PCRE Pattern match to URL

Question

I'm trying to configure a website plugin and need to set a PCRE url pattern for certain pages on my site.

I exclude certain pages using the following patterns successfully.

^/wp-admin/
^/wp-login.php
^/content/

However I also need to exclude pages which are in the following patterns

www.site.com/post_id/post_name/feed/
e.g. www.site.com/345345/myawesomepost/feed/

Where the only static component of the url is /feed/ Would anyone know how to do this using PCRE expressions..?

Answer 1

To exclude urls like this

Format:  www.site.com/post_id/post_name/feed/
Example: www.site.com/345345/myawesomepost/feed/

you might consider the following regular expression:

^(?:\w+\.)+\w+/[0-9]+/\w+/feed/$

Debuggex Demo

Free-spaced:

• ^: Start-of-line anchor
• (?:: [Non-capturing group] of
• \w+\.: One-or-more word-characters, followed by a literal dot (which could also be written as [.]
• )+: One-or-more times
• \w+/: One-or-more word characters followed by a (literal) slash
• [0-9]+/: One-or-more digits, followed by a slash
• \w+/
• feed/: The word "feed" followed by a slash.
• $: End-of-line anchor

Here is an more general and comprehensive answer on using regex to match urls, that may also be of interest.

Answer 2

Domething like this should match

^/.+/feed/

It just matches every url that ends with /feed/

Answer 3

This is what I would use:

/www.+\/feed\//gi

will match:

www.site.com/post_id/post_name/feed/
www.site.com/345345/myawesomepost/feed/

If the urls contain 'http://', you should alter the pattern to:

/http.+\/feed\//gi

The 'i' at the end can be left out if you are sure 'feed' will never contain capital letters.
