Yii2 ArrayHelper::map left join select - php

Question

I have users, orders and plans. When client buy plan, data is save in orders , plans are in account_plan and the information for user is in table users. In table orders is when the plan start and when it is expired. I use for Select2 ArrayHelper, but do not show the column
here is a query
$masAcc[0] = Yii::t('app', 'Choose plan');
$masAcc['----------------'] =
ArrayHelper::map(
\backend\models\Orders::find()
->select('orders.*,account_planLang.name as name')
->leftJoin('orders_props','`orders_props`.`order_id`= `orders`.`id`')
->leftJoin('account_plan','`orders_props`.`product_id`=`account_plan`.`id`')
->leftJoin('account_planLang','account_plan.id=account_planLang.plan_id')
->where('`orders`.`dt_end`<CURDATE() + INTERVAL 5 DAY AND `orders`.`dt_end`<CURDATE()')
->all(), 'id', 'name');
but the error is :
Getting unknown property: backend\models\Orders::name
here is Select2:
$form->field($model, 'account')->widget(Select2::classname(), [
'model' => $model,
'theme' => 'bootstrap',
'options' => [
'placeholder' => Yii::t('app', 'app.choose'),
'class' => 'form-control select2'
],
'data' => $masAcc,
'pluginOptions' => [
'allowClear' => true,
],
]);
}

Answer 1

That is because your query returns list of Orders models, which does not have name column, so it cannot represent result of this query. You need to use asArray() when you want to query field that is not available in model:
ArrayHelper::map(
\backend\models\Orders::find()
->select('orders.*,account_planLang.name as name')
->leftJoin('orders_props','`orders_props`.`order_id`= `orders`.`id`')
->leftJoin('account_plan','`orders_props`.`product_id`=`account_plan`.`id`')
->leftJoin('account_planLang','account_plan.id=account_planLang.plan_id')
->where('`orders`.`dt_end`<CURDATE() + INTERVAL 5 DAY AND `orders`.`dt_end`<CURDATE()')
->asArray() // <- this
->all(),
'id',
'name'
);
Or add name field to your model:
class Orders extends ActiveRecord {
public $name;
// ...
}

I guess there is no need to use ArrayHepler::map(). Try this way:
Orders::find()
->select('account_planLang.name as name, table_name.id as id')
->leftJoin('orders_props','`orders_props`.`order_id`= `orders`.`id`')
->leftJoin('account_plan','`orders_props`.`product_id`=`account_plan`.`id`')
->leftJoin('account_planLang','account_plan.id=account_planLang.plan_id')
->where('`orders`.`dt_end`<CURDATE() + INTERVAL 5 DAY AND `orders`.`dt_end`<CURDATE()')
->indexBy('id')
->column();
