Всем привет, столкнулся со сложностью вывода кастомного поля на frontend opencart.
Получилось реализовать добавление поля в админке. Оно успешно заносится в таблицу oc_product в поле weight_table. Далее сделал все по аналогичной логике только для вывода этого поля.
catalog/model/catalog/product.php в методе getProduct добавил переменную в массив
public function getProduct($product_id) {
$query = $this->db->query("SELECT DISTINCT *, pd.name AS name, p.image, (SELECT md.name FROM " . DB_PREFIX . "manufacturer_description md WHERE md.manufacturer_id = p.manufacturer_id AND md.language_id = '" . (int)$this->config->get('config_language_id') . "') AS manufacturer, (SELECT price FROM " . DB_PREFIX . "product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '" . (int)$this->config->get('config_customer_group_id') . "' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, (SELECT price FROM " . DB_PREFIX . "product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '" . (int)$this->config->get('config_customer_group_id') . "' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special, (SELECT points FROM " . DB_PREFIX . "product_reward pr WHERE pr.product_id = p.product_id AND customer_group_id = '" . (int)$this->config->get('config_customer_group_id') . "') AS reward, (SELECT ss.name FROM " . DB_PREFIX . "stock_status ss WHERE ss.stock_status_id = p.stock_status_id AND ss.language_id = '" . (int)$this->config->get('config_language_id') . "') AS stock_status, (SELECT wcd.unit FROM " . DB_PREFIX . "weight_class_description wcd WHERE p.weight_class_id = wcd.weight_class_id AND wcd.language_id = '" . (int)$this->config->get('config_language_id') . "') AS weight_class, (SELECT lcd.unit FROM " . DB_PREFIX . "length_class_description lcd WHERE p.length_class_id = lcd.length_class_id AND lcd.language_id = '" . (int)$this->config->get('config_language_id') . "') AS length_class, (SELECT AVG(rating) AS total FROM " . DB_PREFIX . "review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating, (SELECT COUNT(*) AS total FROM " . DB_PREFIX . "review r2 WHERE r2.product_id = p.product_id AND r2.status = '1' GROUP BY r2.product_id) AS reviews, p.sort_order FROM " . DB_PREFIX . "product p LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) LEFT JOIN " . DB_PREFIX . "product_to_store p2s ON (p.product_id = p2s.product_id) LEFT JOIN " . DB_PREFIX . "manufacturer m ON (p.manufacturer_id = m.manufacturer_id) WHERE p.product_id = '" . (int)$product_id . "' AND pd.language_id = '" . (int)$this->config->get('config_language_id') . "' AND p.status = '1' AND p.date_available <= NOW() AND p2s.store_id = '" . (int)$this->config->get('config_store_id') . "'");
if ($query->num_rows) {
return array(
'product_id' => $query->row['product_id'],
'name' => $query->row['name'],
'description' => $query->row['description'],
'meta_title' => $query->row['meta_title'],
'meta_h1' => $query->row['meta_h1'],
'meta_description' => $query->row['meta_description'],
'meta_keyword' => $query->row['meta_keyword'],
'tag' => $query->row['tag'],
'model' => $query->row['model'],
'sku' => $query->row['sku'],
'upc' => $query->row['upc'],
'ean' => $query->row['ean'],
'jan' => $query->row['jan'],
'isbn' => $query->row['isbn'],
'mpn' => $query->row['mpn'],
'location' => $query->row['location'],
'quantity' => $query->row['quantity'],
'stock_status' => $query->row['stock_status'],
'image' => $query->row['image'],
'manufacturer_id' => $query->row['manufacturer_id'],
'manufacturer' => $query->row['manufacturer'],
'price' => ($query->row['discount'] ? $query->row['discount'] : $query->row['price']),
'special' => $query->row['special'],
'reward' => $query->row['reward'],
'points' => $query->row['points'],
'tax_class_id' => $query->row['tax_class_id'],
'date_available' => $query->row['date_available'],
'weight' => $query->row['weight'],
'weight_class_id' => $query->row['weight_class_id'],
'length' => $query->row['length'],
'width' => $query->row['width'],

'length_class_id' => $query->row['length_class_id'],

'date_modified' => $query->row['date_modified'],
'viewed' => $query->row['viewed']
);
} else {
return false;
}
}
Затем в catalog/controller/product/product.php я эту переменную добавляю в массив $data[]
$data['model'] = $product_info['model'];
$data['reward'] = $product_info['reward'];
$data['points'] = $product_info['points'];
$data['weight_table'] = $product_info['weight_table'];
$data['description'] = html_entity_decode($product_info['description'], ENT_QUOTES, 'UTF-8');
Ну и пытаюсь вывести ее во view template/product/product.tpl
<div class="tab-pane active" id="tab-description" itemprop="description">
<div class="col-md-8"><?php echo $description; ?></div>
<div class="col-md-4"><?php echo $weight_table; ?></div>
</div>
Заранее спасибо за помощь.
