为什么什么都不加载 Yii 2

Dmy*_*yuk 1 php yii yii2

当我要“查看”视图时,没有加载任何内容,甚至是包含 HTML 页眉和页脚的默认布局,因此它在源代码中不显示任何内容。

来自控制器的代码:

    public function actionArt($type){
        $compositions = Compositions::find()
            ->select(['id', 'name'])
            ->where('type' == $type)
            ->asArray()
            ->all();

        return $this->render('art', ['compositions' => $compositions]);
    }

    public function actionView($id){
        $info = Compositions::find()->where($id)->all();
        $this->render('view', ['info' => $info]);
    }

视图中的代码:

“艺术”视图:

<?php

/* @var $compositions */

use yii\helpers\Html;
use yii\helpers\Url;

?>

<div class="site-art">
    <?php foreach ($compositions as $composition){
        Html::a(Html::encode($composition['name']), ['site/info', 'id' => $composition['id']]);
        echo "<a href='" . Url::to(['site/view', 'id' => $composition['id']], true) . "'>{$composition['name']}</a><br>";
    } ?>
</div>

“查看”查看:

<?php

/* @var $info */

use yii\helpers\Html;
use yii\helpers\Url;

var_dump($info);

?>

<div class="site-info">

您必须返回的结果render(),而不仅仅是调用它。

return $this->render('view', ['info' => $info]);

还有这个

Html::a(Html::encode($composition['name']), ['site/info', 'id' => $composition['id']]);

现在什么都不做。你必须回应它,所以它基本上会和它现在下面的那一行做同样的事情。但更好,因为它对$composition['name'].
