I am trying to get this regex expression, which works in PHP to work with a multi-url redirect...

I have several urls that need to be redirected to a new, single category.

Old Urls:

/racing-results-news/999-article-title-category-1
/racing-event-news/888-article-title-category-2

New Url:

/event-news-archives/article-title-category-1

This regex works when tested in PHP...

\/(racing-(results|event)-news)(\/\d+)(-)(.*)

replacing ${1} with 'event-news-archives'
replacing ${3} with '/'
replacing ${4} with ${5}

But with the regex expression as my From URL, I'm not getting any hits. So I decided to try and just do separate individual replacements, but I can't get the replacement preg matches to work either.

I tried:

id={preg_match 0}/(racing-results-news|racing-event-news)(/.*){/preg_match}
title={preg_match 1/(racing-results-news|racing-event-news)(/.*){/preg_match}

What am I doing wrong?

Yes!

Okay, stupid question. I use PHP to validate my regex (I'm slow to the pattern matching), so in the From URL I don't need to do all of the normal escaping \/ to match the url?

I think that was part of what I was doing wrong...I now have a single rule to account for multiple categories...

From URL: /racing-(results|event)-news/([0-9]+)-([^\/]+)
To URL: //{siteurl}/events-news-archives/${title}?article_id=${id}
Redirect: 301
Request Only: checked
Decode URL: checked
Placeholders: id={preg_match 2}/\/racing-(results|event)-news\/([0-9]+)-([^\/]+)/i{/preg_match}
title={preg_match 3}/\/racing-(results|event)-news\/([0-9]+)-([^\/]+)/i{/preg_match}

I am now using a Regex editor :-/ It will be faster!

Thank you!!
