I have a regex pattern that matches a URL "slug" which I use to redirect all URI's with one segment that contain alphanumeric characters and hyphens(I.E. mysite.com/about-us) to my pages controller. My problem is that I have a separate controller for my home page, so I want to exclude the string "home" from any matches. How can I do this with the pattern that I have below?

^([a-zA-Z0-9-]+)$

Try `^(?!.*home)([a-zA-Z0-9-]+)$`. It is not quite clear where `home` can appear in your string, and if you need to match it as a whole path part or word or just as a part of a string. – Wiktor Stribiżew Jan 25 '17 at 10:05
Like this: mysite.com/home – ShoeLace1291 Jan 25 '17 at 10:09
@WiktorStribizew That worked perfectly! – ShoeLace1291 Jan 25 '17 at 10:10

And if you have mysite.com/somepath/here-is-your-home? The regex I shared will also "exclude" this path. Is it OK? – Wiktor Stribiżew Jan 25 '17 at 10:12
