我正在尝试在Yii2中为DynamicFormWidget小部件添加自定义验证。有一个DynamicFormWidget小部件＆＃39;百分比＆＃39;以及所有＆＃39;百分比＆＃39;的总和动态创建的值应为100.我添加了验证规则
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'],
];
}
但是没有显示错误。代码在function checkPercentageTotal()
这是我的视图文件中的代码：

CategoryModel中的代码是
<?php
namespace backend\models;
use Yii;
/**

*
* @property int $id
* @property string $survey_id
*/
class Category extends \yii\db\ActiveRecord

* @inheritdoc
*/
public static function tableName()
{
return 'category';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['survey_id', 'percentage'], 'required'],
[['survey_id' ], 'string', 'max' => 250],
[['percentage'] ,'checkPercentageTotal'],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'id' => Yii::t('app', 'ID'),
'survey_id' => Yii::t('app', 'Survey ID'),
'percentage' => Yii::t('app', 'Percent'),
];
}
public function getQuestions()
{
return $this->hasMany(Question::className(), ['cat_id' => 'id']);
}
public function checkPercentageTotal($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;
}
}
}
和SurveyModel的代码是
<?php
namespace backend\models;
use Yii;
/**

*
* @property int $id
* @property string $form_id
* @property string $dept

*/
class Survey extends \yii\db\ActiveRecord
{
/**
* @inheritdoc
*/
/**===============================
* floated variable for survey form
*/
/**
* end here =====================
*/
public static function tableName()
{
return 'survey';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['form_id', 'title', 'abstract', 'ledger','date_created'], 'required'],
[['form_id'], 'string', 'max' => 1250],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'id' => Yii::t('app', 'ID'),
'form_id' => Yii::t('app', 'Form ID'),
'title' => Yii::t('app', 'Title'),
'abstract' => Yii::t('app', 'Abstract'),
'ledger' => Yii::t('app', 'Ledger'),
'date_created' =>Yii::t('app', 'Date Created'),
'depart' =>Yii::t('app', 'Department'),
];
}
}
创建活动控制器的代码是
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
答案 0 :(得分：1)
我想这是主要问题：
$valid[] = $modelSurvey->validate();
$valid[] = Model::validateMultiple($modelsCategory) && $valid;
// ...
if ($valid) {
即使您的所有验证都返回false，您也会获得false个数组，这些数组将被视为true（非空数组=== true）。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，你的代码非常混乱，需要一些严肃的重构。您不应直接在模型内部访问GET或POST数据，此操作和验证过于复杂。
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验证程序并不真正适合Category模型 - 现在您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模型上完成，只需执行一次。
