to 0 from been voted down $this->input->post('vote_down') to it then it should stop there.

Currently if the question gets down voted still the forum_user_reputation will go into negative -2 but I need to make it stop at 0

How could I make suitable changes to my function update_forum_question()

PHP Code:

public function update_forum_question() {
        $current_votes = $this->get_question_reputation();

        if ($this->input->post('vote_up') == TRUE) {

            $sum_total = $current_votes + $this->input->post('vote_up');
            
            $data = array(
                'forum_question_reputation' => $sum_total    
            );

            $this->db->where('forum_question_id', '1');
            $this->db->where('forum_user_id', '1');
            $this->db->update('forum_questions', $data);

            $forum_user_reputation = $this->get_forum_user_reputation();

            $forum_reputation = $forum_user_reputation  + 5;

            $data = array(
                'forum_reputation' => $forum_reputation    
            );

            $this->db->where('forum_user_id', '1');
            $this->db->update('forum_user', $data);

        } elseif ($this->input->post('vote_down') == TRUE) {

            $sum_total = $current_votes - $this->input->post('vote_down');

            $data = array(
                'forum_question_reputation' => $sum_total
            );

            $this->db->where('forum_user_id', '1');
            $this->db->where('forum_question_id', '1');
            $this->db->update('forum_questions', $data);

            $form_votes = $current_votes - 2;

            $data = array(
                'forum_reputation' => (int)$form_votes    
            );

            $this->db->where('forum_user_id', '1');
            $this->db->update('forum_user', $data);

        }
    } 


Thanks for you advice
