Question

我有一个表单numpy 其中有2个字段Message和message

我希望验证器根据需要验证其中一个字段

这是我到目前为止所做的事情，但它不起作用

file

以下是我的表格代码

public function rules()
{
    return [
        [['sender_id', 'receiver_id'], 'integer'],
        [['message'], 'string'],
        [['message','file'],'my_required'],
        [['is_delivered', 'is_notified', 'is_deleted', 'is_group'], 'boolean'],
        [['created_date', 'updated_date'], 'safe'],
        [['image'], 'string', 'max' => 500],
        [['file'], 'file', 'extensions'=>'jpg, gif, png, pdf'],
    ];
}

public function my_required($attribute_name, $params)
{
    if (empty($this->file)
        && empty($this->message)
    ) {
        $this->addError($attribute_name, Yii::t('user', 'At least 1 of the field must be filled up properly'));

        return false;
    }

    return true;
}

我也尝试使用它，但它也不起作用

<div class="row">
    <p>
        <?php $form = ActiveForm::begin(['options'=>['enctype'=>'multipart/form-data','id' => 'message-form']]); ?>

    <div class="form-group col-xs-3 col-lg-3">
        <?= $form->field($model, 'message')->textarea(['rows' => 6]) ?>
    </div>
    <div class="form-group col-xs-3 col-lg-3">
        <?= $form->field($model, 'file')->fileInput() ?>
        <?= $form->field($model, 'keys')->hiddenInput()->label(false); ?>

        <div class="form-group">
            <?= Html::submitButton('Send',['class' => 'btn btn-danger','data-placement'=>'right','id'=>'sendMessage']) ?>
        </div>
    </div>
    <?php ActiveForm::end(); ?>
    </p>
</div>

我也尝试过像这样的内联验证

public function rules()
{
    return [
        [['sender_id', 'receiver_id'], 'integer'],
        [['message'], 'string'],
        [['is_delivered', 'is_notified', 'is_deleted', 'is_group'], 'boolean'],
        [['created_date', 'updated_date'], 'safe'],
        [['image'], 'string', 'max' => 500],
        [['file'], 'file', 'extensions'=>'jpg, gif, png, pdf'],
        ['file', 'required', 'when' => function($model) {
            return empty($model->message);
        }],
    ];
}

但这也没有成功......

Answer 1

以下对我来说非常合适：

            ['clientGroupId', 'required', 'when' => function($model) {
                return empty($model->clientId);
            }, 'message' => 'Client group or client selection is required'],

要求在Yii2 ActiveForm中提交任何一个
