Being trying to sort this out but going nowhere with it. I have got an array as attribute for a model and I am trying to create custom validation for some of the keys in the array as required. Or even can't figure out how the attribute labels will work? Here is my code:
MODEL
...
public $company = [
'name' => '',
'trading_name' => '',
'type' => '',
];
public function attributeLabels(){
return [
'company[name]' => 'Company Name',
];
}
public function rules(){
return [
[['company[name]','company[trading_name'], 'safe'],
[['company[name]'], 'return_check','skipOnEmpty'=> false],
];
}
public function return_check($attribute, $params){
$this->addError($attribute ,'Required ');
return false;
}
...
I have even tried to pass the whole array and check in the validator method for the keys and values but the custom validator is not even triggered.
I think you need separated model for company.
I've used custom rule functions, and they all worked. Try removing the return clause at the end of the return_check function.
Here's what has worked for me:
class Essid extends ActiveRecord {
public function rules() {
return [
['network_name', 'checkNetworkName']
]
}
public function checkNetworkName($attribute, $params){
if (!$this->hasErrors()) {
if ( !ctype_alnum($this->network_name) )
$this->addError($attribute, Yii::t('app', 'Not a valid Network Name'));
}
}
}
Hope it helps

I want to decrypt the email attribute of my model:
protected $fillable = [
'email',
'password',
'remember_token',
'status',
'name',
'lastname',
'password_changed_at',
'role',
'attempts'
];
By using this mutator with JSON Append
protected $appends = ['email'];
public function getEmailAttribute($value)
{
return $this->attributes['email'] === Crypt::decrypt($value);
}
The problem I'm facing it's that when I execute a dump and die, the response hasn't change the email attribute.
Any ideas on how i can change the response to return the email decrypted?
Thanks :)
There is no need to use appends, try below:
public function getEmailAttribute($value)
{
return Crypt::decrypt($value);
}
In model I have defined multiple scenarios:
public function rules() {
return [
[['in_quantity'], 'required','on'=>['stockIn']],
[['out_quantity'], 'required','on'=>['stockOut']],
];
}
Is it possible to use both scenario stockIn and stockOut for single model validation?
$StockModel->scenario[] = 'stockOut';
$StockModel->scenario[] = 'stockIn';
or
$StockModel->scenario = ['stockOut','stockIn'];
You can't have multiple scenarios for model. But you can have multiple scenarios for rule:
public function rules() {
return [
[['in_quantity'], 'required', 'on' => ['stockIn', 'stockOut']],
[['out_quantity'], 'required', 'on' => ['stockIn', 'stockOut']],
];
}
If you need multiple scenarios for model, it means that you're overusing scenarios feature.
Also note that it is not recommended to use too many scenarios in one model - scenarios work fine for simple cases, but more complicated cases should be handled by separate models for each scenario.
You can create multiple scenarios this way in model
class MyModel extends \yii\db\ActiveRecord {
const SCENARIO_CREATE = 'scenario_create';
const SCENARIO_UPDATE = 'scenario_update';
// get scenarios
public function scenarios()
{
return [
self::SCENARIO_CREATE => ['user_id', 'name', 'desc', 'published','date_create'],
self::SCENARIO_UPDATE => ['user_id', 'name', 'desc', 'date_update'],
];
}
public function rules()
{
[['user_id'], 'integer'],
[['name','desc'], 'string', 'max' => 70],
[['date_create', 'date_update'], 'date', 'format' => 'php:Y-m-d H:i:s'],
];
}
}
and you can use this way anywhere
public function actionIndex() {
$model = new MyModel;
$model->scenario = MyModel::SCENARIO_CREATE;
if ($model->load(\Yii::$app->request->post())){
if($model->save()){
// some operations
}
}
}
You could if you extend the rule with when for server validation:
[
['in_quantity'],
'required',
'when' => function ($model) {
return $model->scenario === 'stockIn' || $model->scenario === 'stockOut';
}
]
Also if you want to validate in the form (aka client side validation) you could also use the whenClient that expect a js function:
'whenClient' => "function (attribute, value) {
const scenario = $('#stock-scenario').val()
return scenario === 'stockIn' || scenario = 'stockOut';
}"
I have a text field that was defined as required in its model. But a view needs not be required. I try this way to remove the required attribute but it doesn't work:
<?= $form->field($model, 'city')->textInput(['required' => false]) ?>
I need to change it in a view or in its controller. But not in its model (because others view needs the required attribute.).
I know how to do it using jQuery but I prefer with PHP/Yii2.
Update (requiered by the nice help of #Muhammad Omer Aslam):
My model is called Persons.
My view is called _form.
My controller is called PersonsControllers. It has the update function:
actionUpdate($id):
public function actionUpdate($id)
{
$model = $this->findModel($id); // How to add my new scenario here?
