在使用我的API时遇到一些问题。这是我当前的代码，它不起作用（根本没有显示任何分页）：

对此的任何帮助将不胜感激。
我已经尝试了多种变体，谷歌搜索了一下，但其中大部分与MySQL有关。
我正在使用API来获取数据而不是数据库，“page”和“total_pages”是JSON响应的一部分，所以我有点不确定如何解决这个问题。
干杯，

12/4/2012答案的第二个版本。
有一个网站，您可以看到分页和显示代码正常工作：
它允许您：
1) Change the number of items per page
2) Change the number of 'slots' in the page selector.
我已完成'分页代码'。
您现在可以调整“页面选择器”代码中显示的“插槽”数量。
我对目前的“分页”代码感到满意。
“宠物”显示代码已转换为使用“Savant3”模板，该模板使用PHP作为“模板”语言。有用的部分是它可以轻松地将“显示”与“逻辑”代码分开。虽然仍然允许“视图”中提供PHP的所有功能。我更喜欢这个。

我将为“分页”代码制作一个单独的存档，因为它实际上是“独立”代码。可以在任何地方使用。
分页代码由'常量'和提供的参数控制。格式化都是css。
当前网站使用您之前提供的“测试数据”。
任何人都可以免费使用“分页代码”。这是在任何地方重新发明的标准东西。包括我在内。它构造时使用类和“页面”数组，每个页面具有固定数量的项目。您可以设置“当前页码”，它将返回以下内容：
1）要在页面上显示的项目数组
2）“页面选择器”，其中包含用HTML修饰的可变数量的“插槽”。
