livedocx, mergeblocks and Session variables

[itachi77]

Hi, seem to be having trouble with mergeblocks with livedocx in php.  I understand that for merge blocks a multi associative array is needed such as :

 

    $billConnections = array(
    array(
        'con_productid'   => 1A,
        'con_quantity' => '10',
        'subtotal' => '£10',
    ),
    array(
        'con_productid'   => '1B',
          'con_quantity' => '20',
        'subtotal'     => '£30',
    ),
);

 

This does print two rows on the document, however i am struggling to understand how to transfer SESSION variables into those 3 fields.

I have tried:

$array1=unserialize($_SESSION['product']);

while(list($vs,$ks)=each($array1))
$billconnections=array(
array('con_productid'=> $ks));

But this only seems to print one row not for all the product id's stored in the session variable.  I know session array itself is an associative array but i'm getting confused with how to specify the different fields with it.  Any help appreciated, thanks
