CI框架分页类

分页类
1.分页类参数说明
'base_url' => 指向你的分页所在的控制器类/方法的完整的 URL,
'total_rows' => 数据的总行数,
'per_page' => 每页显示的项目,
'uri_segment' => 自动检测哪一段包含页数,
'num_links' => 放在当前页前后显示的链接数,

2.分页类使用
$this->load->library('pagination');//加载分页类
$this->load->helpers('config_pagination');//使用配置项参数
$cfg = config_pagination($url, $count, $per_page, 4);//base_url , total_rows , per_page ,uri_segment
$this->pagination->initialize($cfg);//初始化分页类
$this->pagination->create_links();//在视图中显示

3.分页类技巧
使用参数表示 列表 和 单条 两个不同类型，
查询对应的总数，uri_segment使用同一个分页类

4.完整的分页类代码
public function lists($type = '', $start = 0)
{

$s = trim($this->input->get('s'));
$data['s'] = $s;
$per_page = 20;
if ($type == 'search') {
$content = $this->suits_model->getRowsBytype($s, $start, $per_page);
$count = $content['count'];
$url = "/admin/suits/lists/$type";
} else {
$start = $type;
$content = $this->suits_model->getRowsByALL($start, $per_page);
$count = $content['count'];
$url = "/admin/suits/lists/";
}
$options = $this->suitstypes_model->getRows();
//分页
$this->load->library('pagination');
$this->load->helpers('config_pagination');
$cfg = config_pagination($url, $count, $per_page, 4);
$this->pagination->initialize($cfg);
$data['state_button'] =$this->state_button;
$data['pages_html'] = $this->pagination->create_links();
$data['count'] = $count;
$data['content'] = $content['content'];
$data['title'] = '包装列表';
$data['user'] = $this->user;
$data['options'] = $options['query']->result_array();
$data['base_url'] = $this->base_url;
$this->load->view('admin/header', $data);
$this->load->view('admin/suits_lists');
$this->load->view('admin/footer');
}
