Zend Framework Pagination Class usage detailed _php example

The examples in this article describe the Zend Framework page-class usage. Share to everyone for your reference, specific as follows:

1, pagination class pagination.php, it is best to put this class in the Zend directory

Class Xy_pagination {Private $_navigationitemcount = 10;//navigation bar displays the total number of navigation pages private $_pagesize = NULL;//per page items private $ _align = "right"; Navigation bar display location private $_itemcount = null; Total number of items private $_pagecount = null; Total pages Private $_currentpage = null; Current page Private $_front = null; Front Controller Private $_pageparaname = "page"; Page parameter name private $_firstpagestring = "|<<"; The character displayed on the first page of the navigation bar private $_nextpagestring = ">>"; The character displayed on the previous page in the navigation bar private $_previouspagestring = "<<"; The character that appears on the next page of the navigation bar private $_lastpagestring = ">>|";
         The character that is displayed on the last page of the navigation bar private $_splitstring = "|"; Spacer/Public Function __construct ($itemCount, $pageSize) between page numbers {if (!is_numeric ($itemCount) | |
    (!is_numeric ($pageSize)))
    throw new Exception ("pagination error:not number");
    $this->_itemcount = $itemCount;
    $this->_pagesize = $pageSize;
    $this->_front = Zend_controller_front::getinstance (); $this->_pagecount = ceil ($itemCount/$pageSize);
   Total pages $page = $this->_front->getrequest ()->getparam ($this->_pageparaname); if (Empty ($page) | | (!is_numeric ($page)))
    is empty or not a number, set the current page to 1 {$this->_currentpage = 1;
      else {if ($page < 1) $page = 1;
      if ($page > $this->_pagecount) $page = $this->_pagecount;
    $this->_currentpage = $page; 
  }/** * Back to current page * @param int Current page */Public Function getcurrentpage () {return $this->_currentpage; /** * Return to navigation column * @return string navigation html class= "pagenavigation" * * * Public Function Getnavigation () {$
    Navigation = '; $pageCote = ceil ($this->_currentpage/($this->_navigationitemcount-1))-1; The current page is in the first column $pageCoteCount = ceil ($this->_pagecount/($this->_navigationitemcount-1)); Total page Bar $pageStart = $pageCote * ($this->_navigationitemcount-1) + 1; Page Bar Start Page $pageEnd = $pageStart + $this->_navigationitemcount-1; Stop page in page break if ($this->_PageCount < $pageEnd) {$pageEnd = $this->_pagecount;
    $navigation. = "Total: {$this->_itemcount} {$this->_pagecount}] \ n";
    if ($pageCote > 0)//home navigation {$navigation. = ' $this->_firstpagestring ';
    } if ($this->_currentpage!= 1)//Previous page navigation {$navigation. = ' $this->_previouspagestring '; while ($pageStart <= $pageEnd)//construct the digital navigation area {if ($pageStart = = $this->_currentpage) {$na
      Vigation. = "$pageStart". $this->_splitstring;
      else {$navigation. = ' $pageStart '. $this->_splitstring;
    } $pageStart + +; 
    } if ($this->_currentpage!= $this->_pagecount)//Next page navigation {$navigation. = ' $this->_nextpagestring ';
    } if ($pageCote < $pageCoteCount-1)//pager {$navigation. = ' $this->_lastpagestring ';
    //Add direct navigation box//$navigation. = ';

  return $navigation;  /** * Get navigation bar display navigation Total pages * * @return int navigation bar display navigation total pages/Public function Getnavigationitemcount () {return
  $this->_navigationitemcount; /** * Set navigation bar display navigation Total pages * * @param int $navigationCount: Navigation bar Display navigation total pages/Public function Setnavigationitemcoun ($
    Navigationcount) {if (Is_numeric ($navigationCount)) {$this->_navigationitemcount = $navigationCount; }/** * Settings first display character * @param string $firstPageString first display character/public function setfirstpagestring ($firstP

  ing{$this->_nextpagestring = $nextPageString; /** * Set the setlastpagestring display character * @param string $nextPageString: no page display character */Public function ($lastPageStrin
  g) {$this->_lastpagestring = $lastPageString; /** * Set navigation character display position * @param string $align: Navigation location/Public function setalign ($align) {$align = Strtolowe
    R ($align);
    if ($align = = "Center") {$this->_align = "center";
    }elseif ($align = = "Right") {$this->_align = ' right ';
    }else {$this->_align = "Left"; /** * Set Page parameter name * @param string $pageParamName: Page parameter name/Public function Setpageparamname ($pageParamName
  {$this->_pageparaname = $pageParamName; /** * Get page parameter name * @return String page parameter name */Public Function Getpageparamname () {return $this->_page
  Paraname; /** * Generate navigation link address * @param int $targetPage: Navigation page * @return string link destination address/private function createhref ($targ Etpage = null) {$params = $this->_front->getrequest ()->getparams ();
    $module = $params ["module"];
    $controller = $params ["Controller"];
    $action = $params ["Action"]; $TARGETURL = $this->_front->getbaseurl ().
    /$module/$controller/$action "; foreach ($params as $key => $value) {if ($key!= "Controller" && $key!= "module" && $key!=
      "Action" && $key!= $this->_pageparaname) {$targetUrl. = "/$key/$value";
    } if (Isset ($targetPage))//Specify target page $targetUrl. = "/$this->_pageparaname/$targetPage";
    else $targetUrl. = "/$this->_pageparaname/";
  return $TARGETURL;

 }}?>

2, in the indexcontroller.php in the Indexcontroller function inside call:

Require_once ' zend/pagination.php ';
$Users = new Users ();
$rows = $Users->getadapter ()->fetchone ("SELECT count (*) from the Users where ' role '!= ' admin '); Recorde count
$rows = $Users->fetchall ("' Role '!= ' admin ')->count ();//Total number of query records
$rowsPerPage = 5;// Perpage recordes
$curPage = 1;
if ($this->_request->getparam (' page '))
{
    $curPage = $this->_request->getparam (' page ');
}
Search data and display
$this->view->users = $Users->fetchall ("' Role '!= ' admin '", ' ID desc ', $ Rowsperpage, ($curPage-1) * $rowsPerPage)->toarray ();
$Pager = new Xy_pagination ($rows, $rowsPerPage);
$this->view->pagebar = $Pager->getnavigation ();

3. It's simpler to call pagination in view.

Pagebar?>

Or in the case of a smarty template

<{$pagebar}>
