WP_w3all .htaccess and Javascript for phpBB: rewrite URLs to point iframe how to (Spiders friendly)

Open .htaccess file of your phpBB root folder, search for this line:

just below add the follow:

Change on lines

RewriteRule . /yourwp/index.php/forum/?%3post_id=%5%6 [R,L]


RewriteRule . /yourwp/index.php/forum/?%3 [R,L]

the relative iframe URL that need to point to your correct WP forum page (leave index.php in place).

To help understand, this is the correct .htaccess code for this online working example:

WP page forum URL (that contain and display the iframe in this case): https://www.axew3.com/w3/forum/

Resulting .htaccess code based on this will be:


To complete the redirect flow to the iframe phpBB, embedded into WP page, for phpBB email notification messages links to point to iframe follow also with these two steps (get ready files for phpBB 3.2 on bottom of this page):

For email notification links that you want to redirect to iframe forum page of WP, assuming we point to three main behaviors we are interested in, which are for example PM notifications, New posts and Topics on forum, we need to change so 3 phpBB files in this way:

open folder  your-phpBB/phpBB/notification/type

on this folder, as working example, we go to open and so modify the following files:

pm.php, post.php, topic.php

on each file, you’ll find very similar code like this (in pm.php there is only one to change, on topic.php and post.php there are 4 or 5: avoid to apply this edit to the last one string on post.php and topic.php):

you should change these urls, adding iframe=true& on each line, exactly after the ? char, like this:

How are users identified when you add/transfer existent user
integration of same username/email users

Problem: i have WordPress users and I have phpbb users, they have different usernames but the same email addresses.


user A into phpBB with email C
user B into WP with email C

user A into phpBB come to try to login WP: NOT added can’t login WP side.

If you use the transfer process of WP users into phpBB:

user A Same above.
user B transferred into phpBB, B now can login into both phpBB and WP.
You’ll have two users into phpBB with same email, which is possible as option into phpBB.

You can also merge posts/users into one user in this way:

Change email to the user B in WP.
Login with the phpBB user A into WP, that will be added, as no same email found.
Now delete user B in WP, and retain posts assigning to A.

Result: an unique user, with all his posts on both phpBB and WP.

NOTE: This is just to give an idea on how to resolve common problems about an integration with pre existent users in phpBB that may have same email. But there are several more possibilities: in phpBB ACP there are many options to manage users and posts, and combining these and from the above, you should get the way to resolve any possible scenario.
