Yii Paging Component Usage example analysis, Yii paging instance analysis

The examples in this article describe the usage of yii paging components. Share to everyone for your reference, as follows:

When this case is used, the paging class exists as a component in the YII framework in the form of components.

The action code is as follows:

Public Function Actionindex () {  $user =user::model ();  Use of paging  $count = $user->count ();//Get  The total number of pages $pagesize = 3;//each page displays a record strip  $page =new page ($count, $pagesize);  $sql = "Select * from {{user}} $page->limit";  $info = $user->findallbysql ($sql);  $show _page= $page->fpage ();  $this->renderpartial ("index", Array ("info" = = $info, ' show_page ' = $show _page));}

On the view page, you can traverse info to get information, and output show_page to display a list of pages.

We enclose the page.php code as follows:

<?php/** * Pagination class, in the form of components in the Componnets file */class page {private $total;//The total number of records in the data table private $listRows;//page shows the number of rows private $  Limit  Private $uri; Private $pageNum; Pages private $config =array (' Headers ' and ' Records ', ' prev ' and ' prev ', ' next ' = ' next ', ' first ' = ' home ', ' last ' + ' end ')  );  Private $listNum = 8;   /* * $total * $listRows * * Public function __construct ($total, $listRows =10, $pa = "") {$this->total= $total;   $this->listrows= $listRows;   $this->uri= $this->geturi ($PA); $this->page=!empty ($_get["page"])?   $_get["Page"]: 1;   $this->pagenum=ceil ($this->total/$this->listrows);  $this->limit= $this->setlimit (); } Private Function Setlimit () {return ' Limit '.  $this->page-1) * $this->listrows. ", {$this->listrows}"; } Private Function GetURI ($PA) {$url =$_server["Request_uri"]. ( Strpos ($_server["Request_uri"], '? ')? ': '? ').   $PA;   $parse =parse_url ($url);    if (Isset ($parse ["Query"])) {parse_str ($parse [' query '], $params); Unset ($params["page"]); $url = $parse [' Path '].   Http_build_query ($params);  } return $url;   } function __get ($args) {if ($args = = "Limit") return $this->limit;  else return null;   } Private Function Start () {if ($this->total==0) return 0;  else return ($this->page-1) * $this->listrows+1;  } Private Function End () {return min ($this->page* $this->listrows, $this->total);   } Private Function First () {$html = ';   if ($this->page==1) $html. = ';   else $html. = "Uri}&page=1 ' >{$this->config[" First "]}";  return $html;   } Private Function Prev () {$html = ';   if ($this->page==1) $html. = '; else $html. = "Uri}&page=". ($this->page-1). "'   >{$this->config["prev"} ";  return $html;   } Private Function PageList () {$linkPage = "";   $inum =floor ($this-&GT;LISTNUM/2);    for ($i = $inum; $i >=1; $i-) {$page = $this->page-$i;    if ($page <1) continue;   $linkPage. = "uri}&page={$page} ' >{$page}"; } $linkpage.= "{$this->page}";    for ($i =1; $i <= $inum; $i + +) {$page = $this->page+ $i;    if ($page <= $this->pagenum) $linkPage. = "uri}&page={$page} ' >{$page}";   else break;  } return $linkPage;   } Private Function Next () {$html = ';   if ($this->page== $this->pagenum) $html. = "; else $html. = "Uri}&page=". ($this->page+1). "'   >{$this->config["Next"} ";  return $html;   } private Function Last () {$html = ';   if ($this->page== $this->pagenum) $html. = "; else $html. = "Uri}&page=". ($this->pagenum). "'   >{$this->config["Last"]} ";  return $html;  } Private Function Gopage () {return ''; } function Fpage ($display =array (0,1,2,3,4,5,6,7,8)) {$html [0]=] Total{$this->total}{$this->config["header"]}   "; $html [1]=] Display per page". ($this->end ()-$this->start () +1). "Bar, this page{$this->start ()}-{$this->end ()}Article "; $html [2]=]{$this->page}/{$this->pagenum}Page ";   $html [3]= $this->first ();   $html [4]= $this->prev ();   $html [5]= $this->pagelist ();   $html [6]= $this->next ();   $html [7]= $this->last ();   $html [8]= $this->gopage ();   $fpage = ";   foreach ($display as $index) {$fpage. = $html [$index];  } return $fpage; }}
