Yii2 DetailsView Operations

DetailView is best used for displaying a model in a regular format (e.g. each model attribute is displayed as a row in a table.) The model can be either an instance of yii\base\Model or an associative array.

DetailView uses the $attributes property to determines which model attributes should be displayed and how they should be formatted.

A typical usage of DetailView is as follows:

echo DetailView::widget([
    'model' => $model,
    'attributes' => [
        'title',               // title attribute (in plain text)
        'description:html',    // description attribute in HTML
        [                      // the owner name of the model
            'label' => 'Owner',
            'value' => $model->owner->name,
        ],
        'created_at:datetime', // creation date formatted as datetime
    ],
]);

Examples of DetailsView

View Code

<?php

use yii\helpers\Html;

use yii\widgets\DetailView;

use backend\modules\tools\models\Groupitems;

$this->title = 'Note : '. $model->slno;

$this->params['breadcrumbs'][] = ['label' => 'Students Instructions Note', 'url' => ['index']];

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

?>

<div class="studentsgblinvoicenote-view box box-body table-responsive">  

    <p>

        <?= Html::a('Update', ['update', 'ccid' => $model->ccid, 'slno' => $model->slno], ['class' => 'btn btn-primary']) ?>

        <?= Html::a('Delete', ['delete', 'ccid' => $model->ccid, 'slno' => $model->slno], [

            'class' => 'btn btn-danger',

            'data' => [

                'confirm' => 'Are you sure you want to delete this item?',

                'method' => 'post',

            ],

        ]) ?>

    </p>

    <?= DetailView::widget([

        'model' => $model,

        'attributes' => [

            'slno',

            'course',

             'note1',

            'note2'                  

        ],

    ]) ?>

</div>

Controller action

 public function actionView($ccid, $slno)
    {
        return $this->render('view', [

                'format'=>'raw',
                'value' => nl2br($model->note1 ),

Changing value of an attribute in DetailView widget

The above example call from function to display DetailsView

                'value'  => Groupitems::getGroupitems($model->course),       

<?= DetailView::widget([
    'model' => $model,
    'attributes' => [
        'name',
        'max_people_count',
        'type',
        [
             'attribute' => 'recurring',
             'format'=>'raw',
             'value'=> function ($model) {
                        if($model->recurring == 1)
                        {

                            return 'yes';

                        } 
                        else {
                        return 'no';
                        }
                      },
        ],
        'day',
        'time',
        ...

'value' => $model->recurring == 1 ? 'yes' : 'no'

The nl2br() function inserts HTML line breaks (<br> or <br />) in front of each newline (\n) in a string.
