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. Do not 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.

Based on this topic: How are users identified? (when adding/transfer existent users)


Install phpBB WordPress domain/subdomain integration: how to hints

phpBB installed at plugins.w3tasks.com
WP installed at w3tasks.com

To install wp_w3all on a subdomain/domain i have use the custom config.php option, as we are here in subdomain installation. I’ve see it was not working about connession. It was failing because, the custom wp_w3all phpBB config.php file, was lacking the follow setting, which was REQUIRED to connect on my/this server correctly (as on plesk config setting i had set allow only from localhost connections), so:

(this my setting, check your host/port)

So, on phpBB ACP cookie setting:
i had as default phpBB cookie value:
i’ve modify it to:
I have also set admin of phpBB with same email of WP.
SO I HAVE CLEAN COOKIES on browser, and login successfully.
All working nice.

(For security reasons by the way, should be not good practice to have an administrator named admin: commonly it should be removed and replaced by someone not so clear as one named admin, if no other security measures applied on wp).

The above suppose you have follow also steps about phpBB WordPress integration here:

phpBB images and .htaccess:
how to set phpBB avatars images available over all your domain

On Apache server, the default phpBB .htaccess file in phpBB/images/avatars/upload folder, by default, is setup to deny access to images files if these are requested by an external resource, or the call to images files are done outside the phpBB installation folder.

So, to get working WP_w3all avatar option, it is required to edit the default .htaccess file of phpBB that reside inside phpBB/images/avatars/upload folder, setting it to serve images for requests that are done within your domain(s) or localhost test server. You could also remove or disable the .htaccess, but you are noticed that in this case, images on this folder if linked from external sites, are accessible.

The default phpBB/images/avatars/upload/.htaccess file look like this:

so you’ll edit it, allowing instead requests that are done from your host with something like this (this first example is for localhost):

this example instead is for an online site:

on Unix/Linux systems, you may also check for correct folder chmod in case the above still not let you to get available avatars, from the phpBB avatar’s folder.

WP_w3all manual setup phpBB
config.php and path setting how to

To setup a custom phpBB config.php file and setup the relative absolute path setting to it on WP_w3all admin config page, follow these steps:

Open folder:
inside you’ll find the folder:
wp-w3all-config that contain two files, config.php and .htaccess.
COPY the entire FOLDER wp-w3all-config AS IS and paste it or upload it via ftp in:
so you’ll have:
with a text editor open the file config.php contained into folder
and follow hints inside: you just need to add values, the same as are on your phpBB root config.php file, if you do not know how to fill required fields. Remember to un-comment, removing the pre pending // chars in front the very last line on your custom config.php file, as explained on inline file hints, or even if on Wp_w3all config page the path value that need to point to this file will be correct, the plugin will not result active.
Hint: memo that you can so also deactivate the WP_w3all plugin safely any time, by opening this file and commenting out this line (or you could do it for testing purpose by setting wrong the path to this file, into WP_w3all admin config page).

Now setup the Path value on WP_w3all admin config page that need to point to this config.php file.
Example: /web/htdocs/home/wp-content/plugins/wp-w3all-config
For help on how to know/setup your correct path value, refer to this post:
How to find and set correct absolute path

WP_w3all has been installed. Remember to transfer old existent WordPress users into phpBB when integration start. This is a MANDATORY step. Configure options and widgets. Read more FAQ and hints here:

Embed phpBB into WordPress template:
iframe responsive how to

This is the old  iframe procedure.
New iframe procedure and code is available here:

PAGE HELP – UPDATED on 19 Sept 2018
(related views/page-forum.php – updated on 27 Sep 2017)

Iframe resizer library by:

wp_w3all responsive iframe procedure

After you’ve built/created the WP forum template page via
WP_w3all phpBB embedded on WordPress Template
option on WP_w3all admin config page, and the blank page on WordPress Admin -> Pages -> Add New, titled the same of  created wp_w3all template page, so forum or board etc…, to complete the procedure and get the responsive iframe height for the embedded phpBB into WordPress template page you need:

Open with a text editor your phpBB template file overall_footer.html

and just before the closing </body> tag, add this code (do not select lines numbers column on copied code):


after you pasted this code into phpBB overall_footer.html edit the second line on added code:

change localhost to fit your domain name (example axew3.com), do NOT add http(s):// OR the point in front, just add
yourdomain.com or leave localhost if on localhost. If phpBB is at subdomain.domain.com, add domain.com as value
(MANDATORY!) or resizer won’t work
now check

in the code you added (last line): this should correctly point to the  iframeResizer.contentWindow.min.js file that you’ll go to add into phpBB root folder. You need to use the absolute URL (use http or https as needed, and adjust the url to fit your needs)
(MANDATORY!) or resizer won’t work

