Yii2 中 DynamicFormWidget 的自定义验证不起作用

Question

我正在尝试为 Yii2 中的 DynamicFormWidget 小部件添加自定义验证。有一个 DynamicFormWidget 小部件 'percentage'，动态创建的所有 'percentage' 值的总和应该是 100。我添加了一个验证规则

public function checkPercentageTotal($attribute, $params){
        foreach (Yii::$app->request->post()['Category'] as $percentage){
        $percentage_values[]=$percentage['percentage'];
        }
        if( array_sum($percentage_values)<>100){
              $this->addError($attribute, 'Total percentage should be 100');return false;
        }
    }

并添加了

public function rules()
    {
        return [

            [['percentage'] ,'checkPercentageTotal'],
        ];
    }

但未显示 error.The 代码正在 function checkPercentageTotal()

中执行

这是我的视图文件中的代码：

<?php

namespace backend\models;

use Yii;

            'depart' =>Yii::t('app', 'Department'),


        ];
    }


}

创建动作控制器的代码是

public function actionCreate()
    {
        $modelSurvey = new Survey;
        $modelsCategory = [new Category];
        $modelsQuestion = [[new Question]];

        if ($modelSurvey->load(Yii::$app->request->post())) {

            foreach($_POST['depart'] as $departindex => $departvalue){
                    $department[]=$departvalue;

            }
            $dep=implode(',',$department);

            $modelsCategory = Model::createMultiple(Category::classname());
            Model::loadMultiple($modelsCategory, Yii::$app->request->post());

            // validate survey and category models
            $valid[] = $modelSurvey->validate();


            $valid[] = Model::validateMultiple($modelsCategory) && $valid;

            if (isset($_POST['Question'][0][0])) {
                foreach ($_POST['Question'] as $indexCategory => $questions) {
                    foreach ($questions as $indexQuestion => $question) {
                        $data['Question'] = $question;
                        $modelQuestion = new Question;
                        $modelQuestion->load($data);
                        $modelsQuestion[$indexCategory][$indexQuestion] = $modelQuestion;
                        $valid[] = $modelQuestion->validate();
                    }
                }
            }

            if ($valid) {
                $transaction = Yii::$app->db->beginTransaction();
                try {

                    $today = date("Y-m-d H:i:s");
                    $modelSurvey->date_created=$today;
                    $modelSurvey->depart=$dep;
                    $modelSurvey->type_id=$_POST['type_id'];
                    if ($flag = $modelSurvey->save(false)) {
                        foreach ($modelsCategory as $indexCategory => $modelCategory) {

                            if ($flag === false) {
                                break;
                            }

                            $modelCategory->survey_id = $modelSurvey->id;

                            if (!($flag = $modelCategory->save(false))) {
                                break;
                            }

                            if (isset($modelsQuestion[$indexCategory]) && is_array($modelsQuestion[$indexCategory])) {
                                foreach ($modelsQuestion[$indexCategory] as $indexQuestion => $modelQuestion) {
                                    $modelQuestion->cat_id = $modelCategory->id;
                                    if (!($flag = $modelQuestion->save(false))) {
                                        break;
                                    }
                                }
                            }
                        }
                    }

                    if ($flag) {
                        $transaction->commit();
                        return $this->redirect(['view', 'id' => $modelSurvey->id]);
                    } else {
                        $transaction->rollBack();
                    }
                } catch (Exception $e) {
                    $transaction->rollBack();
                }
            }
        }

        return $this->render('create', [
            'modelSurvey' => $modelSurvey,
            'modelsCategory' => (empty($modelsCategory)) ? [new Category] : $modelsCategory,
            'modelsQuestion' => (empty($modelsQuestion)) ? [[new Question]] : $modelsQuestion,
        ]);
    }

我认为自定义验证规则对动态表单小部件元素没有任何影响

Answer 1

我想这是主要问题：

$valid[] = $modelSurvey->validate();
$valid[] = Model::validateMultiple($modelsCategory) && $valid;

// ...

if ($valid) {

即使你所有的验证 returns false，你也会得到 false 的数组，这将被视为 true （非空数组 == = 真）。您可以尝试使用以下内容更改此代码：

$valid = Model::validateMultiple($modelsCategory) && $valid;

但老实说，您的代码确实很乱，需要进行认真的重构。您不应该直接在模型内部访问 GET 或 POST 数据，并且此操作和验证非常复杂。

对于这种情况，您应该创建单独的 SurveyForm 并且所有验证和保存都应该在其中。 checkPercentageTotal 验证器并不真正适合 Category 模型 - 现在您正在多次执行相同的验证（分别针对每个类别）。此验证可能应该在 SurveyForm 模型中完成，仅一次。

Yii2 中 DynamicFormWidget 的自定义验证不起作用
