What literal characters should be escaped in a regex?

RewriteRule ^profile/[A-Za-z_-\d\^\.]/*$ ./index.php?page=showuser&username=$1

I am new to mod rewrite. Could someone tell me what's wrong with my pattern here? I am trying to only let names passed in that have characters, numbers, -, ^, _ and . symbols but it will give me an error when I use that syntax.

Answer 1

4 things:

• missing a slash at the start
• you forgot a + after your character class :)
• you also forgot to capture the username :p
• you should always put the - character in caracter classes at the beginning fo the class

(also, you don't need to escape anything else than ] inside a character class)

RewriteRule ^/profile/([-A-Za-z_\d^.]+)/*$ ./index.php?page=showuser&username=$1
