获取标题以匹配链接标题

Question

我正在开发一个类似 Digg 的网站，我希望 cmets 页面的标题与链接标题相匹配，这里是 cmets 文件代码：

class CommentsPage extends Page {

    function __construct($title = '')
    {
        $this->setTitle($title);
    }

    function header()
    {
        parent::header();
    }

    function showAllComments($article_id, $param)
    {


        $article = Article::getById($article_id);
        if(!empty($article))
        {
            ?>
            <div class="news_item">
                <a href="/index.php?action=vote&param=<?php echo $article->getId(); ?>"><img alt="vote button" class="vote_button" height="10" src="assets/images/vote2.png" width="10" class="border_less" /></a>
                <h2 class="news_item_title"><b><a href = "<?php echo $article->getUrl(); ?>"><?php echo $article->getTitle(); ?></a></b></h2>
                <span class="news_item_url">(<?php echo $article->getUrlDomain(); ?>)</span>
                <div class="news_item_info"><?php $points = $article->getPoints(); echo $points > 1 ? "$points points" : "$points point"; ?> by <a href="/index.php?action=user&param=<?php echo $article->getUsername(); ?>"><?php echo $article->getUsername(); ?></a> <?php echo $article->getElapsedDateTime(); ?></div>
                <p class="news_item_content"><?php echo $article->getDescription(); ?></p>
            </div>
            <?php
            $this->showSubmitForm($article);
        }

我知道我必须更改“$this->setTitle($title);”对于这样的东西： $article->getTitle();但我尝试了不同的方法，只是显示错误。

我想我不够清楚：页面顶部的标题要更改并与该页面的新闻标题相同（这是网站：kiubbo.com）谢谢

这个怎么样：

class CommentsPage extends Page
{
    private $article;

    function __construct($article_id)
    {
        $this->article = Article::getById($article_id);
        if(!empty($article))
        {
            $this->setTitle($article->getTitle());
        }
        else
        {
            //Throw an exception
        }
    }

    function header()
    {
        parent::header();
    }

    function showAllComments($param)
    {
        if(!empty($this->article))
        {
        ?>
            <div class="news_item">
                <a href="/index.php?action=vote&param=<?php echo $this->article->getId(); ?>"><img alt="vote button" class="vote_button" height="10" src="assets/images/vote2.png" width="10" class="border_less" /></a>
                <h2 class="news_item_title"><b><a href = "<?php echo $this->article->getUrl(); ?>"><?php echo $this->article->getTitle(); ?></a></b></h2>
                <span class="news_item_url">(<?php echo $this->article->getUrlDomain(); ?>)</span>
                <div class="news_item_info"><?php $points = $this->article->getPoints(); echo $points > 1 ? "$points points" : "$points point"; ?> by <a href="/index.php?action=user&param=<?php echo $this->article->getUsername(); ?>"><?php echo $this->article->getUsername(); ?></a> <?php echo $this->article->getElapsedDateTime(); ?></div>
                <p class="news_item_content"><?php echo $this->article->getDescription(); ?></p>
            </div>
        <?php
        $this->showSubmitForm($this->article);
    }
}

我有点困惑。您只是在寻找属性 getter/setter 吗？

<?php
class CommentsPage extends Page {

    protected $title;

    function __construct($title = '')
    {
        $this->setTitle($title);
    }

    //  This function does nothing, by the way
    function header()
    {
        parent::header();
    }

    public function setTitle( $title )
    {
        $this->title = $title;
    }

    public function getTitle()
    {
        return $this->title;
    }

    function showAllComments($article_id, $param)
    {


        $article = Article::getById($article_id);
        if(!empty($article))
        {
            ?>
            <div class="news_item">
                <a href="/index.php?action=vote&param=<?php echo $article->getId(); ?>"><img alt="vote button" class="vote_button" height="10" src="assets/images/vote2.png" width="10" class="border_less" /></a>
                <h2 class="news_item_title"><b><a href = "<?php echo $article->getUrl(); ?>"><?php echo $this->getTitle(); ?></a></b></h2>
                <span class="news_item_url">(<?php echo $article->getUrlDomain(); ?>)</span>
                <div class="news_item_info"><?php $points = $article->getPoints(); echo $points > 1 ? "$points points" : "$points point"; ?> by <a href="/index.php?action=user&param=<?php echo $article->getUsername(); ?>"><?php echo $article->getUsername(); ?></a> <?php echo $article->getElapsedDateTime(); ?></div>
                <p class="news_item_content"><?php echo $article->getDescription(); ?></p>
            </div>
            <?php
            $this->showSubmitForm($article);
        }
    }
}
