bbcodeparse.php

[TosaInu]

Hello,

We have two hacks/tweaks in that file, one is a table hack (using custom BB code in ACP results in dangerous code) and a line that strips html (imported code left from ancient boards like UBB).

This was the code that stripped HTML

inlucudes/functions_bbcodeparse.php

1. find
// ###################### Start bbcodeparse2 #######################
function parse_bbcode2($bbcode, $dohtml, $dobbimagecode, $dosmilies, $dobbcode, $iswysiwyg = 0, $donl2br = 1)
{
// parses text for vB code, smilies and censoring

	global $DB_site, $vboptions, $bbuserinfo, $templatecache, $smiliecache;
	global $html_allowed;

add

//strip html M:\vbul-hacks\striphtml\vBulletin_org Forum - Removing HTML Code From Posts.htm
$bbcode = strip_tags(unhtmlspecialchars($bbcode)); 
//End Hack

The author who made the table hack isn't going to port it (afaik), it's a code that can have some options and is frequently used. It adds new code only and I wonder whether it would just work in some new file?

BB code tables by JohnWoo :)
It still needs optimization, but should work fine already :)

How it works :
1) starting code is [table] or [table 1 2 3] where
1 2 3 any numbers separated by space
first - border
second - cellpadding
third - cellspacing

- ending tag is always [/table]
- table lines separated by line break
- each line can have 7 styles. To specify a style add in the beginning number and ^ symbol without spaces
example:
2^
you may skip 7^ - it is default (alt1) style
- ceils in line separated by | 
- there is no need to add | before first and after last ceil
- each ceil can have each own align. Use align mark as a first symbol of ceil without spaces
blank (default) - left
= - center
~ - right

- you can use any other BB code inside ceils :) 
- if number of ceils different in lines, last ceil of shorter lines will get colspan= with needed number

so table in post may look like


[table 1 3 0]
1|2|test 16798789789797979799879797979|4|5|6|7
1^~right with colspan
2^333|=center with colspan 
3^1|2|left with colspan 
4^1|~center without colspan|3|4|5|6|7
5^1|blablabla|3|4|5
6^1|2|3|4|5|6|7
[/table]


code changes
includes/functions_bbcodeparse.php
1. find 
	// do new lines
	$wysiwygtype = null;

before it add

$bbcode = preg_replace("~(\[table.+\[/table\])~iUse", "fetch_html_table('\\1')", $bbcode);	

2. in the end of file add 2 functions.

function get_table_class($id) {
		$id = intval($id);

			return " class=\"alt2\"";
		} elseif ($id == 2) {

		} elseif ($id == 4) {
			return " class=\"highlight\"";
		} elseif ($id == 5) {
			return " class=\"alt3\"";
		} elseif ($id == 6) {
			return " class=\"smallfont\"";
		} else {
			return " class =\"alt1\"";
		}
}

	if (preg_match("~\[table( (\d)+ (\d)+ (\d)+|)\](.+)\[/table\]~isU", $tblcode, $rows)) {

		$bb_table = array();
		$tbl_k=0;
		$tbl_max = 0;
		$tbl_all = split("\n",trim($rows[5]));
		if (is_array($tbl_all)) {
			foreach ($tbl_all as $tbl_i => $tbl_string) {

			}
		}
