Resolved: Yii2 NavBar check isGuest leave empty or fill with multiple items
posted by admin on February 21, 2017

<?php
use yii\bootstrap\Nav;
use yii\bootstrap\NavBar;
use app\helpers\App;
use yii\helpers\Html;

NavBar::begin([
'brandLabel' => 'My Company',
'brandUrl' => Yii::$app->homeUrl,
'options' => [
'class' => 'navbar-inverse navbar-fixed-top',
],
]);
echo Nav::widget([
'options' => ['class' => 'navbar-nav navbar-right'],
'items' => [
['label' => App::t('Home'), 'url' => ['/site/index']],
Yii::$app->user->isGuest ? (
['label' => App::t('Login'), 'url' => ['/site/login']]
) : (
'<li>'
. Html::beginForm(['/site/logout'], 'post')
. Html::submitButton(
App::t('Logout').' (' . Yii::$app->user->identity->username . ')',
['class' => 'btn btn-link logout']
)
. Html::endForm()
. '</li>'
),
],
]);
NavBar::end();
?>

I want to add functionality like these:
1. I want to leave else empty
example

Yii::$app->user->isGuest ? (
['label' => App::t('Sign up', 'app2'), 'url' => ['/site/registration']]
) : (
[]//want to leave empty
),

2. I want multiple array
example

Yii::$app->user->isGuest ? (
['label' => App::t('Sign up0', 'app2'), 'url' => ['/site/zczczcxz']],
['label' => App::t('Sign up1', 'app2'), 'url' => ['/site/qweqweqe']],
['label' => App::t('Sign up2', 'app2'), 'url' => ['/site/asdasd']]
) : (
['label' => App::t('Sign up4', 'app2'), 'url' => ['/site/oipoiopi']],
['label' => App::t('Sign up4', 'app2'), 'url' => ['/site/oipoiopi']]
),

Both example not working and throwing errors, I think there is one decision for both situation with errorsRead more
