Pager 分页函数
复制代码 代码如下:
/**
* 构造函数
*
* 如果 $source 参数是一个 TableDataGateway 对象，则 FLEA_Helper_Pager 会调用
* 该 TDG 对象的 findCount() 和 findAll() 来确定记录总数并返回记录集。
*
* 如果 $source 参数是一个字符串，则假定为 SQL 语句。这时，FLEA_Helper_Pager
* 不会自动调用计算各项分页参数。必须通过 setCount() 方法来设置作为分页计算
* 基础的记录总数。
*
* 同时，如果 $source 参数为一个字符串，则不需要 $conditions 和 $sortby 参数。
* 而且可以通过 setDBO() 方法设置要使用的数据库访问对象。否则 FLEA_Helper_Pager
* 将尝试获取一个默认的数据库访问对象。
*
* @param TableDataGateway|string $source
* @param int $currentPage
* @param int $pageSize
* @param mixed $conditions
* @param string $sortby
* @param int $basePageIndex
*
* @return FLEA_Helper_Pager
*/
function FLEA_Helper_Pager(& $source, $currentPage, $pageSize = 20, $conditions = null, $sortby = null, $basePageIndex = 0)
{
$this->_basePageIndex = $basePageIndex;
$this->_currentPage = $this->currentPage = $currentPage;
$this->pageSize = $pageSize;
if (is_object($source)) {
$this->source =& $source;
$this->_conditions = $conditions;
$this->_sortby = $sortby;
$this->totalCount = $this->count = (int)$this->source->findCount($conditions);
$this->computingPage();
} elseif (!empty($source)) {
$this->source = $source;
$sql = "SELECT COUNT(*) FROM ( $source ) as _count_table";
$this->dbo =& FLEA::getDBO();
$this->totalCount = $this->count = (int)$this->dbo->getOne($sql);
$this->computingPage();
}
}

Pager 参数说明
$source 数据库操作类
$currentPage 当前页
$pageSize 每页显示记录数量
$conditions 查询条件
$sortby 排序方式
$basePageIndex 页码基数
Pager 使用示例（实例）
复制代码 代码如下:
$dirname = dirname(__FILE__);
define("APP_DIR", $dirname . "/APP");
define("NO_LEGACY_FLEAPHP", true);
require($dirname."/FleaPHP/FLEA/FLEA.php");
//设置缓存目录
FLEA::setAppInf("internalCacheDir",$dirname."/_Cache");
//链接数据库
$dsn = array(
"driver" => "mysql",
"host" => "localhost",
"login" => "root",
"password" => "",
"database" => "wordpress"
);
FLEA::setAppInf("dbDSN",$dsn);
//读取wp_posts的内容
FLEA::loadClass("FLEA_Db_TableDataGateway");
FLEA::loadClass("FLEA_Helper_Pager");
//FLEA::loadHelper("pager");
class Teble_Class extends FLEA_Db_TableDataGateway {
var $tableName = "wp_posts";
var $primaryKey = "ID";
}
$tableposts =& new Teble_Class();
$pager =& new FLEA_Helper_Pager($tableposts,2,5);
$page = $pager->getPagerData();
print_r($page);

getPagerData 返回一些数据供调用
复制代码 代码如下:
$data = array(
"pageSize" => $this->pageSize,
"totalCount" => $this->totalCount,
"count" => $this->count,
"pageCount" => $this->pageCount,
"firstPage" => $this->firstPage,
"firstPageNumber" => $this->firstPageNumber,
"lastPage" => $this->lastPage,
"lastPageNumber" => $this->lastPageNumber,
"prevPage" => $this->prevPage,
"prevPageNumber" => $this->prevPageNumber,
"nextPage" => $this->nextPage,
"nextPageNumber" => $this->nextPageNumber,
"currentPage" => $this->currentPage,
"currentPageNumber" => $this->currentPageNumber,
);
