I'm using hosted payment page, here system redirects to nab transact page for payment and displays receipt page after transaction approved.
I set the return_link_url and reply_link_url in input hidden variables as below.
<form action="https://demo.transact.nab.com.au/live/hpp/payment" method="post" id="payment">
<input type="hidden" name="vendor_name" value="XXXXXXX" />
<input type="hidden" name="payment_alert" value="xx#xx.com.au" />
<input type="hidden" name="print_zero_qty" value="false">
<input type="hidden" name="return_link_text" value="Click Here to Return to the Home Page">
<input type="hidden" name="return_link_url" value="http://www.mysite.com.au/index.php?route=payment/nabtrans/callback&order_id=51216" />
<input type="hidden" name="reply_link_url" value="http://www.mysite.com.au/index.php?route=payment/nabtrans/callback&order_id=51216" />
<input type="hidden" name="Pay for Order number 51216" value="22" />
<input type="hidden" name="payment_reference" value="51216" />
<input type="hidden" name="Name" value="XXX XX" />
<input type="hidden" name="information_fields" value="Name">
The problem is the reply_link_url is not getting triggered automatically at the time payment receipt page is displayed to customer as mentioned in guide.
I tried with appropriate cgi handler which does executes if called. So, I used them in the reply link url, but still the link doesn't triggered automatically.
<input type="hidden" name="return_link_url" value="http://www.mysite.com.au/cgi-bin/handler.cgi?orderid=51217" />
<input type="hidden" name="reply_link_url" value="http://www.mysite.com.au/cgi-bin/handler.cgi?orderid=51217" />
I have to click on return link on payment receipt page to come back to website. The reply_link_url never triggered automatically after the receipt page displayed in 15 sec timeout. I made sure to use http in reply link url to make it listening on port 80. The CGI script executes if I run it in browser.
Solved
I used two different url's for reply_link_url and return_link_url.
They are
<input type="hidden" name="return_link_url" value="http://www.mysite.com.au/index.php?route=payment/nabtrans/replyback&order_id=51216" />
<input type="hidden" name="reply_link_url" value="http://www.mysite.com.au/index.php?route=payment/nabtrans/callback&order_id=51216" />
I made sure to add the code inside callback function to execute the background process after payment approves and used code for redirecting to payment success page inside replyback function. Both these functions reside in nabtrans controller. As I noticed the the reply link triggers automatically which executes the background processes to update order, but the last step of displaying the checkout/success page never bring the link from payment success page of nabtrans to the original website. Still I was happy all background tasks done. So, I used the return link for coming back to original website. This solves the purpose completing transaction and coming back to website.

I implemented a paypal checkout about 3 years ago and it is currently working well. I now want to create a new checkout page for a new set of items. I copied the code from the page that I previously used and updated it for the new items. I set up the new page to use my sandbox for initial testing. The code below is cut from the actual page for display here.

The code works and creates an order in the paypal sandbox. It is then supposed to go the the url in the "return' item, which it does. The problem is that paypal is supposed to return a bunch of data in $_POST. When the return page is displayed, $_POST is empty. I also display $_GET and it contains 1 field which is the payer_id. A couple of questions...
Anyone know why no data in $_POST?
Is there a way that I can get any kind of error message that shows info on why no POST data was sent when going to the url in the return item?
I assume that this method of using paypal is deprecated. Is there a place that I can still get to the docs for using this interface?
The receiving sandbox Business account needs to enable Payment Data Transfer for any data to be returned.
With this sort of HTML-only (no API) PayPal integration that redirects away from your site, a return after a completed transaction is never guaranteed to occur. PayPal may be obligated to show the payer a receipt, or they may never click to return, or their browser may be closed or crash. Therefore, you should not depend on this returned data for absolutely anything of any importance. It is for extra informational purposes only.
If you are trying to do anything important with data returned via _GET/_POST , your integration is flawed.
With such an HTML-only <form> post integration, the only reliable way to receive data is by implementing the IPN service, which is also very old. All of these are poor choices if you need to do anything important with the data being returned.
Instead, use a current PayPal Checkout integration. Follow the Set up standard payments guide and make 2 routes on your server, one for 'Create Order' and one for 'Capture Order', documented here. Both routes should return only JSON data (no HTML or text). Inside the 2nd route, when the capture API is successful you should store its resulting payment details in your database (particularly purchase_units[0].payments.captures[0].id, which is the PayPal transaction ID) and perform any necessary business logic (such as sending confirmation emails or reserving product) immediately before forwarding your return JSON to the frontend caller.
Pair those 2 routes with the frontend approval flow: https://developer.paypal.com/demo/checkout/#/pattern/server
I am trying to send passthrough data in a paypal paynow button and have paypal return that data to my php page when user clicks “return to merchant” button after paying.
