Code

function commerce_bpc_get_combinations($form, &$form_state) {

  // We need the cartesian product of the arrays in $options.
  // In order to do that, we loop through these arrays, at every
  // stage taking the cartesian product of the actual array with
  // what is there already. So after the first iteration,
  // $combinations will just be the first member of $options.
  // After the second, it will be the product of this with the
  // second member, after the third, we will have the product
  // of the previous product with the third member, and so on.
  //
  // Initialize with an empty array as sole member, so that the first
  // iteration has something to work with.
