I'm implementing civi_relate_civicrm_postProcess and trying to capture some Custom data fields in order to pass them along to civicrm_contact_add API, but although I can at least get an array of the _elements:
    foreach ( $form->getVar('_elements') as $key => $value ) {
      print_r($value);
        }
but I'm trying to get a custom field called Parent/Guardian firstname further down in _elements array 
...
[_values] => Array (

• => 1012 ) [_label] => State (Primary) [_type] => select [_flagFrozen] => [_persistantFreeze] => 1 [_attributes] => Array ( [name] => state_province-Primary ) [_tabOffset] => 0 [_tab] => [_lineEnd] => [_comment] => ) [10] => HTML_QuickForm_text Object ( [_label] => Postal Code (Primary) [_type] => text [_flagFrozen] => [_persistantFreeze] => 1 [_attributes] => Array ( [maxlength] => 12 [size] => 12 [name] => postal_code-Primary [type] => text [value] => 60035 ) [_tabOffset] => 0 [_tab] => [_lineEnd] => [_comment] => ) [11] => HTML_QuickForm_text Object ( [_label] => Parent/Guardian First Name [_type] => text [_flagFrozen] => [_persistantFreeze] => 1 [_attributes] => Array ( [name] => custom_12 [type] => text [value] => Betty )

 ...
but I can't come up with a way to capture specifically [name] => custom_12 [type] => text [value] => Betty ) into a variable.

no specific reason not to have done exactly as suggested, short of lacking the good sense at the late night last night to have done what I believe would have been a well advised reading of the fine manual at:
http://pear.php.net/manual/en/package.html.html-quickform-controller.php

This code by way of example is looking to allow me now to get exactly the variables I need:
       $params = $form->controller->exportValues( $form->getVar( '_name' ) );
       $parent_first_name = CRM_Utils_Array::value( 'custom_12', $params );
       print("$parent_first_name");
       $parent_last_name = CRM_Utils_Array::value( 'custom_13', $params );
       print("$parent_last_name");

a million thanks and a thousand more!