For this I am using the “return” facility in the paypal button, together with rm=2 to send all the data back as post. However, I cannot get it to work. Here is my paypal button html:
<form name="paypal2" action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="xxx">
<input type="hidden" name="invoice" value="testinvoice_fromcode2">
<input type="hidden" name="custom" value="testcustom_fromcode1">
<input type="hidden" name="on0" value="yes"><!--agreetc-->
<input type="hidden" name="os0" value="<?php echo $aid; ?>">
<input type="hidden" name="on1" value="<?php echo $id; ?>">
<input type="hidden" name="os1" value="<?php echo $agent; ?>">
<input type="hidden" name="return" value=http://www.example.com/Admin/conpanel/privat/phpvendorpaidad.php>
<input type="hidden" name="rm" value="2">
<input id="submit" type="image" src="https://www.paypalobjects.com/en_GB/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="PayPal – The safer, easier way to pay online!">
<img alt="" border="0" src="https://www.paypalobjects.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>
In the IPN notification, paypal renders:
os0 as option_selection1,
os1 as option_selection2,
on0 as option_name1,
on1 as option_name2,
I know that on0 and os0 are supposed to be used as name value pairs but way back in 2009 when I first wrote this script there were only 2 sets allowed and therefore I used all 4 to carry values and it worked then.
But essentially, I cannot understand why
<input type="hidden" name="return" value=http://www.example.com/Admin/conpanel/privat/phpvendorpaidad.php>
<input type="hidden" name="rm" value="2">
is not working.
I cannot pick up these values in the receiving script, phpvendorpaidad.php, either as
$aid=$_REQUEST['option_selection1'];
or as
$aid=$_REQUEST['os0'];
for example.
Can anyone see what I am doing wrong? Much appreciated.
I also have an IPN listener page that is working normally. Could another way be to build this in to the IPN listener page using javascript to send the form data automatically on page onload?
Is paypal actually POSTing to your return script or using GET? In the latter case, you can see the txn_id and some other info in the query string, but you will NOT get the whole payment detail data.
If you have Auto Return set to On (meaning the user get automatically redirected back to your site, without having to click a button), then paypal with send a GET request and will include only a few items.
var_dump($_REQUEST) and var_dump($_POST) in your script to see what you are getting.
Actually the problem lay in defective if/else logic in my return code, which was set up in 2009 to handle the GET variables that Paypal was sending to the return script in those days. This logic had to differentiate between the POSTed data received from a preceeding form on my server and the GET data received from Paypal. Paypal appears to have chenged since 2009 and no longer sends GET data to the return script but POST data via
<input type="hidden" name="return" value=http://www.example.com/Admin/conpanel/privat/phpvendorpaidad.php>
<input type="hidden" name="rm" value="2">
Once this was corrected the program worked.
However, I was only able to discover the problem thanks to the brilliant suggestion from JBart to var_dump($_REQUEST) (or the more easily read print_r($_REQUEST)). Without this I would still have been floundering. So cheers JBart, would love to buy you a drink if you are in the neighbourhood (NW London)!
And no, I didn't need to extract any variables from the received POSTed array (see my last comment above), just normal '$payment_status = $_POST['payment_status'];'. In this I had misinterpreted another thread on the subject in "How can I get posted data passed along when the user is first redirected through Paypal?"
I'm using a plugin called USP Pro which allows users to publish posts on my Wordpress Site. Upon pressing the submit button to publish their post, the user is redirected to PayPal(whilst their submitted post is sent to my wordpress posts section to be reviewed and 'published'). However, if the user doesn't pay the fee their post will still be submitted, which needs to be prevented. I initially overcame this problem by redirecting the user to the PayPal page for payment before the submit button stage, and then redirecting them back to the form afterwards to press the submit button (which involved echoing the form inputs). However, the form includes file uploads which cannot be sent across multiple pages due to security restrictions, so the PayPal page has to be after the submit button is pressed.
Here is my form:
<form id="usp-form-990" class="usp-form" method="post" enctype="multipart/form-data" action="" data-validate="parsley" data-persist="garlic" novalidate>
<input name="usp-title" type="text" value="" data-required="true" required="required" maxlength="99" placeholder="Post Title" class="usp-input usp-input-title" />
<input name="usp-title-required" value="1" type="hidden" />
<textarea name="usp-content" rows="5" cols="30" maxlength="999" data-required="true" required="required" placeholder="Post Content" class="usp-input usp-input-content"></textarea>
<input name="usp-content-required" value="1" type="hidden" />
<input name="usp-files[]" type="file" maxlength="255" data-required="true" placeholder="File(s)" class="usp-input usp-input-files select-file multiple" multiple="multiple" id="usp-multiple-files" />
<input name="usp-file-limit" class="usp-file-limit" value="20" type="hidden" />
<input name="usp-file-count" class="usp-file-count" value="1" type="hidden" />
<input name="usp-files-required" value="0" type="hidden" />
<input type="submit" class="usp-submit" value="Publish" />
</form>
Here is the PayPal button that is used:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="5F498FHQQGRR2">
<input type="image" src="http://www.aeroex.co.uk/wp-content/themes/vantage/paybutton.gif" border="0" name="submit" alt="PayPal – The safer, easier way to pay online.">
<img alt="" border="0" src="https://www.paypalobjects.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>
I don't know if this will help, but I found this code to prevent this exact issue but for another forms plugin called Formidable Pro. Due to my inexperience with PHP and coding in general, I have found myself unable to customize this code to suit my requirements.
