YII2：添加动态表单域及其验证 [英] YII2 : Add Dynamic form fields and their validations
本文介绍了YII2：添加动态表单域及其验证的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在下拉列表中添加动态表单域。这两种类型的字段来自不同的模型，并转到不同表中的数据库。我已经在模型中定义了验证规则。
I am adding dynamic form fields onChange of dropdown. Both types of fields are coming from different models and go to the database in different tables. I have already defined validation rules in models.
但验证无法正常工作。我的代码如下：
But validation are not working properly. My code is as follows:
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'),

形式：
<?php

use yii\widgets\ActiveForm;
use yii\widgets\Pjax;

/* @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' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
<?= Html::a(Yii::t('app', 'Cancel'), ['/membership-features/'], ['class' => 'btn btn-danger']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
我想验证我在更改时动态添加的值字段使用Pjax的类型下拉菜单。
请指导我正确的验证动态添加表单字段的方法。
I want to validate my value field which is dynamically added when I change the type dropdown using Pjax. Please guide me a correct method for validating dynamically added form fields.
推荐答案
已经有一个月了，这个猜测已经解决了，但为了参考，像我这样的人寻找相同的东西，通过框架来找到答案可能会尝试像：
Its been a month so guessing this has been solved but for reference for others like me looking for the same and to save having to step thru the framework to find the answer perhaps try something like:
...
use yii\helpers\Json;
...
<?php foreach ($form->attributes as $attribute) {
$attribute = Json::htmlEncode($attribute);
$this->registerJs("jQuery('form').yiiActiveForm('add', $attribute);");
} ?>
<?php Pjax::end(); ?>
...
关于clientValidation而不是上述问题进行了测试，所以黑客入侵解决方案希望能回答上述问题。
Tested with regards to clientValidation and not with above question so have hacked my solution to hopefully answer above question.
