Question

我正在使用Yii2框架。我正在制作存储promocodes的表格。我有两个名为discount_type＆amp;的字段discount_value。 discount_type是带有期权百分比＆amp;的下拉列表量。我想验证discount_value字段取决于用户对discount_type下拉菜单的选择。如果用户选择百分比，则discount_value字段的最大值验证为100。

_form.php是：

<div class="promocode-form">
    <div class="row">
        <div class="col-md-12">
            <div class="col-lg-8">
                <?php $form = ActiveForm::begin(); ?>

                <?= $form->field($model, 'promo_name') ?>

                <?php
                    $a= ['percentage' => 'Percentage', 'amount' => 'Amount'];
                    echo $form->field($model, 'discount_type')->dropDownList($a,['prompt'=>'Select Option']);
                ?>

                <?= $form->field($model, 'promocode_value')->textInput(['type'=>'number']) ?>

                <?= $form->field($model, 'promocode_limit')->textInput(['type'=>'number']) ?>

                <?= $form->field($model, 'start_date')->textInput(['class' => 'form-control','placeholder'=>'Start Date','id'=>'dt1','readonly'=>"readonly",'value'=>$astart]) ?>

                <?= $form->field($model, 'end_date')->textInput(['class' => 'form-control','placeholder'=>'End Date','id'=>'dt2','readonly'=>"readonly",'value'=>$aend]) ?>

                <?= $form->field($model, 'status')->dropDownList(['1'=>'Active','0'=>'Deactive'],['prompt'=>'Select Option']) ?>

                <div class="form-group">
                    <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
                </div>

                <?php ActiveForm::end(); ?>
            </div>
        </div>
    </div>
</div>

模型中的规则是：

public function rules()
{
    return [
        [['adminid', 'promo_name', 'discount_type', 'promocode_value', 'promocode_limit', 'start_date', 'end_date', 'status', 'created_at', 'updated_at'], 'safe'],
        [['promo_name', 'discount_type', 'promocode_value', 'promocode_limit', 'start_date', 'end_date', 'status'], 'required'],
        ['promocode_value', 'number', 'min' => 0],
        [['promocode_value'], 'max' => '100','whenClient' => 'function (attribute, value) {return $("#discount_type").val() == "percentage";}'],
    ];
}

出现此错误：

PHP User Error – yii\base\ErrorException

Exception (Invalid Configuration) 'yii\base\InvalidConfigException' with message 'Invalid validation rule: a rule must specify both attribute names and validator type.'

我认为问题出现在'max'=>'100'当我使用'required'代替它时，它运行正常。但我想使用＆＃39; max＆＃39;验证。请帮助解决我的问题。

提前致谢！

您没有在您的规则中放置验证器的名称。而不是：

[['promocode_value'], 'max' => '100','whenClient' => 'function (attribute, value) {return $("#discount_type").val() == "percentage";}']

应该是这样的：

[['promocode_value'], 'number', 'max' => '100','whenClient' => 'function (attribute, value) {return $("#discount_type").val() == "percentage";}']

＆＃39; whenClient＆＃39;没有使用＆＃39; max＆＃39;验证