add_action('frm_payment_paypal_ipn', 'publish_paid_post');
function publish_paid_post($args){
if(!$args['pay_vars']['completed'])
return; //don't publish if the payment was not completed
if(!$args['entry']->post_id)
return; //don't publish if not linked to a post
wp_update_post(array('ID' => $args['entry']->post_id, 'post_status' => 'publish'));
}
My other attempts to solve this:
-saving user file uploads to wordpress directory and then retrieving them at the submit stage (unsuccessful)
I would suggest the flow to be: Put every thing user submitted with a "Draft" status, and implement an IPN(Instant payment notification) script to read PayPal payment call-backs, then update the WP database to change the post status from "Draft" to "Published"
The payment return/redirection should not be relied on in this case as when client browser is closed before auto-return, the process breaks. While IPN is the async message POST for a payment status, that's something you should use for processing the USP posts.
Not sure if there's any setup available in the USP Pro plugin but here's an sample IPN script which you may customize with your WP database update codes.
Formidable Pro has a PayPal extension that will do this. You build your user-submission form, then in form settings you add a PayPal action and fill in the necessary details. You also add a 'Create Post' action and use the conditional logic options to only publish if the payment is successful.
I have a paypal business account and I'm using standard Payment in my webpage.
I want to integrate the hosted page product named "Plataforma Integral" in my Spanish website, using an iframe. I show properly the iframe and redirect to the specified sandbox url, but when I arrive at the sandbox platform (and event in the production platform), it shows the following generic error:
Error Processing Payment
This transaction can't be processed. Please pay with another card.
I have a sandbox paypal account and this is the data I'm sending:
<form method="get" id="formNewPaypal" name="formNewPaypal" action="https://securepayments.sandbox.paypal.com/webapps/HostedSoleSolutionApp/webflow/sparta/hostedSoleSolutionProcess">
<input type="hidden" name="cmd" value="_hosted-payment">
<input type="hidden" name="business" value="[SANDBOX_USER_ID]">
<input type="hidden" name="subtotal" value="50">
<input type="hidden" name="paymentaction" value="sale">
<input type="hidden" name="return" value="[RETURN_URL]">
<input type="hidden" name="cancel_return" value="[CANCEL_URL]">
<input type="hidden" name="template" value="templateD">
<input style="display:none;" type="submit" value="Pay Now" id="submit" name="submit">
</form>
I've tried sending by POST and GET methods, and without params, and the error is always the same.
Could you tell me what's wrong or what I'm missing to send or implement? Any help will be appreciated.
For further information, please don't hesitate to ask me.
Thank you in advance.
Solved! The problem was that my sandbox account was Business and must be upgraded to Business Pro.
Now I can reach the form, but when I click the Paypal Button, It access to paypal in the main window and not in the iframe. I'll keep searching.
Thanks a lot.
I am new to Paypal integration, and I am trying to implement Paypal IPN for my android application. For make it working, I have created one web-page (Using PHP and sending to Paypal sandbox account , method (GET) ) in that I am doing payment. And I am getting payment status from this.
Actually this web page working properly and get response after do payment into Computer Browser but same thing if I am doing payment with Android Mobile browser then I am not getting any response form the Paypal for payment I have did.
I am using this url
IPN
Here is my HTML code.

<input class="btn btn-success" name="action" value="Recharge" type="submit">
</form>
So any help to this topic appreciated.
You should make sure you have IPN turned on in your PayPal settings:
Log into your PayPal account and go to Profile → Profile & Settings →
Selling Preferences → Instant Payment Notification preferences:
(alternatively click here to go directly to the page, making sure
you're logged into your PayPal account before you click the link)
Click Turn On IPN on the PayPal site.
You will then be prompted for a Notification URL, which should be
any URL - it will only be replaced by your notify_url parameter
Save your settings
If you've already done this then you need to make sure your Notification URL is accessible via the outside world, you look like you're using an IP so using something like https://www.hidemyass.com/proxy to check your site is definitely available.
If all else fails it may be an issue with PayPal and the way it decodes the notify_url from Android web browsers. I have this issue with them and sometimes the notify_url is cut short - and we suspect it's only on Android browsers.
Check your IPN history on your PayPal account and you'll see the exact URL the IPN was sent to and the status.
