I'm trying to set up a custom 404 page using the 404_override option. Trouble is, I have a route set up as (:any) which apparently completely breaks 404_override. If I remove the (:any) rule, it works fine. So, I need to eliminate my (:any) call and instead be specific about what I want for that rule, the problem is that regex doesn't seem to work very well.
Basically I just need to match 3 digits, followed by a dash, then anything.
What I have:
Code:
$route['^\d{3}-(.*)$'] = 'product/index/$1';I've also tried:
Code:
$route['(:num)-(:any)'] = 'product/index/$1';Which works great on regexpal, but, not on CI. My regex is very rusty so if anyone has any suggestions I'd greatly appreciate it.

Aha! It worked but was then only bringing in the

it is only bringing in the second half because of the parenthesis.
([0-9]{3}-.*) should allow $1 to be used but it would be the same as $0 anyway.

and unless you plan on having a uri that looks like
123-
I would use [0-9]{3}-.+
