eCart PayPal Express error: Undefined index: PayPal_ECO_PayerID

Hey there, just done a test to add PayPal Express button. and getting errors below (I am also attaching various php files that may be the root of the issue).

The main files for the checkout are:
a) checkout.php (this just collects form data and writes to sessions)
b) checkout-address.php (this just collects form data and writes to sessions)
c) checkout-payment.php (this just collects form data and writes to sessions)
d) confirm-paypal.php (this is the main file that does all the server behaviour magic)
e) failure.php (this just displays the error messages for testing purposes only)

When I do a test order, it goes straight to the failure.php file after around 5 seconds. I never even see the external paypal website.

It is failing, so you can't get a result and won't be returning a payer ID. On your failure page just use:

<?php
@session_start();
var_dump($_SESSION);
?>

That will give you the information you need to figure out why it failed.

Hi, I have posted the error in private message. it seems to be an invalid argument. From the error, is there anything there you notice that could be the cause?

in my php file that does all the processing. I have the following server behaviours:
Gateway Credentials
Get Payer Profile from PayPal Express Checkout
eCart Object
Authentication for PayPal Express Checkout
Process Transaction with PayPal Express

(are the above is all I need for PayPal Express payment?
Does the form need to have an attributes? for example if you ook at my page code that calls the paypal processing file: I am using a redirect

php:
<?php

if(isset($_POST["confirmpaypal"]) || isset($_POST["confirmpaypal_x"])){
    
$WA_Redirect_URL "checkout-paypal.php";
    
$WA_Redirect_KeepQS false;
    if (
$WA_Redirect_URL != "")  {
     if (
$WA_Redirect_KeepQS && $WA_Redirect_URL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "") {
        
$WA_Redirect_URL .= ((strpos($WA_Redirect_URL'?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
     }
     
header("Location: ".$WA_Redirect_URL);
    }
}
?>


and the form is

[html]<form name="paymentform" class="standard" method="POST">[/html]

I have everything stored in sessions.

Does PayPal require anything else?

It says: ReturnURL is invalid

So look at what your return url is set to in the paypal authenticate server behavior.

I will check that, but it doesnt even get to the paypal login screen, surely it would get at least there since the return url is after.

No, it validates that the return url is a valid url syntax before accepting any other arguments. The error message is very clear.

ok I found because it didnt have the https:/// .... at the beginning... however I now get this error (I know my PayPal account is setup correctly as the WebAssist Checkout wizard test I did the other day worked fine where it was able to redirect to PayPal website.

I am attaching the new error in private message...

Now the error is on the pp_confirm page... it says: Express Checkout PayerID is missing

Is it possible the gateway settings include is too low on the page?

This is the order of my server behaviours

Gateway Credentials
Get Payer Profile from PayPal Express Checkout
eCart Object
Authentication for PayPal Express Checkout
Process Transaction with PayPal Express

also attaching the file

You shouldn't have Authenticate for Paypal on the same page as a process paypal transaction. If this is the pp_confirm page, remove that server behavior.
