FAQ
Q: what exactly is Template_Option.txt?
A: Basically that exention was provided as a request to cover sites with the template modification that adds a "header" to each grouping.

Q: How do I show a forum depth greater than 2?
A: Open vB Admin cp set forum depth to your required level. Then create the additional templates. For template examples see https://vborg.vbsupport.ru/showthrea...465#post250465

Q: Can sub-forums be collapsed?
A: Yes. See the above answer for example templates.

Q: XYZ doesn't work help.
A: Check that all the template changes required have been made, 99% of problems are due to incorrect template alteration. Also use the cx_test.php to automatically check your installation!

Yes, that's what i did...it still doesn't work....

When i put the code in the level2_nopost, it works like a charm.

when i put the code in the new level3_nopost i created, it doesn't work.

Define doesn't work.

The level3 template doesn't appear?
The plus minus symbols don't appear but the level3 template does?
The level4 template doesn't appear?

[jackomo]

i created both level3_no post and level4_post templates and they appear under the custom templates.

These 2 templates were not there before, i only had level 1 and level 2, so i added them.

When i go back into the forums and click through each category, i see the templates, but no (+/-) symbols at the third level.

Example...

Canada (Category 1) - level 1 no post - i can see this page.
|
Computers (Category 2) - level 2 no post - i can see this page.
|
Hardware (Category 3) - level 3 no post - i can see this page but no (+/-) next to it.
|
Part 1, Part2,...(Postable forums) - level 4 post - i can see this page but it does not collapse

[dabean]

Define "click through each category", as this hack only applies to the main index page. It does not apply to any of the sub views inside forumdisplay.

[jackomo]

Well, when the main page comes up you will see Canada as a main category then Computers as a sub-category under it.

When i click on Computers, there is another sub-category called Hardware under that.

Hardware contains a bunch of parts that i would like to collapse.

Is this possible with your hack?

If when you click on the category the url changes from index.php to forumdisplay.php then no.

This hack was designed for cases where lots of forums are required to be display on the home page.

Most of the installations using forums 3 or more levels deep with this hack alter the "depth of forums" setting to show all the required forums on the index page.

vBulletin Options > Forums Home Page Options > Depth of Forums

[jackomo]

aahh...ok...the URL does change to forumdisplay.php

I changed the forum depth to 3 as you suggested.

Now the (+/-) appears...

Ok....well, thanks for all your help i really appreciate it.

Sorry to have wasted your time.

Hey Dabean,

How hard would it be to change this chack to work with Forum Display?

[dabean]

Just copy paste the existing code into the correct places inside forumdisplay.php. No further template modifications are required.

Find

PHP Code:

function makeforumbit($forumid,$depth=1,$permissions='') {
  global $DB_site,$bbuserinfo,$iforumcache,$ipermcache,$imodcache,$session,$accesscache,$usergroupdef,$noperms;
  global $showlocks,$hideprivateforums,$showforumdescription,$forumdisplaydepth,$dateformat,$timeformat,$forumshown,$enableaccess;
  global $bbforumview; 


Below add

PHP Code:

// expand collapse hack
global $BrowserDOM, $collapsedstate;
// end expand collapse hack 


Find

PHP Code:

if ($forum['cancontainthreads']==1) {
  $tempext = '_post';
} else {
  $tempext = '_nopost';
} 


Below add

PHP Code:

// expand collapse hack
if ($BrowserDOM==True) {
  if ((!isset($z)) or ($depth==1)) {
    $z=0;
  } else {
    $z++;
  }
  // get state of collapse
  if ($forum[parentid]==-1) {
   $collapsedstate=$forum['collapsed'];
  }
  // auto collapse forums based on forum setting
  if ($collapsedstate==1) {
   $fhomeexpandstyle="style=\"visibility:hidden; display:none;\"";
  } else {
   $fhomeexpandstyle="";
  }

  // auto collapse forums for user
  if (getViewSetting($forum['parentid'])==1) {
   $fhomeexpandstyle="style=\"visibility:hidden; display:none;\"";
  } elseif (getViewSetting($forum['parentid'])==2) {
   $fhomeexpandstyle="";
  }

  // display correct item (this can not be simplified into the block above
  // due to CSS2 defining special display values for tables, eg display:table-row;)
if ($collapsedstate==1) {
   $divexpand = "display: inline;visibility: visible;";
   $divcollapse = "display: none;visibility: hidden;";
} else {
   $divexpand = "display: none;visibility: hidden;";
   $divcollapse = "display: inline;visibility: visible;";
}

if (getViewSetting($forum['forumid'])==1) {
   $divexpand = "display: inline;visibility: visible;";
   $divcollapse = "display: none;visibility: hidden;";
  } elseif (getViewSetting($forum['forumid'])==2) {
   $divexpand = "display: none;visibility: hidden;";
   $divcollapse = "display: inline;visibility: visible;";
  }
  eval("\$expandcontract = \"".gettemplate("forumhome_expandcontract")."\";");
}
// end expand collapse hack 


Find:

PHP Code:

$forumbits=makeforumbit($forumid, 1, $permissions); 


Above add:

PHP Code:

// expand collapse hack
$fviewcache=BuildViewSettingCache(); // create cache
// end expand collapse hack 


Find

PHP Code:

if ($forumshown==1) {
  eval("\$forumdisplay[forumslist] = \"".gettemplate('forumdisplay_forumslist')."\";");
} else {
  $forumdisplay['forumslist']='';
} 


Change it to:

PHP Code:

if ($forumshown==1) {
  // expand collapse hack
  if ($BrowserDOM==True) {
    eval("\$expandcontractscript = \"".gettemplate('forumhome_expandjscript')."\";");
  }
  // end expand collapse hack
  eval("\$forumdisplay[forumslist] = \"".gettemplate('forumdisplay_forumslist')."\";");
} else {
  $forumdisplay['forumslist']='';
} 


Alter:

PHP Code:

require('./global.php'); 


into:

PHP Code:

// expand collapse hack
require('./admin/getbrowser.php');
require('./admin/getforumview.php');
$BrowserDOM=GetBrowserDOM2();
$templatesused.=',forumhome_expandcontract,forumhome_expandjscript';
// end expand collapse hack

require('./global.php'); 


[jackomo]

ok...made the changes to forumdisplay.php as you said and the (+/-) didn't show up.

so, i edited the forumdisplay_forumbit_level1_nopost, by adding the "$expandcontract" and the (+/-) shows up but it doesn't work.

so, i edited the forumdisplay_forumbit_level2_post, by changing to "<tr id="f$forum[parentid]z$z" $fhomeexpandstyle align="center">"

When i put my mouse over the (+/-), it says there is an error on the page.

[jackomo]

We have a winner!

I got it working...

i forgot to edit the forumdisplay template

I added the "$expandcontractscript" to the forumdisplay template and it is working perfect now.

Thanks for all your help....
