[FX.php List] FX and Editing Global Fields

[Bradley Creamer]

Hi Karstyn,

Here's the instruction set from the "Function Reference for FX.php":

SetFMGlobal ($globalFieldName, $globalFieldValue)
This function is FileMaker 7 specific and is equivalent to appending 
".global" to a field name in order
to set a global field. In order to ensure that a global is set in 
FIleMaker 7 (before performing a script,
for example), use this function instead of AddDBParam() to set the 
global field.

 >> The $globalFieldName parameter should contain the name of the 
FileMaker global field to be
set.

 >> The value passed via $globalFieldValue will be stored in the 
specified global field before other
FileMaker actions are performed.

That's all I can find. So, my expectations of this function is to "set" 
the global field permanently regardless of session. I know that FMP11 
handles things much differently than FMP6, but why would the DB reset 
the value of a global field when it's asked so specifically change that 
value?

Regardless of my intent, where does it say globals are set on a 
per-session only, then revert?

I did find this from FileMaker's CWP documentation:


For direct XML requests and requests made via XSLT stylesheets that 
don't use sessions, the global values expire immediately after the 
request is made. For requests made via an XSLT stylesheet that use 
sessions, the global values persist for the duration of the session 
defined in the stylesheet, or until they are changed again with another 
request.

I seriously don't understand this behavior. Does anyone know of a 
work-around that makes the NEW global field value persist using XML?

Thanks,
Bradley
