Question

I am having an issue using the routes in Codeigniter and my expressions

I have a URL like follows (for a offers page):

www.site.com/company/offers/view/newsarticle/219

and a route like follows:

$route['([a-z0-9_-]+)/offers/view/([a-z0-9]+)/([0-9]+)'] = "offers/view/$1/$2/$3";

I have the above route setup so if should go to the offers controller, and the view function and pass the 3 parameters (company, newsarticle, 219)

It works all fine however if the 4th uri segment contains and ‘-‘ it breaks and gives me a 404 page
eg

This works

www.site.com/company/offers/view/newsarticle/219

But this doesn’t

www.site.com/company/offers/view/news-article/219

Can anyone explain what I’ve done wrong with the expressions? Thanks

Answer 1

Your expression doesn’t allow a hyphen character

([a-z0-9_-]+)/offers/view/([a-z0-9]+)/([0-9]+)

Should be

([a-z0-9_-]+)/offers/view/([a-z0-9\-]+)/([0-9]+)

Note the \- in the [a-z0-9\-]. The \ character escapes the hyphen to tell the expression engine that it’s not a range operator.
