当我在 中传递静态内容时图像张贴在我的 Twitter 墙上，但如果我将变量作为<meta name="og:image" content="<?php echo $image?>">图片没有贴在我的墙上.
When I pass static content in <meta name="og:image" content="http://abc.in/def.jpg">
image is posted on my Twitter wall, but if I pass variable as
<meta name="og:image" content="<?php echo $image?>">
image is not posted on my wall.

推荐答案
$image 后缺少分号可能是问题所在(如评论中所述):
The missing semicolon after $image could be the issue (as mentioned in the comments):
<meta name="og:image" content="<?php echo $image; ?>">
<meta name="og:description" content="<?php echo $description; ?>">
<meta name="og:title" content="<?php echo $title; ?>">
修复代码后，通过 Twitter 卡验证器运行页面以确保一切都正确显示.希望它能让您了解发生了什么问题.
Once you've fixed the code, run the Page through the Twitter Card validator to make sure everything appears correctly. It should hopefully give you an idea of what's going wrong.
