我在我的网站上有这个分页。我的问题是下面的链接超出了太多。例如，它转到第228页，那里就没有数据了。
这是我的控制器代码
public function index(){
$this->data['title'] = 'Programs | Spring Rain Global Consultancy Inc';
$this->data['active_menu'] = 'programs';
$this->data['active_link'] = 'program_menu';
$config = array();
$config['base_url'] = base_url(). "programs/index";
$config['total_rows'] = $this->am->record_count();
$config['per_page'] = 12;
$config['uri_segment'] = 3;
$choice = $config['total_rows'] / $config['per_page'];
$total_rows = $config['total_rows'] = $this->am->record_count();
$config['num_links'] = round($choice);
$this->pagination->initialize($config);
$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$this->data['fecth_activities'] = $this->am->getAllActivities($config['per_page'], $page);
$this->data['links'] = $this->pagination->create_links();
//echo "<pre>";
//print_r($this->data['links']);
//echo "</pre>";
$this->load->view('pages/header', $this->data);
$this->load->view('templates/programs', $this->data);
$this->load->view('pages/footer');
$this->load->view('pages/footer_below');
}
以下是我的模型
class Activities_model extends CI_Model{
public function record_count(){
return $this->db->count_all('seminars');
}
public function getAllActivities($start, $limit){
return $this->db->limit($start, $limit)
->select('seminars.id,
seminars.category,
seminars.thumb,
seminars_category.id,
seminars_category.category,
seminars_category.url,
seminars_category.date,
seminars_category.abvr'
)
->from('seminars')
->join('seminars_category', 'seminars_category.id = seminars.category')
->where('seminars.id =', 1)
->or_where('seminars.id =', 7)
->or_where('seminars.id =', 12)
->or_where('seminars.id =', 20)
->or_where('seminars.id =', 24)
->or_where('seminars.id =', 29)
->or_where('seminars.id =', 77)
->or_where('seminars.id =', 84)
->or_where('seminars.id =', 103)
->or_where('seminars.id =', 157)
->or_where('seminars.id =', 187)
->or_where('seminars.id =', 234)
->or_where('seminars.id =', 241)
->or_where('seminars.id =', 308)
->or_where('seminars.id =', 314)
->or_where('seminars.id =', 390)
->or_where('seminars.id =', 407)
->or_where('seminars.id =', 414)
->or_where('seminars.id =', 429)
->or_where('seminars.id =', 455)
->or_where('seminars.id =', 462)
->or_where('seminars.id =', 511)
->or_where('seminars.id =', 537)
->or_where('seminars.id =', 573)
->or_where('seminars.id =', 591)
->or_where('seminars.id =', 641)
->order_by('seminars_category.date', 'DESC')
->get()->result_object();
$query = $this->db->get('seminars');
if($query->num_rows > 0){
foreach($query->result() as $row){
$data[] = $row;
}
return $data;
}
return false;
}
}
这件事有效但只有下面的链接超过228。

试试这个，
class Activities_model extends CI_Model {
public function record_count() {
$this->db->where('seminars.id =', 1)
->or_where('seminars.id =', 7)
->or_where('seminars.id =', 12)
->or_where('seminars.id =', 20)
->or_where('seminars.id =', 24)
->or_where('seminars.id =', 29)
->or_where('seminars.id =', 77)
->or_where('seminars.id =', 84)

你正在计算数据库中的所有元素......把条件放在 record_count 函数上，它可以解决你的问题
