Question

我目前正在设置一个gridview，其中一个表中字段的每个结果都需要成为一个标题

不幸的是，我似乎无法找到一种方法将值设置为标题，同时还允许另一个表中的值

例如，我需要将name字段中的每个结果都作为我的cgridview

的标题

然后，每个链接到值标题的结果也会显示为此标题的值

我的猜测是，我会以某种方式将结果添加到数据提供者，循环数据提取器以获取结果以填充列并使用此函数作为gridview的结果但如果我没有严格定义列则分页

我遇到的问题是该列仍然显示为HEADER1而不是数据，而数据只是我拉的数据

public function exportSearch($event_id){

        $query = "SELECT
                    u.prefix AS  'Title', 
                    u.forename AS  'Forename', 
                    u.surname AS  'Surname', 
                    u.telephone AS 'Mobile Number',
                    u.email AS  'Email Address', 
                    ea.checkin_status_id AS 'checked in',
                    u.update_time AS  'Register Date', 
                    eg.name AS 'Event Group Registered', 
                    e.name AS  'Session Registered', 
                    u.bio AS 'User Information',
                    u.dob AS 'Date of Birth',
                    u.company AS 'Company',
                    u.company_role AS 'Company Role',
                    CONCAT(u2.forename, ' ', u2.surname) AS 'Guest of',
                    MAX(CASE WHEN uv.user_type_variables_id = 1 THEN uv.name ELSE NULL END) AS Header1,
                    MAX(CASE WHEN uv.user_type_variables_id = 1 THEN uv.value ELSE NULL END) AS Question1,
                    MAX(CASE WHEN uv.user_type_variables_id = 2 THEN uv.value ELSE NULL END) AS Question2,
                    MAX(CASE WHEN uv.user_type_variables_id = 3 THEN uv.value ELSE NULL END) AS Question3,
                    MAX(CASE WHEN uv.user_type_variables_id = 4 THEN uv.value ELSE NULL END) AS Question4,
                    MAX(CASE WHEN uv.user_type_variables_id = 5 THEN uv.value ELSE NULL END) AS Question5,
                    MAX(CASE WHEN uv.user_type_variables_id = 6 THEN uv.value ELSE NULL END) AS Question6

                    FROM tbl_event_attendees AS ea

                    LEFT JOIN tbl_user AS u ON ea.user_id = u.id
                    LEFT JOIN tbl_event AS e ON ea.event_id = e.id
                    LEFT JOIN tbl_event_groups AS eg on e.group_id = eg.id
                    LEFT JOIN tbl_user AS u2 ON ea.guest_of_user_id = u2.id
                    LEFT JOIN tbl_user_variables AS uv on u.id = uv.user_id

                    WHERE ea.event_id = {$event_id}

                    GROUP BY ea.id";




        $count=Yii::app()->db->createCommand($query)->queryScalar();
        return $sqlDataprovider = new CSqlDataProvider($query, array(
                'totalItemCount'=>$count,
                'sort'=>array(
                    'attributes'=>array(
                    )
                ),
                'pagination'=>array(
                'pageSize'=>$count, //Show all records
        ),
            ));
     }

和我的观点

array(
            'header' => $data['Header1'],
            'name' => 'Header1',
            'type' => 'raw',
            'value' => $data['Question6'],
        ),

结果只是将我想要的标题输入到值中，并将AS标识符作为标题输入。

您可以使用列的标题属性

array('name'=>'yoir_column_name',
  'header'=> '$your_value_from_db_for_header',
 ),

应该是这样的事情

$this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'your_id',
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        'your_first_column' ,
        'your_second_column',
         array(
            'header'=> $data['Header1'],
            'value'=> '$data->Question6',
            'name'=> 'Question6',
        ),

字段结果为cgridview中的标题
