You could need to show up a terms and conditiona page for a regidtration tracker.
There is 2 ways to display the terms and conditions by using a static text field with a wiki parse description
You can add in the description

[http://mysite.com/tiki-print.php?page=Terms+and+Conditions|See our terms and conditions|shadowbox;title=Terms and Conditions;]

{IFRAME(src="tiki-print.php?page=Terms+and+Conditions" width="600px" height="300px") /}

If you want to know on which wiki page or which file gallery an Anonymous has special perm

SELECT pageName FROM tiki_pages
WHERE md5( concat( 'wiki page', pageName ) ) in (select objectid from users_objectpermissions where groupName='Anonymous' and objectType='wiki page');
SELECT name, galleryId FROM tiki_file_galleries
WHERE md5( concat( 'file gallery', galleryId ) ) in (select objectid from users_objectpermissions where groupName='Anonymous' and objectType='file gallery');

Just put a margin-left and margin-right top auto and a width ok x px on the #main or #main-shadow description

The new module CALENDAR_NEW can be used like this

{wiki}{literal}
   {MODULE(module=calendar_new, viewmode=month, notitle=y) /}
   {MODULE(module=calendar_new, viewmode=month, month_delta=+1, notitle=y) /}
   {MODULE(module=calendar_new, viewmode=month, month_delta=+2, notitle=y) /}
{/literal}{/wiki}

Be carefull to put this at the end of tiki-calendar.tpl and to move this div up with absolute positionning (because otherwise your centtral calendar will be the last month not the first

I do not know why, but today the search fails on tikiwiki.org with an sql error.
The problem was that the fulltext index was split into to; ft with pageName and data and description with description. In order to be able to do a fullsearch on the 3 columns, you ned to have a fulltext index on these 3 columns.

drop index ft on tiki_pages;drop index description on tiki_pages;create fulltext index ft on tiki_pages (pageName,description,data);

Use an url with delay=1000, the default is 3000
Or do to templates/tiki-browse_image.tpl and change the 3000 to your delay

Search in tikiwiki are not the best
I found an article about lucene

http://framework.zend.com/manual/en/zend.search.lucene.html
I will give a try

Sometimes, the mime type of a file is not well set. For instance a pdf file that can be application/pdf (but also application/download or application/force-download or application/x-download or...) has been recognized by the server as text/html. Sorry I do not know yet why - but it happens. Such file will open directly in the browser. Change the mime type in the database and it will popup again

If you want to write a php script using tikiwiki

define('TIKI_PATH', '/var/www/localhost/htdocs/tiki');
chdir(TIKI_PATH);
include('tiki-setup.php');

If for instance you have a wikiplugin that returns a string 11:48PM, this will be interpreted as a link. So it is important to return the plugin data surrounded with ~np~ .... ~/np~ . This wiki tags tells tikiwiki not to do further parsing on the string.
