Question

In a web we have groups of topics that have their own project theme. They don't merit a separate web but we would like to be able to have a different leftbar for each group.

So if a parent topic has many child topics we would like the child topics to inherit the parent's leftbar.

Using INCLUDE and/or IF/ELSE how can I do the following?

If parentsleftbar exists include it

else include defaultleftbar

I'm making some progress by am having trouble resolving variables

I get the parent of the topic using this search.

   * Set MYDADDY = %SEARCH{ "^%BASETOPIC%$" scope="topic" nosearch="on" type="regex" nototal="on" format="$percntCALC{$IF($EXACT($parent,), %HOMETOPIC%, $parent)}$percnt" }%

I then set a variable for the parents left bar topic

   * Set DADDYLEFTBAR = %MYDADDY%LeftBar

The problem is then including this topic as the following does not work

%INCLUDE{"%DADDYLEFTBAR%" warn="off"}%

Even the Im only 1/2 way there as I really need something like

%INCLUDE{"%DADDYLEFTBAR%" warn="%INCLUDE{"%PROJECTLEFTBAR%" warn="LeftMenuBar"}%"}%

Any ideas?

Suppose you have a default WebLeftBar and a MyTopicWebLeftBar. This search will find the parent of the current topic, and writes it inside an INCLUDE. The 'WebLeftBar' is appended - if nothing is found only 'WebLeftBar' is included:

%INCLUDE{"%SEARCH{ "^%BASETOPIC%$" scope="topic" nosearch="on" type="regex" nonoise="on" format="$parent" }%WebLeftBar"}%

Thanks Arthur, this is what I was looking for.

In our case the SEARCH command goes into WebLeftBar, so I had to modify it to avoid rec curing inserts of WebLeftBar itself.

So I have a parent topic TheParent that has a corresponding left bar TheParentLeftBar. All children topics of TheParent inherit the left bar with

%INCLUDE{"%SEARCH{ "^%BASETOPIC%$" scope="topic" nosearch="on" type="regex" nonoise="on" format="$parent" }%LeftBar"}%
