用数组array代替CActiveRecord构建CArrayDataProvider

当需要构建 GridView的时候；

常常用 CArrayDataProvider 或者 CActiveDataProvider

这是就需要一个CActiveRecord

比如：

857         $sql = "SELECT * FROM zhuanli_applicantCount where kId=:kId order by percentage desc";

858

$rawData= model_applicant::model()->findAllBySql($sql,array('kId'=>$KDValue));

859         $IDARRAY = array();

860

861         $paginationTop = new CPagination(sizeof($rawData));

862         $paginationTop->pageVar = 'page';

863         $paginationTop->pageSize= 10;

864         $paginationButtom = clone $paginationTop;

865         $dataProvider =

new CArrayDataProvider($rawData, array(

866             'keyField'=>false,

867         ));

868         $this->render('applicantListMore', array(

869             'dataProvider'=>$dataProvider,

870             'paginationTop'=>$paginationTop,

871             'totalItemCount'=>sizeof($rawData),

872             'paginationButtom'=>$paginationButtom,

873         ));

如果需要展示的数据主题并不在一个数据表中，而是我们用Coreseek得到的一个数组，或者就是一个普通的数组

如何用数组数据来展现 GridView视图呢？

首先可以去看下$dataProvider =

new CArrayDataProvider($rawData, array(

的数据结构

object(CArrayDataProvider)#37 (10) {

["keyField"]=>

bool(false)

["rawData"]=>
array(24) {
    [0]=>
    array(2) {
      ["provinceId"]=>
      string(2) "11"
      ["provinceName"]=>
      string(9) "江苏省"
    }
……
……
    [23]=>
    array(2) {
      ["provinceId"]=>
      string(2) "15"
      ["provinceName"]=>
      string(9) "江西省"
    }
}

["_id":"CDataProvider":private]=>

NULL

["_data":"CDataProvider":private]=>

NULL

["_keys":"CDataProvider":private]=>

NULL

["_totalItemCount":"CDataProvider":private]=>

NULL

["_sort":"CDataProvider":private]=>

NULL

["_pagination":"CDataProvider":private]=>

NULL

["_e":"CComponent":private]=>

NULL

["_m":"CComponent":private]=>

NULL

}

好，那我们想要的结果是最后能够

$dataProvider = new CArrayDataProvider($IDARRAY, array(

那就来构建这个数组

734         $IDARRAY = array();

735         $total =0;

736         $totalItemCount = 0;

737         if($result['total'])

738         {

739             foreach($result['matches'] AS $k=>$v)

740             {

741                 $IDARRAY[] = array('site_name'=>$v['attrs']['site_name'],'count'=>$v['attrs']['@count']);

742                 $total+= $v['attrs']['@count'];

743             }

744             $totalItemCount = $result['total'];

745             $this->sourceMoreIDARRAY=$IDARRAY;

746             $this->sourceMoreNum=$total;

747         }

748

749         $paginationTop = new CPagination($totalItemCount);

750         $paginationTop->pageVar = 'page';

751         $paginationTop->pageSize= 10;

752         $paginationButtom = clone $paginationTop;

753
$dataProvider = new CArrayDataProvider($IDARRAY, array(

754 'keyField'=>false,

755 ));

756

757 $this->render('sourceListMore', array(

758 'dataProvider'=>$dataProvider,

759 'paginationTop'=>$paginationTop,

760 'totalItemCount'=>$totalItemCount,

761 'paginationButtom'=>$paginationButtom,

762 ));

来看下

$dataProvider = new CArrayDataProvider($IDARRAY, array(

object(CArrayDataProvider)#37 (10) {

["keyField"]=>

bool(false)

["rawData"]=>

array(456) {

[0]=>

array(2) {

["site_name"]=>

string(0) ""

["count"]=>

int(3046)

}

[1]=>

array(2) {

["site_name"]=>

string(9) "易车网"

["count"]=>

int(904)

}

[455]=>

array(2) {

["site_name"]=>

string(9) "科技讯"

["count"]=>

int(1)

}

["_id":"CDataProvider":private]=>

NULL

["_data":"CDataProvider":private]=>

NULL

["_keys":"CDataProvider":private]=>

NULL

["_totalItemCount":"CDataProvider":private]=>

NULL

["_sort":"CDataProvider":private]=>

NULL

["_pagination":"CDataProvider":private]=>

NULL

["_e":"CComponent":private]=>

NULL

["_m":"CComponent":private]=>

NULL

}

OK ，成功，其实用着样的方法，比用SQL 是不是要方便很多？

但是应该适用于，GridView中 column没几个的情况。

如果有很多Column，一般都是某个数据表的数据要展示，当然就用CActiveRecord

$rawData= model_applicant::model()->findAllBySql($sql,array('kId'=>$KDValue));
