Rewrite URL based on variable

Question

I need to add a variable of the username to all of my URL's when the user is logged in.

So for example it would be:

www.example.com/?user=user1
www.example.com/category1/product1/?user=user1

The reason I need to add the variable is for sending the page to a PDF service as each user has a unique style to their template.

I have my variable set but how can I rewrite the page URL to include the variable if it isn't already included on the URL using php?

Why do you want to do it via php? Shouldn't you try some webserver configuration? — Muc

Is the PHP application that has the user's credentials the same as the one that generates the PDF? If so, you might consider using a session object instead of URL injection. — PaulProgrammer

If you absolutely must use php, could you use a HTTP 301 redirect? — Muc

@PaulProgrammer unfortunately not, using a wordpress install which generates user credentials and and external service for PDFing — Vince P

Is the url with the variable supposed to trigger a redirect? — Flosculus

Apache can't know if the user is logged in, it concerns your PHP code. In this case, I think the best solution is to add a SESSION variable like :

$_SESSION['user'] = 'user1';

And instead of check if the user parameter exists, you will have to check if the $_SESSION['user'] exists. That will be easier and safer.

What you're looking for isn't actually php, it's an apache module in your .htaccess file. This is the best blog I've seen on the subject: http://www.addedbytes.com/articles/for-beginners/url-rewriting-for-beginners/

This only works if apache knows about the user credentials, which it may not if user management is done in the application.

why? "?user=user1" is just a string in the initial url that remains unchanged in the final url. It can be simply regexed like any other part of the url

I read that OP wants to add the ?user=user1 to the URL, which isn't there when it appears in Apache.
