[How To] Add BBCODES into pun_bbcode OFFICIAL Extension

Youtube BBCode example: [youtube]http://youtube.com/watch?v=uDybmxbKf4Y[/youtube]

1. Modify $tags_without_attr = array('b', 'i', 'u', 'url', 'email', 'img', 'list', 'li' => '*', 'quote', 'code', 'youtube'); #add youtube in /extensions/pun_bbcode/bar.php

2. add youtube image button to /extensions/pun_bbcode/buttons/[your_style]/

3. In includes/parser.php modify function handle_url_tag replace:

if ($full_url == $link)
    return '[url]'.$link.'[/url]';
else
    return '[url='.$full_url.']'.$link.'[/url]';
---------------------------------------------------------
with:
if ($full_url == $link)
    if(strpos($link, 'youtube.com/watch') === 0)
        return '[url]'.$link.'[/url]';
    else
        return $link;
else
    return '[url='.$full_url.']'.$link.'[/url]';
-----------------------------------------------------
this will not transform your youtube url into a href link before inserting message into db.


4. In includes/parser.php modify function do_bbcode  add (at the end of $pattern and $replace array):
$pattern[] = '#\[youtube\]http://(?:www\.)?youtube.com/watch\?v=([0-9A-Za-z-_]{11})[^[]*\[/youtube\]#is';
and
$replace[] = '<object width="425" height="350"><param name="movie" value="$1"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/$1" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"></embed></object>';

5. If you have upgraded from 1.2 and used [youtube][/youtube] BBCode run this queries on the posts table:
- update `forum_posts` set `message` = replace(`message`, '[youtube][url]','[youtube]') WHERE message LIKE '%[youtube][url]%
- update `forum_posts` set `message` = replace(`message`, '[/url][/youtube]','[/youtube]') WHERE message LIKE '%[/url][/youtube]%''

        // Remove empty tags
        while ($new_text = preg_replace('/\[(b|u|i|h|colou?r|quote|code|youtube|img|url|email|list)(?:\=[^\]]*)?\]\[\/\1\]/', '', $text))

    $tags = array('quote', 'code', 'youtube', 'b', 'i', 'u', 'color', 'colour', 'url', 'email', 'img', 'list', '*', 'h');

    $tags_inline = array('b', 'i', 'u', 'color', 'colour', 'h', 'youtube');

    // Tags we can automatically fix bad nesting
    $tags_fix = array('quote', 'youtube', 'b', 'i', 'u', 'color', 'colour', 'url', 'email', 'h');

    $pattern[] = '#\[youtube\](.*?)\[/youtube\]#s';
    $replace[] = '<object width="425" height="350"><param name="movie" value="http://www.youtube.com/v/$1"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/$1" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"></embed></object>';
