sending attribute value to payment processor

[DrByte]

I've looked into ways that others have retrieved attribute information and modified some of the Linkpoint code:

<?php
function before_process() {
    global $order, $db;
    $myorder = array();

	if (isset($order->products[$i]['attributes'])) {
			for ($j=0, $m=sizeof($order->products[$i]['attributes']); $j<$m; $j++) {
			  $myorder["items"][$i]['options' . $j]['name'] = $order->products[$i]['attributes'][$j]['option'];
			  $myorder["items"][$i]['options' . $j]['value'] = $order->products[$i]['attributes'][$j]['value'];
			}
		  }
	$attrib = $order->products[$i]['attributes'][$j]['value'];
	
}
?>
Your Attribute value is <?php echo $attrib;
?>

I would suggest that that's the right snippet of code to work from, perhaps like this:

<?php

function before_process()
{
  global $order;
  $erpNumber = '';
  if (isset($order->products[$i]['attributes']))
  {
    for ($j = 0, $m = sizeof($order->products[$i]['attributes']); $j < $m; $j ++)
    {
      if ($order->products[$i]['attributes'][$j]['option_id'] == 28) {
        if ($order->products[$i]['attributes'][$j]['value_id'] == 77) {
          $erpNumber = $order->products[$i]['attributes'][$j]['value'];
          break;
        }
      }
    }
  }
}
?>
Your Attribute value is <?php echo $erpNumber;  ?>

That check is based on options_id 28 and values_id 77. It's going to be much more complicated to go based on products_attributes_id.
Adjust the 77 according to your data.
