unexpected filter behaviour?

[Patrick_]

You're.

I've created a plugin to solve this issue:

PHP Code:

1 2 3 4 5 6 7 8

$plugins->add_hook('forumdisplay_start', 'plugin_forumdisplay_start', 1); function plugin_forumdisplay_start() { global $mybb; if ($mybb->input['filtertf_field'] == '') unset($mybb->input['filtertf_field']); }
