WordPress shortcodes for current page and parent urls

get-url-shortcode.php

function get_url($atts) {
 $pageURL = 'http';
 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
 $pageURL .= "://";
 if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
 } else {
  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
 }
 return $pageURL;
}

function get_parenturl($atts) {
 $url = rtrim(get_url($atts),"/");
 $url = substr($url, 0, strrpos($url,"/"));
 if(strlen($url)>strlen("http://" + $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"])) 
  return $url;
 else
  return "http://" + $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"];
}

add_shortcode('url', 'get_url'); 
add_shortcode('parentUrl', 'get_parenturl'); 

The Shortcode API wiki warns against using hyphens in shortcode names. Apparently there's a bug in the shortcode api that causes it to treat [parent] and [parent-url] as the same shortcode. This has bit me before, which is why I noticed it :)

As an alternative, parent_url or parentUrl should work.

Thanks, changed to parentUrl.
