[英]Yii2, custom validation: clientValidateAttribute() doesn't work correctly
我有一個由ActiveForm小部件創建的表單。 用戶在那里輸入波蘭郵政編碼。 在適當的控制器中,我將輸入的數據放入DB中,例如:
$company_profile_data->postal_code = $_POST['CompanyProfiles']['postal_code'];
$company_profile_data->update();
我決定使用獨立驗證器進行郵政編碼驗證。 模型中此屬性的規則 :
public function rules() {
return [
//...some other rules...
['postal_code', 'string', 'length' => [6,6]],
['postal_code', PostalValidator::className()], //standalone validator
];
}
app / components / validators / PostalValidator類代碼 :
namespace app\components\validators;
use yii\validators\Validator;
use app\models\CompanyProfiles;
use app\models\Users;
class PostalValidator extends Validator {
public function init() {
parent::init();
}
public function validateAttribute($model, $attribute) {
if (!preg_match('/^[0-9]{2}-[0-9]{3}$/', $model->$attribute))
$model->addError($attribute, 'Wrong postal code format.');
}
public function clientValidateAttribute($model, $attribute, $view) { //want js-validation too
$message = 'Invalid status input.';
return <<<JS
if (!/^[0-9]{2}-[0-9]{3}$/.test("{$model->$attribute}")) {
messages.push("$message");
}
JS;
}
}
因此,正確代碼的示例是00-202 。
當我(在用戶角色中)輸入錯誤的值,頁面重新加載,我看到Wrong postal code format.
消息,雖然我重新定義了clientValidateAttribute
方法並編寫了JS-validation
,正如我所建議的那樣,它不允許重新加載頁面。 然后我再次按下提交按鈕:這個時間頁面沒有重新加載,我看到Invalid status input.
消息(所以,第二次按下時間JS觸發)。 但是在我輸入正確的代碼后,我仍然看到Invalid status input.
消息沒有任何反應。
那么,我的clientValidateAttribute()
方法出了什么問題? validateAttribute()
效果很好。
來自控制器的 UPDATE Snippet
public function actionProfile(){ //can't use massive assignment here, cause info from 2 (not 1) user models is needed
if (\Yii::$app->user->isGuest) {
return $this->redirect('/site/index/');
}
$is_user_admin = Users::findOne(['is_admin' => 1]);
if ($is_user_admin->id == \Yii::$app->user->id)
return $this->redirect('/admin/login/');
$is_user_blocked = Users::find()->where(['is_blocked' => 1, 'id' => \Yii::$app->user->id])->one();
if($is_user_blocked)
return $this->actionLogout();
//3 model instances to retrieve data from users && company_profiles && logo
$user_data = Users::find()->where(['id'=>\Yii::$app->user->id])->one();
$user_data->scenario = 'update';
$company_profile_data = CompanyProfiles::find()->where(['user_id'=>Yii::$app->user->id])->one();
$logo = LogoData::findOne(['user_id' => \Yii::$app->user->id]);
$logo_name = $logo->logo_name; //will be NULL, if user have never uploaded logo. In this case placeholder will be used
$upload_logo = new UploadLogo();
if (Yii::$app->request->isPost) {
$upload_logo->imageFile = UploadedFile::getInstance($upload_logo, 'imageFile');
if ($upload_logo->imageFile) { //1st part ($logo_data->imageFile) - whether user have uploaded logo
$logo_file_name = md5($user_data->id);
$is_uploaded = $upload_logo->upload($logo_file_name);
if ($is_uploaded) { //this cond is needed, cause validation for image fails (?)
//create record in 'logo_data' tbl, deleting previous
if ($logo_name) {
$logo->delete();
} else { //if upload logo first time, set val to $logo_name. Otherwise NULL val will pass to 'profile' view, and user wont see his new logo at once
$logo_name = $logo_file_name.'.'.$upload_logo->imageFile->extension;
}
$logo_data = new LogoData;
$logo_data->user_id = \Yii::$app->user->id;
$logo_data->logo_name = $logo_name;
$logo_data->save();
}
}
}
if (isset($_POST['CompanyProfiles'])){
$company_profile_data->firm_data = $_POST['CompanyProfiles']['firm_data'];
$company_profile_data->company_name = $_POST['CompanyProfiles']['company_name'];
$company_profile_data->regon = $_POST['CompanyProfiles']['regon'];
$company_profile_data->pesel = $_POST['CompanyProfiles']['pesel'];
$company_profile_data->postal_code = $_POST['CompanyProfiles']['postal_code'];
$company_profile_data->nip = $_POST['CompanyProfiles']['nip'];
$company_profile_data->country = $_POST['CompanyProfiles']['country'];
$company_profile_data->city = $_POST['CompanyProfiles']['city'];
$company_profile_data->address = $_POST['CompanyProfiles']['address'];
$company_profile_data->telephone_num = $_POST['CompanyProfiles']['telephone_num'];
$company_profile_data->email = $_POST['CompanyProfiles']['email'];
$company_profile_data->update();
}
if (isset($_POST['personal-data-button'])) {
$user_data->username = $_POST['Users']['username'];
$user_data->password_repeat = $user_data->password = md5($_POST['Users']['password']);
$user_data->update();
}
return $this->render('profile', ['user_data' => $user_data, 'company_profile_data' => $company_profile_data, 'upload_logo' => $upload_logo, 'logo_name' => $logo_name]);
}
我的不准確之處在於clientValidateAttribute()
方法。 而不是$model->$attribute
code in code snippet:
if (!/^[0-9]{2}-[0-9]{3}$/.test("{$model->$attribute}")) {
...我必須使用預定義的JS-var 值 ,導致此變化隨輸入值的變化而變化。 所以,我的新代碼是:
public function clientValidateAttribute($model, $attribute, $view) {
return <<<JS
if (!/^[0-9]{2}-[0-9]{3}$/.test(value)) {
messages.push("Wrong postal code format.");
}
JS;
}
在沒有從模型中調用任何函數之前 ,模型不會加載規則和行為。 當你調用$company_profile_data->update();
模型調用update
和validate
功能。
嘗試在$company_profile_data = CompanyProfiles::find()
之后添加此代碼:
$company_profile_data->validate();
或者只使用load
功能。 我認為這會有所幫助。
