Php 如何在yii引导窗口小部件中获得两个链接？

如何在Yii2引导程序中显示注册和登录链接

我是Yii框架的新手

错误：语法错误，意外的'=>'（T_双箭头），应为']'

回声导航：：小部件([ '选项'=>['class'=>'导航栏导航栏右']， '项目'=>[ ['label'=>'Home'，'url'=>['/site/index']]， ['label'=>'About'，'url'=>['/site/About']]， ['label'=>'Contact'，'url'=>['/site/Contact']]， Yii:：$app->user->isGuest( ['label'=>'Login'，'url'=>['/site/Login']] ['label'=>'Register'，'url'=>['/site/Register']] ) : ( “

” .Html:：beginForm（['/site/logout']，'post'，['class'=>'navbar form']）） .Html:：submitButton( '注销（'.Yii:：$app->user->identity->username.'）， ['class'=>'btn-btn-link'] ) .Html:：endForm（） “

” ) ], ]); 逗号无帮助：语法错误，意外“，”

你应该在这里加逗号

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

试试看，这段代码正在运行

<?php
NavBar::begin([
    'brandLabel' => 'My Company',
    'brandUrl' => Yii::$app->homeUrl,
    'options' => [
        'class' => 'navbar-inverse navbar-fixed-top',
    ],
]);
$menuItems = [
    ['label' => 'Home', 'url' => ['/site/index']],
    ['label' => 'About', 'url' => ['/site/about']],
    ['label' => 'Contact', 'url' => ['/site/contact']],
];
if (Yii::$app->user->isGuest) {
    $menuItems[] = ['label' => 'Signup', 'url' => ['/site/signup']];
    $menuItems[] = ['label' => 'Login', 'url' => ['/site/login']];
} else {
    $menuItems[] = '<li>'
        . Html::beginForm(['/site/logout'], 'post')
        . Html::submitButton(
            'Logout (' . Yii::$app->user->identity->username . ')',
            ['class' => 'btn btn-link']
        )
        . Html::endForm()
        . '</li>';
}
echo Nav::widget([
    'options' => ['class' => 'navbar-nav navbar-right'],
    'items' => $menuItems,
]);
NavBar::end();
?>

试试这个

<?php
    $items[]=[
            ['label' => 'Home', 'url' => ['/site/index']],
            ['label' => 'About', 'url' => ['/site/about']],
            ['label' => 'Contact', 'url' => ['/site/contact']]
        ];
           if( Yii::$app->user->isGuest) {
           $items[]= ['label' => 'Login', 'url' => ['/site/login']];
             $items[]= ['label' => 'Register', 'url' => ['/site/Register']];
           }else{
               $items[]= '<li>'
                . Html::beginForm(['/site/logout'], 'post', ['class' => 'navbar-form'])
                . Html::submitButton(
                    'Logout (' . Yii::$app->user->identity->username . ')',
                    ['class' => 'btn btn-link']
                )
                . Html::endForm()
                . '</li>';
           }

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

请通过链接实现导航小部件。您得到了答案还是需要更多帮助？

<?php
    $items[]=[
            ['label' => 'Home', 'url' => ['/site/index']],
            ['label' => 'About', 'url' => ['/site/about']],
            ['label' => 'Contact', 'url' => ['/site/contact']]
        ];
           if( Yii::$app->user->isGuest) {
           $items[]= ['label' => 'Login', 'url' => ['/site/login']];
             $items[]= ['label' => 'Register', 'url' => ['/site/Register']];
           }else{
               $items[]= '<li>'
                . Html::beginForm(['/site/logout'], 'post', ['class' => 'navbar-form'])
                . Html::submitButton(
                    'Logout (' . Yii::$app->user->identity->username . ')',
                    ['class' => 'btn btn-link']
                )
                . Html::endForm()
                . '</li>';
           }

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