Simple vB User login and access control on non vB pages

Hack Description

This is a cutdown version of the user authentication and access control system I use on the non vB pages on my website.

This uses the vB 3.6 login system to log you in and out. It allows you to move between your forums and other pages on your site while remaining logged in.

It allows you to do things such as restrict pages by usergroup, display different content depending on a user being logged in or not.
For example, you can have banner Adds displying to non members only, and/or let members access to specific content.

Ive cut it down to the bare minimum that it needs to work, no fancy stuff such as avatars, PM's, or even formating.

I will try and offer support, but work and family commitments mean I dont have much free time.

This code is a mix of my own, and pieces I have used from other hacks that are floating around.

This script has been confirmed as working on

vB 3.6
vB 3.6.1
vB 3.6.2
vB 3.6.3
vB 3.6.4
vB 3.6.5

Changelog

Version 1.10 (24th April 2007)

Fixed - // in paths bug
Fixed - Javascript warning in some browsers
Fixed - Tidied up some code

Version 1.0 (2nd December 2006)

Very similar to my vB 3.5 version, however logout bug fixed and should be more compatible with other scripts on your page.

Click on Install
If you have this script installed then please click on the install link because;

You will get notified if any security issues are reported.
You will get notified when there are any upgrades to this script
It gives me a warm fuzzy feeling and motivates me to develop more :)

Donations
First of all, to be clear. This script is 100% free.

However if you feel an urge to donate I'm not going to say no. :)

Edit: This usage and trouble shooting guide has been updated as of 24th of April 2007

Usage

The hack is pretty useless without some usage instructions so here they are.

We can use conditionals to hide or display depending on a number of things such as
Logged in or out status,
or restrict to members of a specific usergroup.

We do this by using conditionals in php tags where the normal content of a webpage would go.

If you want something only accessable to a certain usergroup, use this code in your webpage. This example is only visible to members of usergroup 6.

PHP Code:


		
			
<?php

if ($vbulletin->userinfo['usergroupid'] == '6' )

    {

    echo "This is only visible to people in usergroup 6";}

    ?>

You can use a simple variation of this to restrict entire pages to a certain usergroup.
For example,

PHP Code:


		
			
<?php

if ($vbulletin->userinfo['usergroupid'] == '6' )

    {

    echo "Have stuff for here";

             } else {

             echo "You do not have permission for this page"; }

    ?>

You can of course use multiple usergroups by just modifiying the if statement a little.
For example:

PHP Code:


		
			
if ($vbulletin->userinfo['usergroupid'] == '9'  

     or $vbulletin->userinfo['usergroupid'] == '6'  

)

Another use is to display different content to users depending on if they are logged in or not. For example

PHP Code:


		
			
<?php

If ($vbulletin->userinfo['userid']!=0)

    {    

    echo "Your logged in so we can display this";

    } else {

    echo "Your not logged in so we display this";

    }

?>

Another use is to restrict advertising to people who are not logged in.
For example

PHP Code:


		
			
<?php 

if ($vbulletin->userinfo['userid'] <1) { echo"add code stuff goes here"; } 

?>

Of course you can play around with conditionals to do a whole range of things, these are just brief example snippets.

Troubleshooting

If your reading this chances are you are having problems.

Here are some common causes and fixes.

Headers already sent or cookies already sent errors. Chances are that there is something, even just a space before the 4 lines of code in part 1. Edit this and ensure that there are no spaces before it.
Path problems are the next biggest problem. Your paths must be exact else it will not work. Double check that all paths are correct.
If you are unsure what the path is place the following code in a page all by itself.

PHP Code:

<?php echo getcwd(); ?>

Name this file something like path.php then upload it to your website, browse to it and it will show you the exact path to your sites root.
Appears to login ok, but wont show you as logged in
Often caused by the vB cookie path setting.
To fix log into you vB admin area;

Code:

AdminCP -> vBulletin Options -> Cookies and HTTP Header Options -> Path to Save Cookies Change 'Suggested Settings' dropdown from '/forums/' to '/' or 'yourdomain.com'
Subdomains and cross site logins
This is a known issue with many scripts (not just this one), sometimes fixable sometimes not. Its caused by vB, PHP and your hosts security measures.

First change your "cookie domain" settings.
vB Admin > Control Panel > Cookies and HTTP Header Options > Cookie Domain
Change it from being blank to

PHP Code:

.yourdomain.com

You may need to set a post referrer in your whitelist.
vB Admin > Control Panel > General Settings > Post Referrer Whitelist
Instructions on what to enter are listed where you change this setting.

That should fix it if your forum is a subdomain.

If that fails then,
Open your /forum/login.php file and look for this code:

PHP Code:

error_reporting(E_ALL & ~E_NOTICE);

Below that add

PHP Code:

define('SKIP_REFERRER_CHECK', true);

Now save this and overwrite the file on the server with this one.

A further reported work around is to make a copy of the required Forum Forum files on your second Server. Then you must set in the config.php on the second server to use the ip of the server with which the VB-Database is running.
404 Error on expiring passwords
Cause - When redirected for expired password you are redirected to the directory that your login script is located in, not your forums root.

