Question

我正在尝试使用kartik gridview并出现以下错误。 -

<?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => $gridColumns,
        'showPageSummary' => true,
        'columns' => [
            ['class' => 'kartik\grid\SerialColumn'],
            [
                'attribute'=>'s_period',
                'filter'=>ArrayHelper::map(Salary::find()->asArray()->all(), 's_period', 's_period'),
            ],
            's_empid',
            's_empname',
            [
                'attribute'=>'s_epf',
                'pageSummary'=>true
            ],


            //['class' => 'yii\grid\ActionColumn'],
        ],
    ]); ?>

我已经检查过了 - Yii2: Kartik Gridview sum of a column in footer。但是我的代码中没有找到问题。

index.php代码 -

import UIKit

class FirstViewController: UIViewController {

    @IBOutlet weak var siteNameLabel: UILabel!


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        var siteName = ""
        let requestURL: NSURL = NSURL(string: "http://wheretogo.com.mx/backends/service.php")!
        let urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: requestURL)
        let session = NSURLSession.sharedSession()
        let task = session.dataTaskWithRequest(urlRequest) {
            (data, response, error) -> Void in

            let httpResponse = response as! NSHTTPURLResponse
            let statusCode = httpResponse.statusCode

            if (statusCode == 200) {
                //print("Everyone is fine, file downloaded successfully.")

                do{

                    let json = try NSJSONSerialization.JSONObjectWithData(data!, options:.AllowFragments)

                    if let appInfo = json["appInfo"] as? [[String: AnyObject]] {
                        siteName = appInfo[0]["siteName"] as! String
                        self.siteNameLabel.text = siteName

                    }

                }catch {
                    print("Error with Json: \(error)")
                } 
            }
        }

        task.resume()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

如果手动分配列，则不需要变量列规范，因此将其删除

<?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        //'columns' => $gridColumns,
        'showPageSummary' => true,
        'columns' => [
            ['class' => 'kartik\grid\SerialColumn'],
            [
                'attribute'=>'s_period',
                'filter'=>ArrayHelper::map(Salary::find()->asArray()->all(), 's_period', 's_period'),
            ],
            's_empid',
            's_empname',
            [
                'attribute'=>'s_epf',
                'pageSummary'=>true
            ],


            //['class' => 'yii\grid\ActionColumn'],
        ],
    ]); ?>

未定义的变量：karik gridview中的gridColumns：yii2
