how do I store/retrieve a hash through Apache::Session?
Maybe a silly question...
how do I store/retrieve a hash through Apache::Session?
This doesn't work...
# retrieve
%table=$session{table};
...
# store
$session{table}=%table;
What's my fault?

You can only store/read references:
my %table = (this = 'that' );
$session{table} = \%table;
...
my $table = $session{table};
foreach my $key ( keys %{ $table } ) {
print "$key = $table-{ $key }\n";
}
see 'perldoc perlref' for much more on references.

store hash references, not hashes.
This doesn't work...
# retrieve
%table=$session{table};
$tableref = $session{table};
...
# store
$session{table}=%table;
$session{table}= \%table;
or, preferably:
my $tableref = {};
# add stuff to table
# ...
$session{table}= $tableref;
What's my fault?

You need to store/retrieve it as a ref-
\%my_hash

Re: how do I store/retrieve a hash through Apache::Session?
Once you realize that %session entries have to be scalars (references) as
described by other responses, be sure when you change entries in the
sub-hash that you tell the top-level session that the data's been changed
(it won't realize it unless you change one of its scalars).
Check the docs or the archives for the "official way" to do this (a message
from Jeffrey Baker uses such a phrase), but any modification of a %session
scalar will do - $session{_changed}++; , f'rinstance.
Best,
Randy
