MyBB Community Forums

I'm trying to catch hashtags in posts.  The problem is when I use parse_message_end, it doesn't actually override them.

But when I use parse_message it does, but it also messes up special characters because at that point they are escaped and have their #blah id in place.  

Paul H. had used parse_message_end in his plugin a while back for MyBB 1.6, but that method doesn't seem to work in 1.8.

What would be the correct place to hook in?

I just tried and it seems to work fine for me. Can't say more without seeing your code..

The code is Paul H's old MyTags plugin with some modifications I made to try and make it work with MyBB 1.8 as well as support foreign characters and not just English ones (since I saw someone complaining about that).

Well, found 3 mistakes so far:

1. The regex didn't really look correct for me and I was too lazy to write another one myself, so I replaced it with a random find from stackoverflow: http://stackoverflow.com/a/16942496 Now it's parsed.
2. Umm..

style="display:inline;

Incorrect HTML syntax.
3. What's this?

document.forms[0].submit()

It would submit the 1st form on the page afaik. Replaced it with other JS code.

So here's my function:

$plugins->add_hook("parse_message_end", "tag_parse");
function tag_parse($message)
{
	global $mybb;
	
	$repl = <<<EOF
<form method="post" action="{$mybb->settings['bburl']}/search.php" style="display: inline;">
<input type="hidden" name="action" value="do_search" />
<input type="hidden" name="postthread" value="1" />
<input type="hidden" name="forums" value="all" />
<input type="hidden" name="showresults" value="posts" />
<input type="hidden" name="keywords" value="$1" />
<a href="javascript:void(0)" onclick="$(this).closest('form').submit()" style="display: inline;">$1</a>
</form>
EOF;
	
	$tweet = $message;
	$message = preg_replace("/#([^#]+)[\s,;]*/i", $repl, $tweet);
	
	return $message; 
}

$message should be passed by reference instead though, just FYI.

Thanks guys, that helps a lot!
