How to add url parameter to the current url?

Question

Currently I\'m at

http://example.com/topic.php?id=14 

and I want to make a link to

http://example.com/topic.php?id=14&         


        

Answer 1

There is no way to write a relative URI that preserves the existing query string while adding additional parameters to it.

You have to:

topic.php?id=14&like=like
