i adding dynamic form fields onchange of dropdown. both types of fields coming different models , go database in different tables. have defined validation rules in models.
but validation not working properly. code follows:
model :
<?php namespace common\models; use yii; /** * model class table "{{%membership_features}}". * * @property integer $id * @property string $title * @property string $type * @property integer $is_new * @property integer $status * @property integer $is_deleted * @property string $created_date * @property string $modified_date * * @property membershipfeaturesvalue[] $membershipfeaturesvalues */ class membershipfeatures extends \yii\db\activerecord { /** * @inheritdoc */ public $value=[]; public static function tablename() { return '{{%membership_features}}'; } /** * @inheritdoc */ public function rules() { return [ [['title', 'type', 'value','is_new', 'status'], 'required'], ['value', 'each', 'rule' => ['integer']], ['value', 'each', 'rule' => ['required']], [['is_new', 'status', 'value','is_deleted'], 'integer'], [['created_date', 'modified_date'], 'safe'], [['title', 'type'], 'string', 'max' => 255] ]; } /** * @inheritdoc */ public function attributelabels() { return [ 'id' => yii::t('app', 'id'), 'title' => yii::t('app', 'title'), 'type' => yii::t('app', 'is boolean or value'), 'is_new' => yii::t('app', 'is new'), 'status' => yii::t('app', 'status'), 'is_deleted' => yii::t('app', 'is deleted'), 'created_date' => yii::t('app', 'created date'), 'modified_date' => yii::t('app', 'modified date'), ]; } /** * @return \yii\db\activequery */ public function getmembershipfeaturesvalues() { return $this->hasmany(membershipfeaturesvalue::classname(), ['feature_id' => 'id']); } } controller :

its been month guessing has been solved reference others me looking same , save having step thru framework find answer perhaps try like:
... use yii\helpers\json; ... <?php foreach ($form->attributes $attribute) { $attribute = json::htmlencode($attribute); $this->registerjs("jquery('form').yiiactiveform('add', $attribute);"); } ?> <?php pjax::end(); ?> ... tested regards clientvalidation , not above question have hacked solution answer above question.
