SID-01888: Conditional INCLUDE not working as expected

Status:	Answered	TWiki version:	6.0.0	Perl version:
Category:	CategoryApplications	Server OS:	Mac OS X	Last update:	11 years ago

I have the following code in my TWiki/WebTopBar

   * %IF{ "$action~'*Hide*'" then="$percentINCLUDE{\"Help/HideWebLeftBar\"}$percent" }%
<form name="hideshow" action="%SCRIPTURLPATH{"view"}%/%INCLUDINGWEB%/%INCLUDINGTOPIC%" method="get">
<input type="hidden" name="hideleftbar" value="1" />
<input type="image" src="%PUBURL%/%USERSWEB%/DocumentGraphics/%IF{ "$action~'*Hide*'" then="showleftbar.png" else="hideleftbar.png" }%" title="%IF{ "$action~'*Hide*'" then="Show Left Bar" else="Hide Left Bar" }%" name="action" value="%IF{ "$action~'*Hide*'" then="Show Left Bar" else="Hide Left Bar" }%" />
</form>

The code runs when I click on the image. However, the conditional INCLUDE does not work as expected/documented.

When the first IF fires (i.e. when $action~'*Hide*') instead of including Help/HideWebLeftBar, it prints the string

$percentINCLUDE{\"Help/HideWebLeftBar\"}$percent

Discussion and Answer

Not sure. In any case, I think it is better to use some jQuery magic to toggle the sidebar. This is much faster because there is no need for a server round-trip.

If I was a lot better at JQuery, that might make sense. But the code runs in Foswiki (and I like pure TWiki examples.

Given that this use of INCLUDE is documented in If Statements, I think this is a bug.

It prints $percentINCLUDE because the syntax is $percnt, not $percent.
