Question

Is there any way to get from a HASH() value to the actual value of some meta data in a plugin Perl module?

This code: my $status = $meta->get( 'FIELD', 'Status' );

Returns a string "HASH(0x...)" that is presumably a look-up into a metadata store.

Or maybe there is a better way to get form field data from a topic in a plugin? The documentation on access to metadata is a bit sketchy.

Answer

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

The result of that call is a hash containing the information for the field "status". This information has the following fields:

• name - the name of the field
• attributes - Any special attributes as declared in the form definition ("H" for hidden, etc)
• title - How it's displayed, usually the same as name
• value - the actual value of the field

So, if you need the value of a form field, what you need to do is:

my $field = $meta->get( 'FIELD', 'Status' );
my $status = $field->{value};

Each kind of META has its own structure. The best way to learn it is to see the topic txt file.