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id_person]);
}
return $this->render('update', [
'model' => $model,
]);
}
You can use scenarios to make the field required or not for the specific view. You can assign the active fields that are required for the scenario, and those fields will be the subject to validation.
I assume the model is Profile. In below example firstname, lastname and city is required in the default scenario.
A model may be used in different scenarios, by default the scenario default is used. Let's say in your case we can declare a scenario special that will only require firstname and lastname. In your model, you will declare a constant for the scenario name, and then override the scenarios() method, key=>value pairs with the active field names being passed in form of an array to the value will be assigned.
namespace app\models;
use yii\db\ActiveRecord;
class Profile extends ActiveRecord
{
const SCENARIO_SPECIAL = 'special';
public function scenarios()
{
$scenarios = parent::scenarios();
$scenarios[self::SCENARIO_SPECIAL] = ['firstname', 'lastname'];
return $scenarios;
}
}
and then inside your controller/action for that view where you do not want the city field to be required, initialize the Profile model object as below
public function actionProfile(){
$model = new \common\models\Profile(['scenario'=> \common\models\Profile::SCENARIO_SPECIAL]);
return $this->render('profile',['model'=>$model]);
}
Now if you submit the form inside this view it will ask only for the firstname and lastname whereas in your previous forms/views if you try to submit the form it will ask you to provide the city when trying to submit, you don't have to change or add anything for the rest of the forms or the rules.
As you are trying to update the record and do not want the city to be required when updating the record, the only difference that could be is to assign the scenario like below as you are not creating a new object for the model.
$model->scenario=\common\models\Profile::SCENARIO_SPECIAL;
In the model:
const SCENARIO_MYSPECIAL = 'myspecial';
public function rules()
{
return [
[['id_person', 'city'], 'required', 'on' => self::SCENARIO_DEFAULT],
[['id_person'], 'required', 'on' => self::SCENARIO_MYSPECIAL],
];
}
In the controller:
public function actionUpdate($id)
{
$model = $this->findModel($id);
$model->scenario = 'myspecial';
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id_person]);
}
return $this->render('update', [
'model' => $model,
]);
}
go to the model and remove the attribute
public function rules()
{
return [
[['id_person', 'city'], 'required'],
[['id_person'], 'required'],
];
}
EX:
public function rules()
{
return [
[['id_person'], 'required'],
[['id_person'], 'required'],
];
}
In Yii2 framework is it possible to add a new attribute dynamically to an existing object, which is retrieved from Database?
Example
//Retrieve from $result
$result = Result::findone(1);
//Add dynamic attribute to the object say 'result'
$result->attributes = array('attempt' => 1);
If it is not possible, please suggest an alternate best method to implement it.
Finally I would be converting the result to a json object. In my application, at the behaviour code block, I have used like this:
'formats' => [
'application/json' => Response::FORMAT_JSON,
],
You can add define a public variable inside your model, that will store dynamic attributes as associative array. It'll look something like this:
class Result extends \yii\db\ActiveRecord implements Arrayable
{
public $dynamic;
// Implementation of Arrayable fields() method, for JSON
public function fields()
{
return [
'id' => 'id',
'created_at' => 'created_at',
// other attributes...
'dynamic' => 'dynamic',
];
}
...
..in your action pass some dynamic values to your model, and return everything as JSON:
public function actionJson()
{
\Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
$model = Result::findOne(1);
$model->dynamic = [
'field1' => 'value1',
'field2' => 2,
'field3' => 3.33,
];
return $model;
}
In result you will get JSON like this:
{"id":1,"created_at":1499497557,"dynamic":{"field1":"value1","field2":2,"field3":3.33}}
I have custom form where I am trying to write a custom validator, but its not firing. The model is returned as valid every time submit button is hit:
class DeactivateForm extends Model {
public $deactivate_reason;
public function rules() {
return [
[ 'deactivate_reason', 'reasonValidator' ],
];
}
public function reasonValidator( $attribute, $params ) {
$this->addError( 'deactivate_reason', 'Error !!!' );
}
public function attributeLabels() {
return [
'deactivate_reason' => 'Reason for deactivating',
];
}
}
The actual form is plain jane:
$form = ActiveForm::begin( [
'id' => 'deactivate-form'
] );
When using [ 'deactivate_reason', 'required' ] in the rules, the required rule works fine, custom rule is still ignored...
I am not sure but to forcefully run validation on empty field, add following property.
skipOnError=>false and skipOnEmpty=>false
[
['deactivate_reason', 'reasonValidator', 'skipOnError' => false,'skipOnEmpty'=>false],
]
Try this,add return like below
public function reasonValidator( $attribute, $params ) {
return $this->addError( 'deactivate_reason', 'Error !!!' );
}
