Get URL from Shortcode 2

Hi – I wanted to build upon this post:

Is there a way to only extract part of the URL??
My domain is like this somebody.com/?referrer=ABC123
I just want to show the current URL’s referrer ID which is ABC123

What part do I have to change in Vladimir’s code to change this to only show the referral ID in my case?

Many thanks!!

Is there a shortcode or a way to create a shortcode to get the current Site URL?
I need it for when I develop and move from one site to another and have not found a good way yet and this seems like it might do the trick

Hi @brandimor,

there is no such shortcode, but you can easily create it yourself.

Add the following snippet to the end of the functions.php file of your active theme or into a site-specific plugin:

add_action( ‘init’, function() {

add_shortcode( ‘site_url’, function( $atts = null, $content = null ) {
return site_url();
} );

} );
Then just use the following shortcode: [site_url]

Do not use this code on PHP version 5.2 or lower.
