Allow Group to Read Titles / Not Content

Tested and working in 3.0.3 - 3.0.7

This hack will enable you to DISABLE SHOWTHREAD according to USERGROUP.This will allow all your members to view titles and topic counts found within a section. Think of it as "window shopping". Your members will be able to read all topics from the forumdisplay.php page but, will not be allowed to read it's content unless they have permission

The edits below will prevent anyone from viewing the contents of a post from within showthread, printthread, showpost, and archives.

This feature can be used on a per USERGROUP and /or per FORUM basis. You, as the admin, will have complete control.

You will need to modify:

• includes/init.php
• includes/adminfunctions_forums.php
• admincp/resources.php
• admincp/usergroup.php
• showthread.php
• archive/index.php
• printthread.php
• showpost.php
• archive.css

Add 3 new phrases.
MOD VERSION 1.05

• Fixed issues concerning the archives - eg. blank page was displayed ... now, thread links are viewable but not active (if not allowed).

MOD VERSION 1.01

• now with personal NOT ALLOWED message
• Easier to install
• now add the ability to allow users to view their own posts/threads (view below code)
• archive section changed to NOT display links to content that is not READABLE
• added a message to archive section if user cannot read content

Allow User To View And Post Into Their Own Threads:
If you want to allow users to view and post their own threads and have access to them ... use this code in showthread, printhread, and showpost.php:

// ================================================= \\
// == [ ALLOW GROUP TO READ TITLE / NOT CONTENT - GTP BEGIN ]
                 if (!($forumperms & GTPCANREADCONTENT)AND ($thread['postuserid'] != $bbuserinfo['userid']))
                 {
                     eval(print_standard_error('gtp_cannot_read'));
                 }
// == [ 00-00-2004 - GTP END ]
// ================================================= \\

NOTE: You may have to use "$threadinfo['postuserid]" on some of the pages.

Disable Thread Preview
To disable thread previews on forums that user cannot read content do the following edits:
FIND in functions/forumdisplay.php:

    // format thread preview if there is one
    if ($ignore["$thread[postuserid]"])
    {
        $thread['preview'] = '';
    }
    else if (isset($thread['preview']) AND $vboptions['threadpreview'] > 0)
    {
        $thread['preview'] = strip_quotes($thread['preview']);
        $thread['preview'] = htmlspecialchars_uni(fetch_trimmed_title(strip_bbcode($thread['preview'], false, true), $vboptions['threadpreview']));
    }

REPLACE IT WITH:

// ================================================= \\
// == [ ALLOW GROUP TO READ TITLE / NOT CONTENT - GTP BEGIN ]
    $forumperms = fetch_permissions($foruminfo['forumid']);
    // format thread preview if there is one
    if ($ignore["$thread[postuserid]"] OR !($forumperms & GTPCANREADCONTENT))
    {
        $thread['preview'] = '';
    }
    else if (isset($thread['preview']) AND $vboptions['threadpreview'] > 0)
    {
        $thread['preview'] = strip_quotes($thread['preview']);
        $thread['preview'] = htmlspecialchars_uni(fetch_trimmed_title(strip_bbcode($thread['preview'], false, true), $vboptions['threadpreview']));
    }
// == [ 00-00-2004 - GTP END ]
// ================================================= \\

Example Of How Hack Works:
I have a forum with (sub-forums) ... however, one of the sub-forums is private (for PREMIUM members only). Here's how the settings would look like.

In USERGROUP MANAGER (this is a global setting) set "Group can read content?:
UNREGISTERED - YES
REGISTERED - YES
PREMIUM - YES

The global setting will be transferred to all forums; but, we have a sub-forum that is only for PREMIUM MEMBERS so...

In FORUM PERMISSIONS MANAGER set private forum to:
UNREGISTERED - NO
REGISTERED - NO
PREMIUM - YES

thanks for the feedback Watson

When logged in as a non administrator, I can access about 3 threads, then I get access denied with a user account. I also noticed that when this is happening, the user's ip adress is listed twice, once as the username and the other as guest.

I can't help without a url.

Recheck your permissions and make sure it's set right.

    if (!($forumperms & GTPCANREADCONTENT) OR !preg_match("#(google|slurp@inktomi|yahoo! slurp)#si", $_SERVER['HTTP_USER_AGENT']))
    {

    }
// == [ 00-00-2004 - GTP END ]
// ================================================= \\ 


after seeing the useragent details in [this thread] but I noticed that the inktomi spider was still being denied access when it hit showthread.php, any ideas?


Cheers,
Robert

it should be "AND" instead of "OR" in the follwing line:

if (!($forumperms & GTPCANREADCONTENT) OR !preg_match("#(google|slurp@inktomi|yahoo! slurp)#si", $_SERVER['HTTP_USER_AGENT']))

am i right?

i changed the line w/o thinking, and promptly shut off access to everybody.

but, how can i select a seperately error messages, if a "non read user" want to read topics from a closed forum? i want to put some urgent information on this site, how a user can get access to the closed forum. so i dont want to take the standard error page.

is there any way ?


have thanks !

tom :banana:

hallo again,

is there no way for a seperate error site ?

thanks

i havent tried this, so dont take this at face value, but i think this should work

in showthread.php, change

    if (!($forumperms & GTPCANREADCONTENT))
    {
        print_no_permission();
    }

to

    if (!$forumperms)
    {
        print_no_permission();
    }
    elseif (!GTPCANREADCONTENT)
    {
        print_my_no_permission();
    }

You will have to write this new function, "print_my_no_permission" by yourself. You can take inspiration from the default vBulletin function.

Similar changes will have to be made to showpost, archive and printthread.


Hope this helps.
