如何在http://domain.com/post-type/category/category-name/page/2中找到类别名称，页码

Question

I have an URL formatted like so:

http://domain.com/post-type/category/category-name/page/2

And need to extract only category-name no matter what follows.

For example, in the url:

http://domain.com/projects/category/print/page/2

I only want the word

print

I am trying this regex: category\\/(.+)\\/(?(?=(?:category)\\/)^|(.+))\\/(.+)\\/?$ cobbled together via some searching, but I really am quite confused by Regex.

Note

I am executing this in PHP (in what I think is regex, correct?). At the moment, the Wordpress code is as so: $newrules['projects/category/(.*/?)$'] = 'index.php?post_type=project&project_cat=$matches[1]'; which seems to take the entire URL after projects/category/

Edit

Is it also possible to get the page number as well?

eg: http://domain.com/post-type/category/category-name/page/2

Is it possible to get only category-name and 2 as separate matches?

Answer 1

You've to use an ungreedy matcher .+? the ? behind .+ means ungready and it stops matching after finding the first patterm behind itself. In this case this is /.+ .

/category\/(.+?)\/.+/

Answer 2

你可以试试这个正则表达式。

(?<=http:\/\/domain\.com\/projects\/category\/)([^\/]+)
