I couldn't get it working either. After looking at the code, I made a fix. In functions.inc.php, replace the entire function bb_decode($text) with:
function bb_decode($text)
{
$text = " " . $text;
static $bbcode_tpl = array();
static $patterns = array();
static $replacements = array();
// First: If there isn't a "[" and a "]" in the message, don't bother.
if (! (strpos($text, "[") && strpos($text, "]")) )
{
return $text;
}
// [b] and [/b] for bolding text.
$text = str_replace("[b]", '<b>', $text);
$text = str_replace("[/b]", '</b>', $text);
// [u] and [/u] for underlining text.
$text = str_replace("[u]", '<u>', $text);
$text = str_replace("[/u]", '</u>', $text);
// [i] and [/i] for italicizing text.
$text = str_replace("[i]", '<i>', $text);
$text = str_replace("[/i]", '</i>', $text);
//if (!count($bbcode_tpl)) {
// We do URLs in several different ways..
$bbcode_tpl['url'] = '<span class="bblink"><a href="{URL}" target="_blank">{DESCRIPTION}</a></span>';
$bbcode_tpl['email']= '<span class="bblink"><a href="mailto:{EMAIL}">{EMAIL}</a></span>';
$bbcode_tpl['url1'] = str_replace('{URL}', '\\1\\2', $bbcode_tpl['url']);
$bbcode_tpl['url1'] = str_replace('{DESCRIPTION}', '\\1\\2', $bbcode_tpl['url1']);
$bbcode_tpl['url2'] = str_replace('{URL}', 'http://\\1', $bbcode_tpl['url']);
$bbcode_tpl['url2'] = str_replace('{DESCRIPTION}', '\\1', $bbcode_tpl['url2']);
$bbcode_tpl['url3'] = str_replace('{URL}', '\\1\\2', $bbcode_tpl['url']);
$bbcode_tpl['url3'] = str_replace('{DESCRIPTION}', '\\3', $bbcode_tpl['url3']);
$bbcode_tpl['url4'] = str_replace('{URL}', 'http://\\1', $bbcode_tpl['url']);
$bbcode_tpl['url4'] = str_replace('{DESCRIPTION}', '\\2', $bbcode_tpl['url4']);
$bbcode_tpl['email'] = str_replace('{EMAIL}', '\\1', $bbcode_tpl['email']);
// [url]xxxx://www.phpbb.com[/url] code..
$patterns[] = "#\[url\]([a-z]+?://){1}([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+\(\)]+)\[/url\]#si";
$replacements[] = $bbcode_tpl['url1'];
// [url]www.phpbb.com[/url] code.. (no xxxx:// prefix).
$patterns[] = "#\[url\]([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+\(\)]+)\[/url\]#si";
$replacements[] = $bbcode_tpl['url2'];
// [url=xxxx://www.phpbb.com]phpBB[/url] code..
$patterns[] = "#\[url=([a-z]+?://){1}([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+\(\)]+)\](.*?)\[/url\]#si";
$replacements[] = $bbcode_tpl['url3'];
// [url=www.phpbb.com]phpBB[/url] code.. (no xxxx:// prefix).
$patterns[] = "#\[url=([a-z0-9\-\.,\?!%\*_\#:;~\\&$@\/=\+\(\)]+)\](.*?)\[/url\]#si";
$replacements[] = $bbcode_tpl['url4'];
// [email]user@domain.tld[/email] code..
$patterns[] = "#\[email\]([a-z0-9\-_.]+?@[\w\-]+\.([\w\-\.]+\.)?[\w]+)\[/email\]#si";
$replacements[] = $bbcode_tpl['email'];
//}
$text = preg_replace($patterns, $replacements, $text);
return $text;
}
Should do the trick.
