Question

我有三个下降日，月和年。当我申请所需条件时yii2验证显示所有三个字段的个别错误。但我想要三个字段的单个错误消息，如“dob is required”。

查看文件：

<?= $form->field($model, "month")->dropDownList([], ['class'=>'form-control day'])->label(false);?>
<?= $form->field($model, "day")->dropDownList([], ['class'=>'form-control day'])->label(false);?>
<?= $form->field($model, "year")->dropDownList([], ['class'=>'form-control year'])->label(false);?>

模特：

public $day;    
public $month;
public $year;

[['month','day','year'], 'required', 'when' => function ($model) {
    return (($model->month == "") || ($model->day == "") || ($model->year == ""));
    }, 
    'whenClient' => "function (attribute, value) {
    return ($('#user-month').val() == '' || $('#user-day').val() == '' || $('#user-year').val() == '');
    }",'on'=>'profile'
]

此代码单独显示所有三个下拉列表的错误消息。但是我想要dob的单个错误消息：例如“dob is required”。

Answer 1

试试这个：

将此代码写入模型：

public function rules()
 {
     return [
         [['month','day','year',],'required','on'=>['create','update'],'message' => 'Please enter DOB.'],
       ];
 }

将此代码写入控制器中的操作，并在其中调用视图：

 $model = new YourModelName();
 $model->scenario = "create";

示例：

 $model = new User();
 $model->scenario = "create";

也许你sholud做更像的事情：

['month', 'validationFunction', 'skipOnEmpty' => false]
...
public function validationFunction($attribute, $params) {
    if( !$this->hasErrors() ) {
        if (!$this->month || !$this->day || !$this->year) {
            $this->addError($attribute, 'dob is required');
        }
    }    
}