AFTER EDITED, save and load the modified overall_footer.html into your phpBB style folder, overwriting the default one, and so

load through ftp on the phpBB root folder (or copy/paste), the file
that is contained inside folder

After this, phpBB require to recompile the template, or modifications to  template files not affect (to overall_footer.html in this case). Open phpBB ACP, and so under:

Server Configuration -> Load settings -> Recompile stale style components  set to YES and save. Load one time a phpBB full forum page. So return to ACP and reset to NO, save. This step is needed one time to load the template modifications on phpBB (and any time you edit a phpBB template file to for modifications take effect), but this option should be ever set to NO into an online/production site to save server resources. It is normally set to yes only for testing/devel purpose or to apply modifications on phpBB  templates files.

If you want phpBB email notification links to point to iframe, follow this step about htaccess:

phpBB htaccess for phpBB notification email to point WP forum page (1.6.9>)

to activate the rewrite right click/copy links on iframe, to point to iframe, activate the related code removing the two lines:

/* remove this line to activate htaccess trick
*/ //remove this line to activate htaccess trick

NOTE: to get the iframe to be responsive for ACP phpBB admin panel, read this post.

If any question, use the forum here or at wordpress.org wp-w3all-phpBB

Configure phpBB
to set cookie available all over domain

To configure phpBB to set cookie to be available all over the domain (and subdomains), you need to setup cookie domain and path into phpBB ACP in this way:

Open phpBB Admin Control Panel, go under

Server configuration -> Cookie settings
Cookie domain value should be set like the domain name is: so if your site domain is as in this example, axew3.com, the correct value to set is:
in this way cookies become available all over axew3.com and any subdomain like mysubdomain.axew3.com.

Cookie path setting should be set as a single fraction slash: /
Save settings.
If changed cookie setting in phpBB in this way, logout, CLEAN cookies from browser, and re-login.

if on localhost, may leave the value as is. If on subdomain, like myforum.mysite.com, set it as above using only domain name mysite.com)

If you have change these values, Logout, CLEAN cookies from browser, and re-login.

( Older browsers still implementing the deprecated » RFC 2109 may require a leading . (dot) to match all subdomains, so .mysite.com )

NOTE: if cookie setting has been changed to be available over all domain because it was not, then all phpBB users may need to re-login using new board’s cookie settings: in this case, you may would like to force all phpBB users to re-login in case they saved their session cookie with a ‘remember me login’. This can be done by accessing phpBB ACP main page: check for option
Purge all sessions
Purge all sessions. This will log out all users by truncating the session table.
Click the Run now button.
Be sure that the cookie setting is correct before to execute these steps, or you’ll be logged out by your board until you’ll not reset to the correct cookie domain!

mysite.co.uk OR mysubdomain.mysite.co.uk, correct setting will be: mysite.co.uk (while if you are on a subdomain hosting plan like mydomain.myhostingprovider.com, than the setting will be mydomain.myhostingprovider.com, but this is a more rare case)

The following help hint hint here is obsolete as latest patched wp_w3all 1.8.9 version.

from latest patched  1.8.9 plugin version it is just required that the phpBB cookie setting is set correctly to be available over all the domain: then the plugin code will setup correctly at any time the same value for himself in WordPress. The follow is here for reference, but not more useful or needed in effect.

If still in trouble with cookie setting (you can’t login with user via WP login after path to config.php has been setup) follow this step:

just in case, this is the way to fix any problem:

open file wp_w3all.php and +- on top you’ll see these lines:

change the second line, removing the two // in front, so the above become something like (change .domain.com with your domain name)

if on localhost, setup as ‘localhost’
save/overwrite the wp_w3all.php file, then test the login. If all ok, then the cookie setting for the plugin is ok now. Re-add the two // slashes in front of the edited line on wp_w3all.php to deactivate it (or remove the line), and save/overwrite the file wp_w3all.php.

Hint/memo: if an user login via phpBB and the cookie setting setup in phpBB ACP is to release the cookie to be valid over all the domain (as above explained), then also if the cookie setting of the plugin is wrong, the user will be correctly auto logged in WordPress when will visits WP side as logged phpBB user, because a valid phpBB cookie to check against will be found.

That’s all here!
