Detailed explanation of paging examples using CLinkPager in Yii, yiiclinkpager

This article mainly explains how to use CLinkPager for paging in YII. Here we use objects to define paging:

First customize LinkPager in components and inherit CLinkPager

The specific code is as follows:

<&#63;php
/**
 * CLinkPager class file.
 *
 * @link http://www.yiiframework.com/
 * @copyright Copyright &copy; 2008-2011 Yii Software LLC
 * @license http://www.yiiframework.com/license/
 */

/**
 * CLinkPager displays a list of hyperlinks that lead to different pages of target.
 *
 * @version $Id$
 * @package system.web.widgets.pagers
 * @since 1.0
 */
class LinkPager extends CLinkPager
{
 const CSS_TOTAL_PAGE='total_page';
 const CSS_TOTAL_ROW='total_row';
 
 /**
 * @var string the text label for the first page button. Defaults to '<< First'.
 */
 public $totalPageLabel;
 /**
 * @var string the text label for the last page button. Defaults to 'Last >>'.
 */
 public $totalRowLabel;
 
 /**
 * Creates the page buttons.
 * @return array a list of page buttons (in HTML code).
 */
 protected function createPageButtons()
 {
 

    $this->maxButtonCount=8; 
    $this->firstPageLabel="首页";
    $this->lastPageLabel='末页'; 
    $this->nextPageLabel='下一页';
    $this->prevPageLabel='上一页'; 
    $this->header="";
 
 if(($pageCount=$this->getPageCount())<=1)
  return array();
 
 list($beginPage,$endPage)=$this->getPageRange();
 $currentPage=$this->getCurrentPage(false); // currentPage is calculated in getPageRange()
 $buttons=array();
 
 // first page
 $buttons[]=$this->createPageButton($this->firstPageLabel,0,self::CSS_FIRST_PAGE,$currentPage<=0,false);

 // prev page
 if(($page=$currentPage-1)<0)
  $page=0;
 $buttons[]=$this->createPageButton($this->prevPageLabel,$page,self::CSS_PREVIOUS_PAGE,$currentPage<=0,false);

 // internal pages
 for($i=$beginPage;$i<=$endPage;++$i)
  $buttons[]=$this->createPageButton($i+1,$i,self::CSS_INTERNAL_PAGE,false,$i==$currentPage);

 // next page
 if(($page=$currentPage+1)>=$pageCount-1)
  $page=$pageCount-1;
 $buttons[]=$this->createPageButton($this->nextPageLabel,$page,self::CSS_NEXT_PAGE,$currentPage>=$pageCount-1,false);

 // last page
 $buttons[]=$this->createPageButton($this->lastPageLabel,$pageCount-1,self::CSS_LAST_PAGE,$currentPage>=$pageCount-1,false);
 
 // 页数统计
 $buttons[]=$this->createTotalButton(($currentPage+1)."/{$pageCount}",self::CSS_TOTAL_PAGE,false,false);
 
 // 条数统计
 $buttons[]=$this->createTotalButton("共{$this->getItemCount()}条",self::CSS_TOTAL_ROW,false,false);

 return $buttons;
 }
 
 protected function createTotalButton($label,$class,$hidden,$selected)
 {
 if($hidden || $selected)
  $class.=' '.($hidden &#63; self::CSS_HIDDEN_PAGE : self::CSS_SELECTED_PAGE);
 return '<li class="'.$class.'">'.CHtml::label($label,false).'</li>';
 }
 
 /**
 * Registers the needed client scripts (mainly CSS file).
 */
 public function registerClientScript()
 {
 if($this->cssFile!==false)
  self::registerCssFile($this->cssFile);
 }
 
 /**
 * Registers the needed CSS file.
 * @param string $url the CSS URL. If null, a default CSS URL will be used.
 */
 public static function registerCssFile($url=null)
 {
 if($url===null)
  $url=CHtml::asset(Yii::getPathOfAlias('application.components.views.LinkPager.pager').'.css');
 Yii::app()->getClientScript()->registerCssFile($url);
 }
}

Define CSS styles

/**
 * 翻页样式
 */
.page_blue{
 margin: 3px;
 padding: 3px;
 text-align: center;
 font: 12px verdana, arial, helvetica, sans-serif;
}
ul.bluePager,ul.yiiPager
{
 font-size:11px;

}

Operation in controller:

//分页操作
$criteria=new CDbCriteria;
$criteria->order='id DESC';
$criteria->select=array('id','uid','username','title','thumb','url','clicks','time','dateline','countfavorite','quality');
$criteria->condition=$sql;
$total = Video::model()->count($criteria);

$pages = new CPagination($total);  
$pages->pageSize=self::PAGE_SIZE;
$pages->applyLimit($criteria);
  
$list = Video::model()->findAll($criteria);

$title = CommonClass::model()->find(array(
 'select'=>array('cname'),
 'condition'=>'id = '.$id,
));  

$this->render('application.views.video.list',array(
 'array'=>$array,
 'arr'=>$arr,
 'result'=>$result,
 'list'=>$list,
 'pages'=>$pages,
 'title'=>$title,
));

is quoted in views/video/list.php:

<&#63;php
 $this->widget('LinkPager', array('pages' => $pages,));
 &#63;>

Yii framework is integrated with warp. How to do data paging using mysql database?

It’s the same... The framework only speeds up development efficiency... Which step are you stuck at? Specifically... I posted the code and you can’t learn anything. You will forget it soon... Solve it step by step by yourself. ·Only remember the prison··

Yii paging problem, use it urgently

SQL uses limit and offset. Use $pages = new CPagination ();
for pagination
