Debugging Tips
 

DEBUGGING WITH WPM()
Included with the library is an HTML-based variable debugger, wpm().  You can use it
to display pretty, click-able details about any variable.

Ex:  

  wpm($result);  

EXCEPTIONS
Sometimes exceptions happen, which are not appropriate to display with wpm() (the default).
You can tell your $client to use print_r instead.

Ex:

  $client = new CreditCardTransactionClient();
  $client->bool_output_exceptions_as_print_r = TRUE;

GETTING ACTUAL XML SENT AND RECEIVED
Sometimes for debugging, 3DSI needs to see the actual XML which was sent or received.
You can do this if you set the $setLastXmlValues = TRUE on the callClientMethod function.

Ex:

  $client = new CreditCardTransactionClient();
  ...
  $result = $client->callClientMethod("AuthorizeAndCapture", $params, TRUE);
  // (notice the last parameter is TRUE).

  // We may now access or log: $client->lastXmlResponse, and $client->lastXmlRequest
