问题:

I am looking for a php pagination class, I have used a rather simple one in the past and it is no longer supported.

I was wondering if anyone had any recommendations ?

It seems pointless to build my own when there are probably so many good ones out there.

回答1:

I would suggest Zend_Paginator for the following reasons

  • It's loosely coupled and doesn't require the entire library.
  • The ZF community is larger than the PEAR community and is actively running security audits on code, and releasing maintenance versions.
  • It separates data sources by using the Adapter Pattern, and there are numerous examples of front end UI pattern implementations in the documentation.


回答2:

After more searching I decided that before I use a frameworked version I should fully understand what is involved in a paginator. So I built one myself. Thanks for the suggestions though!



回答3:

Have you tried PEAR::Pager? Usage examples here.



回答4:

you can try this: Zebra_Pagination, a generic, Twitter Bootstrap compatible, pagination class written in PHP check the link below: 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;
    }
}

Use:

$pagination = new Pagination($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();

Result:

<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>

    }

Its Very possible that your SQL SELECT statement query may 1000 result into thousand of records. But its is not good idea to display all the results on one page. So we can divide this result into many pages as per requirement as pagination Class .

PAGINATE DATA WITH PAGINATION CLASS VERY EASY

pagination Class helps to generate paging
