I am new to Yii2 and recently downloaded a basic-app version of the framework.
There is a code snippet in the "main.php" file:

echo Nav::widget([

    'options' => ['class' => 'navbar-nav navbar-right'],

    'items' => [

        ['label' => 'Main', 'url' => ['/site/index']],

        ['label' => 'Countries', 'url' => ['/country/countries']],

        ['label' => 'About us', 'url' => ['/site/about']],

        ['label' => 'Contacts', 'url' => ['/site/contact']],

        Yii::$app->user->isGuest ? (

                ['label' => 'Login', 'url' => ['/user/login']]

        ) : (

            '<li>'

            . Html::beginForm(['/user/logout'], 'post')

            . Html::submitButton(

                'Logout(' . Yii::$app->user->identity->username . ')',

                ['class' => 'btn btn-link logout']

            )

            . Html::endForm()

            . '</li>'

        )

    ]

]);

where I want to add registration link like this:

Yii::$app->user->isGuest ? (

                ['label' => 'Login', 'url' => ['/user/login']],

                ['label' => 'Register', 'url' => ['/user/registration']]

        ) : (

            '<li>'

            . Html::beginForm(['/user/logout'], 'post')

            . Html::submitButton(

                'Logout(' . Yii::$app->user->identity->username . ')',

                ['class' => 'btn btn-link logout']

            )

I know this peace of code is wrong, but I want to ask, how can I do this in right way?

My Answer:
To add a new temporary item to the NavBar items using isGuest, you can modify the code as follows:

php
echo Nav::widget([
'options' => ['class' => 'navbar-nav navbar-right'],
'items' => [
['label' => 'Main', 'url' => ['/site/index']],
['label' => 'Countries', 'url' => ['/country/countries']],
['label' => 'About us', 'url' => ['/site/about']],
['label' => 'Contacts', 'url' => ['/site/contact']],
Yii::$app->user->isGuest ? (
['label' => 'Login', 'url' => ['/user/login']],
['label' => 'Register', 'url' => ['/user/registration']]
) : (
'

'
. Html::beginForm(['/user/logout'], 'post')
. Html::submitButton(
'Logout(' . Yii::$app->user->identity->username . ')',
['class' => 'btn btn-link logout']
)
. Html::endForm()
. '

'
)
]
]);


This code snippet will display both the "Login" and "Register" links in the NavBar when the user is a guest. When the user is logged in, it will display the "Logout" link as before.

Make sure to adjust the URLs and labels according to your application's routes and requirements.
