Почему получаю ошибку Fatal error: Uncaught Error: Call to a member function getTotalReviews() on null?

[martovytskyi87]

Есть модуль с отзывами. Пыиюсь в админке вывести уведомление о новом отзыве admin/controller/catalog/p_review.php: 

$p_review_total = $this->model_catalog_p_review->getTotalReviews();
$data['p_reviewtotal'] = $p_review_total;

$results = $this->model_catalog_p_review->getReviews($filter_data);

header.php

// Reviews
$this->load->model('catalog/p_review');

$p_reviewtotal = $this->model_catalog_p_review->getTotalReviews(array('status' => 0));

$data['p_reviewtotal'] = $p_reviewtotal;

$data['p_review'] = $this->url->link('catalog/p_review', 'user_token=' . $this->session->data['user_token'] . '&status=0', true);

header.twig

 

    {% if p_review_total >= 1 %}
      <li class="dropdown"><a href="{{ p_review }}"> <i class="fa fa fa-comments-o fa-lg blinking" style="color:green"></i> <span style="font-size: 10px">{{ text_review }}</span> <sub>{{ text_new_review }}: ({{ review_total }})</sub></a></li>
   {% endif %}

 

Получаю ошибку

Fatal error: Uncaught Error: Call to a member function getTotalReviews() on null

Решил проблему ик: 
header.php

$this->load->model('catalog/p_review');

$p_review_total = $this->model_sale_order->getTotalReviews('');
$data['p_review_total'] = $p_review_total;

$data['review'] = $this->url->link('catalog/p_review', 'user_token=' . $this->session->data['user_token'] . '&status=0', true);

model/p_review.php

public function getTotalReviews($status) {
    $query = $this->db->query("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "p_review WHERE status = '" . $status . "'");
    return $query->row['total'];
}
