I hope you can help me with the following:
I have this URL of my website that uses wordpress link where link is a post, the post varies in number and ? n = kitchen that is a variable that I will add using $ _GET ['n']) to give an additional title to the post
What I want to do is change that url to link and make it more friendly to my visitors, thanks in advance for your answers
For that you must use the Rewrite Rules . You must add a new rule using the function add_rewrite_rule() . In the Examples section of this page there is one that I think will be of use to you. You should also use the add_rewrite_tag() function to call n using $wp_query->query_vars['n']
In general, this is a somewhat complicated topic, I recommend using Rewrite Rules Inspector , it's going to to be very helpful ...
Greetings.
