CodeIgniter中的分页问题

Question

我在系统中遇到了分页问题。分页在这里运作良好。

但是，如果我在该文本字段中搜索某些内容，并且结果超过5（$config['per_page'] = 5;），则表示不显示分页按钮。

实际上，搜索关键字' shihas '的结果为6。

一旦我去www.example.com/path/2，我也能看到第六个结果。

但是，分页链接不存在。请告诉我这个问题的解决方案。

您可以使用实时的数据表。

DataTables是jQuery Javascript库的插件。它是一个高度灵活的工具，基于渐进增强的基础，并将为任何HTML表添加高级交互控件。

分页，即时搜索和多列排序几乎支持任何数据源：DOM，Javascript，Ajax和服务器端处理易于主题化：DataTables，jQuery UI，Bootstrap，FoundationWide各种扩展程序。编辑器，按钮，FixedColumns和更多广泛的选项和一个美丽的，  富有表现力的APIFully internationalisableProfessional质量：由2900+单元测试套件支持免费开源软件（MIT许可证）！提供商业支持。

只需输入代码：

$(document).ready(function(){  
   $('#myTable').DataTable();
});
