Question

我曾经为OpenCart 1.5制作了几个扩展程序，我希望＆＃34;转换＆＃34;他们加入OpenCart 2.3.0.2。

我很难确定如何为2.3.0.2执行以下操作：

    echo "Free Items Disabler started.<br>";
    $sqll = "SELECT * FROM " . DB_PREFIX . "product p LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) WHERE pd.language_id = '" . (int)$this->config->get('config_language_id') . "'";

    $result = mysql_query($sqll)or die(mysql_error());
    $antall = mysql_num_rows($result);
    echo "Products to check: ".$antall."<br>";
 ... 
$this->session->data['success'] = 'Free Items Disabler has
 disabled ' . $products_changed . ' products with no price!';

如何在页面上打印消息？ Echo没有在任何地方展示。
如何计算查询结果？我尝试时页面总是停止工作。

我已经尝试过查看其他2.3扩展程序来解决这个问题，但我找不到任何类似的东西。我花了两天时间试图解决这个问题。

解决方案原来是：

$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "product p LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) ");
$num = $query->rows;
...
$this->session->data['success'] = 'Free Items Disabler has disabled ' . $products_changed . ' products with no price!';

如何将（重新编码）扩展从OpenCart 1.5转换为2.3
