The quick 'n' dirty ultra simple vBulletin SEO hack

Nov 10th, 2005
This is a very quick 'n' simple vBulletin SEO hack. It's easy to apply and it's the one I have been using here on DaniWeb for the past couple of months. I was going to wait until we went vB 3.5 to release it but I might as well do so now ... Disclaimer: This is for vBulletin 3.0.x. It should not be too complicated to port to 3.5 with their hooks system, but I have no experience with 3.5 and therefore don't want to say one way or another. If you use this hack, please link to DaniWeb in your footer. This is a free hack, and it can make or break the traffic to your site. I don't know of any other freely available hacks like this one. Please help us out in exchange for releasing this!

STEP 1: Create an .htaccess file in your forum directory and put the following into it: 
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^getdaily.html$ search.php?do=getdaily [L]
RewriteRule ^getdaily([0-9]+).html$ search.php?do=getdaily&f=$1 [L]
RewriteRule ^unanswered.html$ search.php?do=process&replyless=1&replylimit=0&dontcache=1     [L]
RewriteRule ^unanswered([0-9]+).html$ search.php?do=process&replyless=1&replylimit=0&dontcache=1&forumchoice=$1&childforums=1 [L]
RewriteRule ^forum([0-9]+).html$        forumdisplay.php?f=$1         [L]
RewriteRule ^forum([0-9]+)-([0-9]+)-([a-z]+)-(.*)-([0-9]+)-(.*).html$ forumdisplay.php?f=$1&page=$2&sort=$3&order=$4&pp=$5&daysprune=$6 [L]
RewriteRule ^forum([0-9]+)-(.*)-([a-z]+)-([a-z]+).html$    forumdisplay.php?f=$1&daysprune=$2&order=$3&sort=$4     [L]
RewriteRule ^announcement([0-9]+).html$     announcement.php?f=$1     [L]
RewriteRule ^announcement([0-9]+)-([0-9]+).html$    announcement.php?f=$1&announcementid=$2 [L]
RewriteRule ^thread([0-9]+).html$     showthread.php?t=$1     [L]
RewriteRule ^thread([0-9]+)-([0-9]+).html$    showthread.php?t=$1&page=$2     [L]
RewriteRule ^getnew.html$ search.php?do=getnew [L]
RewriteRule ^getnew([0-9]+).html$ search.php?do=getnew&f=$1 [L]
RewriteRule ^printthread([0-9]+).html$    printthread.php?t=$1     [L]
RewriteRule ^sendthread([0-9]+).html$    sendmessage.php?do=sendtofriend&t=$1 [L]
RewriteRule ^referthread([0-9]+)-([0-9]+).html$ showthread.php?t=$1&referrerid=$2    [L]
RewriteRule ^lastpostinthread([0-9]+).html$ showthread.php?goto=lastpost&t=$1 [L]
RewriteRule ^newpostinthread([0-9]+).html$ showthread.php?goto=newpost&t=$1 [L]
RewriteRule ^nextnewesttothread([0-9]+).html$    showthread.php?t=$1&goto=nextnewest    [L]
RewriteRule ^nextoldesttothread([0-9]+).html$    showthread.php?t=$1&goto=nextoldest    [L]
RewriteRule ^post([0-9]+).html$     showthread.php?p=$1     [L]
RewriteRule ^post([0-9]+)-([0-9]+).html$    showpost.php?p=$1&postcount=$2    [L]
RewriteRule ^post([0-9]+)-([0-9]+)-([0-9]+).html$ showthread.php?p=$1&page=$2&pp=$3    [L]
RewriteRule ^thread([0-9]+)-([a-z]+).html$ showthread.php?mode=$2&t=$1    [L]
RewriteRule ^post([0-9]+)-([a-z]+).html$ showthread.php?p=$1&mode=$2    [L]

STEP 2:

In the includes/functions.php file, below
php Syntax (Toggle Plain Text) 
  1. function print_output($vartext, $sendheader = 1)
  2. {
  3. global $pagestarttime, $query_count, $querytime, $DB_site, $bbuserinfo;
  4. global $vbphrase, $vboptions, $stylevar, $_REQUEST;

in 3.0.7 (in another version of 3.0.x, just put the code below the global declarations in the print_output function) add:

php Syntax (Toggle Plain Text) 
  1.  // do Dani's SEO optimization
  2. global $session;
  3.  
  4. $search_array = array(
  5. '#<a ([^>]*)href' . preg_quote("=\"forumdisplay.php?$session[sessionurl]f=") . '([0-9]+)' . preg_quote("&amp;page=") . '([0-9]+)' . preg_quote("&amp;sort=") . '([a-z]*)' . preg_quote("&amp;order="). '([a-z]*)' . preg_quote("&amp;pp=") . '([0-9]*)' . preg_quote("&amp;daysprune="). '([^"]*)"#',

  74. $vartext = preg_replace($search_array, $replace_array, $vartext);
Please do not duplicate all or part of this code elsewhere. Thanks should go out to Xenon for suggesting to me that I can rewrite URLs from within this function. Thanks!! ... And, please, give credit where credit is due - if you use this hack, please link back.
