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：

         $sql = "SELECT * FROM zhuanli_applicantCount where kId=:kId order by percentage desc";
 $rawData= model_applicant::model()->findAllBySql($sql,array('kId'=>$KDValue));
         $IDARRAY = array();
 
         $paginationTop = new CPagination(sizeof($rawData));
         $paginationTop->pageVar = 'page';
         $paginationTop->pageSize= 10;
         $paginationButtom = clone $paginationTop;
         $dataProvider = new CArrayDataProvider($rawData, array(
             'keyField'=>false,
         ));
         $this->render('applicantListMore', array(
             'dataProvider'=>$dataProvider,
             'paginationTop'=>$paginationTop,
             'totalItemCount'=>sizeof($rawData),
             'paginationButtom'=>$paginationButtom,
         ));

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

        $IDARRAY = array();
        $total =0;
        $totalItemCount = 0;
        if($result['total'])
        {
            foreach($result['matches'] AS $k=>$v)
            {
                $IDARRAY[] = array('site_name'=>$v['attrs']['site_name'],'count'=>$v['attrs']['@count']);
                $total+= $v['attrs']['@count'];
            }
            $totalItemCount = $result['total'];
            $this->sourceMoreIDARRAY=$IDARRAY;
            $this->sourceMoreNum=$total;
        } 

        $paginationTop = new CPagination($totalItemCount);
        $paginationTop->pageVar = 'page';
        $paginationTop->pageSize= 10;
        $paginationButtom = clone $paginationTop;
$dataProvider = new CArrayDataProvider($IDARRAY, array(
            'keyField'=>false,
        ));

        $this->render('sourceListMore', array(
            'dataProvider'=>$dataProvider,
            'paginationTop'=>$paginationTop,
            'totalItemCount'=>$totalItemCount,
            'paginationButtom'=>$paginationButtom,
        ));

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));
