Error handling in case of incorrect entry of QR-IBAN or CLASSIC-IBAN #182

Closed merlincom closed 2 years ago

merlincom commented 2 years ago

First of all thank you for the great work!

When specifying a QR-IBAN in the CLASSIC-IBAN example, processing terminates without error message. [1] Is there any way to check which type of IBAN (QR or Classic) it is and then make an if-else line break? [2] How can I provoke an error message in $referenceNumber = QrBill\Reference\QrPaymentReferenceGenerator::generate(); I have not found a solution with try { } so far.

Bei der Angabe eines QR-IBAN im CLASSIC-IBAN Beispiel bricht die Verarbeitung ohne Fehlermeldung ab. [1] Kann mann irgendow überprüfen, ob um welchen Typ von IBAN (QR oder Classic) es sich handelt und dann eine if-else Verzweigung machen? [2] Wie kann ich eine Fehlermeldung im Bereich $referenceNumber = QrBill\Reference\QrPaymentReferenceGenerator::generate(); provozieren. Ich habe mit try{ } bisher keine Lösung gefunden.

~Could you provide a code example to reproduce this bug?~ ~If I understand your description correctly, this should not happen and there is even a test to cover this case.~

Sorry, I misunderstood. New information below.

$creditorInformation = QrBill\DataGroup\Element\CreditorInformation::create($iban);
if ($creditorInformation->containsQrIban()) {
    // qr iban
} else {
    // classic iban
}

How can I provoke an error message in $referenceNumber = QrBill\Reference\QrPaymentReferenceGenerator::generate(); I have not found a solution with try { } so far.

There is an exception thrown if the provided data cannot generate a valid reference number. Otherwise it should work.

Maybe there is some specific local error in you setup.

The relevant information is this:

Fatal error: Uncaught Sprain\SwissQrBill\Exception\InvalidQrBillDataException: The provided data is not valid to generate a qr code. Use getViolations() to find details.

This means that something in your qr bill setup does not match the qr bill requirements.

So in your code below // 3. Create a full payment part for FPDF make this change:

try {
    $output = new QrBill\PaymentPart\Output\FpdfOutput\FpdfOutput($qrBill, 'de', $fpdf);
    $output
        ->setPrintable(false)
        ->getPaymentPart();
} catch (Sprain\SwissQrBill\Exception\InvalidQrBillDataException $e) {
    foreach($qrBill->getViolations() as $violation) {
        print $violation->getMessage()."\n";
    }
    exit; // of course exiting here is only useful while debugging
}

You should then see where the problem ist. Feel free to post the ouput here if you need some more help.

(PS: Your linked examples work for me without any errors. Deprecation messages are not errors, they are just helpers to let developers know where to adjust code to be compatible with future changes).

I will close this now. Feel free to re-open if there is new information.

Thanks for the hint with the try function. As expected, this results in the message:

The payment reference type "QRR" does not match with the iban type of "CH9300762011623852957".

Your answers is part of my question. Thank you very much for helping. Now the only open question is how I can make it that both QR-IBAN and CLASSIC-IBAN are processed in the same form. I will try it right away (and it works): You can test it here: https://qr-rechnung.vbbrb.ch/qr-code/FpdfOutput/fpdf-example-full-form-QR-IBAN+CLASSIC.php

$iban = str_replace( ' ', '', $_POST['qrForm-kreditor-iban'] );
$creditorInformation = QrBill\DataGroup\Element\CreditorInformation::create($iban);

if ($creditorInformation->containsQrIban()) {
    // Add payment reference for QR-IBAN
    // This is what you will need to identify incoming payments.
    $referenceNumber = QrBill\Reference\QrPaymentReferenceGenerator::generate(
            preg_replace('/[^0-9]/', '', $_POST['qrForm-kreditor-besr-id'] ),  // You receive this number from your bank (BESR-ID). Unless your bank is PostFinance, in that case use NULL.
            preg_replace('/[^0-9]/', '', $_POST['qrForm-kreditor-referenz'] ) // A number to match the payment with your internal data, e.g. an invoice number
            );

    $qrBill->setPaymentReference(
        QrBill\DataGroup\Element\PaymentReference::create(
            QrBill\DataGroup\Element\PaymentReference::TYPE_QR,
            $referenceNumber
        )
    );
} else {
    // Add payment reference CLASSIC-IBAN
    // This is what you will need to identify incoming payments.
    $qrBill->setPaymentReference(
            QrBill\DataGroup\Element\PaymentReference::create(
            QrBill\DataGroup\Element\PaymentReference::TYPE_SCOR,
            QrBill\Reference\RfCreditorReferenceGenerator::generate( preg_replace( '/[^a-zA-Z0-9]/', '', $_POST['qrForm-kreditor-referenz'] ) )
            )
    );
}

Yep, looks right to me 👍😊
