Dynamic Announcements: Programmable Forum Home Announcement/Message with conditionals

(This hacks works with both 3.5.x and 3.6.x)

This hack allows you to post powerful dynamic announcements (changing according to different conditions) on forum home page. It differs from vbulletin's default announcements in 2 ways:

• The announcement is displayed in forum home page, not inside thread view. So visitors will read them on home page without clicking any links.
• The Hack's announcements are not static: ie. they can be powerfully programmed to display different texts according to different conditions.

For instance you can tell "why they should register" if visitor is a guest, but if he is a member with 0 posts, you can tell him why he should start posting etc.! All in one announcement! Everybody will see the relevant text according to his status. (This is the hack everybody keeps asking in the TheAdminZone.com whose using the hack for members with 0 and 1 posts.)


This version of the hack is for vbulletin 3.5.x and 3.6.x (vb 3.0.x version is here and vb 2.x version is here. 3.5 version is coded as a plugin so you can install it WITHOUT modifying vb PHP files. It is easily installed in 2 steps through your admin cp.

Basic Usage of This Hack: You can set a text in your Admin CP and it's displayed in forum home to all users. Alternatively if you want, you can set another text as a popup announcement and it is displayed to all as a pop up announcement (it can't be killed with popup killers software!)

Advanced Usage : With conditionals you can set different texts/notifications/messages/announcements and they will be displayed if your pre-configured condition applies. This allows you to create powerful announcements/private messages/texts which address their receipt only if a certain condition is met. Some examples:

You can set to show an announcement in forum home IF:

1. user is X
2. user's usergroup is Y
3. user has X posts or has more than Y posts but less than Z posts
4. his last visit time was X days ago
5. today is X, hour is between Y and Z, day is wednesday, month is Y, week is month's 2nd week, today is user's birthday
6. etc.

Some Features:

• Coded as a vbulletin pluggin. Can be installed easily without hacking PHP files.
• It's Admin CP integrated
• Smiley, BBCode, HTML, IMG tags are supported in announcements.
• You can address your users with their usernames inside announcements (Use $bbuserinfo[username] variable)
• Announcements are displayed directly in Forum Home so users are forced to read them.
• The Conditionals help you to design powerful and ever changing announcements/private messages/forum home notifications.
• Poupup announcement can not be killed by popup killer software

IMPORTANT FOR 3.x USERS:
If you were already using this hack in 3.0.x, remember to do 2 things:
BEFORE YOU INSTALL THIS HACK : Follow this instructions to remove the remnants of 3.0.x hack.
AFTER YOU INSTALL THIS HACK : Go to your admin cp / styles, find these 3 styles:
dfh_announcement
dfh_announcement_headercode
dfh_announcement_popup
and REVERT THEM so that your new templates that comes with 3.5 version will apply.

About vb4.x version:

I didn't consider porting this hack to vb4 because vbulletin has now a VERY SIMILAR feature in vb4 called "NOTICES". You can find it under your admin cp/Notices submenu/Notice Manager. It is not as powerful as this hack as this hack allows you to use any kind of conditional to produce your announcement but it is more user friendly because you don't need to deal with conditional syntax, you simply build your announcement (notice) with menus
If you install the hack, click INSTALL, thank you..

Thanks

*I'll leave it installed until tomorrow night. I'll fool around with it a little and if I figure anything out, I'll be sure to post the results. Too bad, I really liked this one!

this conflicts with photopost when the hack is configured to be used in all pages. can u fix it ?

Great mod, thanks so much for this! Installed!

For the guy wanting the img code, I believe you can use HTML.

<img src="Img URL GOES HERE" />

[[($bbuserinfo[lastvisit]<='1234704000' AND strtotime("now") < '1235258206')]]<a href='http://www.sportscardfreaks.com/forums/contests/137396-new-guess-ending-price-contest-free-cards-join.html'>New Contest For All</a> - Check it out, if you collect another sport, a replacement prize will be offered [[/($bbuserinfo[lastvisit]<='1234704000' AND strtotime("now") < '1235258206')]]

I am trying to make it so that this message shows up only to people that haven't visited the site since a certain date, and I want the messages to stop showing up at a certain date. Finally, I want the message to show up 1 time only.

No one?

Yes, it works. Version 3.8.4 - tested

[dhaimy]

thanks
an update vb4

[TexArkana]

FWIW... I'm using this in vB 3.8.5, along with the hack to make the announcement appear on every forum page, not just FORUMHOME. Works fine. (Nice mod BTW. Thanks!)

    $logician_dfa_incoming1 = ereg_replace("\]\][\r\n\f \t]*\[\[", "]][[", $logician_dfa_incoming1);
    // Recursively process nested conditionals
    $logician_dfa_incoming1 = trim(dynamic_b($logician_dfa_incoming1));
    // Finish up by running result through BbCode parser
    if (trim($logician_dfa_incoming1)) 
    {
        $parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list()); 
        $logician_dfa_incoming1 = $parser->do_parse($logician_dfa_incoming1, 1, 1, 1, 1, 1, 1); 
    }
    return $logician_dfa_incoming1;
}

function dynamic_b($dc3dreamer_dfa_incoming1)
{
    extract ($GLOBALS);

    while (preg_match("/\[\[(.*)\]\](.*)\[\[(\/\\1)\]\]/siU", $dc3dreamer_dfa_incoming1, $matches14))
    {
        @eval ('if ('.stripslashes($matches14[1]).') { $eval_deger= "1"; } else { $eval_deger= "0"; }'); 
        if ($eval_deger == 1)           //if conditional applied, replace with inner text
        {
            $dc3dreamer_dfa_incoming1 = dynamic_b(str_replace($matches14[0], $matches14[2], $dc3dreamer_dfa_incoming1));
        }
        else                            // Conditional not applied, delete the whole chunk
        {
            $dc3dreamer_dfa_incoming1 = dynamic_b(str_replace($matches14[0], '', $dc3dreamer_dfa_incoming1));
        }
    }
    return $dc3dreamer_dfa_incoming1;
}

The recursion continues until there are no conditionals found, at which point the final result is passed through the BbCodeParser at the end of the first method. The trick was to remove line endings from conditionals that follow one another with just newlines between. They generated extra breaks and line spacing after going through the BbCode parser. You might want to remove the * in the regexp for the call to ereg_replace(). Er, do I really have to name my parameter variable like it might exist in the host page? I hope not, but I copied Logician's style. I would have used sumpin' like $src for the parameter var :nervous:

I'm slowly coming up to speed on PHP :nervous: I was killed by the $bbuserinfo[membergroupids] variable testing against values, till my ancient Perl tablets fell out on the ground. Yumba! It can be an array and it may not even exist! Well, rookie me! I got it now.

This is so nice! Nested conditionals open up a whole new world of possibilities, but ... Thank you Logician Thank you Logician Thank you Logician ...

I have read almost all of this thread but can't figure out where to put this code ....
Does it goes in the window where you put the announcements, or you need to do some file editing?
A short how to use description would be v appreciated.

Very good mode, mostly for the pop up. The conditional announcement can be done easyer with other mods however this one gives maximum flexibility.
For example I need to make an anouncement show if you have not selected aditional usergroup and probably this one can help.
Thanks for the mod. Will install soon.
