if() vBCode - Private Post Text Hack

Important News: This hack is now out of beta testing and is now in alpha.

What this hack does, is add a if() vB Code where you can enter formulas that if true, the user will be able to see the private text in the post, if it shows up false, its hidden from the users sight. This hack doesnt use any queries at all. Also the if() vB Code also supports other vB Codes inside of it.

The formulas can contain both functions and varibles such as $bbuerinfo[userid] or strtolower(), you can add a list of allowed functions to it and all others functions that arent allowed are removed from the code to prevent security issues.

All security issues and exploits have now been fixed. This hack has settings where you can allow all users to use it or just allow admins to use it. Theres also a setting that you can change to allow admins to see all the private text in posts even if they normaly cant see it.

The code part of the vB Code ( if(code) ) uses the same syntax as php script, so if you wanna check if a varible equals something, you must use == instead of =, also all varibles from $bbuserinfo also have there own varible, what i mean by this is that $bbuserinfo[username] is also $bbusername and $bbuserinfo[posts] is also $bbposts, with these specail varibles, it is optional to add a $ in front of it, so $bbusername and bbusername will both work.

Also theres a feature where admins can see the forumula that was used next to the text "Private Text:", it is shown is (code used here), other members will just see "Private Text:".

Examples of the If() vB Code:
[if($bbuserid>0)]Thank you for joining![/if]
[if(bbuserid>0)]Thank you for joining![/if]

[if($bbusername=="Admin")]Whats up?[/if]
[if(bbusername=="Admin")]Whats up?[/if]

[if($ourtimenow>=$post[dateline]+((7*24)*60*60))]Text To Display 1 week from this post[/if]

[if(bbuserid>0 and bbposts>100)]Keep up the posting [/if]

[if(bbusergroupid==6 or bbusergroupid==7)]Important Text[/if]

The text below already contains the fix.

Also I hope you enjoy the hack, If you have any problems, ideas, or just feedback, feel free to post.

Screenshots:
Heres a screenshot of a test post I did with the if() vB Code, the user who made the post can see all the private text in the post by default.

(Note: The private text table can esily be edited in the "privatetext_style" style in headinclude after the hack is installed:

Heres a screen shot of the same post but after I logged out, so this is what the guest would see.

You can add a bg image in the style with:

BACKGROUND-IMAGE: url("http://www.yoursite.com/images/some-image.gif");

Heres a neat little piece of code:

[if($ourtimenow>=$post[dateline]+((7*24)*60*60))]Text To Display 1 week from this post[/if]

Hmm you must have an older version of php, you can comment that section out for now and only allow admins to use it and ill see f i can make a fix for it when i get back from classes.

ok, try changing your doif function to this, it wont remove the functions but it will remove the ( ) from the code instead and that should disable any functions in the code.

PHP Code:

// ###################### Do IF #######################
function doif($code,$text,$output=0) {
  extract ($GLOBALS);
  
  //Editable Options Below
  $admin_only = false; //Set to true if you want only admins to use this.
  $admin_view_all = false; //Set to true if you want to allow admins to view all text.
  //Editable Options Above
  
  $postadmin = false;
  if ($post['usergroupid']==6 or $postinfo['usergroupid']==6)  $postadmin = true;
  $isadmin = false;
  if ($bbuserinfo['usergroupid']==6)  $isadmin = true;
  if ($code and (!$admin_only or $admin_only and $postadmin)) { 
      unset($codestuff);
    while (list($key,$val)=each($bbuserinfo)) {
      $codestuff .= '$bb'.strtolower($key).' = "'.$val.'";';
      @define("bb".strtolower($key),$val,true);
    }
    @eval($codestuff);
    $code = str_replace("(","",$code);
    $code = str_replace(")","",$code);
    @eval ('if ('.stripslashes($code).') { $eval_code= "1"; } else { $eval_code= "0"; }');
     if ($eval_code or $bbuserinfo['userid'] == ($post['userid'] or $postinfo['userid']) or ($isadmin and $admin_view_all)) {
         if (!$output) {
           return "<table border=\"0\" align=\"center\" width=\"90%\" cellpadding=\"3\" cellspacing=\"1\"><tr><td><smallfont><b>Private Text: ".iif($isadmin,"(".stripslashes($code).")","")."</b></smallfont></td></tr><tr><td class=\"privatetext_style\">".bbcodeparse($text)."</td></tr></table>";
        } else return "[if(".stripslashes($code).")]".$text."[/if]";
     } else {
       return "";
     }
  }
  if ($admin_only and !$postadmin) return "[if(".stripslashes($code).")]".$text."[/if]";
  else return bbcodeparse($text);
}

Meh, I'll just use the old version set to admins only. That is, until my PHP version is FINALLY upgraded.

I sent you a PM about it.

This is great work. Well done! Obviously, use it with care - I would restrict this only for yourself - too easy to be abused or cause db errors by accident.
