A couple easy things to check right off...
(1) Make sure you have $FmtPV declared as a global in your function
(2) Make sure your markup rule is ordered such that the changes you
are making occur before they are used (i.e., '<{$var}' or before, use
?action=ruleset with diag turned on to confirm the order)
Many thanks for you quick answer - but...
(1) I´m declaring $FmtPV as a global in my cookbook-script (se below).
(2) I think I don´t understand what you are
saying. :) I don´t user Markup() to set the
variable in any way - only to create the function
that sets the variable.... So where and how should I use the '<{$var}' ?
In short my setup looks like this;
my_cookbook.php
========
Markup('my_function',
'_begin', '/\\(:my_function(.*?):\\)/e', 'main_function("$1")');
global $FmtPV;
function main_function( $opts )
{
{ code that set $ToMyVariable to what it should be... }
$FmtPV['$MyVariable'] = '$ToMyVariable'';
return;
}
========
In config.php
========
include_once("$FarmD/cookbook/my_cookbook.php");
========
On the PmWiki-page
========
(:my_function:)
{$MyVariable}
========

Thomas.
