Multiple Forums using a single user table

This was originaly done in 3.0.9 by westpointer you can view that thread here

This Modification is for VB3.5.4 This is not supported but I will give as much help as I possible can.

I have this working now on 2 sites

The main site is http://forums.everything2stroke.com

Slave sites are
http://forums.everythingmx.com
and
http://forums.everythingduners.com

After a successfull install of this modification your sites will share User, PM, and sesson data.

This thread will detail how to have a single login for multiple forums. It makes the following assumptions:

• A valid vbulletin license exists for each install
• All forums will be on the same server
• One database will contain all the tables

A valid vbulletin license exists for each install


Follow these steps

1.) Download your new copy of VB that contains a seperate license key
2.) Go to /includes/config.php.new rename the file to config.php and make necessary changes to the file. See VB Directions. Make sure this code has a different setting than the master site for table prefix.

PHP Code:

 //          ****** TABLE PREFIX ******
 //          Prefix that your vBulletin tables have in the database.
$config['Database']['tableprefix'] = ''; 


3.) Run the vb install from the new directory (/www/new_forums/install/install.php)

4.) During the install, be sure NOT to empty the tables. If you have any doubt about what this means, stop NOW! If you empty the tables, you will lose all of your existing data from a prior install!

5.) Download all files and directories to your PC from the new install location.

6.) You will need a tool to do a mass Search and replace on all files. I use WildEdit. Here is what you will do using a tool like Wild Edit.

• Search for [" . TABLE_PREFIX . "user] Replace with [" . "vb3_user] where "vb3_" is the prefix to your master site. 110 Files modified 599 Total changes made
• Search for [" . TABLE_PREFIX . "strikes] Replace with [" . "vb3_strikes] where "vb3_" is the prefix to your master site 4 Files modified 8 Total changes made
• Search for [" . TABLE_PREFIX . "pm] Replace with [" . "vb3_pm] where "vb3_" is the prefix to your master site 16 Files modified 77 Total changes made
• Search for [" . TABLE_PREFIX . "session] Replace with [" . "vb3_session] where "vb3_" is the prefix to your master site 20 Files modified 31 Total changes made

Now to modify some of the code.

In /include/class_dm.php

Search for:

PHP Code:

 function fetch_insert_sql($tableprefix, $table)

            { 


Add below change vb3_ to your master site prefix:

PHP Code:

if ($table == "vb3_pmtext")

            {

                        $sql = "INSERT INTO {$table}\r\n\t(" . implode(', ', array_keys($this->$table)) . 


")\r\nVALUES\r\n\t(";

            

            }

            else 


Go to /include/class_dm_pm.php

Search for:

PHP Code:

var $table = 'pmtext'; 


Replace with making vb3_ the prefix to your master site:

PHP Code:

var $table = 'vb3_pmtext'; 


Search for:

PHP Code:

$pmtextid = ($this->existing['pmtextid'] ? $this->existing['pmtextid'] : $this->pmtext['pmtextid']); 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

$pmtextid = ($this->existing['pmtextid'] ? $this->existing['pmtextid'] : $this->vb3_pmtext['pmtextid']); 


Search for:

PHP Code:

$this->dbobject->query_write("INSERT INTO " . TABLE_PREFIX . "pm (pmtextid, userid) VALUES ($pmtextid, $user[userid])"); 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

$this->dbobject->query_write("INSERT INTO " . "vb3_pm (pmtextid, userid) VALUES ($pmtextid, $user[userid])"); 


Search for:

PHP Code:

" . $this->dbobject->escape_string($user['username']) . "', '" . $this->dbobject->escape_string($this->pmtext['title']) . 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

" . $this->dbobject->escape_string($user['username']) . "', '" . $this->dbobject->escape_string($this->vb3_pmtext['title']) . 


