应该鼓励新手。相当令人沮丧
我是新手，在理解 php 文档时遇到问题。
有人可以提供确切的代码步骤以供我将来参考：
我想运行这个查询：
$query = $this->db->query("SELECT tracking_code FROM " . DB_PREFIX . "customer WHERE language_id = '" . (int)$this->customer->getId() . "'");
（我知道它只会返回一个值）和 1. 如果“如果存在跟踪命名 cookie，请将其删除或替换它并使用该查询返回的值设置一个名为“跟踪”的 cookie 一年。我该怎么做?
我对 php 知之甚少。但我觉得我在该 confirm.php 中没有提及 db 。它不扩展模型，我也不知道 $this 是否可以在这里工作，或者我正在处理的文件是。
