How to implement PHP CodeIgniter paging and multi-condition query
This article mainly introduces PHP CodeIgniter paging examples and detailed explanations of multi-condition query ideas. It is very good and has reference value. Friends in need can refer to it
When using the CI framework recently, use I have installed the paging class of CI. I used to use the front-end paging class. This time I simply used the one that comes with the framework. I might as well record it in my forgetful mind.
Because there is a conditional filtering form on the page, the desired effect is that after entering the conditions, the entered conditions can be maintained after the page jump. After thinking about it for a while, I came up with the following code.
controller code
class Monitors extends CI_Controller {
public function warning(){
$config= array();
$config['per_page'] = 15; //每页显示的数据数
$current_page = intval($this->input->get("per_page")); //获取当前分页页码数
$status=$this->input->get("filter-status",TRUE);
$level=$this->input->get('filter-level',TRUE);
$timestamp=$this->input->get('filter-timestamp',TRUE);
$all = $this->monitors_m->getAllData($current_page,$config['per_page'],$status,$timestamp,$level);
//这里返回的有总条数和具体的数据，根据自己的情况略加修改即可
$data['allevent'] = $all['content'];
$config['total_rows'] = $all['count'];//总条数
$config['num_links'] = 3;//页码连接数
$config['use_page_numbers'] = TRUE;
$config['page_query_strings'] = TRUE;//关键配置
$config['base_url'] = base_url().'index.php/monitors/warning?'&filter-status='.$status.'&filter-level='.$level.'&filter-timestamp='.$timestamp;//关键配置
$this->load->library('pagination');//加载ci pagination类
$this->pagination->initialize($config);
$data['page'] = $this->pagination->create_links();//关键代码
$this->load->view("monitors_v",$data);
}Key configuration parameters
$config[‘page_query_string']
If If set to true, the url will be "index.php/monitors/warning?per_page=20" like this
[Note] "per_page" is the query string passed by default, but you can also use $config[ 'query_string_segment'] = 'your string' to configure
In my solution, it is set to TRUE. Of course, TRUE is the default value, and you can leave it alone;
$config[‘base_url']
When it is initially set to the following situation, it is possible to perform conditional filtering on a certain page, but after the jump, the conditions are no longer due to refresh problems.
$config['base_url'] = base_url().'index.php/monitors/warning;
Use the following method, roar hoho
$status=$this->input->get("filter-status",TRUE);
$level=$this->input->get('filter-level',TRUE);
$timestamp=$this->input->get('filter-timestamp',TRUE);
$config['base_url'] = base_url().'index.php/monitors/warning?'&filter-status='.$status.'&filter-level='.$level.'&filter-timestamp='.$timestamp;//关键配置view page The code
is just one sentence. Just add this sentence where you need to place the paging element. The $page variable here is stored in the controller. $this->pagination->create_links ();
<?php echo $page?>
Set paging style
The bootstrap style is used here
$config['first_link'] = "<<";//首页 $config['prev_link'] = "<";//上一页 $config['next_link'] = ">";//下一页 $config['last_link'] = ">>";//尾页 $config['full_tag_open'] = '<ul class="pagination pagination-split">'; $config['full_tag_close'] = '</ul>'; $config['first_tag_open'] = '<li>';//第一个链接的起始标签。 $config['first_tag_close'] = '</li>';//第一个链接的结束标签。 $config['next_tag_open'] = '<li>';//下一页链接的起始标签。 $config['next_tag_close'] = '</li>';//下一页链接的结束标签。 $config['prev_tag_open'] = '<li>';//上一页链接的起始标签。 $config['prev_tag_close'] = '</li>';//上一页链接的结束标签。 $config['cur_tag_open'] = '<li class="active"><a>'; $config['cur_tag_close'] = '</a></li>';//当前页链接的结束标签。 $config['num_tag_open'] = '<li>';//数字链接的起始标签。 $config['num_tag_close'] = '</li>';//数字链接的结束标签。
