Question

Is it possible to %INCLUDE% one topic into an other but also sending an URL parameter to the included topic?

Example: I've got a topic called WhatsNew which shows the recent changes of a web. This topic accepts the URL parameter limit to set the number of recent changes to be shown (.e.g WhatsNew?limit=20). In our setup, I use this topic in all our webs with an %INCLUDE% statement which works fine.

Depending on the situation, I would like to see a different number of changes displayed, hence I would have to be able to use the URL parameter in the %INCLUDE% statement. However, if I do that, I get the following error message:

 Warning: Can't find topic General.WhatsNewlimit=10

Any ideas?

Thanks for your help.

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

I am not quite sure what you are trying to achieve because how to include another topic with parameters is documented in TWiki.VarINCLUDE. Maybe you just need a pointer to an example? It has been added only recently to the documentation for the upcoming TWiki 4.2 release, see the fourth example in TWiki04x02.IncludeTopicsAndWebPages.

I Think what you are wanting is what I did with the BugsContrib - see http://develop.twiki.org/~twiki4/cgi-bin/view/Bugs/Tabulator?raw=debug .

The Tabulator topic is included into a variety of topics in that Bugs web to generate query results, and that is driven either by INCLUDE params (via URLPARAM's default), or over-ridden by the URLPARAM

Thanks! These two answers helped me to understand what I should have understood before.

Just for the record, here is what I did. I adjusted the topic WhatsNew to include the %LIMIT% variable and set it to a default value.

%SEARCH{".*" web="%INCLUDINGWEB%" type="regex" nonoise="on" order="modified" limit="%URLPARAM{"limit" default="%LIMIT%"}%" reverse="on" excludetopic="Web*" format="| [[%INCLUDINGWEB%.$topic][$topic]] | $date | $percntCALC{$IF($rev > 1, r$rev, $percntN$percnt)}$percnt | $wikiusername |" }%
<!--
   * Set LIMIT = 5
