php – YII2：添加动态表单字段及其验证
作者：互联网
我正在添加动态表单字段onChange of dropdown.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
namespace backend\controllers;
use Yii;
use common\models\MembershipFeatures;

'delete' => ['post'],

];
}
/**

*/
public function actionIndex()
{
$searchModel = new MembershipFeaturesSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [

]);
}
/**

* @param integer $id
* @return mixed
*/
public function actionView($id)
{
return $this->render('view', [
'model' => $this->findModel($id),
]);
}
/**

* If creation is successful, the browser will be redirected to the 'view' page.
* @return mixed
*/
public function actionCreate()
{
$model = new MembershipFeatures();
$membershipPlan = \common\models\MembershipPlan::allPlans();

}
}
return $this->redirect(['index']);
}
return $this->render('create', [

}
/**

*/
public function actionUpdate($id)

public function actionDelete($id)
{
Helper::partialDelete('MembershipFeatures',$id);
return $this->redirect(['index']);
}
/**

*/
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' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
<?= Html::a(Yii::t('app', 'Cancel'), ['/membership-features/'], ['class' => 'btn btn-danger']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
我想验证我在使用Pjax更改类型下拉列表时动态添加的值字段.
请指导我验证动态添加的表单字段的正确方法.
解决方法:
它已经过了一个月,所以猜测这个问题已经解决了,但是对于像我这样的其他人来说,寻找同样的东西以及为了节省必须通过框架来寻找答案,或者尝试类似的东西：
...
use yii\helpers\Json;
...
<?php foreach ($form->attributes as $attribute) {
$attribute = Json::htmlEncode($attribute);
$this->registerJs("jQuery('form').yiiActiveForm('add', $attribute);");
} ?>
<?php Pjax::end(); ?>
...
测试了clientValidation而不是上面的问题所以已经破解了我的解决方案,希望能回答上述问题.
