Retrieving complete URL from page ($_GET[?]?)

[gjh42]

I'm working on a mod to highlight the current page link in ez-pages menus, and used $_GET['url'] to compare the page url with the link url. This seemed to be successful in initial trials, but now doesn't work, and my research seems to show that it doesn't exist.

What can I use to retrieve the complete current page URL? This may be a case of not using the right term to search with, as I would think it ought to be possible.
Where can I find a more or less complete list of $_GET[] fields? Or does such a list exist? I have looked in the forum, the wiki and my site's DTK so far.

$_GET without square brackets or an index will return the entire array of parameters being passed. Does that help?

[gjh42]

Thanks for that! It might help, though reassembling all the right parameters in the right order would be a real pain. I don't suppose you know if the parameters are ordered in the same sequence they appear in the address bar? If they are, an implode() might possibly work? Or maybe not, as there are different delimiters between different parts of the URL, and things like "main_page=" would also have to be added back in.

The $_GET array is associative, so the order doesn't matter. URLs don't care about the order either.

The point is that I have to compare a link string which could have a huge number of different components with the page URL it might have called, and it seems a nightmare to compare all possible link elements with URL elements.

I have used $_SERVER['REQUEST_URI']

Are you looking maybe for the zen_get_all_params() function which is used to rebuild a URL excluding any parameters passed in an array

Example usage:

zen_href_link($current_page_base, zen_get_all_get_params(array('currency','language'))) 

to strip the language and parameter params and give back what's left of the page's URL.

AHA! I knew I had seen something that would show that. That's what it was. Thank you so much!


Since the ez-page link will be in the form of a complete URL, comparing that with the actual page's complete URL will be easiest. It will be okay if the page URL runs longer than the link.

If this is for ezpages, don't you care only about the "main_page" and "page" parameters?

Oh I think I see. You're refering to to the URLs of EZ-Pages themselves, but to the URLs that they forward onto?
