I'm working off the plugin by Andreas too, but trying to modify it some to force a page refresh if its a double post (if its from the quick reply box).
I'm having one issue if I do a double post via the advanced reply box, it refreshs then says "this forum is no longer accepting new posts" or something like that???
This would be great if it was a standard vB option, I think everyone gets annoyed by double-posters...
Update -
If I set the following in either of the postdata_xxx hooks, I can get the page to refresh after posting a quickreply (since ajax is enabled). However, the reply text shows up twice, and I have no idea why. I've peeled through the newreply.php, class_dm_threadpost.php, and functions_newpost.php files with no luck.
Code:
$this->registry->GPC['ajax'] = false;
Anyone have some help they want to give?
