Clarification of some code..

Ok.. well i’ve temporally moved off the releases engine to focus on MTF’s base. So right now I am going through the code and « trimming » the um-needed code. While going through some of your original code was there and i am trying to figure out what it is there for and if i should keep it or not. Here are the code samples:
From plugin ‘Add default details on Add Forum’:

$forum[‘mtf_inpost’] = $vbulletin->options[‘mtf_inpost’];
$forum[‘mtf_highlight’] = $vbulletin->options[‘mtf_highlight’];
$forum[‘mtf_attachlimit’] = $vbulletin->options[‘mtf_attachlimit’];
$forum[‘mtf_feature’] = $vbulletin->options[‘mtf_feature’];
[/CODE]

From plugin ‘Add Highlight Effect on Showthread’:

if($foruminfo[‘mtf_type’] != ‘default’ AND $foruminfo[‘mtf_highlight’] == ‘lightbox’)
{
global $header, $headinclude;
$headinclude .= ‘






‘;
}

From plugin ‘deactivate the Attachment Manager if member have no permission in editpost’:

if($foruminfo[‘mtf_type’] AND $foruminfo[‘mtf_type’] != ‘default’ AND !can_moderate() AND $foruminfo[‘mtf_inpost’])
{
switch($foruminfo[‘mtf_inpost’])
{
case ‘1’: # if the thread author only can post AND only in firstpost
if($postinfo[‘postid’] != $threadinfo[‘firstpostid’]) unset($vbulletin->userinfo[‘attachmentextensions’]);
break;
case ‘2’: # if the thread author only can post
if($vbulletin->userinfo[‘userid’] != $threadinfo[‘postuserid’]) unset($vbulletin->userinfo[‘attachmentextensions’]);
break;
default: # choice #3, anybody can post!
break;
}
}

From plugin in location forumdata_start (partial code):

$this->validfields[‘mtf_postbit’] = array(TYPE_BOOL, REQ_NO);
$this->validfields[‘mtf_authorbio’] = array(TYPE_BOOL, REQ_NO);
$this->validfields[‘mtf_reflink’] = array(TYPE_BOOL, REQ_NO);
$this->validfields[‘mtf_firstpost’] = array(TYPE_BOOL, REQ_NO);
$this->validfields[‘mtf_highlight’] = array(TYPE_STR, REQ_NO);
$this->validfields[‘mtf_attachlimit’] = array(TYPE_UINT, REQ_NO);
$this->validfields[‘mtf_feature’] = array(TYPE_UINT, REQ_NO);
$this->validfields[‘mtf_inpost’] = array(TYPE_UINT, REQ_NO);
$this->validfields[‘mtf_threadpreview’] = array(TYPE_UINT, REQ_NO);

$forum = $vbulletin->options;
$forum = $vbulletin->options;
