I have the following 2 redirects active:

-> /tutorials/android/$1/


-> /tutorials/android/$1/

The first one has a higher position, so the second will only be executed if the first one didn't apply. This works if there is something in the placeholders, i.e. /code-examples/page1 leads to /tutorials/android/page1.

The problems occur when the placeholders are empty. Just /code-examples or /code-examples/android WITHOUT the trailing slash leads to 404. With the trailing slash, I can see that it adds a second slash at the end, which results in /tutorials/android//.

How can I get the redirects to work properly with and without something in the placeholders?

    Your code can be combined: /code-examples(?:/android|)(?:/?(.*)|\b) And the problem with your REGEX is because it's "requiring" the / (slash) at the end. Btw, this question would have probably been better asked on Stack Overflow.

  • Thank you! Will the regex you posted solve my problem? Looks hella complicated Oct 25, 2018 at 21:19
  • And I added the redirects with the Redirection plugin. I am a noob. Oct 25, 2018 at 21:19
  • @FlorianWalther Yes, it will. Check my answer and let me know.

  • The problem with your RegEx patterns:


    is that they only match when the ending slash (/) is present in the URL; e.g.:

    # Example 1: $1 is 'page1'
    # Example 2: $1 is '' (empty)
    # Example 3
    # No matches because the ending / is not present.

    where the "placeholder" (i.e. (.*)) matches the page1 in the first example, and '' (i.e. empty string) in the second example.

  • To make these work:


    you can use (?:/?(.*)|\b) instead of /(.*), like so:

  • But since you redirect to the same URL (/tutorials/android/$1/), you can combine those RegEx patterns like so:


    where /code-examples(?:/android|) matches either /code-examples or /code-examples/android.

I added the redirects with the Redirection plugin.

I suppose you have something like this on the Tools → Redirection → Redirects page (in wp-admin):

Now with the combined RegEx pattern, delete the second Redirect and edit the first one like so:

Note: For the Type and Group settings, just use your existing setup.


  • You're welcome, I'm glad it helped you. :)
