Question

如果我点击下一个数字链接，我对我的观点有分页效果很好。

1 2 >

因此，如果我点击2，它会在第二页上显示正确的结果。但现在，如果我想回到1而不是重定向我。即使有链接3比我不能来2。

这是我的代码：

控制器：

function list_providers()
{

    $admin_session_data= $this->session->userdata('user_logged_in');

    $this->load->model('/admin/provider_model');
    $this->load->library('pagination');
    $this->load->helper('url');

    $config['base_url'] = base_url()."index.php/admin/provider/list_providers/";
    $config['total_rows'] = $this->provider_model->countprovider();
    $config['per_page'] = 3;
    $config['creat_link'] = 1;
    $config['first_link'] = 'First';
    $config['last_link'] = 'Last';

    $this->pagination->initialize($config);
    $offset=($this->uri->segment(4)) ? $this->uri->segment(4) : 0;
    $data['list']= $this->provider_model->listproviders($config['per_page'],$offset);

    //$data['customer']= $this->provider_model->getcustomer_data($config['per_page'],$this->uri->segment(3));


    if(!empty($data))
    {   
        $this->load->view('admin/admin_header',$admin_session_data); 
        $this->load->view('admin/admin_top_nav',$admin_session_data); 
        $this->load->view('admin/admin_left',$admin_session_data);
        $this->load->view('admin/provider_list',$data);
        $this->load->view('admin/admin_footer',$admin_session_data);
    }

}

型号：

function listproviders($num,$offset)
{
    $this->load->library('pagination');

    //$query=$this->db->get_where('users', array('user_role_id'=>'3'));
    $query=$this->db->get('users',$num,$offset);

    // return result set as an associative array
    return $query->result_array();
}


function countprovider()
{
    $this->load->library('pagination');
    $query=$this->db->count_all_results('users');
    return $query;
}

我的分页显示如下：1 2＆gt;

请看问题在哪里。

我对您的控制器和型号进行了一些更改。更改被评论：

<强>控制器

// admin/provider/list_providers/3 <- Offset number
function list_providers($offset = null)
{    
    $admin_session_data= $this->session->userdata('user_logged_in');

    // Load models/libraries/helpers
    $this->load->model('admin/provider_model');
    $this->load->library('pagination');
    $this->load->helper('url');

    // Pagination config
    $config['base_url'] = site_url('index.php/admin/provider/list_providers') . '/';
    $config['total_rows'] = $this->provider_model->countprovider();
    $config['per_page'] = 3;
    // $config['creat_link'] = 1; <-- This is not a valid option
    $config['first_link'] = 'First';
    $config['last_link'] = 'Last';

    // Init config
    $this->pagination->initialize($config);

    // If the pagination library doesn't recognize the current page add:
    $this->pagination->cur_page = $offset;

    $data['list']= $this->provider_model->listproviders($config['per_page'],$offset);

    if(!empty($data))
    {   
        $this->load->view('admin/admin_header',$admin_session_data); 
        $this->load->view('admin/admin_top_nav',$admin_session_data); 
        $this->load->view('admin/admin_left',$admin_session_data);
        $this->load->view('admin/provider_list',$data);
        $this->load->view('admin/admin_footer',$admin_session_data);
    }
}

<强>模型

function listproviders($num,$offset)
{
    // $this->load->library('pagination'); <-- There is no need for this
    $query = $this->db->get('users', $num, $offset);

    // Check if pages where found
    if ($query->num_rows() > 0)
    {
        return $query->result_array();
    }
    else
    {
        return FALSE;
    }

}


function countprovider()
{
    // $this->load->library('pagination'); <-- There is no need for this
    return $this->db->count_all_results('users');
}

直接从库创建链接.. 像这样......

$data['links']= $this->pagination->create_links();

在视野中给出类似

的内容

<div align="center" style="margin-top:10px;background-color: #F1F8E0">
       <?php echo $links; ?>
</div>

修改

示例代码：

function __construct() { parent::__construct(); $this->load->helper('array'); $this->load->helper('url'); $this->load->helper('html'); $this->load->helper('form'); $this->load->library('form_validation'); $this->load->library('pagination'); $this->load->library('session'); $this->load->model('listing','',TRUE); } // Shows pagination function index($uri_segment="3") { $config['base_url'] = base_url('index.php/listing_controller/index'); $config['total_rows'] = $this->listing->get_rows(); $config['per_page'] = 5; $config['uri_segment'] = 3; $this->pagination->initialize($config); $output['op']=$this->listing->get_paging_data($config['per_page'],$this->uri->segment(3)); $output['links']= $this->pagination->create_links(); $this->load->view('listing_view',$output); }

视图文件中的代码段显示在上面

分页在codeigniter中无法正常工作
