Question

我有一张桌子： id |名字|值|

1 |约翰| {＆＃34; data1＆＃34;：{＆＃34; key1＆＃34;：＆＃34; abs＆＃34;，＆＃34; key2＆＃34;：＆＃34; qwe＆＃34;}，＆＃ 34; DATA2＆＃34; {＆＃34; KEY1＆＃34;：＆＃34; ASD＆＃34;＆＃34; KEY2＆＃34;：＆＃34;物镜＆＃34;}}

在每一行中，json的长度不同。我需要创建gridView，如：

id |名字| abs | asd | ...

1 |约翰| qwe | obj | ...

我的代码SqlDataProvider：

#!/bin/bash

. ./tobeincluded1   #using the . to include a file
source ./tobeincluded2 #using the source command to include a file

echo "x : $x"
echo "y : $y"

和GridView：

$count = Yii::$app->db->createCommand('
            SELECT COUNT(id) FROM statistics', [':status' => 0])-     >queryScalar();
        $dataProvider = new SqlDataProvider([
            'sql' => 'SELECT id, name, value

                    FROM 
                    statistics',

            'totalCount' => $count,
            'key'        => 'id',
        ]);

    return $this->render('statistics',
    [   
        'dataProvider'      => $dataProvider,

    ]);

当我添加专栏＆＃39; vlues＆＃39;结果就像：

1 |约翰| {＆＃34; data1＆＃34;：{＆＃34; key1＆＃34;：＆＃34; abs＆＃34;，＆＃34; key2＆＃34;：＆＃34; qwe＆＃34;}，＆＃ 34; DATA2＆＃34; {＆＃34; KEY1＆＃34;：＆＃34; ASD＆＃34;＆＃34; KEY2＆＃34;：＆＃34;物镜＆＃34;}}

请帮忙！

我认为您可以像这样添加值列

   'columns' => [
        'id',
        'name',
        [
           'attribute' => 'data1',
           'value' => function($model){
              return (json_decode($model->value)->data1);
        }
       ],
    ],

jii列到yii2中的gridview
