$偏移量不能用于分页codeigniter

我想实现分页到我的searchresults页面。我昨天问过这个问题没有成功Records not limited on searchpage using codeigniter pagination

和我现在的问题有点不同。

形势

我的分页链接都工作，并且我看到URL的变化是这样的：http://example.com/home/searchresults/2（用于分页的第二页）等但所有的SearchResult所显示。当我将限制编辑为1时，我得到更多链接，因此工作正常。

问题

可能是什么这个愚蠢的问题呢？我认为这与我的TOTAL_ROWS

我控制器做：

function searchresults() 
    { 
     $this->breadcrumbs->page = array('link'=> base_url().'home/search' ,'title' => 'Bedrijven Zoeken');    
     $this->breadcrumbs->method = array('link'=> base_url().'home/searchresults' ,'title' => 'Zoekresultaten'); 
     $data['breadcrumbs'] = $this->breadcrumbs->get(); 
     $match = $this->input->post('search'); 
     if(strlen($this->input->post('cookie')) > 0){ $match2 = $this->input->post('cookie'); } else{ $match2 = '9101'; } 

     $this->load->library('pagination'); 

     $limit = 4; 
     $offset=($this->uri->segment(3)) ? $this->uri->segment(3) : 0; 
     $config['base_url'] = base_url().'home/searchresults/'; 
     $config['total_rows'] = count($this->bedrijven_model->get_search($match, $match2, $limit, $offset)); 
     $config['per_page'] = $limit; 
     $config['use_page_numbers'] = TRUE; 
     $config['num_links'] = 5; 

     $this->pagination->initialize($config); 
     $offset = $this->uri->segment(3); 
     $data['links'] = $this->pagination->create_links(); 
     //$data['query'] = $this->bedrijven_model->get_search($match, $match2, 2147483647, 0); /*large number as limit to retrieve all the rows*/   
     $data['query_curr'] = $this->bedrijven_model->get_search($match, $match2, $config['per_page'], $this->uri->segment(3)); 
     $this->load->view('views/header'); 
     $this->load->view('views/searchresults', $data); 
     $this->load->view('views/footer'); 
    }

我的模型：

function get_search($match, $match2, $limit, $offset=0) 
{ 
    if(!isset($_SESSION)) 
    { 
    session_start(); 
    }; 
    /* 
    $string = implode($_SESSION['postcodes'], '|'); 
    $string2 = $_SESSION['searched_post_code']; 
    */ 
    $postcodes = (is_array($_SESSION['postcodes']) ? $_SESSION['postcodes'] : array()); 
    $postcodes[] = $_SESSION['searched_post_code']; 
    $postcodes = array_filter(filter_var_array($postcodes, FILTER_VALIDATE_INT)); 
    $string = join(',', $postcodes); 

     if (!isset($_COOKIE['cookie'])) { 

      $query = "SELECT * FROM (`bedrijfcategorieen`) 
      JOIN `bedrijven` ON `bedrijfcategorieen`.`idbedrijven` = `bedrijven`.`idbedrijven` 
      JOIN `categorieen` ON `bedrijfcategorieen`.`idcategorieen` = `categorieen`.`idcategorieen` 
      WHERE (`Bedrijfsnaam` LIKE '%".$this->input->post('search')."%' 
      OR `Plaats` LIKE '%".$this->input->post('search')."%' 
      OR `Telefoonnummer` LIKE '%".$this->input->post('search')."%' 
      OR `Email` LIKE '%".$this->input->post('search')."%' 
      OR `Website` LIKE '%".$this->input->post('search')."%' 
      OR `Profiel` LIKE '%".$this->input->post('search')."%' 
      OR `Adres` LIKE '%".$this->input->post('search')."%' 
      OR `Categorie` LIKE '%".$this->input->post('search')."%') 
      AND (Postcode IN ($string)) 

      GROUP BY `Categorie`, `bedrijfcategorieen`.`idbedrijven`"; 
      $query = $this->db->query($query); 
      $this->db->limit($limit, $offset); 
      echo '<pre>'; 
      echo '</pre>'; 
      $result = $query->result_array(); 
      return $result; 
     }

我希望有人能帮助我与此有关。我现在挣了近3个小时。

你需要你的极限/在$query字符串内偏移：

$query = "SELECT * FROM (`bedrijfcategorieen`) 
     JOIN `bedrijven` ON `bedrijfcategorieen`.`idbedrijven` = `bedrijven`.`idbedrijven` 
     JOIN `categorieen` ON `bedrijfcategorieen`.`idcategorieen` = `categorieen`.`idcategorieen` 
     WHERE (`Bedrijfsnaam` LIKE '%".$this->input->post('search')."%' 
     OR `Plaats` LIKE '%".$this->input->post('search')."%' 
     OR `Telefoonnummer` LIKE '%".$this->input->post('search')."%' 
     OR `Email` LIKE '%".$this->input->post('search')."%' 
     OR `Website` LIKE '%".$this->input->post('search')."%' 
     OR `Profiel` LIKE '%".$this->input->post('search')."%' 
     OR `Adres` LIKE '%".$this->input->post('search')."%' 
     OR `Categorie` LIKE '%".$this->input->post('search')."%') 
     AND (Postcode IN ($string)) 
     GROUP BY `Categorie`, `bedrijfcategorieen`.`idbedrijven` 
     LIMIT ".$offset.", ".$limit; 

     $result = $this->db->query($query); 
     return $result->result_array();

我得到这个错误http://i.imgur.com/FxmjLVA.png只是看看它。 –

尝试将GROUP BY设置为低于GROUP BY - 查看更新的代码。 – Mudshark

现在几乎相同的错误。 http://i.imgur.com/6jNQz6J.png –

$this->db->limit仅适用于活动记录。总之，您的查询更改为此

$query = "SELECT * FROM (`bedrijfcategorieen`) 
     JOIN `bedrijven` ON `bedrijfcategorieen`.`idbedrijven` = `bedrijven`.`idbedrijven` 
     JOIN `categorieen` ON `bedrijfcategorieen`.`idcategorieen` = `categorieen`.`idcategorieen` 
     WHERE (`Bedrijfsnaam` LIKE '%".$this->input->post('search')."%' 
     OR `Plaats` LIKE '%".$this->input->post('search')."%' 
     OR `Telefoonnummer` LIKE '%".$this->input->post('search')."%' 
     OR `Email` LIKE '%".$this->input->post('search')."%' 
     OR `Website` LIKE '%".$this->input->post('search')."%' 
     OR `Profiel` LIKE '%".$this->input->post('search')."%' 
     OR `Adres` LIKE '%".$this->input->post('search')."%' 
     OR `Categorie` LIKE '%".$this->input->post('search')."%') 
     AND (Postcode IN ($string)) 
     GROUP BY `Categorie`, `bedrijfcategorieen`.`idbedrijven` 
     LIMIT $offset,$limit"; 
     $query = $this->db->query($query);

一件事，没有必要使用$这 - > DB->限制
