问题
I am using
<?php $image='http://abc.in/def.jpg'; ?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta name="twitter:card" content="summary">
<meta name="og:image" content="<?php echo $image?>">
<meta name="og:description" content="<?php echo $description; ?>">
<meta name="og:title" content="<?php echo $title; ?>">
<meta name="twitter:url" content="http://keyss.in">
<meta name="twitter:app:id:iphone" content="">
<meta name="twitter:app:id:ipad" content="">
<meta name="twitter:app:id:googleplay" content="">
<meta name="twitter:app:url:iphone" content="">
<meta name="twitter:app:url:ipad" content="">
<meta name="twitter:app:url:googleplay" content="">
</head>
</html>
code for my Twitter post.
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.
How can I pass dynamic variable in image content?
回答1:
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; ?>">
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.
