Re: Difficulty understanding interpolation

The only way I was able to do it was by creating global subs in
minivend.cfg.

Example:

This code would go in your html doc.  It would call a global sub routine
called "get_searchspec", which would pass the value of mv_searchspec.

[perl arg=sub interpolate=1]
get_searchspec( [value mv_searchspec] )
[/perl]


This goes in minivend.cfg


GlobalSub <<EOT
sub get_searchspec {

# Read in the value of mv_searchspec
my (@search_stuff) = @_; 

# Turn $search_stuff into scalar $company
my $company = ($search_stuff); 

# Turn $company into a scratch variable [company]
$Vend::Session->{'scratch'}->{'company'} = $company;

return;
}
EOT


Then in your html, [scratch company] will return the value of
mv_searchspec. (In theory)

I say "In theory" because is took my about 3 weeks to figure out how to
pass variable from Minivend to Perl Subs and then back out to Minivend.

It's a bitch Chris, but I did get it to work.  

[set] does not interpolate as far as I know, and I've been messing with
minivend for about 8 months consistently.

Maybe Mike will add that feature in.

Good luck.

Matt
