Yii2。如果陣列

Question

默認Yii2佈局內部條件與速記導航欄，如果條件登錄菜單項

echo Nav::widget([ 
    'options' => ['class' => 'navbar-nav navbar-right'], 
    'items' => [ 
     /* 
     ... 
     some items 
     ... 
     */ 
     Yii::$app->user->isGuest ? (
      ['label' => 'Login', 'url' => ['/site/login']] 
     ) : (
      '<li>' 
      . Html::beginForm(['/site/logout'], 'post') 
      . Html::submitButton(
       'Logout (' . Yii::$app->user->identity->username . ')', 
       ['class' => 'btn btn-link'] 
      ) 
      . Html::endForm() 
      . '</li>' 
     ), 
    ], 
]); 

如何，我可以添加幾個條目到這種狀況呢？ 這不起作用（語法錯誤 - 意外「」）

Yii::$app->user->isGuest ? (
      ['label' => 'Login', 'url' => ['/site/login']], 
      ['label' => 'Register', 'url' => ['/site/register']] 
) :

似乎更容易項添加到陣列的小部件定義之外。

$items = /* some items */; 
if (Yii::$app->user->isGuest) { 
    $items[] = ['label' => 'Login', 'url' => ['/site/login']]; 
    $items[] = ['label' => 'Register', 'url' => ['/site/register']]; 
} else { 
    $items[] = ['your html']; 
} 

echo Nav::widget([ 
    'options' => ['class' => 'navbar-nav navbar-right'], 
    'items' => $items, 
]);
