Yii 框架：从数据库中选择相关记录时如何从数据库中获取 ID

Question

我在网页上有带 Autocomplete::widget 的文本编辑框。自动完成从数据库填充。当我开始键入并选择自动完成项目（在我的例子中是数据库中的名字）时，我需要从数据库中获取关联的 ID。如何实施？

<?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">
ФИО
    <?php 

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

试试这个

  <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);
                 }")
     ],
     ]);
