Question

我认为从数据库获取所有数据，我不会在我的代码中进行分页。

我会尝试这种方式在我的网站上进行分页，但它不会显示分页。

视图如下： -

<ol class="timeline2 clear">
  <li class="spine">

  </li>

  <?php 
  $counter=0;
  //print_r($response);
  foreach ($response as $row) { 
  if($counter % 2 == 0){$class= "left";} else $class="right";
  ?>

   <li class="<?=$class ?>">
    <i class="pointer"></i>
    <div class="unit">

      <!-- Story -->
      <div class="storyUnit">
        <div class="imageUnit">
         <? if (empty($row->pic)) { ?>
          <a href="#"><img width="32" height="32" alt="" src="images/nopic.png"></a>
          <? } else  { ?>
          <a href="#"><img width="32" height="32" alt="" src="uploads/<?php echo $row->pic; ?>"></a>
          <div id="delpost" style="float:left">
          <a href="./myaccount/deletePostInProfile/<?=$row->ev_id;?>" id="deletepost">X</a>
          </div>
          <? } ?>
          <div class="imageUnit-content">
            <h4><a href="./myaccount/profile/<?php echo $row->id; ?>"><?php echo $row->fullname; ?></a></h4>
            <p><?php echo $row->ev_date ?></p>
          </div>

        </div>

        <p> <?php echo $row->ev_text; ?><br />
        <? if (!empty($row->ev_pic)) { ?>
        <img src="uploads/<?php echo $row->ev_pic ?>" width="250" height="250"</p>
        <? } ?></p>

      </div>
      <!-- / Story -->

      <!-- Units -->
      <ol class="storyActions" id="storyActions<?php echo $row->ev_id; ?>">
<?
$selectComment = mysql_query("select * from comment,users where 
comment.co_postid = '".$row->ev_id."'
and comment.co_userid = users.id order by co_date DESC ");
while($rows=mysql_fetch_array($selectComment)){
?>
      <div id="resultcomment<?php echo $row->ev_id; ?>"></div>
      <div id="resultcomment" style="border-top:1px solid #fff;">
      <a href="./myaccount/profile/<?php echo $rows['id']; ?>">
      <img src="uploads/<?=$rows["pic"];?>" width="32" height="32" class="rightc" />
      </a>
      <b><a href="./myaccount/profile/<?php echo $rows['id']; ?>"><?=$rows["fullname"]; ?></a></b>
      <span>&nbsp;&nbsp;</span>
      <span><?=$rows["co_comment"]; ?></span>
      <br />
      <span class="commentdate"><?=$rows["co_date"]; ?></span></br></div>
<? } ?>      

      <form action="" method="post" accept-charset="utf-8">
       <input type="text" class="commentprofile" id="comment<?php echo $row->ev_id; ?>" name="comment<?php echo $row->ev_id; ?>" size="41" />
       <input type="hidden" id="postid<?php echo $row->ev_id; ?>" name="postid<?php echo $row->ev_id; ?>" size="41" value="<?php echo $row->ev_id; ?>" />
       <button type="button" id="submit" onclick="add_comment(<?php echo $row->ev_id; ?>)">ارسل</button>
       </form>

      </ol>
      <!-- / Units -->

    </div>
  </li>

   <?php $counter++; } ?>
   <div class="clear"></div>
</ol>

<? } ?>

    <div>

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

    </div>

和我的控制员： -

public function profile($user_id) {

        $check  = new User();
        $ex = $check->where('id',$user_id)->count();
        if( $ex == 0){ redirect('./home'); }
        else {
        $user = new User($user_id);


/************************************** Post *******************************************************************/
        $this->load->model('blog');

        if(isset($_POST['post'])){
        // Config setup
        $config['base_url'] = base_url().'/myaccount/profile/'.$user_id.'/';
        $config['total_rows'] = 20;
        $config['per_page'] = 10;
        $config['num_links'] = 5;
        // Initialize
        $this->pagination->initialize($config);

        if(strlen($_FILES['inputUpProfile']['name']) > 0) 
        {
        $pic = $this->do_upload('inputUpProfile');

        if ($this->input->post('post') == ''){$type="image";} else {$type="image-with-text";}
        }

        else {$pic = ""; $type = "text"; }

            $result = $this->blog->addPost($_SESSION['user_id'], $type  , $this->input->post('post'),$pic);
        }
        if(isset($_SESSION['user_id']) || !empty($_SESSION['user_id'])){
        $result = $this->blog->getPost($user_id, 0 , 10);
        $this->template->build("profile" , array("response"=>$result));     
        }
        else{
        $this->template->build('registration_view',$this->data);
        }


        $this->data['user'] = $user;
        $this->data['errors'] = $this->errors;
        $this->template->set_layout('myaccount');
        $this->template->build('profile',$this->data);


        }
    }

模块： -

function getPost($user_id, $from, $to) {
      $query = $this->db->query("SELECT * FROM events,users 
      where events.ev_user_id  = '".$user_id."'
      and events.ev_user_id = users.id  
      order by events.ev_date DESC limit 10");



    return $query->result();

}

为什么分页不会显示在我的网站上？

Answer 1

初始化分页后在控制器中：

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

然后在您希望显示分页链接的视图中：

echo $pagination_links;

您试图在视图中回显它们而不先在控制器中创建它们。文档中的示例有点不好，因为它只是让您在控制器本身中回显它们。

codeigniter中的分页不起作用