Fix - Edit phrase called

Code:

passwordexpired

Your current phrase should be

Code:

Your password is {1} days old, and has therefore expired. Please change your password using <a href="profile.php?{2}do=editpassword">this page</a>.

change it to

Code:

Your password is {1} days old, and has therefore expired. Please change your password using <a href="../forums/profile.php?{2}do=editpassword">this page</a>.

where ../forums/ is your forums directory.
Still got problems?
It may be a conflict with somthing already in your site.
To check this we can just make a simple page.
Call it test.php and use just this code in it.
(Make sure there is no whitespace before the 1st line)

PHP Code:

<?php $curdir = getcwd (); chdir('/path/to/your/forums'); require_once('/path/to/your/forums/global.php'); chdir ($curdir); ?> <html> <body> This is a heading This is some more stuff And another line You get the idea Just place stuff as you normally would with HTML I use CSS to style and position on my site fwiw How about we put the login box right under here? <?php require_once('/path/to/your/login_inc.php'); ?> </body> </html>

Naturally, change paths to fit your forums, then upload it.
Browse to it and run it.

Any chance of seeing a demo of some kind, I am wanting a login page for my homepage in which users can see there info on the homepage like PM's new posts, etc....

Use my 3.5 hack - (also works fine on 3.6) for that
See my sig for link to it.

But if I am using 3.6 why do I need to use 3.5 if the hack is pretty much the same, if not the same?

Also I want the hack for HTML pages, if thats possible

The 3.5 deluxe version https://vborg.vbsupport.ru/showthread.php?t=108026 has the extra stuff that you wanted like PM's
It also works fine with all versions of vB 3.6

No. It only works on PHP pages.

Awesome work!, thanks so much.

i've got it working, but only when i remove my other script that i have to call which is require_once('./vBExternal.php'); for another add-on....how do i stop the top part of the login code

Code:

<?php 

chdir('/path/to/your/forums'); 

require_once('/path/to/your/forums/global.php'); 

?>

from conflicting with the vBExternal? i found this is the only way i can do it.... otherwise the main page doesn't remember the user if i put the full url to the .php that includes the login page code with the

Code:

<?php 

chdir('/path/to/your/forums'); 

require_once('/path/to/your/forums/global.php'); 

?>

Yes there is a conflict between this and vB external.
We tried to track it down with an earlier release of this but with no luck.

A workaround others have used is use vBexternal for the front page and this hack on the rest to provide access control.

Just what the docotor ordered :) Great hack

Thanks

It works great! I have one question however, how can I display the username?

To display the username just put

PHP Code:


		
			
echo $vbulletin->userinfo['username'];

in the page where you want it.

I am trying to put $vbulletin->userinfo['username'] into a variable named $username, however it isn't working. Here is my code, is there something I am missing?

$username = $vbulletin->userinfo['username'];

I'm having an interesting problem...

If I run this hack, it deletes any variable called before it, for example, if id=6 before global.php, id = NULL afterwards?

Otherwise a great hack, but mucho help would be appreciated?

You dont have anything else that uses the variable $username do you?
What happens if you name the variable something else like $member_name ?

I have one strange issue, when someone is logged out, and they log in (or if they click the log out link) -- it opens in a new window --
is that normal behavior ?

the plan I had for this makes it a look a bit strange...
thanks for the help

I need help....

please check http://gunge.gothic-craving.com/links.php for a demo

I had to remove chdir line as it wasnt finding a file, which kept causing errors, now when I use the login box, it logs me in, but the login box stays there and at the bottom of the screen it says "done, with errors on page"

I know nothing about php so I would appreciate some help here. I have no idea what im doing or anything :(

Leigh

Hey Bill, any chance of helping me out with my id=6 problem? It's for a giant of a site, would love to get it working as I've styled it in beautifully and everything :)

Great hack! Thanks so much! I really needed this. :)

Installed!

Hey Bill:

Out of curosity, does this support multiple unique domains and subdomains,?

Ie. vBulletin is here: http://www.myvbinstall.com
But login pages are at http://beta.mydomain1.com
http://placeholder.domainworld2.com

?

Any idea what would be causing the attached error, and how to fix it? The only javascript that is included in the page is from the login_inc.php file.

hey any idea how i could make it show on whosonline page
so people who are using my page www.aur-phala.com/hotmail
will show up on whos online so i can see whos checking that page out

Some have been able to do that, but others havent.

You can try, and there is some information on that in the troubleshooting guide but dont be too disapointed if it wont work. :(

Easy way would be to just make that page in a vB forums page.
Theres a couple of hacks here that do just that.

could you link me to it
the page is a php page tho,so how wud i go abt this liek what needs to be included

is there a way i can show on my nonvb homepage who is online?

Sorry,
This mod does not support that.

I like the user authentication system that PhotoPost and ReviewPost utilize from Techimo.

I don't care about showing avatars and have no desire to do so. I just want the same functionality as PhotoPost has.

Does this hack do the same thing?

What exactly is it doing or not doing?
Any error messages?
A little more info please.

Edit:
Your path statement up the top is wrong.
I suspect that your path statement may not be correct.
Do the 2nd step of the troubleshooting guide (post 2) and see what you get.

Thanks, looking back i realized that 2AM coding is a bad idea ;) I feel ashamed now.

I've just come back to using my vb and i was wondering if this still works, if not..can someone link me? thanks
