PHP分頁類

Question

我正在尋找一個php分頁類，我已經使用了一個相當簡單的過去，它不再支持。

我想知道是否有人有任何建議？

當有可能有這麼多好東西的時候，建立我自己似乎毫無意義。

Answer 1

更多的搜索後，我決定之前，我使用frameworked版本我應該充分了解什麼是參與一個分頁程序。所以我自己建了一個。感謝您的建議，但！

Answer 2

你試過PEAR::Pager？用法示例here。

Answer 3

我建議Zend_Paginator，原因如下

• 它是鬆散耦合的，不需要整個庫。
• ZF社區比PEAR社區還要大，並且正在積極地對代碼進行安全審計，併發布維護版本。
• 它使用適配器模式分離數據源，並且文檔中有許多前端UI模式實現的示例。

Answer 4

你可以試試這個： Zebra_Pagination，通用，Twitter的引導兼容，分頁用PHP編寫的 檢查類別下面的鏈接： http://stefangabos.ro/php-libraries/zebra-pagination

// pagination class 
class Pagination 
{ 
    // database handle 
    private $dbh; 

    // total records in table 
    private $total_records; 

    // limit of items per page 
    private $limit; 

    // total number of pages needed 
    private $total_pages; 

    // first and back links 
    private $firstBack; 

    // next and last links 
    private $nextLast; 

    // where are we among all pages? 
    private $where; 

    public function __construct($dbh) { 
     $this->dbh = $dbh; 
    } 

    // determines the total number of records in table 
    public function totalRecords($query, array $params) 
    { 
     $stmt = $this->dbh->prepare($query); 
     $stmt->execute($params); 
     $this->total_records = $stmt->fetchAll(PDO::FETCH_COLUMN)[0]; 

     if (!$this->total_records) { 
      echo 'No records found!'; 
      return; 
     } 
    } 

    // sets limit and number of pages 
    public function setLimit($limit) 
    { 
     $this->limit = $limit; 

     // determines how many pages there will be 
     if (!empty($this->total_records)) { 
      $this->total_pages = ceil($this->total_records/$this->limit); 
     } 
    } 

    // determine what the current page is also, it returns the current page 
    public function page() 
    { 
     $pageno = (int)(isset($_GET['pageno'])) ? $_GET['pageno'] : $pageno = 1; 

     // out of range check 
     if ($pageno > $this->total_pages) { 
      $pageno = $this->total_pages; 
     } elseif ($pageno < 1) { 
      $pageno = 1; 
     } 

     // links 
     if ($pageno > 1) { 
      // backtrack 
      $prevpage = $pageno -1; 

      // 'first' and 'back' links 
      $this->firstBack = "<div class='first-back'><a href='$_SERVER[PHP_SELF]?pageno=1'>First</a> <a href='$_SERVER[PHP_SELF]?pageno=$prevpage'>Back</a></div>"; 
     } 

     $this->where = "<div class='page-count'>(Page $pageno of $this->total_pages)</div>"; 

     if ($pageno < $this->total_pages) { 
      // forward 
      $nextpage = $pageno + 1; 

      // 'next' and 'last' links 
      $this->nextLast = "<div class='next-last'><a href='$_SERVER[PHP_SELF]?pageno=$nextpage'>Next</a> <a href='$_SERVER[PHP_SELF]?pageno=$this->total_pages'>Last</a></div>"; 
     } 

     return $pageno; 
    } 

    // get first and back links 
    public function firstBack() 
    { 
     return $this->firstBack; 
    } 

    // get next and last links 
    public function nextLast() 
    { 
     return $this->nextLast; 
    } 

    // get where we are among pages 
    public function where() 
    { 
     return $this->where; 
    } 
} 

用途：

$pagination = new Pagination($dbh); 
$pagination->totalRecords('SELECT COUNT(*) FROM `photos` WHERE `user` = :user', array(':user' => $_SESSION['id'])); 
$pagination->setLimit(12); 
$pagination->page(); 
echo $pagination->firstBack(); 
echo $pagination->where(); 
echo $pagination->nextLast(); 

結果：

<div class='first-back'><a href='/xampp/web_development/new_study_2014/imagebox2016/app/public/test.php?pageno=1'>First</a> <a href='/xampp/web_development/new_study_2014/imagebox2016/app/public/test.php?pageno=3'>Back</a></div> 
<div class='page-count'>(Page 4 of 6)</div> 
<div class='next-last'><a href='/xampp/web_development/new_study_2014/imagebox2016/app/public/test.php?pageno=5'>Next</a> <a href='/xampp/web_development/new_study_2014/imagebox2016/app/public/test.php?pageno=6'>Last</a></div> 

Answer 6

它很可能是您的SQL SELECT語句查詢可能會導致1000條記錄。但是在一個頁面上顯示所有結果並不是一個好主意。所以我們可以根據需要將這個結果分成許多頁作爲分頁類。與分頁類VERY EASY
