dynamically print url

[Lambneck]

Is there a way to dynamically print the url of a web page once it loads? If so, how? This is for metadata purposes.

Thanks!

Besides with $_SERVER["REQUEST_URI"]?

[Lambneck]

So this will do it? <?php print $_SERVER["REQUEST_URI"]; ?>

Great thanks! That's all i needed to know.

$url = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

[Lambneck]

So would something like the following work?

 

<link
rel="canonical" 
href="<?php $url = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; print $url; ?>"
>

[requinix]

Yes, but either (a) you aren't using rel=canonical correctly or (b) you don't need to specify it because the canonical URL will always be the page's URL - you aren't adding any useful information and are implying things that might not be true.

 

The idea is that there could be multiple URLs to access a certain page (notably: URLs with varying query string parameters), so you specify a canonical URL to provide a "primary" location of the page. Google's Webmaster Tools has a page on the subject.

Thanks requinix. I see that's a problem. So how then can i dynamically generate the canonical url to match the pages content?
