WP_w3all for WordPress MS MU (Multisite, Multiuser network installations)

Configure WP_w3all on WordPress MS MU

WP_w3all plugin from 2.0.2 – WordPress MU MS . The plugin can be also network activated, but the linked phpBB on each subsite, need to be the same (same path and same url setting value). If the plugin is network activated, it is mandatory that the sub admin or super admin, setup/configure into (each) subsite the same config of the main site for the integration plugin. Users that register in phpBB (if you allow this in phpBB) are added as users only into the FIRST WP site (or subsite) where users will login or that they will visits while coming already logged in into phpBB. *But you could use a plugin to add coming phpBB logged users, into each or just few WordPress site/subsites they visits, see more below.

OPEN wp-config.php file:

search for line (value wp_ can be maybe different):

$table_prefix = 'wp_';

1	$table_prefix = 'wp_';

immediately after ADD:

define( 'WPW3ALL_MAIN_DBPREFIX', $table_prefix );

1	define( 'WPW3ALL_MAIN_DBPREFIX', $table_prefix );

NOTE since 2.7.9>

If you want the phpBB users additions in WordPress allowing all default WP characters for the WordPress usernames, add the follow:

define( 'WPW3ALL_USE_DEFAULT_WP_UCHARS', true );

1	define( 'WPW3ALL_USE_DEFAULT_WP_UCHARS', true );

adding the above, allowed characters for WordPress usernames that are added in WordPress from phpBB, becomes:

-0-9A-Za-z _.@

1	-0-9A-Za-z _.@

so alphanumeric characters (letters and numbers) spaces, underscores, hyphens, periods, and @

The default WP MUMS normally and by default only allow the range

0-9A-Za-z

0-9A-Za-z

so only alphanumeric characters

BEWARE that it is NOT possible to link different phpBB installations on same installation network, the integration in this state lead to unpredictable results! It is NOT possible to link a different phpBB into WP network subsites with actual code.
Setup into sub-sites, if the plugin is network activated, same path and url in WP_w3all config, with same values of main site.

*Hint: you could use a plugin to add coming phpBB logged users, into each WordPress they visits, or just to few, and with several different features: search for Join My Multisite plugin at WordPress plugins directory.

NOTE: WP_w3all phpBB integration plugin when an user is deleted in WordPress (so it become deactivated in phpBB, and then you may go to delete this user in phpBB) also clean up from signup table in WordPress this user. This is necessary for compatibility (as the code is) with the phpBB integration to avoid that another user register with same email into phpBB (if you allow users to register also on phpBB side, and you have may also deleted this user in phpBB) while the user has been deleted in WP, but his email/username still stored into WP database signups table.

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:

RewriteRule ^(.*)$ app.php [QSA,L]

1	RewriteRule ^(.*)$ app.php [QSA,L]

just below add the follow:

#p reserved in WP
RewriteCond %{QUERY_STRING} ^(.*)(iframe=true&)(.*)(p=)([0-9]+)(.*)?$
RewriteRule . /yourwp/index.php/forum/?%3post_id=%5%6 [R,L]
#all others
RewriteCond %{QUERY_STRING} ^(.*)(iframe=true)(.*)$
RewriteRule . /yourwp/index.php/forum/?%3 [R,L]

#p reserved in WP

RewriteCond %{QUERY_STRING} ^(.*)(iframe=true&)(.*)(p=)([0-9]+)(.*)?$

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

#all others

RewriteCond %{QUERY_STRING} ^(.*)(iframe=true)(.*)$

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

Change on lines

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

and

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:

#p reserved in WP
RewriteCond %{QUERY_STRING} ^(.*)(iframe=true&)(.*)(p=)([0-9]+)(.*)?$
RewriteRule . /w3/index.php/forum/?%3post_id=%5%6 [R,L]
#all others
RewriteCond %{QUERY_STRING} ^(.*)(iframe=true)(.*)$
RewriteRule . /w3/index.php/forum/?%3 [R,L]

#p reserved in WP

RewriteCond %{QUERY_STRING} ^(.*)(iframe=true&)(.*)(p=)([0-9]+)(.*)?$

RewriteRule . /w3/index.php/forum/?%3post_id=%5%6 [R,L]

#all others

RewriteCond %{QUERY_STRING} ^(.*)(iframe=true)(.*)$

RewriteRule . /w3/index.php/forum/?%3 [R,L]

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):

'U_VIEW_MESSAGE' => generate_board_url() . '/ucp.' . $this->php_ext . "?i=pm&mode=view&p={$this->item_id}",

1	'U_VIEW_MESSAGE' => generate_board_url() . '/ucp.' . $this->php_ext . "?i=pm&mode=view&p={$this->item_id}",

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

'U_VIEW_MESSAGE' => generate_board_url() . '/ucp.' . $this->php_ext . "?iframe=true&i=pm&mode=view&p={$this->item_id}",

1	'U_VIEW_MESSAGE' => generate_board_url() . '/ucp.' . $this->php_ext . "?iframe=true&i=pm&mode=view&p={$this->item_id}",

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.

