Trying to get propertyof non-object yii

Question

I am starting to learn Yii framework so I am a beginner. I am struggling. I want to fetch the data from database using yii2 framework. This is my controller

 public  function actionView()
{


    $this->view->title = 'List Hotels';
    $items = ArrayHelper::map(Hotel::find()->all(), 'id', 'name');

        return $this->render('index', [
            'items' => $items,


        ]);

}

In my view file, I used the fetched data as below;

   <?php

/* @var $this yii\web\View */

use yii\helpers\Html;

 $this->title = 'Hotel list';
 $this->params['breadcrumbs'][] = $this->title;
 ?>

<?php foreach ($items as $item): ?>

<p> <?= $item-> name ?></p>
<p> <?= $item->address ?></p>
<p> <?= $item->description ?></p>


<?php endforeach; ?>

When I wrote var_dumps($items) under $items I can see the datas. However in the view It says Trying to get property 'name' of non-object. What did I wrong here please guide me. THanks for your time.

ArrayHelper::map()

Returns an array where, in your case, second argument passed is a key, the third is a value. So you need to access its elements as an array elements instead of class properties. Like:

<?php foreach ($items as $key => $value): ?>

    <p> <?= $key ?></p>
    <p> <?= $value ?></p>

<?php endforeach; ?>

More details here: https://www.yiiframework.com/doc/api/2.0/yii-helpers-basearrayhelper#map()-detail

But if you need to access data as class properties change the line in your controller:

$items = ArrayHelper::map(Hotel::find()->all(), 'id', 'name');

to:

$items = Hotel::find()->all();
