Variables and Conditional Parser Functions
It must be noted that everything in conditionals gets executed (though only one result gets displayed). Because of this, every instance of #vardefine will always get executed, regardless of to what the conditional gets evaluated.

Given the following:

gives prevvalue.

Instead you have to nest the conditional inside #vardefine:

In this case, gives nextvalue.

Multiple assignments
It would be good if this extension allowed multiple assignments. Say I have a template data that contains a=1|b=2. I call and usedata gets one template-variable, a, with value 1|b=2. If I could make data say a=1,b=2 and usedata could call variablesextension to set both variables at once, that would be useful.--201.216.136.95 18:24, 10 January 2007 (UTC)

Bugzilla request
The bug requesting this to be added for the big sites (wikipedia, etc.) is 8570. If you really want these functions, go (register and) vote for that bug. If you have an concern, that bug would also be an appropriate place to express it.--201.216.136.95 18:24, 10 January 2007 (UTC)

MediaWiki version 1.9
How is the compability with MediaWiki version 1.9?

use of undefined variables
Sometimes you want to use a variable which has not been set before and you expect it to return an empty string. I suggest to change the code of function "varf" as follows: function varf( &$parser, $expr = '' ) { if (isset($this->mVariables) && array_key_exists($expr,$this->mVariables)) return $this->mVariables[$expr]; return ''; }

Number incrementing through page
I'm trying to write a template, two templates in fact, that will increment a number through a page, ie. @undefined @undefined @undefined

@undefined @undefined

@@ starts the counter at 1 and prints it and @ increments the number and prints it.

I expect the following to appear: 1 2 3 4 1 2 3

But I get the following: 1 2 2 2 1 2 2

I'm using the following code for the templates.

Template: @@

Template: @

Thanks.

 * Your problem is that variables don't persist across templates, so you need to pass the value of n from @@ to @. So, your page needs to be:

@undefined @undefined @undefined

@undefined @undefined

@undefined @undefined @undefined
 * On a 1.12 version of MediaWiki, I get 1 2 3 4 1 5 6 which is not what was expected, but:

@undefined @undefined gives (to me): 1 2 3 4 1 2 3. --Nbrouard 14:38, 25 June 2008 (UTC)

@undefined @undefined @undefined

@undefined @undefined is also working with the new parser. --Nbrouard 15:14, 26 June 2008 (UTC)

Multiple inclusions in a template, still counting
Let funcone be the following template: @undefined @undefined @undefined @undefined Inclusion of content

Redefining n for second inclusion

@undefined @undefined Second inclusion of content

after second content

Trying on the following wiki text: Testing Funcone

@undefined

I get:
 * Testing Funcone 1 2 3 4 5 Inclusion of content 6 7 8 9 10 Redefining n for second inclusion
 * 37 38 Second inclusion of content 6 7 8 9 10 after second content 39

instead of:
 * Testing Funcone 1 2 3 4 5 Inclusion of content 6 7 8 9 10 Redefining n for second inclusion
 * 37 38 Second inclusion of content 39 40 41 42 43 after second content 44

Any idea to make substitution earlier? --Nbrouard 13:10, 30 June 2008 (UTC)
