我在下拉列表中添加动态表单字段。两种类型的字段都来自不同的模型，并在不同的表中转到数据库。我已经在模型中定义了验证规则。
但验证工作不正常。我的代码如下：
型号：
<?php
namespace common\models;
use Yii;
/**
* This is the model class for 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']);
}
}
控制器：
<?php

/**

public function actionView($id)
{
return $this->render('view', [
'model' => $this->findModel($id),

}
/**

}

protected function findModel($id)
{
if (($model = MembershipFeatures::findOne($id)) !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
}
表格：
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use yii\widgets\Pjax;
use yii\helpers\Url;
/* @var $this yii\web\View */
/* @var $model common\models\MembershipFeatures */
/* @var $form yii\widgets\ActiveForm */
?>
<div class="membership-features-form">
<?php $form = ActiveForm::begin([
'enableAjaxValidation' => true,
'enableClientValidation'=>true,
'validateOnSubmit'=>true,
'options' => ['data-pjax'=>true]]); ?>
<?= $form->errorSummary($model); ?>
<?= $form->field($model, 'title')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'type')->dropDownList(['boolean'=>'Boolean','value'=>'Value'],
[
'onchange'=>'
$.pjax.reload({
url: "'.Url::to(['create']).'?type="+$(this).val(),
container: "#pjax-memfeature-form",
timeout: 1000,
});
',
'class'=>'form-control',
'prompt' => 'Select Type Of Value'
]) ?>
<?php Pjax::begin(['id'=>'pjax-memfeature-form','enablePushState'=>false]); ?>
<?php
if($model->type==='boolean'){
foreach ($membershipPlan as $key => $value) {
echo $form->field($model, "value[$key]")->checkbox(array(
'label'=>"$value",
'labelOptions'=>array('style'=>'padding:5px;'),
));
}
}
if($model->type==='value'){
foreach ($membershipPlan as $key => $value) {
echo $form->field($model, "value[$key]")->textInput()->label("$value");
}
}
?>
<?php Pjax::end(); ?>
<?= $form->field($model, 'is_new')->dropDownList(['0'=>'No','1'=>'Yes']) ?>
<?= $form->field($model, 'status')->dropDownList(['1'=>'Active','0'=>'Inactive']) ?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? Yii::t('app', 'Create') : Yii::t('app', 'Update'), ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
<?= Html::a(Yii::t('app', 'Cancel'), ['/membership-features/'], ['class' => 'btn btn-danger']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
我想验证我的值字段，当我使用Pjax更改类型下拉列表时，该字段会动态添加。 请指导我验证动态添加的表单字段的正确方法。

它已经过了一个月，所以猜测这个问题已经解决了，但是对于像我这样的人来说，寻找同样的东西以及为了节省必须通过框架找到答案的参考或者尝试类似的东西：
...
use yii\helpers\Json;
...
<?php foreach ($form->attributes as $attribute) {
$attribute = Json::htmlEncode($attribute);
$this->registerJs("jQuery('form').yiiActiveForm('add', $attribute);");
} ?>
<?php Pjax::end(); ?>
...
对于clientValidation进行了测试而没有上述问题，所以已经破解了我的解决方案，希望能够回答上述问题。

简单
你应该试试这个
<?php
$this->registerJs('
jQuery("#w0").yiiActiveForm("add",{
"id": "customer-name",
"name": "name",
"container": ".field-customer-name",
"input": "#customer-name",
"error": ".help-block.help-block-error",
"validate": function(attribute, value, messages, deferred, $form) {
yii.validation.required(value, messages, {
"message": "Name be blank bug."
});
yii.validation.string(value, messages, {
"message": "Name must be a string.",
"max": 255,
"tooLong": "Name should contain at most 255 characters.",
"skipOnEmpty": 1
});
}
});
');
?>
更改
w0 加入您的表单ID
“id”：“customer-name”到您的输入字段ID中
“容器”：“。field-customer-name”进入输入字段div容器 类

这对我来说没有用，我必须为我的js添加这些addrow和deleterow函数。我ajax off每次都得到一个新行，然后在最后一行之后将它注入DOM。
//为所述元素添加验证（没有这个val.validate但我有一个验证而不是表达式错误）data是来自我的ajax控制器动作的db模型的json对象。
$.each(data.attributes, function(key, val) {
val = $.parseJSON(val);
// The validate method is kept in expression so turn it back into a closure.
val.validate = eval("var f = function(){ return "+val.validate.expression+";}; f() ;") ;
$('#dal-add-form').yiiActiveForm('add', val);
});
然后删除验证：
$.each($(this).parents('.dal-row').find('input, textarea, select'), function() {
$('#form').yiiActiveForm('remove', $(this).attr('id'));
});
