Symfony2 - 页面查看计数器

Question

我正在尝试为帖子添加页面视图计数器,这是用户查看次数最多的.我在Post实体中添加了一个属性$ viewCount,它是一个整数.

我希望每次用户点击特定帖子的节目页面时都会对此进行计数.

要逐步完成整个过程,我需要设置一个计数器,每次查看时添加+1,将其存储在数据库中,然后查询,然后将其传回给Twig.

搜索hrs后我不知道怎么做的两部分是:

1)每次用户查看页面时如何添加(我知道你想以某种方式使用+1)

2)如何查询大多数页面视图以传递给控制器​​和树枝

的showAction

/**
 * Show Post
 *
 * @param $slug
 * @throws \Symfony\Component\HttpKernel\Exception\NotFoundHttpException
 * @return array
 *
 * @Route("/post/{slug}", name="acme_demo_show")
 * @Template("AcmeDemoBundle:Page:show.html.twig")
 */
public function showPostAction($slug)
{
    $article = $this->getDoctrine()->getRepository('AcmeBundle:Post')
        ->findOneBy(array(
            'slug' => $slug
        ));

    if (null === $article) {
        throw $this->createNotFoundException('Post was not found');
    }

    // Increment views each time user clicks on an article
    $em = $this->getDoctrine()->getManager();
    $views = $article->getViews();
    $article->setViews($views + 1);
    $em->flush();

    return array(
        'article' => $article,
    );
}

侧边栏动作

public function sidebarAction()
{
    $em = $this->getDoctrine()->getManager();

    $post = $em->getRepository('AcmeDemoBundle:Article')
        ->getMostRecentArticles(5);

    if (!$post) {
        throw $this->createNotFoundException('No posts were found');
    }

    $articles = $this->getDoctrine()->getRepository('AcmeDemoBundle:Article')
        ->findBy(array(
            array(
                'views' => 'ASC'
            )
        ));

    return array(
        'post' => $post,
        'articles' => $articles
    );
}

枝条

<h3>Most Popular Articles</h3>
    {% for article in articles %}
        <a href="{{ path('acme_demo_article_show', { slug: article.slug }) }}" class="anchor" style="text-decoration: none">{{ article.title }}</a><br>
    {% endfor %}

Answer 1

如果你想在用户点击链接时增加计数器,你需要使用AJAX javascript.或者你可以在你的帖子的控制器中使用纯PHP进行以下操作:

$views = $article->getViews();
$article->setViews($views + 1);
$em->persist($article);
$em->flush();

最佳做法是向increment()您的Article实体添加方法.

然后,按视图查询文章:

 $articles = $this->getDoctrine()->getRepository('AcmeBundle:Post')
        ->findBy(array(), array('views' => 'ASC'));

但更好的做法是在实体的存储库中编写自己的方法.

知识库

public function getMostPopularArticles()
{
    return $this->createQueryBuilder('article')
        ->select('article')
        ->orderBy('article.views', 'DESC')
        ->getQuery()
        ->execute();

}
