How to save embed document in Yii MongoDB Suite - php

Question

I have 2 classes "users" and "userName"
class users extends EMongoDocument {
public $name;
public $address;
public static function model($className = __CLASS__) {
return parent::model($className);
}
// This method is required!
public function getCollectionName() {
return 'users';
}
public function getMongoDBComponent() {
return Yii::app()->mongodb;
}
public function behaviors() {
return array(
array(
'class' => 'ext.YiiMongoDbSuite.extra.EEmbeddedArraysBehavior',
'arrayPropertyName' => 'name', // name of property
'arrayDocClassName' => 'userName' // class name of documents in array
),
);
}
public function rules() {
return array(
array('name, address', 'required'),
array('name, address', 'length', 'max' => 255),
);
}
public function attributeLabels() {
return array(
'name' => 'Full name',
'address' => 'Address',
);
}
}
class userName extends EMongoEmbeddedDocument {
public $firstname;
public $middlename;
public $lastname;
public static function model($className = __CLASS__) {
return parent::model($className);
}
// This method is required!
public function getCollectionName() {
return 'userName';
}
public function rules() {
return array(
array('firstname, middlename,lastname', 'required'),
array('firstname, middlename,lastname', 'length', 'max' => 255),
);
}
public function attributeLabels() {
return array(
'firstname' => 'First Name',
'middlename' => 'Middle Name',
'lastname' => 'Last Name',
);
}
}
I have code:
I can't save embed document. I have an error:
mb_strlen() expects parameter 1 to be string, array given

Answer 1

You have a validation rule of max length for the name attribute. This rule uses function mb_strlen. But for some reason you've wrote $u->name[0] = new UserName(), so you name attribute becomes an array, but not a string. That's the reason.
