Yii framework: how to get id from DB, when choosing related record from DB - yii

Question

I have text edit box with Autocomplete::widget on the web page.
Autocomplete populates from DB. When I start to type and choose Autocomplete item (which is the First Name from DB, in my case) I need to get the associated id from DB. How could this get implemented?
<?php
use yii\helpers\ArrayHelper;
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use app\models\Rating;
use app\models\Teacher;
use yii\jui\AutoComplete;
use yii\web\JsExpression;
/* #var $this yii\web\View */
/* #var $model app\models\Rating */
/* #var $form ActiveForm */
$data = Teacher::find()
->select(['lname as value', 'lname as label','id as id'])
->asArray()
->all();
//print_r($data[0].id);//exit;
?>
<div class="rating-input">

<?php
echo AutoComplete::widget([
'name' => 'Teacher',
'id' =>'ddd',
'clientOptions' => [
'source' => $data,
'autoFill'=>true,
'minLength'=>'1',
],
]);

Answer 1

try this
<input type="hidden" name="teacher_id" id="teacher_id" value="">
<?php
echo AutoComplete::widget([
'name' => 'Teacher',
'id' =>'ddd',
'clientOptions' => [
'source' => $data,
'autoFill'=>true,
'minLength'=>'1',
'select' => new \yii\web\JsExpression("function( event, ui ) {
// $('#teacher_id').val(ui.item.id);//#teacher_id is the id of hiddenInput.
console.log(ui.item.id);
}")
],
]);
