Hello,

just to add one possible option, there is a small module “matrix” that provides a data structure that might be handy in this case.

https://www.kamailio.org/docs/modules/devel/modules/matrix.html

Of course it can be also done by serializing the data in a htable or similar.

Cheers,

Henning

Subject: [SR-Users] Multi-dimensional data in htable

What’s the best way to store multi-dimensional data within an htable?  For example, storing an avp stack:

$avp(foo) = "first";

$avp(foo) = "second";

$sht(bar=>foo) = $avp(foo);

The result of which is that only $avp(foo[0]) is stored in the htable:

kamcmd htable.dump bar

{

        entry: 2

        size: 1

        slot: {

                {

                        name: bar

                        value: second

                        type: str

                }

        }

}

The htable documentation shows support for lists, but it doesn’t make clear if this is really usable outside of loading from a database, and looks like it’s short hand for managing/creating linked lists.  The other option would be to simply serialize the data before storing it in the htable – which is fine, I just want to be sure I’m not overlooking a more convenient method.
