Question about XHTML and meta tag

Joel · 9th June 2013, 07:02

This is my sample page:

code:


<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="es">

	<head>

		<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=UTF-8" />

		<meta name="Generator" content="Geany 1.23.1" />

		<meta name="author" content="Joel Almeida Garc&iacute;" />

		<meta name="Date" content="06.06.2013 14:09:08" />

		<meta name="Robots" content="NOINDEX, NOFOLLOW" />

		<link href="data/style.css" rel="stylesheet" type="text/css" />

		<link rel="icon" type="image/png" href="data/favicon.png" />

		<script type="text/javascript" src="data/js.js" charset="UTF-8"></script>

		<title>Ciencias de la comunicaci&oacute;n II</title>

	</head>

        <body>

                 <p>Here goes date:</p> <!-- here goes  meta name="Date" contents -->

        </body>

</html>

My question is: Is it possible to show any of the meta tags info into the body of the page? For example show "Date"

You'd have to use php

Output the date metadata for the current page:

The meta date is:<?php $tags = get_meta_tags("http://".$_SERVER[HTTP_HOST].$_SERVER[REQUEST_URI]);
echo $tags['date'];?>

I was thinking something like that but it's been so long I couldn't remember. Kudos!

Why would you do it that way? That looks really slow and inefficient.

You may as well just use php to define some vars before you output the page, then reference them as you spit it out.

code:
<?php $metaDate = '06.06.2013 14:09:08'; ?><?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="es">

	<head>

		<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=UTF-8" />

		<meta name="Generator" content="Geany 1.23.1" />

		<meta name="author" content="Joel Almeida Garc&iacute;" />

		<meta name="Date" content="<?php echo $metaDate; ?>" />

		<meta name="Robots" content="NOINDEX, NOFOLLOW" />

		<link href="data/style.css" rel="stylesheet" type="text/css" />

		<link rel="icon" type="image/png" href="data/favicon.png" />

		<script type="text/javascript" src="data/js.js" charset="UTF-8"></script>

		<title>Ciencias de la comunicaci&oacute;n II</title>

	</head>

	<body>

	     <p><?php echo $metaDate; ?></p>

	</body>

</html>

Why would you need to know what the metadata was if you already knew? Other php makes the metadata. You need to read it out. i.e.... in wordpress. The post will write the metadata. If you want to use it, you'll need to read it out or get the data more directly from the database.

Put this in the body of a wordpress ( d r u p a l, joomla etc.)page:

Post date:<?php $tags = get_meta_tags("http://".$_SERVER[HTTP_HOST].$_SERVER[REQUEST_URI]);
echo $tags['date'];?> 
Post author:<?php $tags = get_meta_tags("http://".$_SERVER[HTTP_HOST].$_SERVER[REQUEST_URI]);
echo $tags['author'];?>

I'm just dealing with the exact problem that Joel posted, nothing else. I'm not concerned about other websites.

Most CMS type sites have an API where you can fetch this information. (For wordpress: http://codex.wordpress.org/Function_Reference/)
And if it's not available then just go in and extend stuff (cleanly) so you can get it.
The cost of doing this is smaller than fetching and parsing the page, especially if the requested page is not cached.

You're also making two requests with that example, so it'll be even slower.
Not that it matters because you are creating an infinite loop!
The page that is being generated is fetching itself (to get the meta data) which in turn is... fetching itself...
Try it yourself by using Joel's example as a base page.

I was looking for a generic solution. That does make a loop. I didn't think of it.

OK... so get_post_meta as a Wordpress function. getMetaData in Joomla. You've got to gyrate a little to get it out of D r u p a l.
