php - CodeIgniter 2.1.0 中的分页与模型中的查询

Question

对不起，主人......我是codeigniter的nubie（2个月）

我想问一下codeigniter 2.1.0中的分页，其中来自模型的查询结果

这是我的模型：

这是我的控制器

最后一个是我的 config.php

$config['limit_data'] = '10';

需要你的建议大师:)

谢谢你的时间。

Answer 1

你需要两个函数。首先，计算用户拥有的文件总数，其次是明智地获得结果分页。您在这里做错的是您在一个查询中获取所有记录而没有限制。

按照my previous这个答案。
