phpBB3 SEO - redirect to xenForo

Case

Active member

Hi guys

Thinking of converting my phpBB3 site to xenForo. I currently run phpBB3 with the SEO mod so my site URL's look like this...

forum/topic-title-t1234.html
forum/forum-name-f1.html

Any idea of the changes I need to make to my .htaccess file to get everything redirecting to the correct xenForo equivalent URL?

I did see this thread http://xenforo.com/community/threads/phpbb3-redirection.28094/ but I think that's just for the standard phpBB3 URL's.

Thanks

OK, thanks Jake. When I've grabbed a license, I'll post in there.

Just doing some research first to see how easy the switch will be. All looking good so far. Obviously this is a big concern, need to make sure all current content isn't lost in the search engines.

Cheers.

In .htaccess find
Code:
RewriteRule ^.*$ index.php [NC,L]
and add before it:
Code:
RewriteRule ^(.*)\.html html.php [NC,L]
That will redirect all .html links to html.php

Then create html.php, put something like this in it:
Code:
<?php
 
function phpbb_redirect($url)
{
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: ' . $url);
    exit;
}

function redirect_html()
{
    if (!isset($_SERVER['REQUEST_URI']))
    {
        return;
    }
    $url = explode('/', $_SERVER['REQUEST_URI']);
    $url = explode('.', array_pop($url));
    if (array_pop($url) != 'html')
    {
        return;
    }
    $url = explode('-', array_pop($url));

    $url = array_pop($url);
    $type = substr($url, 0, 1);
    $id = intval(substr($url, 1));
    if (!$id) return;
    
    switch ($type)
    {
        case 't':
            phpbb_redirect('index.php?threads/' . $id . '/');
        case 'f':
            phpbb_redirect('index.php?forums/' . $id . '/');
    }
}

redirect_html();
include('index.php');
I haven't tested that code.

I am also looking to do a phpBB SEO redirect to XF.

Case, have you tried out Arty's advice?
If you can provide examples of old and new URLs then I can make some rewriterules for you. Also, did you enable the import option to preserve the source ids or not?

If you can provide examples of old and new URLs then I can make some rewriterules for you.
Old: debate-forum-f21/race-t2849-20.html

I haven't done the import yet (scheduled in 9 hours), so I am not sure.

Also, did you enable the import option to preserve the source ids or not?
Would not enabling them cause too much trouble? I was hoping to "reset" the forum/topic numbering.

Thank you for all your help, Jake.

OK, I completed the transfer with the preserved source IDs.

I have this bit in my htaccess, taking care of the regular phpBB URL redirects:
Code:
        RewriteCond %{QUERY_STRING} (^|&)t=([0-9]+)(&|$) [NC]
        RewriteRule ^viewtopic\.php$ /threads/%2? [L,R=301,NC]
        RewriteCond %{QUERY_STRING} (^|&)p=([0-9]+)(&|$) [NC]
        RewriteRule ^viewtopic\.php$ /posts/%2? [L,R=301,NC]
        RewriteCond %{QUERY_STRING} f=(\d+)$ [NC]
        RewriteRule ^viewforum\.php$ /forums/%1 [L,R=301,NC]
Old phpBB SEO URLs:
debate-forum-f21/
debate-forum-f21/race-t2849-20.html

New XF URLs:
forums/debate-forum.21/
threads/race.2849/

My brain is a bit fried after sitting on the transfer for 5 hours. Is Arty's suggestion the best option in my case?

Hi there,

i modified the script by @Arty to fit the needs for proper redirection of the paginated pages. The main problem is that XenForo uses 20 posts per page where phpbb 3 shows only 10. That means a phpbb Url like

building-a-proper-motion-seat-base-for-scn5-s-t2216-20.html
which is the page 3 of the phpbb3 forum
must be translated to a XenForo URL like:
building-a-proper-motion-seat-base-for-scn5s.2216/page-2

Notice, that the XenForo link must be page 2;)

Hope you it helps someone with similar problems.
Btw. It´s quick `n dirty but working!

PHP:
<?php
function phpbb_redirect($url)
{
  
    //exit;
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: ' . $url);
    exit;
}

function redirect_html()
{
    if (!isset($_SERVER['REQUEST_URI']))
    {
        return;
    }
    $url = explode('/', $_SERVER['REQUEST_URI']);
    $url = explode('.', array_pop($url));
    if (array_pop($url) != 'html')
    {
        return;
    }
    $url = explode('-', array_pop($url));

    $url = array_pop($url);
    $type = substr($url, 0, 1);
  
    /* get the next to last string */
    if (is_numeric($type) == true && $type) { // There is pagination like are-you-a-new-member-introduce-here-t1737-10.html
        $url_page = explode('/', $_SERVER['REQUEST_URI']);
        $url_page = explode('-', array_pop($url_page));
      
        $typestring = array_slice($url_page, count($url_page)-2, 1);
        $typestring_check = $typestring[0];

        //echo $url ."<br>";
        //echo $typestring_check . "<br>";
        //echo substr($typestring_check, 0,1) . "<br>";
        $type = substr($typestring_check, 0,1);
        //echo $type . "<br>";
        //echo $type;
        // if last string is int, its paginated
        $id = intval(substr($typestring_check, 1));
        $page = $url/10; //Division durch 10
      
        //echo $page;
        switch ($type)
        {  
            case 't':
                if ($id == 1){
                phpbb_redirect('index.php?threads/' . $id . '/'); //redirect to first page
                }else{
                phpbb_redirect('index.php?threads/' . $id . '/page-' . $page); //redirect to paginated page
                }
            case 'f':
                phpbb_redirect('index.php?forums/' . $id . '/');
        }
    } else { // No pagination (Maybe first page of the thread) like like are-you-a-new-member-introduce-here-t1737.html
  
        $type = substr($url, 0, 1);
        $id = substr ($url, 1);
      
        //echo $id . "<br>";
        //echo $type;
        switch ($type)
        {  
            case 't':
                phpbb_redirect('index.php?threads/' . $id . '/');
              
            case 'f':
                phpbb_redirect('index.php?forums/' . $id . '/');
        }
  
    }
}
redirect_html();
include('index.php');
