Php Codeigniter分页（第1页发布后）

在我的数据库中有大约1000条记录。 搜索查询在我的搜索结果页面的第1页中显示分页结果，但当我转到第2页、第3页等时。。。它什么也没给我看。它给我一条信息说没有找到记录。 我是否遗漏了与相对URI有关的内容？还是别的什么

已更新

尝试使用更标准的方式设置分页

$config['base_url'] = base_url('search-college');   
    //assuming example.com/search-college/[PAGE_NUMBER]

$config['total_rows'] = 200;
$config['uri_segment'] = 2;  
    //assuming example.com/search-college/[PAGE_NUMBER]

$config['num_links'] = 5;
$config['use_page_numbers'] = true;
$config['total_rows'] = $total_rows;
$config['per_page'] = 50;

$this->pagination->initialize($config);

---

原始答案

从上面发布的代码来看，似乎缺少一些逻辑来计算

ft\u search\u job2

过程的From\u限制和to\u限制

要使分页正常工作并使用过程（应尝试使用CodeIgniter查询生成器），请按如下方式计算偏移量：

from_limit = $page*$per_page

---

这是假设页面索引为0，而不是从1开始

如何计算from_限制和to_限制？您是否能够记录查询并查看实际查询的内容？记录查询时总是出现问题，您能为我指出正确的方向吗？如果我应该使用print\u r或last\u query？from\u limit和to\u limit只是过程中的INT值/长度“5”。echo$this->db->last\u query（）；出口在obj_结果查询给我这个“CALL ft_search_job2（“engineering”，0，50）”from_limit=$page*$per_page之后，这个应该被添加到控制器中，对吗？是的，应该是这样，然后在

调用中的from_limit参数中使用它

我尝试了同样的操作，但是页面不想在那之后加载，不确定我是否做对了：'你敢肯定你的程序设置正确吗？尝试使用CodeIgniter的查询构建器当我在模型中的param2中传递一个空变量，在该变量调用过程时，我可以在第一个页面中进行分页，但只要我单击分页的数字，它就会将我带到正确的结果集，然后分页就会消失。
