Question

We have a site using wordpress and we have discovered that at some point, a bad plugin or user error has added double slashes after the siteurl (for example, http://example.site//category1/ or http://example.site/category1//category2/, etc.

This seems to work but it looks like there aren’t quite enough results.

SELECT id, post_content
FROM `wp_posts`
where post_content
regexp '(href="[^"]*[^:]\/\/[^"]*)'
and post_status  in('draft','publish')
order by id asc

Is there a better way to do this? I don’t want it to match on the double slash that comes after the http:, hence the negative match on the :.

Edit: for clarification, I want to find all posts (the body of a wordpress post/page) that have a url hard-coded into the page that has double slashes, but do not match on the double slashes after the http:.

Regexp should match on the following:
http://example.site//category1/ or http://example.site/category1//category2/ or even http://example.site/category1/category2// or example.site/category1//category2/

But should not match on the following:
http://example.site/category1/ or http://example.site/category1/category2/

Answer 1

Perhaps something like this would work.

SELECT *
FROM wp_posts
WHERE CASE WHEN instr(post_content,'http://') > 0 THEN 
  substring(post_content,7) regexp '\/\/'
ELSE
  post_content regexp '\/\/'
END

And here is the SQL Fiddle.

Good luck.
