需求：分页之后保持原先的查询条件

$dao = M('News');
$condition = array();
$provinceid = intval($_GET['province']);
$type =  intval($_GET['type']);
		
$count = $dao->where($condition)->count();
$p = new page($count, 20);
$dataList = $dao->where($condition)->select();

/* 分页参数 */
$conditions = array();
$type && $conditions['type'] = $type;
$provinceid && $conditions['province'] = $provinceid;
foreach($conditions as $key=>$val) { //给分页类传入参数（给分页类的parameter属性赋值）
	$p->parameter   .= '&'."$key=".urlencode($val);
}
$page = $p->show();

if($dataList!=false){
	$this->assign('pageBar', $page);
	$this->assign('dataList', $dataList);
}
