Solution to avoid re-entering form data if server returns an error?

[Mike Hondel]

I've created a form similar to FaaS Example 2 (simple radio button form), and it seems to work great so far. My concern is with error handling.

I know that I can install client-side validation to ensure that all required fields are filled before the user can submit the form. But if the submission generates a server-side error (say, due to an incorrect credit card number), it seems thatonly the error comes back (via OnErrorUrl) – and the user has to re-enter all of the form fields. So I'm looking for a way to help the user by re-populating the field data they already entered.

Is there any way to accomplish this with FaaS? A way to post via AJAX, perhaps? Or a way for C&P to attach a long query string to the OnErrorUrl (that contains all the field info the user entered)?

Thanks!

Good day!

Unfortunately at this time the system does not post back the answers or what is posted to it.

This is in the feature lists to be added to the next release of FaaS but currently there is no ETA. I will discuss this with the developers and let you know.

Thanks for the prompt response. Just to be certain: it seems that what I want to achieve (saving the user from having to re-enter the entire form after a server-side error) would be possible with PaaS, correct? I'm not sure I want to go that route (due to minimal experience w/ web services), but I want to best advise my client. Thanks in advance for your reply.

Good day Mike,

Please see the following release note:

http://forums.clickandpledge.com/showthread.php?648-FaaS-Release-1-29-Introducing-Postback-response-method-Post-or-Get&p=1904#post1904

With the addition of Postback method to the FaaS forms the system will post back all posted information back to the response pages. Using a dynamic page you may simply get all the posted data back and show them as the default values of the form fields.

Please note that the following information will NOT post back due to security reasons:

• Credit card number
• CV2

We hope this feature will help you with accomplishing what you were trying to do.

Post back to this thread and let us know how it works out.

Thanks for implementing FaaS postback (onError). It works great, and is a huge usability improvement.

I really appreciate your responsiveness.

Yes, I think it's a very common use-case when people choose FaaS, they will have a form page in their site which directly post user inputted data to Click&Pledge service; so when FaaS post back to the service response page, it's very important it send back all those user inputted data.

I just noticed one small problem:

When FaaS post back all the user inputted fields, seems RefID was duplicated ( other variables are fine) , I printed all the POST variables in my OnSuccessful page:

keyn val:12422204154644111
key:vg val:7cfd74ea-366a-4f84-ae08-f668418d6b3a
key:au val:dc260f
key:gn val:1701cedd-0d01-40fb-b4b3-3b54be004d5e
key:RefID val:xx.xx.xx.162-1335141682-fc8129eddd9c7116904d32abba0618e1,xx.xx.xx.162-1335141682-fc8129eddd9c7116904d32abba0618e1

Good day!

Please post the form URL here so we can review your form. I just want to make sure you don't have 2 nodes called RefID.

try this one : http://therealnews.com/t1/t1.php



the return.php code:
<?
function PrintPost()
{
foreach ( $_POST as $key=>$value)
{
print "key:$key val:$value<br>";
}
}


PrintPost();
?>
