Usage

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

You can resize avatars, keeping them to their origional proportions to make them fit your prefered layout.
For instance, if you are using a fixed width column layout.
Do this by editing lines 5 and 6 in login_inc.php
These values are in pixels.

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.

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

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

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

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

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

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

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

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.

1. 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.
   
   
   
2. 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.
   
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

   
   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.
   
   
   
3. 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;
   
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

   
   
   
4. 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
   
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

   
   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:
   
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

   
   Below that add
   
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

   
   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.
   
   
   
5. 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
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

   
   Your current phrase should be
   
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

   
   change it to
   
   
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

   
   where ../forums/ is your forums directory.
   
   
   
6. 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)
   
   

   Block Disabled:      (Update License Status)
   Suspended or Unlicensed Members Cannot View Code.

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

[Hornstar]

does it have to be on the same server or can you make it read off the database from another site?

Just realised I based part of this on a modified table structure.
Will fix in the next day or two.

[Billspaintball]

Ok, I think I have a fix for the problem.
Unfortunantly, I dont have access to an unmodified vB database to test it on.

If anyone who has had the problem wants to try the fix, its available here.
http://www.cwp.id.au/login_inc.zip
Please let me know if it fixes the problem, so I can modify the file here appropriatly.

I'm getting this error wether I'm logged into the forums already or not:
Fatal error: Call to a member function query_read() on a non-object in /var/www/html/forums/includes/login_inc.php on line 139

This is all running on localhost. Am I missing something?

[Billspaintball]

did you use the revised test one in this post
http://www.vbulletin.org/forum/showp...6&postcount=12
or the one on the 1st post?

[dkleehammer]

I used the revised version. For some reason the db is not being set as an object. Is there something that I need to do besides editing one line and including this file in the main page?
