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 returns some data for invocation
Copy CodeThe code is as follows:
$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,
