使用php和mysql创建动态元标记

我试图弄清楚如何创建动态元标记，使用mysql数据库获取信息

现在我有

<meta name="twitter:card" content="player" />
<meta name="twitter:description" content="Share your sounds. Sign up with your Twitter account." />
<meta name="twitter:site" content="@Gabberus" />
<meta name="twitter:title" content="{$title}" />

<meta name="twitter:image" content="https://gabber.us/uploads/media/{$art}" />
<meta name="twitter:player" content="https://gabber.us/embed.php?id={$id}" />

现在，我的问题是。是{$title}将设置正确的标题（歌曲名称），但{$id}{$name}和{$art}（id、name、art是数据库列）不会从数据库中获取任何信息

我没有PHP方面的经验，任何输入都会很好

是否可以在我的config.php文件中添加类似的内容 $CONF['tplayer']=''

这样我就可以在meta中使用{$tplayer}

如果我完全错了，请让我知道，任何帮助都是感激的

最好的， 杰米

您可以向我们展示您的模板代码，这很好。但是我们不知道模板是如何获得$title的。告诉我们吧，因为问题就在这里。我们不知道数据是否已经从您的数据库中提取出来。告诉我们您使用哪种CMS。Wordpress？嘿，PaulH，我添加了index.php，可以从数据库中提取一些信息，我相信？我正在使用一个名为phpsound的php脚本。您向我们展示了您的模板代码，这很好。但是我们不知道模板是如何获得$title的。告诉我们吧，因为问题就在这里。我们不知道数据是否已经从您的数据库中提取出来。告诉我们您使用哪种CMS。Wordpress？嘿，PaulH，我添加了index.php，可以从数据库中提取一些信息，我相信？我正在使用一个名为phpsound的php脚本。
