get variable from url?

Question

say i've got a url http://bfami.modernactivity.co.uk/category/museum/orderby/date/order/desc/

that works with;

add_rewrite_rule( 'category/(.+?)/orderby/([^/]+)/order/([^/]+)(/page/?([0-9]{1,}))?/?$', 'index.php?category_name=$matches[1]&paged=$matches[5]&orderby=$matches[2]&order=$matches[3]', 'top' );

how do i get the value of orderby or order on a page? Think wordpress removes the GET values which is what i'd normally use...

Just want to highlight the active order filter on the page!

Answer 1

You are looking for get_query_var() function:

$orderby = get_query_var('orderby');

Answer 2

think its: $wp_query->query_vars['orderby'].

You can dump all the query string variables by var_dump($wp_query->query_vars); It should be in there.

Answer 3

ended up with;

class="<?=( strpos(  $oby ,'date' ) ? 'active' : null )?>"

though can imagine i'll need to get this working on one job or the other...

thanks all!
