Zend Framework Paging class usage in detail, zendframework

This example describes the Zend framework paging class usage. Share to everyone for your reference, 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;//items per page private $_alig n = "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 characters shown on the first page of the navigation bar private $_nextpagestring = ">>"; The characters that appear on the previous page in the navigation bar private $_previouspagestring = "<<"; The next page in the navigation bar shows the characters private $_lastpagestring = ">>|";         The last page in the navigation bar shows the characters private $_splitstring = "|"; Spacing between page numbers/Public function __construct ($itemCount, $pageSize) {if (!is_numeric ($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;  }}/** * Returns the 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 of the page $pageCoteCount = ceil ($this->_pagecount/($this->_navigationitemcount-1)); Total page Bar $pageStart = $pageCote * ($this->_navigationitemcount-1) + 1; Start Page in page bar $pageEnd = $pageStart + $this->_navigationitemcount-1; End page in page bar if ($this->_pagecount < $pageEnd) {$pageEnd = $this->_pAgecount;    } $navigation. = "Total: {$this->_itemcount} bar {$this->_pagecount} page \ n";    if ($pageCote > 0)//home navigation {$navigation. = ' $this->_firstpagestring ';    if ($this->_currentpage! = 1)//previous navigation {$navigation. = ' $this->_previouspagestring '; } while ($pageStart <= $pageEnd)//constructs the digital navigation area {if ($pageStart = = $this->_currentpage) {$navigat      Ion. = "$pageStart". $this->_splitstring;      } else {$navigation. = ' $pageStart '. $this->_splitstring;    } $pageStart + +;    if ($this->_currentpage! = $this->_pagecount)//Next navigation {$navigation. = ' $this->_nextpagestring ';    if ($pageCote < $pageCoteCount-1)//no page navigation {$navigation. = ' $this->_lastpagestring ';    }//Add direct navigation box//$navigation. = ';    August 27, 2008 added error after entering incorrect page number--begin $navigation. = ";    August 27, 2008 added error--end after entering the incorrect page number $navigation. = "";  return $navigation; }/** * Get navigation bar display navigationTotal pages * * @return int navigation bar display total number of navigation pages */Public Function Getnavigationitemcount () {return $this->_navigationitemco  Unt /** * Set the navigation bar to display the total number of navigation pages * * @param int $navigationCount: The navigation bar displays the total number of navigation pages */Public function Setnavigationitemcoun ($naviga    Tioncount) {if (Is_numeric ($navigationCount)) {$this->_navigationitemcount = $navigationCount; }}/** * Set the first page display character * @param string $firstPageString first page display characters */Public function setfirstpagestring ($firstPageString  ) {$this->_firstpagestring = $firstPageString; }/** * Set previous navigation display characters * @param string $previousPageString: Previous page display characters */Public function setpreviouspagestring ($previous  pagestring) {$this->_previouspagestring = $previousPageString;  }/** * Set next page navigation display characters * @param string $nextPageString: Next page display characters */Public function setnextpagestring ($nextPageString)  {$this->_nextpagestring = $nextPageString; /** * Set the non-pager display character * @param string $nextPageString: no page display characters */public function SetlaStpagestring ($lastPageString) {$this->_lastpagestring = $lastPageString; /** * Set Navigation character display location * @param string $align: Navigation position */Public Function setalign ($align) {$align = Strtolower ($alig    n);    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->_pageparanam  E  /** * Generate navigation link address * @param int $targetPage: Navigation page * @return String link Destination address */Private function Createhref ($targetPage        = 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! = "A      Ction "&& $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 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 is easier to call paging in view.

Pagebar?>

Or in the case of smarty templates

<{$pagebar}>
