【问题描述】：
我正在尝试动态添加或连接多个 sql 查询。
我正在创建一个分页脚本，我正在尝试添加一些过滤按钮或链接，在这种情况下，当用户单击链接时，它会将 id 添加到 sql 查询中，然后显示结果。
为了更好地理解我的意思，我将向您展示我正在编写的脚本：
下面你会看到我有三个链接；市场营销、汽车和体育。这些链接代表过滤器选择，因此当单击“Marketing”之类的链接时，sql 查询将插入“category=$ids”的营销。这很好用，除非我想添加多个选择，例如仅选择“营销”和“体育”而不显示“汽车”。
有没有一种简单的方法可以向 sql 连接添加多个 id 而不是一个？
我希望这是有道理的，如果您需要任何进一步的解释，请告诉我。感谢您对此的任何帮助。
<?php
$ids=$_GET['id'];
echo $ids;
$pageN = $_GET['page'];
echo $pageN;
