Question

我是codeigniter的新手，我正在处理它的分页功能。但我面临一个问题，它在所有页面上显示相同的值。这是我的代码

控制器

$this->load->library('pagination');
        $config['base_url'] = base_url().'index.php/dashboard/productcolor/'.$id;
        $config["total_rows"] = $this->mdashboard->getAllcolorIDCount($id);
        $config["full_tag_open"] = "<ul class='pagination'>";
        $config["full_tag_close"] = "</ul>";
        $config["num_tag_open"] = "<li>";
        $config["num_tag_close"] = "</li>";
        $config["cur_tag_open"] = "<li class='active'>";
        $config["cur_tag_close"] = "</li>";
        $config["prev_tag_open"] = "<li class='prev'>";
        $config["prev_tag_close"] = "</li>";
        $config["next_tag_open"] = "<li class='next'>";
        $config["next_tag_close"] = "</li>";
        $config["first_link"] = "<li>&lsaquo; First";
        $config["first_link"] = "</li>";
        $config["last_link"] = "<li>Last &rsaquo;";
        $config["last_link"] = "</li>";
        $config['per_page'] = 2;
        $config['uri_segment'] = 4;
        $this->pagination->initialize($config);
        $data["totalpage"]=$config['per_page'];
        $data['colorproduct'] = $this->mdashboard->GetAllcolorByPage($id,$config["per_page"], $page);

查看

<? echo $this->pagination->create_links();?></div>

模型

$data = array();
    $Q = $this->db->select('*,(select pname from tbl_product where id=tbl_productcolor.pid)as productname,(select image from tbl_product where id=tbl_productcolor.pid)as image FROM tbl_productcolor where cid="'.$id.'" order by id asc ');
    $Q =  $this->db->get();

    if ($Q->num_rows() > 0)
    {
        foreach ($Q->result_array() as $row)
        {
            $data[] = $row;
        }
    }
    $Q->free_result();  
    return $data;

您需要为查询添加限制像这样在你的模型中

function GetAllcolorByPage($id,$limit,$offset) {
    $data = array();
        $Q = $this->db->select('*,(select pname from tbl_product where id=tbl_productcolor.pid)as productname,(select image from tbl_product where id=tbl_productcolor.pid)as image FROM tbl_productcolor where cid="'.$id.'" LIMIT'. $offset.' , '. $limit .' order by id asc ');
        $Q =  $this->db->get();
    if ($Q->num_rows() > 0)
    {
        foreach ($Q->result_array() as $row)
        {
            $data[] = $row;
        }
    }
    $Q->free_result();  
    return $data; 

}

将配置更改为 $config['use_page_numbers'] = FALSE;
