Passing URL Parameters to all internal links. Or Persistent URL Variables

Hi there all,

I am looking for the exact same thing. I have chatted to a colleague about this too and he suggested doing it server-side – i.e. adding it as a Condition/Rule to the htaccess or httd config on the server … Not entirely sure of the proper/correct way to keep this parameter throughout a users website journey. How is it done?

Thanks in advance

You could do something like this:

function wprdcv_param_redirect(){
	if( !is_admin() && !isset($_GET['CUSTOM']) ){
		$location = "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
		$location .= "?CUSTOM=PARAM1";
		wp_redirect( $location );
	}
}
add_action('template_redirect', 'wprdcv_param_redirect');

Just replace CUSTOM and PARAM1 in the above code and add it to your functions.php

Hi WP Gurus

Great thanks this works quite well but not too sure of the stability and staticity of it. I’d would like to know:

If https://www.website.com it should stay https://www.website.com (without the ‘id’ parameter)
If https://www.website.com?id=1234 it should stay https://www.website.com?id=1234 and all other links that go on from here should have ?id 1234 at the end
If, for another user it is https://www.website.com?id=5678 all the links that user clicks should end with ?id=5678

Hope that makes sense?

Thanks again

In its current state the code will add the same id for all users.

Thanks mate. Please advise on how to make it a different unique ID per user? And if there is no ID (and parameter) than no parameter is shown in all links going ferther?

Thanks again

I have the same need as listed by previous member:

1. If https://www.website.com it should stay https://www.website.com (without the ‘id’ parameter)

2. If https://www.website.com?id=1234 it should stay https://www.website.com?id=1234 and all other links that go on from here should have ?id 1234 at the end

The solution listed above does add a parameter to the url, however it adds it everytime. So point 1. above is not effective i.e if someone goes to https://www.abc.com, the solution suggested takes user to https://www.abc.com/id=xyz

Can we make point 1. above happen?

@vipulratten I’m struggling with the exact same thing!
