FormProcessor - display form values in confirmation chunk

Using FormProcessor, I need to display some of the values submitted in the original "form_chunk" in the "confirmation_page_chunk"

I’ve tried without luck using two snippets stuck at the top of the "form_chunk" and "confirmation_page_chunk":

[!formSave!] at top of form_chunk
<?php
session_start();
$_SESSION[’EventTitle’] = trim($_POST[’EventTitle’]);
etc
?>

[!formRetrieve!] at the top of confirmation_page_chunk
<?php
$modx->setPlaceholder(’EventTitle’, $_SESSION[’EventTitle’]);
etc
?>

The snippet call looks like this:

[!FormProcessor? &form_chunk=`submitCalendar` &data_email_address=`[email protected]` &form_required=`Name,Description,Address,PhoneArea,Phone,Email,EventTitle,DateBegins,CompanyName,Address,CityStatePostcode` &data_email_subject=`Calendar Listing Request` &confirmation_page_chunk=`submitCalendarConfirmation`!]

Not sure why it won’t work - can I use a snippet within a snippet?

Mostly harmless.

Is it possible that the first form is writing the $_SESSION variables before their values exist?

Have you tried just echoing the $_SESSION variables in a snippet in the second document to make sure they’re set correctly?

Yes, you’re right. The second doc should have [!formSave!] at the beginning and then possibly the formRetrieve code within the same snippet, however the snippet doesn’t work in the chunk as I can see "[!formSession!]" (the new snippet) displaying at the top of the content area!

If I simply put [+EventTitle+] in the confirmation_page_chunk somewhere no value displays.

[!formSession!]

<?php
session_start();
$_SESSION['EventTitle'] = trim($_POST['EventTitle']);
$modx->setPlaceholder('EventTitle', $_SESSION['EventTitle']);
?>

Mostly harmless.

$output = $modx->getChunk('chunk_name');
return ($output);
?>

I think MODx is retrieving the chunk before the snippet executes. Can you use the code above in the second snippet instead? That should put things in the correct order.

Sorry, don’t quite understand. What’s does "chunk_name" become?

I’ve change the name of the second snippet to [!formSession!] with your code and put that at the top of FormProcessor’s "confirmation_page_chunk" but it’s still not executing it:

[!FormProcessor? &form_chunk=`submitCalendar` &data_email_address=`[email protected]` &form_required=`Name,Description,Address,PhoneArea,Phone,Email,EventTitle,DateBegins,CompanyName,Address,CityStatePostcode` &data_email_subject=`Calendar Listing Request` &confirmation_page_chunk=`submitCalendarConfirmation`!]

submitCalendarConfirmation:

[!formSession!]
<p class="introtext">
Thanks for submitting your event listing for [+EventTitle+].
</p>
<p>Please proceed to PayPal to make your payment. Event listings will only be posted once payment is confirmed.</p>
<br />
<form method="post" action="https://www.paypal.com/cgi-bin/webscr">
<fieldset>
<legend>Payment</legend>
<p>All payment transactions are carried out securely via PayPal using Mastercard and Visa.</p>
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="add" value="1">
<input type="hidden" name="business" value="[email protected]">
<input type="hidden" name="item_name" value="[+EventTitle+] - Event Listing">
<input type="hidden" name="item_number" value="LIST">
<input type="hidden" name="amount" value="79.00">
<input type="hidden" name="currency_code" value="AUD">
<input type="hidden" name="return" value="http://www.mydomain.com.au/thank-you">
<input type="hidden" name="undefined_quantity" value="1">
<button type="submit" name="submit" class="cart" value="Submit">Proceed to payment</button>
</fieldset>
</form>

formSession:

<?php
session_start();
$_SESSION['EventTitle'] = trim($_POST['EventTitle']);
$modx->setPlaceholder('EventTitle', $_SESSION['EventTitle']);

$output = $modx->getChunk('chunk_name');
return ($output);
?>

Mostly harmless.

chunk_name should be replaced by the name of the chunk you create. That chunk would hold this:

<p class="introtext">
Thanks for submitting your event listing for [+EventTitle+].
</p>
<p>Please proceed to PayPal to make your payment. Event listings will only be posted once payment is confirmed.</p>
<br />
<form method="post" action="https://www.paypal.com/cgi-bin/webscr">
<fieldset>
<legend>Payment</legend>
<p>All payment transactions are carried out securely via PayPal using Mastercard and Visa.</p>
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="add" value="1">
<input type="hidden" name="business" value="[email protected]">
<input type="hidden" name="item_name" value="[+EventTitle+] - Event Listing">
<input type="hidden" name="item_number" value="LIST">
<input type="hidden" name="amount" value="79.00">
<input type="hidden" name="currency_code" value="AUD">
<input type="hidden" name="return" value="http://www.mydomain.com.au/thank-you">
<input type="hidden" name="undefined_quantity" value="1">
<button type="submit" name="submit" class="cart" value="Submit">Proceed to payment</button>
</fieldset>
</form>

Which you’d remove from the document (since it will all be returned from the snippet -- hopefully, with the placeholders properly filled).

I hope I understand what you’re trying to do. I’ve never used FormProcessor so I’m guessing here, and there may be an easier way to do what you want.

i think the problem is the snippet calls a chunk which has a snippet in it. ie FormProcessor snippet calls the confirmation page chunk`submitCalendarConfirmation` which in turn has the [!formSession!] in it plus the rest of the chunk code.

[!FormProcessor? &form_chunk=`submitCalendar` &data_email_address=`[email protected]` &form_required=`Name,Description,Address,PhoneArea,Phone,Email,EventTitle,DateBegins,CompanyName,Address,CityStatePostcode` &data_email_subject=`Calendar Listing Request` &confirmation_page_chunk=`submitCalendarConfirmation`!]

Mostly harmless.

Ok, I’ve looked at the FormProcessor snippet. If I understand you correctly, you just have some user input from the original form that you’d like to display on the confirmation page. If that’s the case, you shouldn’t need $_SESSION variables at all or any extra snippets.

FP creates a form that posts to itself. The first time it’s called, it just displays the form with the render_form() function, which simply displays the chunk you specify as holding the form. Presumably, your input fields are in that form.

On the second pass (post-back), it optionally

Creates the DB if it doesn’t exist (check_database() )
Writes to the DB (write_database() )
Emails the results (email_data() )
Displays the confirmation page (render_confirmation() )

Since the data you want to display is present in the $_POST array, all you should need to do is to set your placeholders at the very beginning of the render_confirmation() function. Remember that placholders are case-sensitive so they have to match the placeholders in your confirmation chunk.

IOW, replace this part of the render_confirmation function:

if($confirmation) {

  // Return the confirmation chunk
  $html = '{{'.$confirmation.'}}';

 } else {

with this:

if($confirmation) {

   // set my placeholders
   $modx->setPlaceholder('EventTitle', trim($_POST['EventTitle'] ));


  // Return the confirmation chunk
  $html = '{{'.$confirmation.'}}';

 } else {

If you need the placeholders set in the email also, you’ll need to do the same thing in the email_data() function.

That should do it. Hope this helps.

The email processed ok, but the return screen was blank...

Mostly harmless.

A blank screen usually means an HTML or PHP syntax error on the page. Do you see anything with "view source" on that page?
