[h2]validate_channelname[/h2] Called when creating a new channel or changing the channel name in mod/settings.php Hook data consists of an array array( 'name' => supplied name ); If the hook handler determines the name is valid, do nothing. If there is an issue with the name, set $hook_data['message'] to the message text which should be displayed to the member - and the name will not be accepted. Example: [code] if(mb_strlen($hook_data['name']) < 3) $hook_data['message'] = t('Name too short.'); [/code]
