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));
