[Solved] 301 redirect help with regex needed after wp embed

edited March 2011 in Vanilla 2.0 - 2.8
I am getting a TON of bots and users with 404 errors after embeding my forums.

I used the same directory name but the # in the path is what is breaking it.

eg: it went from ->
to ->

I thought maybe adding a redirect to my htaccess may fix it but I am not the best at regex. Does this look right?

    I figured out how to handle this in WordPress with the Redirection Plugin
    I'll share what I did in case anyone else runs into it

    First - I saw some old phpBB entries coming in with the pattern like this (which I was using before porting over to vanilla)

    To fix old phpbb links to new vanilla links
    * Original Source -
    * Target -

    Regex used to redirect it
    - Source - /forum/viewtopic(.*)t=(\d*)&(.*) - Target - /forum/#/discussion/$2/

    I added a second one to catch those that don't have post start info (no start)
    - Source - /forum/viewtopic(.*)t=(\d*) - Target - /forum/#/discussion/$2/

    My pre to post embed vanilla links (with the #) I used this
    - Source - /forum/discussion/(.*) - Target - /forum/#/discussion/$1

    And for direct comment links in vanilla
    - Source - /forum/discussion/comment/(.*) - Target - /forum/#/discussion/comment/$1

    And for profile links in vanilla
    - Source - /forum/profile/(.*) - Target - /forum/#/profile/$1

    Anyway, it may give you a starting point if you are hitting this sort of thing.

    The ones I listed above & addressed were showing up as 404 errors after embedding (mostly from search engines and old incoming links) but this fixed it.

    If there is a more graceful pattern or better way to do it I welcome it :)

  • I edited the Vanilla Forums Wordpress plugin file vanilla-forums/widgets.php and modified the line

    $link_url = vf_get_link_url($options);

    to hard code my path.

    Graceful, no. Easy, yes.
  • Nice :)

    The majority of the links I had to correct were from external sources so I the redirect worked great for me. While I was in there I adjusted some internal ones based on the patterns as well.
