Question

我对所有这些都很新，所以如果不可能的话，请纠正我。

我正在尝试使用此SQL语句显示数据：

SELECT * FROM trail101 WHERE activities IN(\'Murals\',\'Concert\',\'Theater\',\'Museums\') ORDER BY id DESC LIMIT 0, 9

它只显示我拥有的前9个数据，但我希望能够导航到下一个9，其中单击分页会将SQL语句更新为ORDER BY id DESC LIMIT 9, 18以用于下一个页面等等。我该如何编写脚本呢？我有以下导航代码：

<div class="w3-center w3-padding-32">
<div class="w3-bar">
  <a href="#" class="w3-bar-item w3-button w3-hover-black" class="w3-bar-item w3-button w3-hover-black">«</a>
  <a href="#" class="w3-bar-item w3-black w3-button">1</a>
  <a href="#" class="w3-bar-item w3-button w3-hover-black">2</a>
  <a href="#" class="w3-bar-item w3-button w3-hover-black">3</a>
  <a href="#" class="w3-bar-item w3-button w3-hover-black">4</a>
  <a href="#" class="w3-bar-item w3-button w3-hover-black">»</a>
</div>

使用您的分页查询获得一个简单的代码示例，请查看
