如何使用类别发布 Codeigniter 进行分页

Question

任何人都知道如何解决我的问题.. 我的问题是基于类别工作的分页但是当我单击按钮分页时结果是找不到页面可能我的路线有问题但我不确定..请帮助我.. 这是我的路线

$route['blog/category/:any']                 = 'Blog_Category_Post/page';

这是我的控制器

public function page($offset=0)
{
    $id=$this->uri->segment('3');
    $this->db->select('id,categoryId');
    $this->db->from('t_blog_post');
    $this->db->where('categoryId',$id);
    $query= $this->db->get();

    //$jml                        = $this->db->get('t_blog_post');
    $config['base_url']         = base_url().'blog/category/'.$id.'/page';
    $config['total_rows']       = $query->num_rows();
    $config['per_page']         = 2; /*Jumlah data yang dipanggil perhalaman*/  
    $config['uri_segment']      = 4;    /*data selanjutnya di parse diurisegmen 3*/
    /*Class bootstrap pagination yang digunakan*/
    $config['full_tag_open']    = "<ul class='pagination pagination-sm' style='position:relative; top:-25px;'>";
    $config['full_tag_close']   ="</ul>";
    $config['num_tag_open']     = '<li>';
    $config['num_tag_close']    = '</li>';
    $config['cur_tag_open']     = "<li class='disabled'><li class='active'><a href='#'>";
    $config['cur_tag_close']    = "<span class='sr-only'></span></a></li>";
    $config['next_tag_open']    = "<li>";
    $config['next_tagl_close']  = "</li>";
    $config['prev_tag_open']    = "<li>";
    $config['prev_tagl_close']  = "</li>";
    $config['first_tag_open']   = "<li>";
    $config['first_tagl_close'] = "</li>";
    $config['last_tag_open']    = "<li>";
    $config['last_tagl_close']  = "</li>";
    $this->pagination->initialize($config);

    $list_blogPost=$this->BlogCategory->get_post($config['per_page'], $offset,$id);
    $list_lastblogPost=$this->BlogCategory->get_last_post();
    $list_blogCategory=$this->BlogCategory->get_category();
    $data=array(
        'title'          => 'Blog',
        'userId'         => $this->session->userdata('sh_userId'),
        'fullName'       => $this->session->userdata('sh_fullName'),
        'accountTypeId'  => $this->session->userdata('sh_accountTypeId'),
        'photo'          => $this->session->userdata('sh_photo'),
        'halaman'        => $this->pagination->create_links(),
        'offset'         => $offset,
        'listblogPost'   => $list_blogPost,
        'listlastblogPost'=> $list_lastblogPost,
        'listblogCategory'=>$list_blogCategory
        );
    $this->template->display_admin('blog_categorypost',$data);
}

由于您的 URL 有两个参数，您需要为该方法设置两个路由。将您的路线更改为

$route['blog/category/(:any)/page'] = 'Blog_Category_Post/page/$1/page';
$route['blog/category/(:any)/page/(:any)'] = 'Blog_Category_Post/page/$1/page/$2';

现在更改配置行 base_url 如下

$config['base_url']  = site_url('blog/category').'/'.$id.'/page';

最后你的page 控制器应该是

    public function page($categoryId){
     $this->db->select('id,categoryId');
     $this->db->from('t_blog_post');
     $this->db->where('categoryId',$categoryId);
     $query= $this->db->get();

    //$jml                        = $this->db->get('t_blog_post');
     $config['base_url']         = site_url('blog/category/').'/'.$categoryId.'/page';
     $config['total_rows']       = $query->num_rows();
     $config['per_page']         = 2; /*Jumlah data yang dipanggil perhalaman*/  
    $config['uri_segment']      = 5;    /*data selanjutnya di parse diurisegmen 3*/
    /*Class bootstrap pagination yang digunakan*/
     $config['full_tag_open']    = "<ul class='pagination pagination-sm' style='position:relative; top:-25px;'>";
     $config['full_tag_close']   ="</ul>";
     $config['num_tag_open']     = '<li>';
     $config['num_tag_close']    = '</li>';
     $config['cur_tag_open']     = "<li class='disabled'><li class='active'><a href='#'>";
     $config['cur_tag_close']    = "<span class='sr-only'></span></a></li>";
     $config['next_tag_open']    = "<li>";
     $config['next_tagl_close']  = "</li>";
     $config['prev_tag_open']    = "<li>";
     $config['prev_tagl_close']  = "</li>";
     $config['first_tag_open']   = "<li>";
     $config['first_tagl_close'] = "</li>";
     $config['last_tag_open']    = "<li>";
     $config['last_tagl_close']  = "</li>";
     $this->pagination->initialize($config);

    if ($this->uri->segment(5)) {
            $offset = $this->uri->segment(5);
        } else {
            $offset = 0;
        }

     $list_blogPost=$this->BlogCategory->get_post($config['per_page'], $offset,$categoryId);
     $list_lastblogPost=$this->BlogCategory->get_last_post();
     $list_blogCategory=$this->BlogCategory->get_category();
     $data=array(
        'title'          => 'Blog',
        'userId'         => $this->session->userdata('sh_userId'),
        'fullName'       => $this->session->userdata('sh_fullName'),
        'accountTypeId'  => $this->session->userdata('sh_accountTypeId'),
        'photo'          => $this->session->userdata('sh_photo'),
        'halaman'        => $this->pagination->create_links(),
        'offset'         => $offset,
        'listblogPost'   => $list_blogPost,
        'listlastblogPost'=> $list_lastblogPost,
        'listblogCategory'=>$list_blogCategory
        );
     $this->template->display_admin('blog_categorypost',$data);
}

现在测试。