Solutions:

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)

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:

<Files *>
	Order Allow,Deny
	Deny from All
</Files>

Order Allow,Deny

Deny from All

</Files>

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

<Files *>
	Order deny,allow
	Deny from All
	Allow from 127.0.0.1
        Allow from ::1
</Files>

Order deny,allow

Deny from All

Allow from 127.0.0.1

Allow from ::1

</Files>

this example instead is for an online site:

<Files *>
Order deny,allow
Deny from all
Allow from axew3.com
</Files>

Order deny,allow

Deny from all

Allow from axew3.com

</Files>

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:
wp-content/plugins/wp-w3all-phpbb-integration/addons
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:
wp-content/plugins
so you’ll have:
wp-content/plugins/wp-w3all-config
with a text editor open the file config.php contained into folder
wp-content/plugins/wp-w3all-config
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.

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 activated. Remember to transfer, if there are, old existent WordPress users into phpBB when integration start. This is a MANDATORY step. Configure options and widgets. Read more FAQ and hints here:
https://www.axew3.com/w3/cms-plugins-scripts/wordpress-plugins-scripts-docs/wordpress-phpbb-integration/

Hint: remember that you can completely deactivate the WP_w3all plugin safely any time, by opening this file and commenting out the last line in this way:

// @define('PHPBB_INSTALLED', true);

1	// @define('PHPBB_INSTALLED', true);

1	document.domain = 'localhost'; // THIS IS MANDATORY! Set/Change this value to your domain (example: axew3.com (or leave localhost if on localhost))

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

1	<script type="text/javascript" src="https://www.axew3.com/phpBB/iframeResizer.contentWindow.min.js" defer></script>

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
iframeResizer.contentWindow.min.js
that is contained inside folder
YOURWP/wp-content/plugins/wp-w3all-phpbb-integration/addons/resizer

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

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

phpBB external login redirect
how to – domain, subdomain

To correctly do an external redirect for domain in phpBB 3> it is required to modify/edit a single file in phpBB:

open with text editor /includes/functions.php

search for the function redirect

function redirect($url, $return = false, $disable_cd_check = false)

1	function redirect($url, $return = false, $disable_cd_check = false)

inside this function there is this code:

else if (!empty($url_parts['scheme']) && !empty($url_parts['host']))
{

1 2	else if (!empty($url_parts['scheme']) && !empty($url_parts['host'])) {

just after this two lines, add the follow:

$disable_cd_check = true;

1	$disable_cd_check = true;

save and replace phpBB includes/functions.php.

Consider that this solution not meant to redirect to cross-domains and only able to redirect within the same domain if $disable_cd_check is false (yourdomain.com -> www.yourdomain.com will not work).

Another way on the same function redirect of same file includes/functions.php

search for

function redirect($url, $return = false, $disable_cd_check = false)
{
 global $user, $phpbb_path_helper, $phpbb_dispatcher;

function redirect($url, $return = false, $disable_cd_check = false)

{

global $user, $phpbb_path_helper, $phpbb_dispatcher;

immediately after add the following code:

global $request;
if( $request->variable('mode', '') == 'login' && isset($_POST["redirect"]) ){
$rwp = trim($_POST["redirect"]);
header("Location: $rwp");
exit;
}

global $request;

if( $request->variable('mode', '') == 'login' && isset($_POST["redirect"]) ){

$rwp = trim($_POST["redirect"]);

header("Location: $rwp");

exit;

}

Maybe a little check to this passed redirect url, if it is coming from WordPress side, or within phpBB, or from a needed specific domain to redirect to should be done (may not).

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:
.axew3.com
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: /

Change the cookie
Save settings.
If changed cookie setting in phpBB in this way, logout, CLEAN cookies from browser, and re-login.

NOTE:
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)

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

NOTE: if cookie setting 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)
