Yii2: Conditional Validator always returns required
提问by Pawan
I am trying to use Yii2's conditional validator as given in the guide like:
我正在尝试使用指南中给出的 Yii2 的条件验证器，例如：
Model code
型号代码
public function rules()
{
// $discharged = function($model) { return $this->discharged == 1; };
return [
[[ 'admission_date','discharge_date', 'doctor_appointment_date', 'operation_date'], 'safe'],
[[ 'package','tpa_name', 'discharged', 'bed_type', 'room_category', 'ref_doctor', 'consultant_doctor', 'operation_name'], 'integer'],
[['advance_amount', 'operation_charges'], 'number'],
[['patient_name', 'ref_doctor_other'], 'string', 'max' => 50],
[['general_regn_no', 'ipd_patient_id'], 'string', 'max' => 20],
[['admission_date', 'discharge_date', 'doctor_appointment_date', 'operation_date'],'default','value'=>null],
['ipd_patient_id', 'unique'],
[['bed_type','admission_date','room_category'],'required'],
['discharge_date', 'required', 'when' => function($model) {
return $model->discharged == 1;
}],
];
}
and in my Controller like:
在我的控制器中，例如：
public function actionCreate()
{
$model = new PatientDetail();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
But whether I select or not the discharged field which is a checkbox field, the discharge date alwasys returns as required.
但是无论我是否选择了复选框字段的出院字段，出院日期总是按要求返回。
What I am doing wrong here?
我在这里做错了什么？

It seems that by default Yii2 will do validation in BOTHServer side and Client side. Check the example in Conditional Validationpart of Yii2 doc:
似乎默认Yii2将做验证BOTH服务器端和客户端。检查Yii2 docConditional Validation部分中的示例：
['state', 'required', 'when' => function ($model) {
return $model->country == 'USA';
}, 'whenClient' => "function (attribute, value) {
return $('#country').val() == 'USA';
}"],
you also need a 'whenClient'code, or as @Alexandr Bordun said, to disable the client validation by 'enableClientValidation' => false.
您还需要一个'whenClient'代码，或者如@Alexandr Bordun 所说，通过'enableClientValidation' => false.

Try to add enableClientValidationparameter as the following:
尝试添加enableClientValidation参数如下：
['discharge_date', 'required', 'when' => function($model) {
return $model->discharged == 1;
}, 'enableClientValidation' => false]

['package_id_fk', 'required', 'when' => function($model) {return $model->type == 'PACKAGE';}, 'enableClientValidation' => false],
It works for me.
这个对我有用。
回答by rinaldo
This only worked for me when using the model name (client validation).
这仅在使用模型名称（客户端验证）时对我有用。
['state', 'required', 'when' => function ($model) {
return $model->country == 'USA';
}, 'whenClient' => "function (attribute, value) {
return $('#MODELNAMEHERE-country').val() == 'USA';
}"]回答by Bloodhound
i had the similar requirement i solved it using the following code
我有类似的要求，我使用以下代码解决了它
['discharge_date', 'required', 'whenClient' => function($model) {
return $model->discharged == 1;
}, 'enableClientValidation' => false]
