Examples of using PHP paging code with smarty

/**
 * Pagination class
*/
class Pager {
 var $total; // Total number of records
 var $pageSize; // Number of records displayed on each page
 var $currentPage; // Current page number
 var $offset; // Record offset
 var $pageTotal; // Total number of pages
 var $numberOffset = 5; // Page number offset
 var $request = ""; // Page request Parameters
//=================
//Fn: Pager
//Function: Constructor
//============== ====
public function __construct ($total, $pageSize, $currentPage, $request = "") {
 $this->total = $total;
 $this->pageSize = $pageSize;
 $this ->pageOffset();
 $this->pageTotal();
 $this->currentPage($currentPage);
 $this->request = $request;
 }
//===== ============
//Fn: pageOffset
//Function: Database record offset
//=================
 public function pageOffset() {
 return $this->offset = $this->pageSize * ($this->currentPage - 1);
}

//============ =====
//Fn: pageTotal
//Function: Calculate the total number of pages
//==================
 public function pageTotal() {
 return $ this->pageTotal = ceil($this->total / $this->pageSize);
 }

//=================
//Fn : currentPage
//Function: Set the number of pages
//=================
 public function currentPage($currentPage) {
 if (isset($currentPage)) {
 $this->currentPage = intval($currentPage);
 } else {
 $this->currentPage = 1;
 }
 return $this->currentPage;
 }
//======= ==========
//Fn: nextPage
//Function: Jump to the next page
//=================
 public function nextPage() {
 // Display the number of records
 $link = "Total {$this->total} records ";

 // Page step size
 $stepPage = $this->currentPage ? ceil($ this->currentPage / $this->numberOffset) : 1;

 // Number page setting
 $numberPage = ($this->pageTotal > $this->numberOffset) ? $this-> numberOffset : $this->pageTotal;

 // Only one page
 if ($this->total pageSize) {
 $link .= "[Home]|[Last Page] ";
 } else {
 // Set the total number of pages and the current page
 $link .= "Page {$this->currentPage}/{$this->pageTotal} ";

 // Home page
 $link .= "request}>[Home] ";

 // Next column
 if ($stepPage > 1) {
 $lastIndex = ($stepPage - 1) * $this->numberOffset;
 $link .= "request}>[";
 }
 $link .="request}>[";
 }
 $link .= "[" . ($j+1) . "]";
 }
 }
 //Next page
 if ($this->currentPage  pageTotal){
 $nextPage = $this->currentPage + 1;
 $link .= "request}>[ >]";
 }

 // Next column
 if ($stepPage total) {
 $nextPage = $stepPage * ($this->numberOffset + 1) ;
 if ($nextPage pageTotal) {
 $link .= "request}>[> ;>]";
 }
 }
 // Last page
 if ($this->currentPage pageTotal) {
 $link .= "..pageTotal}{$this->request}>[Last page]";
 }

 }
 return $link;
 }
}
?>

Second, PHP paging class calling example:

1. Get the number of pages returned by the URL:

$cur_page = 1;
if (isset($_GET["pageNo"])) {
 $cur_page = $_GET["pageNo"];
 }

2, Create pagination object:

$nums: the total number of certain data
$page_size: the number displayed on each page
$cur_page: the current page number
$request: other optional URL request parameters
$pager = new Pager($nums, $page_size , $cur_page, $request);

3, smarty assignment:

$show = Get the data to be displayed
$this->tpl->assign('numlink', $pager->nextPage()); // Get the paging list
$this-> ;tpl->assign('data',$show);

Pagination effect:

The above paging code does not implement url redirection, which exposes all the information passed in the address bar. You can improve it.
