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']);
    }
}

    <?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.