Go to /include/class_dm_user.php

Search for:

PHP Code:

$return = $this->db_update(TABLE_PREFIX, 'user', $this->condition, $doquery, $delayed); 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

$return = $this->db_update('vb3_', 'user', $this->condition, $doquery, $delayed); 


Search for:

PHP Code:

$this->db_update(TABLE_PREFIX, 'userfield',     $this->condition, $doquery, $delayed); 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

$this->db_update('vb3_', 'userfield',     $this->condition, $doquery, $delayed); 


Search for:

PHP Code:

$this->db_update(TABLE_PREFIX, 'usertextfield', $this->condition, $doquery, $delayed); 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

$this->db_update('vb3_', 'usertextfield', $this->condition, $doquery, $delayed); 


Search for:

PHP Code:

if ($return = $this->db_insert(TABLE_PREFIX, 'user', $doquery)) 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

if ($return = $this->db_insert('vb3_', 'user', $doquery)) 


Search for:

PHP Code:

$this->db_insert(TABLE_PREFIX, 'userfield',     $doquery); 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

$this->db_insert('vb3_', 'userfield',     $doquery); 


Search for:

PHP Code:

$this->db_insert(TABLE_PREFIX, 'usertextfield', $doquery); 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

$this->db_insert('vb3_', 'usertextfield', $doquery); 


Search for:

PHP Code:

DELETE FROM " . TABLE_PREFIX . "session 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

DELETE FROM ?.?vb3_session 


Search for:

PHP Code:

INSERT INTO " . TABLE_PREFIX . "passwordhistory (userid, password, passworddate) 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

INSERT INTO " . "vb3_passwordhistory (userid, password, passworddate) 


Search for:

PHP Code:

 UPDATE " . TABLE_PREFIX . "session SET 


Replace with where vb3_ is the prefix to your master site:

PHP Code:

   UPDATE ?.?vb3_session SET 


That is all the code modification.


The only other item I did is remove a couple cron jobs.

Go into Scheduled tasks then to Scheduled Task Manager

Delete the following CRON jobs from the Slave Site

User Promotions*
Birthdays
Activation Reminder Email

This will eliminate members getting emails from the primary and secondary sites
*not sure if this will duplicate efforts between primary and secondary sites I have it running on both sites still waiting to see if it causes any issues.


Please post here if you have any problems and questions I will try my best to keep up with everyone to help you through this. Once you get the code done the first time you can just do a mass search and replace on your license code and you can be up and running in minutes with a new site.

This is my first major modification so I hope I posted this all correct, again Thanks to Westpointer for his original work without his post this would not have been possible.

Thanks

UPDATE:

Please make this changes it will allow you to make changes to usergroups in the subscription section and when editing a user.

admincp/adminfunctions.php
Search for

PHP Code:

                $result = $vbulletin->db->query_read("SELECT title, $tableid FROM " . TABLE_PREFIX . "$tablename $wherecondition ORDER BY title"); 


Replace with

PHP Code:

if ($tablename == "usergroup")
                {
                $result = $vbulletin->db->query_read("SELECT title, $tableid FROM " . "vb3_$tablename $wherecondition ORDER BY title");
                }
                else
                {
                $result = $vbulletin->db->query_read("SELECT title, $tableid FROM " . TABLE_PREFIX . "$tablename $wherecondition ORDER BY title");
                }

Posts and Threads are seperate between sites only User, PM, and Session data is shared between sites.

This is not to say it would not be possible. It would probably just take some modification to the search.php so that it looks that the 2 forums you want it to display.

Interesting I might look into this if I find time

That'd be cool, especially since their's so many user profile mods making interaction between people greater.

I was drafting a similar mod before 3.5, then realized that 3.5 was suppose to have a similar feature (if I'm not mistaken), and decided to stop working on it... its too bad that the feature never made it to live...

[e2s]

I don't recall any supposed feature for 3.5. I know they have teh Master and Slave Database but I really don't know that much about it.

[e2s]

Thank you.

[bonjurkes]

ok, it sounds a great idea but i have questions about it

2-) will i use same database with my master board?

6-) i will use vb3_ for my slave board, and the prefix for my master board is . (default one) must i do that mass change that told at step 6 ?

[SaN-DeeP]

wonderful addon, I will have to test this before going for some live implementation

[thumbsucker]

Ok, so having a slave forum means that you share the same user DB.

But I assume the slave and master forums can have different discussion sections?

How would changing user groups on the slave affect the master? All changes are made essentially simultanously on both?

[utw-Mephisto]

What about the file edits when I don't use a prefix on the master , like

Replace with where vb3_ is the prefix to your master site:
$this->db_insert('vb3_', 'usertextfield', $doquery);

Since I don't use prefixes for the master, would I change it to :

$this->db_insert('.', 'usertextfield', $doquery);

???

Also :

Go to /include/class_dm_pm.php

Search for : var $table = 'pmtext';

change to : var $table = 'vb3_pmtext';

But once again, my master does not have a prefix ... would I have to change it to

change to : var $table = '._pmtext';
