Question on param, and hashes

[Darren Greer <dg...@websightsolutions.com>]

Ok...

We have been using Embperl since b2.  I have just recently upgraded a
server to b4, and now I can no longer pass a hash as "param => \%param"
to Embperl::Execute.  I then installed b3 on the server to test it, and
the same problem occurs.  So, I re-installed b2, and all is well now. 
Is there something I am missing here?

Also, Is there a way to pass multiple hashes to the templates?

Any help would be appreciated,

Thanks,

Darren

This makes complete sense, and I will try it immediately.  However, I assure
you you can pass it by reference the way I tried in b2.  But it is a moot
point.  Thank you for the correction.

param takes a array ref and _not_ a hash ref. Embperl makes a alias between
the array you pass to param and the @param array inside the page and I could
not image how this could have worked. Also I am not aware that I have
changed anything between b2 and b3 for the parameter passing.

To pass an hash do

param => [ %hash ]

and inside your page

%hash = @param ;

but much mor effective is to simply pass the hash reference:

param => [ \%hash ]

and in the page

$hashref = $param[0] ;

This work also for multiple hashs:

param => [ \%hash1, \%hash2, \%hash3 ]

and in the page

($hashref1, $hashref2, $hashref3) = @param ;

Of course you can pas also other scalars, not only hashs.
