分頁不能在codeigniter中工作

我在CodeIgniter中工作。我想爲動態記錄創建分頁。所以我寫如下代碼：分頁不能在codeigniter中工作

$config = array(); 
    $config["base_url"] = base_url() . "employer/search_user"; 

    $config["per_page"] = 3; 
    $config['use_page_numbers'] = TRUE; 

    $config['cur_tag_open'] = '&nbsp;<a class="current">'; 
    $config['cur_tag_close'] = '</a>'; 
    $config['next_link'] = 'Next'; 
    $config['prev_link'] = 'Previous'; 


    if($this->uri->segment(3)){ 
     $page = ($this->uri->segment(3)) ; 
    } 
    else{ 
      $page = 1; 
    } 

    $query = "select sn.*,u.first_name,u.last_name,u.email,u.phone,group_concat(DISTINCT s.skill) as sk,group_concat(DISTINCT c.name) as ct from 
       users as u 
       left join snapshot as sn on sn.user_id = u.user_id 
       left join industry as ind on ind.ind_id = sn.industry 
       left join city c ON(FIND_IN_SET(c.city_id, sn.current_location) > 0) 
       left join skill s ON(FIND_IN_SET(s.skill_id, sn.skill) > 0) 
       where ".$where." u.group_id = 3 group by u.user_id limit ".$config["per_page"]; 
    $data['users'] = $this->admin_model->query($query); 

    $row = count($data['users']); 
    $config["total_rows"] = $row; 
    $config['num_links'] = $row; 
    $this->pagination->initialize($config); 
    $data["links"] = $this->pagination->create_links(); 

    $data['main_content']="employer/search_user"; 
    $this->load->view('employer/template', $data);

在這裏，我有3個記錄在頁面但分頁鏈接不顯示。我在構造函數中包含分頁庫。我在$data["links"]這個變量中沒有找到。

那麼，我必須糾正我的代碼？我的代碼有什麼問題？

$配置[ 「NUM_LINKS」]是將顯示分頁鏈接的數量。例如。 $ config ['num_links'] = 3然後 prev 1 2 3 next ,,,,如果它的4則prev 1 2 3 4 next – Calvin

對於$ config [「total_rows」] = $ row; 您只能得到3.因爲您在查詢中設置了限制。請爲總行無限制地寫另一個查詢，我認爲這將解決您的問題。

下面是我的分頁代碼

$config = array(); 
    $config["base_url"] = base_url() . "crm/crm/contactmgmt/modid/" . $modid; 
    if($this->input->post('Search')=='Search'){ 
     $data['pn']=$data1['pn']=$this->input->post('sel_prod'); 
     //echo "hello"; 
    } 
    $config["total_rows"] = $this->Crm_model->record_count_unsubinst(); 
    $config["per_page"] = 6; 
    $this->load->config('pagination'); 
    $config["uri_segment"] = 6; 
    $config['enable_query_strings']='true'; 

    $data['activeTab'] = "View"; 

    $this->pagination->initialize($config); 
    $page = ($this->uri->segment(6)) ? $this->uri->segment(6) : 0; 
    $data['query'] = $this->Crm_model->listUnsubscribedInstn($config["per_page"], $page); 
    $data["link"] = $this->pagination->create_links(); 
    $data["links"]=$data["link"]; 
    $data["cnt"]=$config["total_rows"]; 
    $data["sno"]=$this->uri->segment(6);

你需要在查詢中使用LIMIT和OFFSET。例如

$config['per_page'] = 3; 
$config['uri_segment'] = 4; // This is the current page 

$offset = 0; 
if ($this->uri->segment($config['uri_segment']) != "") { 
    $offset = $this->uri->segment($config['uri_segment']); 
} 

$limit = $config['per_page']; 

$sql = "SELECT `field_name` FROM `table_name` WHERE `table_name`.field_name = ?"; 

if($limit != "") { 
    $sql .= "LIMIT $limit "; 
} 

if($offset != "") { 
    $sql .= "OFFSET $offset"; 
} 

$result = $this->db->query($sql, array($field_data));

希望這有助於
