[SOLVED] Underscore messes up redirect

[backyard]

I've been using a redirect on my site for years without issue. Someone registers a username with an underscore and now for the username with the underscore doesn't work.

 

Options +FollowSymlinks

Options -Indexes

RewriteEngine on

RewriteRule ^([a-z0-9]+)$ /?L=users.profile&id=$1 [r=301,nc]

 

so if I enter

 

www.mysite.com/username

 

it works with a redirect to users.profile&id=username

 

now the person with an underscore in the username gets a not found error.

 

www.mysite.com/user_name

 

Naturally, the underscore may or may not be there and there could be multiple ones in any position.

 

Does anyone know if this can be fixed?

RewriteRule ^([a-z0-9]+)$ /?L=users.profile&id=$1 [r=301,nc]

 

Change to:

 

RewriteRule ^([a-z0-9_]+)$ /?L=users.profile&id=$1 [r=301,nc]

 

 

Your pattern says 1 a string starting with and ending with 1 or more letters or numbers.  Why would it work with an underscore?

You might want to also modify your registration script to enforce that usernames will match the same regex you are using in your rewrite.

Thanks that solved my problem. I knew it was missing I just didn't know where to add the underscore to me expression.
