How to pass URL variables into a WordPress page

Question

This has been asked on here (over a year ago), but apparently not answered, and WordPress is always evolving so maybe theres a good solution now. I want to pass variables to a WordPress page via the url (similar to CodeIgniter uri helper segments).

Currently I can do this...

My profile page is: http://website.com/profile

I can pass a variable like this: http://website.com/profile?username=johndoe

I want to pass the variable in like this: http://website.com/profile/johndoe or http://website.com/profile/username/johndoe

There has to be some sort of helper function, right?

Answer 1

Assuming that your wp installation is using permalinks, so the .htaccess features, you should put on TOP of your .htaccess file the following :

Options +FollowSymlinks
RewriteEngine on
RewriteRule ^profile/(.*)$ /profile?username=$1 [NC]

Answer 2

Append to your .htaccess file in the root folder something like

 RewriteRule ^profile/?([_0-9a-z-]+)?/?$ http://website.com/profile?username=$1 [R=301,L]

after the other RewriteRules
