我对这个话题很陌生。我有一个使用Yii框架的PHP编写的网站。在我的自定义CDN中，我通过它注入了内容，我的开发人员设计了一个部分，可以为各个页面分配不同的Meta标签或SEO标签。我的问题是该机制不起作用，实际上，当我说出元描述时，它在所有页面上都一样。我无法访问我的开发者来更正此问题。在下面，我提供了layout和Metadata.php的代码。 如前所述，我是这个主题的新手，不知道应该提交哪些代码进行考虑。如果需要更多代码，请询问我。
我的目标是更正我的后端条目（“元数据列表”部分），以使每个页面都具有我提供的唯一元标记。
$metadata = \common\models\base\Metadata::find()->where(['page_routing' =>
Yii::$app->controller->id."/". Yii::$app->controller->action->id ])->one();
if ( empty($metadata ) )
$metadata = \common\models\base\Metadata::find()->where(['id' => 1 ])-
>one();
?>
<?php $this->beginPage() ?>
<!DOCTYPE html>
<html lang="<?= Yii::$app->language ?>">
<head>
<meta charset="<?= Yii::$app->charset ?>">
<?php echo Html::csrfMetaTags() ?>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="X-UA-Compatible" content="IE=edge"/>
<meta name="viewport" content="width=device-width, initial-scale=1,
maximum-scale=1, user-scalable=no"/>
<meta name="robots" content="<?=$metadata->meta_robots?>"/>
<link rel="canonical" href="https://physexams.com/<?=Yii::$app->controller-
>id."/". Yii::$app->controller->action->id?>" />
<meta property="og:image" content="<?=$metadata->og_image?>"/>
<meta property="og:title" content="<?=$metadata->og_title?>‌"/>
<meta property="og:description" content="<?=$metadata->og_description?>"/>
<meta name="twitter:image" content="<?=$metadata->twitter_image?>"/>
<meta property="og:locale" content="en_CA" />
<meta name="googlebot" content="index" />
<meta name="revisit-after" content="1 Days" />
<meta name="doc-class" content="Living Document" />
<meta name="language" content="english">
<?= Html::csrfMetaTags() ?>
<link rel="publisher" href="<?=$metadata->publisher?>" />
<title><?= Html::encode($this->title) ?></title>
<?php $this->head() ?>
在上面，为简短起见，我剪切了其他不需要的元标记并提交了部分代码。如果需要完整的代码，我可以提交。 和Metadata.php的代码
